  perf trace: Skip unknown syscalls when expanding strace like syscall groups (2019-06-10 17:50:04 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf record:

  Alexey Budankov:

  - Allow mixing --user-regs with --call-graph=dwarf, making sure that
    the minimal set of registers for DWARF unwinding is present in the
    set of user registers requested to be present in each sample, while
    warning the user that this may make callchains unreliable if more
    that the minimal set of registers is needed to unwind.

  yuzhoujian:

  - Add support to collect callchains from kernel or user space only,
    IOW allow setting the perf_event_attr.exclude_callchain_{kernel,user}
    bits from the command line.

perf trace:

  Arnaldo Carvalho de Melo:

  - Remove x86_64 specific syscall numbers from the augmented_raw_syscalls
    BPF in-kernel collector of augmented raw_syscalls:sys_{enter,exit}
    payloads, use instead the syscall numbers obtainer either by the
    arch specific syscalltbl generators or from audit-libs.

  - Allow 'perf trace' to ask for the number of bytes to collect for
    string arguments, for now ask for PATH_MAX, i.e. the whole
    pathnames, which ends up being just a way to speficy which syscall
    args are pathnames and thus should be read using bpf_probe_read_str().

  - Skip unknown syscalls when expanding strace like syscall groups.
    This helps using the 'string' group of syscalls to work in arm64,
    where some of the syscalls present in x86_64 that deal with
    strings, for instance 'access', are deprecated and this should not
    be asked for tracing.

  Leo Yan:

  - Exit when failing to build eBPF program.

perf config:

  Arnaldo Carvalho de Melo:

  - Bail out when a handler returns failure for a key-value pair. This
    helps with cases where processing a key-value pair is not just a
    matter of setting some tool specific knob, involving, for instance
    building a BPF program to then attach to the list of events 'perf
    trace' will use, e.g. augmented_raw_syscalls.c.

perf.data:

  Kan Liang:

  - Read and store die ID information available in new Intel processors
    in CPUID.1F in the CPU topology written in the perf.data header.

perf stat:

  Kan Liang:

  - Support per-die aggregation.

Documentation:

  Arnaldo Carvalho de Melo:

  - Update perf.data documentation about the CPU_TOPOLOGY, MEM_TOPOLOGY,
    CLOCKID and DIR_FORMAT headers.

  Song Liu:

  - Add description of headers HEADER_BPF_PROG_INFO and HEADER_BPF_BTF.

  Leo Yan:

  - Update default value for llvm.clang-bpf-cmd-template in 'man perf-config'.

JVMTI:

  Jiri Olsa:

  - Address gcc string overflow warning for strncpy()

core:

  - Remove superfluous nthreads system_wide setup in perf_evsel__alloc_fd().

Intel PT:

  Adrian Hunter:

  - Add support for samples to contain IPC ratio, collecting cycles
    information from CYC packets, showing the IPC info periodically, because
    Intel PT does not update the cycle count on every branch or instruction,
    the incremental values will often be zero.  When there are values, they
    will be the number of instructions and number of cycles since the last
    update, and thus represent the average IPC since the last IPC value.

    E.g.:

    # perf record --cpu 1 -m200000 -a -e intel_pt/cyc/u sleep 0.0001
    rounding mmap pages size to 1024M (262144 pages)
    [ perf record: Woken up 0 times to write data ]
    [ perf record: Captured and wrote 2.208 MB perf.data ]
    # perf script --insn-trace --xed -F+ipc,-dso,-cpu,-tid
    #
    <SNIP + add line numbering to make sense of IPC counts e.g.: (18/3)>

  - Allow using time ranges with Intel PT, i.e. these features, already
    present but not optimially usable with Intel PT, should be now:

        Select the second 10% time slice:

        $ perf script --time 10%/2

        Select from 0% to 10% time slice:

        $ perf script --time 0%-10%

        Select the first and second 10% time slices:

        $ perf script --time 10%/1,10%/2

        Select from 0% to 10% and 30% to 40% slices:

        $ perf script --time 0%-10%,30%-40%

cs-etm (ARM):

  Mathieu Poirier:

  - Add support for CPU-wide trace scenarios.

s390:

  Thomas Richter:

  - Fix missing kvm module load for s390.

  - Fix OOM error in TUI mode on s390

  - Support s390 diag event display when doing analysis on !s390
    architectures.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

[PATCH 06/85] perf record: Allow mixing --user-regs with --call-graph=dwarf

[Arnaldo Carvalho de Melo]

From: Alexey Budankov <alexey.budankov@linux.intel.com>

When DWARF stacks were requested and at the same time that the user
specifies a register set using the --user-regs option the full register
context was being captured on samples:

  $ perf record -g --call-graph dwarf,1024 --user-regs=IP,SP,BP -- stack_test2.g.O3

  188143843893585 0x6b48 [0x4f8]: PERF_RECORD_SAMPLE(IP, 0x4002): 23828/23828: 0x401236 period: 1363819 addr: 0x7ffedbdd51ac

   ... thread: stack_test2.g.O:23828
   ...... dso: /root/abudanko/stacks/stack_test2.g.O3

I.e. the --user-regs=IP,SP,BP was being ignored, being overridden by the
needs of --call-graph=dwarf.

After applying the change in this patch the sample data contains the
user specified register, but making sure that at least the minimal set
of register needed for DWARF unwinding (DWARF_MINIMAL_REGS) is
requested.

The user is warned that DWARF unwinding may not work if extra registers
end up being needed.

  -g call-graph dwarf,K                         full_regs
  --user-regs=user_regs                         user_regs
  -g call-graph dwarf,K --user-regs=user_regs	user_regs + DWARF_MINIMAL_REGS

  $ perf record -g --call-graph dwarf,1024 --user-regs=BP -- ls
  WARNING: The use of --call-graph=dwarf may require all the user registers, specifying a subset with --user-regs may render DWARF unwinding unreliable, so the minimal registers set (IP, SP) is explicitly forced.

Committer notes:

Detected build failures on arches where PERF_REGS_ is not available,
such as debian:experimental-x-{mips,mips64,mipsel}, fedora 24 and 30 for
ARC uClibc and glibc, reported to Alexey that provided a patch moving
the DWARF_MINIMAL_REGS from evsel.c to util/perf_regs.h, where it is
guarded by an HAVE_PERF_REGS_SUPPORT ifdef.

[PATCH 08/85] perf intel-pt: Accumulate cycle count from CYC packets

[Arnaldo Carvalho de Melo]

From: Adrian Hunter <adrian.hunter@intel.com>

In preparation for providing instructions-per-cycle (IPC) information,
accumulate cycle count from CYC packets.

Although CYC packets are optional (requires config term 'cyc' to enable
cycle-accurate mode when recording), the simplest way to count cycles is
with CYC packets.

The first complication is that cycles must be counted only when also
counting instructions.

That means when control flow packet generation is enabled i.e. between
TIP.PGE and TIP.PGD packets.

Also, sampling the cycle count follows the same rules as sampling the
timestamp, that is, not before the instruction to which the decoder is
walking is reached.

In addition, the cycle count is not accurate for any but the first
branch of a TNT packet.

[PATCH 10/85] perf intel-pt: Add support for samples to contain IPC ratio

[Arnaldo Carvalho de Melo]

From: Adrian Hunter <adrian.hunter@intel.com>

Copy the incremental instruction count and cycle count onto 'instructions'
and 'branches' samples.

Because Intel PT does not update the cycle count on every branch or
instruction, the incremental values will often be zero.

When there are values, they will be the number of instructions and
number of cycles since the last update, and thus represent the average
IPC since the last IPC value.

Note, the IPC values are low due to page faults at the beginning of
execution. The additional cycles are due to the time to enter the

[PATCH 14/85] perf intel-pt: Accumulate cycle count from TSC/TMA/MTC packets

[Arnaldo Carvalho de Melo]

From: Adrian Hunter <adrian.hunter@intel.com>

When CYC packets are not available, it is still possible to count cycles
using TSC/TMA/MTC timestamps.

As the timestamp increments in TSC ticks, convert to CPU cycles using
the current core-to-bus ratio.

Do not accumulate cycles when control flow packet generation is not
enabled, nor when time has been "lost", typically due to mwait, which is
indicated by a TSC/TMA packet that is not part of PSB+.

+Another interesting field that is not printed by default is 'ipc' which can be
+displayed as follows:
+
+	perf script --itrace=be -F+ipc
+
+There are two ways that instructions-per-cycle (IPC) can be calculated depending
+on the recording.
+
+If the 'cyc' config term (see config terms section below) was used, then IPC is
+calculated using the cycle count from CYC packets, otherwise MTC packets are
+used - refer to the 'mtc' config term.  When MTC is used, however, the values
+are less accurate because the timing is less accurate.
+
+Because Intel PT does not update the cycle count on every branch or instruction,
+the values will often be zero.  When there are values, they will be the number
+of instructions and number of cycles since the last update, and thus represent
+the average IPC since the last IPC for that event type.  Note IPC for "branches"
+events is calculated separately from IPC for "instructions" events.
+
+Also note that the IPC instruction count may or may not include the current
+instruction.  If the cycle count is associated with an asynchronous branch
+(e.g. page fault or interrupt), then the instruction count does not include the
+current instruction, otherwise it does.  That is consistent with whether or not
+that instruction has retired when the cycle count is updated.
+
+Another note, in the case of "branches" events, non-taken branches are not
+presently sampled, so IPC values for them do not appear e.g. a CYC packet with a
+TNT packet that starts with a non-taken branch.  To see every possible IPC
+value, "instructions" events can be used e.g. --itrace=i0ns
+
 While it is possible to create scripts to analyze the data, an alternative
 approach is available to export the data to a sqlite or postgresql database.
 Refer to script export-to-sqlite.py or export-to-postgresql.py for more details,

+The export process provides records with unique sequential ids which allows the
+data to be imported directly to a database and provides the relationships
+between tables.
+
+Over time it is possible to continue to expand the export while maintaining
+backward and forward compatibility, by following some simple rules:
+
+1. Because of the nature of SQL, existing tables and columns can continue to be
+used so long as the names and meanings (and to some extent data types) remain
+the same.
+
+2. New tables and columns can be added, without affecting existing SQL queries,
+so long as the new names are unique.
+
+3. Scripts that use a database (e.g. exported-sql-viewer.py) can maintain
+backward compatibility by testing for the presence of new tables and columns
+before using them. e.g. function IsSelectable() in exported-sql-viewer.py
+
+4. The export scripts themselves maintain forward compatibility (i.e. an existing
+script will continue to work with new versions of perf) by accepting a variable
+number of arguments (e.g. def call_return_table(*x)) i.e. perf can pass more
+arguments which old scripts will ignore.
+
+5. The scripting engine tests for the existence of script handler functions
+before calling them.  The scripting engine can also test for the support of new
+or optional features by checking for the existence and value of script global
+variables.

[PATCH 19/85] perf scripts python: export-to-sqlite.py: Export IPC information

[Arnaldo Carvalho de Melo]

From: Adrian Hunter <adrian.hunter@intel.com>

Export cycle and instruction counts on samples and calls tables.

Committer testing:

First runs some workload collecting intel_pt with the 'cyc' ter just for
userspace:

  [root@quaco adrian.hunter]# perf record -o simple-retpoline.perf.data -e intel_pt/cyc/u ./simple-retpoline
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.035 MB simple-retpoline.perf.data ]
  [root@quaco adrian.hunter]#

Then use the export-to-sqlite.py script to see if the changes in this
cset don't make it to break and if the changes in the db schema are the
ones expected:

  [root@quaco adrian.hunter]# perf script -i simple-retpoline.perf.data --itrace=be -s ~acme/libexec/perf-core/scripts/python/export-to-sqlite.py simple-retpoline.db branches calls
  2019-05-31 11:50:46.942710 Creating database ...
  2019-05-31 11:50:46.949663 Writing records...
  2019-05-31 11:50:47.224033 Adding indexes
  2019-05-31 11:50:47.231599 Done
  [root@quaco adrian.hunter]#

Now lets use the db:

  [root@quaco adrian.hunter]# sqlite3 simple-retpoline.db
  SQLite version 3.26.0 2018-12-01 12:34:55
  Enter ".help" for usage hints.
  sqlite> .schema samples
  CREATE TABLE samples (id integer NOT NULL PRIMARY KEY,evsel_id bigint,machine_id bigint,thread_id bigint,comm_id bigint,dso_id bigint,symbol_id bigint,sym_offset bigint,ip bigint,time bigint,cpuinteger,to_dso_id bigint,to_symbol_id bigint,to_sym_offset bigint,to_ip bigint,branch_type integer,in_tx boolean,call_path_id bigint,insn_count bigint,cyc_count bigint);
  sqlite>

Cool, the 'insn_count' and 'cyc_count' are there, now lets see if we can
use them in a query:

  sqlite> select insn_count,cyc_count from samples where cyc_count > 1500 and insn_count < 10;
  6|1507
  sqlite> select insn_count,cyc_count from samples where cyc_count > 1500;
  118|2210
  140|1516
  3783|1861
  132|1521
  6|1507
  sqlite>

Seems to work :-)

it reappear, looks buggy, minor oddity, reported to Adrian.

+<h3>Instructions per Cycle (IPC)</h3>
+If available, IPC information is displayed in columns 'insn_cnt', 'cyc_cnt' and 'IPC'.
+<p><b>Intel PT note:</b> The information applies to the blocks of code ending with, and including, that branch.
+Due to the granularity of timing information, the number of cycles for some code blocks will not be known.
+In that case, 'insn_cnt', 'cyc_cnt' and 'IPC' are zero, but when 'IPC' is displayed it covers the period
+since the previous displayed 'IPC'.
 <h3>Find</h3>
 Ctrl-F displays a Find bar which finds substrings by either an exact match or a regular expression match.
 Refer to Python documentation for the regular expression syntax.

[PATCH 25/85] perf scripts python: exported-sql-viewer.py: Select find text when find bar is activated

[Arnaldo Carvalho de Melo]

From: Adrian Hunter <adrian.hunter@intel.com>

The user probably wants to replace the find text, so select the find
text when the find bar is activated.

That is fairly standard behaviour for search text entry.

Entering text will replace the current text, but using edit keys
(arrows, home, end etc) cancels the selection and enables editing.

[PATCH 26/85] perf augmented_raw_syscalls: Tell which args are filenames and how many bytes to copy

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Since we know what args are strings from reading the syscall
descriptions in tracefs and also already mark such args to be beautified
using the syscall_arg__scnprintf_filename() helper, all we need is to
fill in this info in the 'syscalls' BPF map we were using to state which
syscalls the user is interested in, i.e. the syscall filter.

Right now just set that with PATH_MAX and unroll the syscall arg in the
BPF program, as the verifier isn't liking something clang generates when
unrolling the loop.

This also makes the augmented_raw_syscalls.c program support all arches,
since we removed that set of defines with the hard coded syscall
numbers, all should be automatically set for all arches, with the
syscall id mapping done correcly.

Doing baby steps here, i.e. just the first string arg for a syscall is
printed, syscalls with more than one, say, the various rename* syscalls,
need further work, but lets get first something that the BPF verifier
accepts before increasing the complexity

To test it, something like:

 # perf trace -e string -e /home/acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.c

With:

  # cat ~/.perfconfig
  [llvm]
	dump-obj = true
	clang-opt = -g
  [trace]
	#add_events = /home/acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.c
	show_zeros = yes
	show_duration = no
	no_inherit = yes
	show_timestamp = no
	show_arg_names = no
	args_alignment = 40
	show_prefix = yes
  #

That commented add_events line is needed for developing this
augmented_raw_syscalls.c BPF program, as if we add it via the
'add_events' mechanism so as to shorten the 'perf trace' command lines,
then we end up not setting up the -v option which precludes us having
access to the bpf verifier log :-\

[PATCH 28/85] perf augmented_raw_syscalls: Change helper to consider just the augmented_filename part

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

So that we can use it for multiple args, baby steps not to step into the
verifier toes.

In the process make sure we handle -EFAULT from bpf_prog_read_str(), as
this really is needed now that we'll handle more than one augmented
argument, i.e. if there is failure, then we have the argument that fails
have:

  (size = 0, err = -EFAULT, value = [] )

followed by the next, lets say that worked for a second pathname:

  (size = 4, err = 0, value = "/tmp" )

So we can skip the first while telling the user about the problem and
then process the second.

[PATCH 29/85] perf augmented_raw_syscalls: Move reading filename to the loop

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Almost there, next step is to copy more than one filename payload.

Probably to read syscall arg structs, etc we'll need just a variation of
this that will decide what to use, if probe_read_str() or plain
probe_read for structs, i.e. fixed size.

[PATCH 30/85] perf jvmti: Address gcc string overflow warning for strncpy()

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@redhat.com>

We are getting false positive gcc warning when we compile with gcc9 (9.1.1):

     CC       jvmti/libjvmti.o
   In file included from /usr/include/string.h:494,
                    from jvmti/libjvmti.c:5:

   cc1: all warnings being treated as errors

As per Arnaldo's suggestion use strlcpy(), which does the same thing and keeps
gcc silent.

[PATCH 31/85] perf trace: Consume the augmented_raw_syscalls payload

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

To support the SCA_FILENAME beautifier in more than one syscall arg, as
needed for syscalls such as the rename* family, we need to, after
processing one such arg, bump the augmented pointers so that the next
augmented arg don't reuse data for the previous augmented arguments.

[PATCH 32/85] perf trace: Associate more argument names with the filename beautifier

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

For instance, the rename* family uses "oldname", "newname", so check if
"name" is at the end and treat it as a filename.

[PATCH 33/85] perf trace: Exit when failing to build eBPF program

[Arnaldo Carvalho de Melo]

From: Leo Yan <leo.yan@linaro.org>

On my Juno board with ARM64 CPUs, perf trace command reports the eBPF
program building failure but the command will not exit and continue to
run.  If we define an eBPF event in config file, the event will be
parsed with below flow:

  perf_config()
    `> trace__config()
         `> parse_events_option()
              `> parse_events__scanner()
                   `-> parse_events_parse()
                         `> parse_events_load_bpf()
                              `> llvm__compile_bpf()

Though the low level functions return back error values when detect eBPF
building failure, but parse_events_option() returns 1 for this case and
trace__config() passes 1 to perf_config(); perf_config() doesn't treat
the returned value 1 as failure and it continues to parse other
configurations.  Thus the perf command continues to run even without
enabling eBPF event successfully.

This patch changes error handling in trace__config(), when it detects
failure it will return -1 rather than directly pass error value (1);
finally, perf_config() will directly bail out and perf will exit for
this case.

Committer notes:

Simplified the patch to just check directly the return of
parse_events_option() and it it is non-zero, change err from its initial
zero value to -1.

[PATCH 34/85] perf config: Bail out when a handler returns failure for a key-value pair

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

So perf_config() uses:

  int ret = 0;

  perf_config_set__for_each_entry(config_set, section, item) {
          ...
          ret = fn();
          if (ret < 0)
                  break;
  }

  return ret;

Expecting that that break will imediatelly go to function exit to return
that error value (ret).

The problem is that perf_config_set__for_each_entry() expands into two
nested for() loops, one traversing the sections in a config and the
second the items in each of those sections, so we have to change that
'break' to a goto label right before that final 'return ret'.

With that, for instance 'perf trace' now correctly bails out when a
event that is requested to be added via its 'trace.add_events'
~/.perfconfig entry gets rejected by the kernel BPF verifier:

  # perf trace ls
  event syntax error: '/home/acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.o'
                       \___ Kernel verifier blocks program loading

  (add -v to see detail)
  Run 'perf list' for a list of valid events
  Error: wrong config key-value pair trace.add_events=/home/acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.o
  #

While before it would continue and explode later, when trying to find
maps that would have been in place had that augmented_raw_syscalls.o
precompiled BPF proggie been accepted by the, humm, bast... rigorous
kernel BPF verifier 8-)

[PATCH 35/85] perf record: Add support to collect callchains from kernel or user space only

[Arnaldo Carvalho de Melo]

From: yuzhoujian <yuzhoujian@didichuxing.com>

One can just record callchains in the kernel or user space with this new
options.

We can use it together with "--all-kernel" options.

This two options is used just like print_stack(sys) or print_ustack(usr)
for systemtap.

Shown below is the usage of this new option combined with "--all-kernel"
options:

1. Configure all used events to run in kernel space and just collect
   kernel callchains.

  $ perf record -a -g --all-kernel --kernel-callchains

2. Configure all used events to run in kernel space and just collect
   user callchains.

  $ perf record -a -g --all-kernel --user-callchains

Committer notes:

Improved documentation to state that asking for kernel callchains really
is asking for excluding user callchains, and vice versa.

Further mentioned that using both won't get both, but nothing, as both
will be excluded.

[PATCH 36/85] perf evsel: Remove superfluous nthreads system_wide setup in alloc_fd()

From: Jiri Olsa <jolsa@kernel.org>

It's already setup in the only caller of this method in
perf_evsel__open(), right before calling perf_evsel__alloc_fd(), no need
to do it again.

Also it's better to have it out of the function before we move it to
libperf.

[PATCH 38/85] perf cs-etm: Configure timestamp generation in CPU-wide mode

[Arnaldo Carvalho de Melo]

From: Mathieu Poirier <mathieu.poirier@linaro.org>

When operating in CPU-wide mode tracers need to generate timestamps in
order to correlate the code being traced on one CPU with what is executed
on other CPUs.

move the packet buffer and related fields out of the decoder structure
and into the cs_etm_queue structure.

[PATCH 45/85] perf cs-etm: Introduce the concept of trace ID queues

[Arnaldo Carvalho de Melo]

From: Mathieu Poirier <mathieu.poirier@linaro.org>

In an ideal world there is one CPU per cs_etm_queue and as such, one
trace ID per cs_etm_queue.  In the real world CoreSight topologies allow
multiple CPUs to use the same sink, which translates to multiple trace
IDs per cs_etm_queue.

To deal with this a new cs_etm_traceid_queue structure is introduced to
enclose all the information related to a single trace ID, allowing a
cs_etm_queue to handle traces generated by any number of CPUs.

[PATCH 46/85] perf cs-etm: Get rid of unused cpu in struct cs_etm_queue

[Arnaldo Carvalho de Melo]

From: Mathieu Poirier <mathieu.poirier@linaro.org>

Nowadays the synthesize code is using the packet's cpu information,
making cs_etm_queue::cpu useless.  As such simply remove it.

[PATCH 49/85] perf cs-etm: Use traceID aware memory callback API

[Arnaldo Carvalho de Melo]

From: Mathieu Poirier <mathieu.poirier@linaro.org>

When working with CPU-wide traces different traceID may be found in the
same stream.  As such we need to use the decoder callback that provides
the traceID in order to know the thread context being decoded.

[PATCH 50/85] perf cs-etm: Add support for multiple traceID queues

[Arnaldo Carvalho de Melo]

From: Mathieu Poirier <mathieu.poirier@linaro.org>

When operating in CPU-wide trace mode with a source/sink topology of N:1
packets with multiple traceID will end up in the same cs_etm_queue.  In
order to properly decode packets they need to be split in different
queues, i.e one queue per traceID.

As such add support for multiple traceID per cs_etm_queue by adding a
new cs_etm_traceid_queue every time a new traceID is discovered in the
trace stream.

[PATCH 52/85] perf cs-etm: Add notion of time to decoding code

[Arnaldo Carvalho de Melo]

From: Mathieu Poirier <mathieu.poirier@linaro.org>

This patch deals with timestamp packets received from the decoding
library in order to give the front end packet processing loop a handle
on the time instruction conveyed by range packets have been executed at.

[PATCH 53/85] perf cs-etm: Add support for CPU-wide trace scenarios

[Arnaldo Carvalho de Melo]

From: Mathieu Poirier <mathieu.poirier@linaro.org>

Add support for CPU-wide trace scenarios by correlating range packets
with timestamp packets.  That way range packets received on different
ETMQ/traceID channels can be processed and synthesized in chronological
order.

[PATCH 54/85] perf cpumap: Retrieve die id information

[Arnaldo Carvalho de Melo]

From: Kan Liang <kan.liang@linux.intel.com>

There is no function to retrieve die id information of a given CPU.

Add cpu_map__get_die_id() to retrieve die id information.

[PATCH 55/85] perf header: Add die information in CPU topology

[Arnaldo Carvalho de Melo]

From: Kan Liang <kan.liang@linux.intel.com>

With the new CPUID.1F, a new level type of CPU topology, 'die', is
introduced. The 'die' information in CPU topology should be added in
perf header.

To be compatible with old perf.data, the patch checks the section size
before reading the die information. The new info is added at the end of
the cpu_topology section, the old perf tool ignores the extra data.  It
never reads data crossing the section boundary.

The new perf tool with the patch can be used on legacy kernel. Add a new
function has_die_topology() to check if die topology information is
supported by kernel. The function only check X86 and CPU 0. Assuming
other CPUs have same topology.

Use similar method for core and socket to support die id and sibling
dies string.

[PATCH 56/85] perf stat: Support per-die aggregation

[Arnaldo Carvalho de Melo]

From: Kan Liang <kan.liang@linux.intel.com>

It is useful to aggregate counts per die. E.g. Uncore becomes die-scope
on Xeon Cascade Lake-AP.

Introduce a new option "--per-die" to support per-die aggregation.

The global id for each core has been changed to socket + die id + core
id. The global id for each die is socket + die id.

Add die information for per-core aggregation. The output of per-core
aggregation will be changed from "S0-C0" to "S0-D0-C0". Any scripts
which rely on the output format of per-core aggregation probably be
broken.

For 'perf stat record/report', there is no die information when
processing the old perf.data. The per-die result will be the same as
per-socket.

Committer notes:

Renamed 'die' variable to 'die_id' to fix the build in some systems:

    CC       /tmp/build/perf/builtin-script.o
  cc1: warnings being treated as errors
  builtin-stat.c: In function 'perf_env__get_die':
  builtin-stat.c:963: error: declaration of 'die' shadows a global declaration
  util/util.h:19: error: shadowed declaration is here
  mv: cannot stat `/tmp/build/perf/.builtin-stat.o.tmp': No such file or directory

[PATCH 57/85] perf header: Rename "sibling cores" to "sibling sockets"

[Arnaldo Carvalho de Melo]

From: Kan Liang <kan.liang@linux.intel.com>

The "sibling cores" actually shows the sibling CPUs of a socket.  The
name "sibling cores" is very misleading.

[PATCH 58/85] perf tools: Apply new CPU topology sysfs attributes

[Arnaldo Carvalho de Melo]

From: Kan Liang <kan.liang@linux.intel.com>

The existing "thread_siblings" and "thread_siblings_list" attribute will
be deprecated.

Use the new CPU topology sysfs attributes, "core_cpus" and
"core_cpus_list", which are synonymous with the deprecated attributes.

Check the new name first. If not available, use the deprecated name to
be compatible with old kernel.

[PATCH 60/85] perf cs-etm: Properly set the value of 'old' and 'head' in snapshot mode

[Arnaldo Carvalho de Melo]

From: Mathieu Poirier <mathieu.poirier@linaro.org>

This patch adds the necessary intelligence to properly compute the value
of 'old' and 'head' when operating in snapshot mode.  That way we can
get the latest information in the AUX buffer and be compatible with the
generic AUX ring buffer mechanic.

Tester notes:

> Leo, have you had the chance to test/review this one? Suzuki?

Sure.  I applied this patch on the perf/core branch (with latest
commit 3e4fbf36c1e3 'perf augmented_raw_syscalls: Move reading
filename to the loop') and passed testing with below steps:

  # perf record -e cs_etm/@tmc_etr0/ -S -m,64 --per-thread ./sort &
  [1] 19097
  Bubble sorting array of 30000 elements

  # kill -USR2 19097
  # kill -USR2 19097
  # kill -USR2 19097
  [ perf record: Woken up 4 times to write data ]
  [ perf record: Captured and wrote 0.753 MB perf.data ]

[PATCH 70/85] perf intel-pt: Add intel_pt_fast_forward()

[Arnaldo Carvalho de Melo]

From: Adrian Hunter <adrian.hunter@intel.com>

Intel PT decoding is done in time order. In order to support efficient time
interval filtering, add a facility to "fast forward" towards a particular
timestamp. That involves finding the right buffer, stepping to that buffer,
and then stepping forward PSBs. Because decoding must begin at a PSB,
"fast forward" stops at the last PSB that has a timestamp before the target
timestamp.

[Arnaldo Carvalho de Melo]

From: Adrian Hunter <adrian.hunter@intel.com>

Implement the lookahead callback to let the decoder access subsequent

[PATCH 73/85] perf intel-pt: Add support for efficient time interval filtering

[Arnaldo Carvalho de Melo]

From: Adrian Hunter <adrian.hunter@intel.com>

Set up time ranges for efficient time interval filtering using the new
"fast forward" facility.

Because decoding is done in time order, intel_pt_time_filter() needs to
look only at the next start or end timestamp - refer intel_pt_next_time().

[PATCH 74/85] perf time-utils: Treat time ranges consistently

[Arnaldo Carvalho de Melo]

From: Adrian Hunter <adrian.hunter@intel.com>

Currently, options allow only 1 explicit (non-percentage) time range.
In preparation for adding support for multiple explicit time ranges,
treat time ranges consistently.

Instead of treating some time ranges as inclusive and some as excluding
the end time, treat all time ranges as inclusive. This is only a 1
nanosecond change but is necessary to treat multiple explicit time
ranges in a consistent manner.

Note, there is a later patch that adds a test for time-utils.

[PATCH 76/85] perf time-utils: Prevent percentage time range overlap

[Arnaldo Carvalho de Melo]

From: Adrian Hunter <adrian.hunter@intel.com>

Prevent percentage time range overlap. This is only a 1 nanosecond
change but makes the results more logical e.g. a sample cannot be in
both the first 10% and the second 20%.

Note, there is a later patch that adds a test for time-utils.

Correct some punctuation and spelling and correct the format to show
that the time resolution is nanoseconds not microseconds.

[PATCH 79/85] perf time-utils: Make perf_time__parse_for_ranges() more logical

[Arnaldo Carvalho de Melo]

From: Adrian Hunter <adrian.hunter@intel.com>

Explicit time ranges never contain a percent sign whereas percentage
ranges always do, so it is possible to call the correct parser.

[PATCH 81/85] perf time-utils: Add support for multiple explicit time intervals

[Arnaldo Carvalho de Melo]

From: Adrian Hunter <adrian.hunter@intel.com>

Currently only a single explicit time range is accepted. Add support for
multiple ranges separated by spaces, which requires the string to be
quoted. Update the time utils test accordingly.

[PATCH 82/85] perf test 6: Fix missing kvm module load for s390

[Arnaldo Carvalho de Melo]

From: Thomas Richter <tmricht@linux.ibm.com>

Command

   # perf test -Fv 6

fails with error

   running test 100 'kvm-s390:kvm_s390_create_vm' failed to parse
    event 'kvm-s390:kvm_s390_create_vm', err -1, str 'unknown tracepoint'
    event syntax error: 'kvm-s390:kvm_s390_create_vm'
                         \___ unknown tracepoint

when the kvm module is not loaded or not built in.

Fix this by adding a valid function which tests if the module
is loaded. Loaded modules (or builtin KVM support) have a
directory named
  /sys/kernel/debug/tracing/events/kvm-s390
for this tracepoint.

Check for existence of this directory.

[PATCH 83/85] perf report: Fix OOM error in TUI mode on s390

[Arnaldo Carvalho de Melo]

From: Thomas Richter <tmricht@linux.ibm.com>

Debugging a OOM error using the TUI interface revealed this issue
on s390:

[tmricht@m83lp54 perf]$ cat /proc/kallsyms |sort
....
00000001119b7158 B radix_tree_node_cachep
00000001119b8000 B __bss_stop
00000001119b8000 B _end
000003ff80002850 t autofs_mount	[autofs4]
000003ff80002868 t autofs_show_options	[autofs4]
000003ff80002a98 t autofs_evict_inode	[autofs4]
....

There is a huge gap between the last kernel symbol
__bss_stop/_end and the first kernel module symbol
autofs_mount (from autofs4 module).

After reading the kernel symbol table via functions:

 dso__load()
 +--> dso__load_kernel_sym()
      +--> dso__load_kallsyms()
	   +--> __dso_load_kallsyms()
	        +--> symbols__fixup_end()

the symbol __bss_stop has a start address of 1119b8000 and
an end address of 3ff80002850, as can be seen by this debug statement:

  symbols__fixup_end __bss_stop start:0x1119b8000 end:0x3ff80002850

The size of symbol __bss_stop is 0x3fe6e64a850 bytes!
It is the last kernel symbol and fills up the space until
the first kernel module symbol.

This size kills the TUI interface when executing the following
code:

  process_sample_event()
    hist_entry_iter__add()
      hist_iter__report_callback()
        hist_entry__inc_addr_samples()
          symbol__inc_addr_samples(symbol = __bss_stop)
            symbol__cycles_hist()
               annotated_source__alloc_histograms(...,
				                symbol__size(sym),
		                                ...)

This function allocates memory to save sample histograms.
The symbol_size() marco is defined as sym->end - sym->start, which
results in above value of 0x3fe6e64a850 bytes and
the call to calloc() in annotated_source__alloc_histograms() fails.

The histgram memory allocation might fail, make this failure
no-fatal and continue processing.

Output before:
[tmricht@m83lp54 perf]$ ./perf --debug stderr=1 report -vvvvv \
					      -i ~/slow.data 2>/tmp/2
[tmricht@m83lp54 perf]$ tail -5 /tmp/2

   	=> nr_samples: 1, period: 526008
[tmricht@m83lp54 perf]$

There is no error about failed memory allocation and the TUI interface
shows all entries.

[PATCH 84/85] perf report: Support s390 diag event display on x86

[Arnaldo Carvalho de Melo]

From: Thomas Richter <tmricht@linux.ibm.com>

Perf report fails to display s390 specific event numbered bd000
on an x86 platform. For example on s390 this works without error:

[root@m35lp76 perf]# uname -m
s390x
[root@m35lp76 perf]# ./perf record -e rbd000 -- find / >/dev/null
[ perf record: Woken up 3 times to write data ]
[ perf record: Captured and wrote 0.549 MB perf.data ]
[root@m35lp76 perf]# ./perf report -D --stdio  > /dev/null
[root@m35lp76 perf]#

Transfering this perf.data file to an x86 platform and executing
the same report command produces:

[root@f29 perf]# uname -m
x86_64
[root@f29 perf]# ./perf report -i ~/perf.data.m35lp76 --stdio
interpreting bpf_prog_info from systems with endianity is not yet supported
interpreting btf from systems with endianity is not yet supported
0x8c890 [0x8]: failed to process type: 68
Error:
failed to process sample

Event bd000 generates auxiliary data which is stored in big endian
format in the perf data file.
This error is caused by missing endianess handling on the x86 platform
when the data is displayed. Fix this by handling s390 auxiliary event
data depending on the local platform endianness.

Output after on x86:

[root@f29 perf]# ./perf report -D -i ~/perf.data.m35lp76 --stdio > /dev/null
interpreting bpf_prog_info from systems with endianity is not yet supported
interpreting btf from systems with endianity is not yet supported
[root@f29 perf]#

Committer notes:

Fix build breakage on older systems, such as CentOS:6 where using
nesting calls to the endian.h macros end up redefining local variables:

  util/s390-cpumsf.c: In function 's390_cpumsf_trailer_show':
  util/s390-cpumsf.c:333: error: declaration of '__v' shadows a previous local
  util/s390-cpumsf.c:333: error: shadowed declaration is here
  util/s390-cpumsf.c:333: error: declaration of '__x' shadows a previous local
  util/s390-cpumsf.c:333: error: shadowed declaration is here
  util/s390-cpumsf.c:334: error: declaration of '__v' shadows a previous local
  util/s390-cpumsf.c:334: error: shadowed declaration is here
  util/s390-cpumsf.c:334: error: declaration of '__x' shadows a previous local
  util/s390-cpumsf.c:334: error: shadowed declaration is here

  [perfbuilder@455a63ef60dc perf]$ gcc -v |& tail -1
  gcc version 4.4.7 20120313 (Red Hat 4.4.7-23) (GCC)
  [perfbuilder@455a63ef60dc perf]$

Since there are several uses of

  be64toh(te->flags)

Introduce a variable to hold that and then use it, avoiding this case
that causes the above problems:

  -       local.bsdes = be16toh((be64toh(te->flags) >> 16 & 0xffff));
  +       local.bsdes = be16toh((flags >> 16 & 0xffff));

Its the same construct used in s390_cpumsf_diag_show() where we have a
'word' variable that is used just once, s390_cpumsf_basic_show() has
lots of uses and also uses a variable to hold the result of be16toh().

Some of those temp variables needed to be converted from 'unsigned long'
to 'unsigned long long' so as to build on 32-bit arches such as
debian:experimental-x-mipsel, the android NDK ones and
fedora:24-x-ARC-uClibc.

[PATCH 85/85] perf trace: Skip unknown syscalls when expanding strace like syscall groups

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

We have $INSTALL_DIR/share/perf-core/strace/groups/string files with
syscalls that should be selected when 'string' is used, meaning, in this
case, syscalls that receive as one of its arguments a string, like a
pathname.

But those were first selected and tested on x86_64, and end up failing
in architectures where some of those syscalls are not available, like
the 'access' syscall on arm64, which makes using 'perf trace -e string'
in such archs to fail.

Since this the routine doing the validation is used only when reading
such files, do not fail when some syscall is not found in the
syscalltbl, instead just use pr_debug() to register that in case people
are suspicious of problems.

Now using 'perf trace -e string' should work on arm64, selecting only
the syscalls that have a string and are available on that architecture.

  perf flamegraph: Use /bin/bash for report and record scripts (2020-05-05 16:35:32 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf record:

  - Introduce --switch-output-event to use arbitrary events to be setup
    and read from a side band thread and, when they take place a signal
    be sent to the main 'perf record' thread, reusing the --switch-output
    code to take perf.data snapshots from the --overwrite ring buffer, e.g.:

	# perf record --overwrite -e sched:* \
		      --switch-output-event syscalls:*connect* \
		      workload

    will take perf.data.YYYYMMDDHHMMSS snapshots up to around the
    connect syscalls.

  Stephane Eranian:

  - Add --num-synthesize-threads option to control degree of parallelism of the
    synthesize_mmap() code which is scanning /proc/PID/task/PID/maps and can be
    time consuming. This mimics pre-existing behaviour in 'perf top'.

Intel PT:

  Adrian Hunter:

  - Add support for synthesizing branch stacks for regular events (cycles,
    instructions, etc) from Intel PT data.

perf bench:

  Ian Rogers:

  - Add a multi-threaded synthesize benchmark.

  - Add kallsyms parsing benchmark.

  Tommi Rantala:

  - Fix div-by-zero if runtime is zero.

perf synthetic events:

  - Remove use of sscanf from /proc reading when parsing pre-existing
    threads to generate synthetic PERF_RECORD_{FORK,MMAP,COMM,etc} events.

tools api:

  - Add a lightweight buffered reading API.

libsymbols:

  - Parse kallsyms using new lightweight buffered reading io API.

perf parse-events:

  - Fix memory leaks found on parse_events.

perf mem2node:

  - Avoid double free related to realloc().

perf stat:

  Jin Yao:

  - Zero all the 'ena' and 'run' array slot stats for interval mode.

  - Improve runtime stat for interval mode

  Kajol Jain:

  - Enable Hz/hz printing for --metric-only option

  - Enhance JSON/metric infrastructure to handle "?".

perf tests:

  Kajol Jain:

  - Added test for runtime param in metric expression.

  Tommi Rantala:

  - Fix data path in the session topology test.

perf vendor events power9:

  Kajol Jain:

 - Add hv_24x7 socket/chip level metric events

Coresight:

  Leo Yan:

  - Move definition of 'traceid_list' global variable from header file.

  Mike Leach:

  - Update to build with latest opencsd version.

perf pmu:

  Shaokun Zhang:

  - Fix function name in comment, its get_cpuid_str(), not get_cpustr()

  Stephane Eranian:

  - Add perf_pmu__find_by_type() helper

perf script:

  Stephane Eranian:

  - Remove extraneous newline in perf_sample__fprintf_regs().

  Ian Rogers:

  - Avoid NULL dereference on symbol.

tools feature:

  Stephane Eranian:

  - Add support for detecting libpfm4.

perf symbol:

  Thomas Richter:

  - Fix kernel symbol address display in TUI verbose mode.

perf cgroup:

  Tommi Rantala:

  - Avoid needless closing of unopened fd

libperf:

  He Zhe:

  - Add NULL pointer check for cpu_map iteration and NULL
    assignment for all_cpus.

  Ian Rogers:

  - Fix a refcount leak in evlist method.

  Arnaldo Carvalho de Melo:

  - Rename the code in tools/perf/util, i.e. perf tooling specific, that
    operates on 'struct evsel' to evsel__, leaving the perf_evsel__
    namespace for the routines in tools/lib/perf/ that operate on
    'struct perf_evsel__'.

tools/perf specific libraries:

  Konstantin Khlebnikov:

  - Fix reading new topology attribute "core_cpus"

  - Simplify checking if SMT is active.

perf flamegraph:

  Arnaldo Carvalho de Melo:

  - Use /bin/bash for report and record scripts, just like all other
    such scripts, fixing a package dependency bug in a Linaro
    OpenEmbedded build checker.

perf evlist:

  Jagadeesh Pagadala:

  - Remove duplicate headers.

Miscelaneous:

  Zou Wei:

  - Remove unneeded semicolon in libtraceevent, 'perf c2c' and others.

  - Fix warning assignment of 0/1 to bool variable in 'perf report'

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Ubuntu 19.10 and debian experimental are failing when linking against
libllvm, which isn't the default, needs to be investigated, haven't
tested with CC=gcc, but should be the same problem:

oops, make that this instead:


commit b3a63d0c17e6e1d23a6b44502b55f066adfd8e6a
Author: Arnaldo Carvalho de Melo <acme@redhat.com>
Date:   Tue May 5 13:33:12 2020 -0300

    perf flamegraph: Use /bin/bash for report and record scripts
    
    As all the other tools/perf/scripts/python/bin/*-{report,record}
    scripts, fixing the this problem reported by Daniel Diaz:
    
      Our OpenEmbedded builds detected an issue with 5287f9269206 ("perf
      script: Add flamegraph.py script"):
        ERROR: perf-1.0-r9 do_package_qa: QA Issue:
      /usr/libexec/perf-core/scripts/python/bin/flamegraph-report contained
      in package perf-python requires /usr/bin/sh, but no providers found in
      RDEPENDS_perf-python? [file-rdeps]
    
      This means that there is a new binary pulled in in the shebang line
      which was unaccounted for: `/usr/bin/sh`. I don't see any other usage
      of /usr/bin/sh in the kernel tree (does not even exist on my Ubuntu
      dev machine) but plenty of /bin/sh. This patch is needed:

Thanks for the reminder, I've just added this to my tree:

commit c74ab13a30d3bec443c116e25b611255c58f32c0
Author: Arnaldo Carvalho de Melo <acme@redhat.com>

    perf flamegraph: Use /bin/bash for report script
    
    As all the other tools/perf/scripts/python/bin/*-report scripts, fixing
    the this problem reported by Daniel Diaz:
    
      Our OpenEmbedded builds detected an issue with 5287f9269206 ("perf

      RDEPENDS_perf-python? [file-rdeps]
    
      This means that there is a new binary pulled in in the shebang line
      which was unaccounted for: `/usr/bin/sh`. I don't see any other usage

Just a gentle reminder that this can still be fixed in today's

yeah, the flamegraph scripts are the outliers, there, everything else is

Our OpenEmbedded builds detected an issue with 5287f9269206 ("perf
script: Add flamegraph.py script"):
  ERROR: perf-1.0-r9 do_package_qa: QA Issue:
/usr/libexec/perf-core/scripts/python/bin/flamegraph-report contained

This means that there is a new binary pulled in in the shebang line
which was unaccounted for: `/usr/bin/sh`. I don't see any other usage
of /usr/bin/sh in the kernel tree (does not even exist on my Ubuntu
dev machine) but plenty of /bin/sh. This patch is needed:

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same
problem:

  perf dso: Fix dso comparison (2020-03-24 10:57:38 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf report/top:

  Jin Yao:

  - Support annotation of unresolved symbols, just using its addresses.

  - Print addr_location.al_addr when finding a map but not a symbol, so
    that we have the address relative to the map which is what objdump
    produces, then we can match the output of perf and objdump for such
    unresolved addresses.

  - Allow sorting by non-group leaders when working with multiple events,
    be it in a explicit group, i.e. an event list surrounded by {} (e.g.
    'perf record -e '{cycles,instructions,cache-misses}', or without,
    using --group in 'perf report', e.g.:

        perf record -e cycles,instructions,cache-misses
	perf report --group --group-sort-idx 1

     That '1' will ask for the output to be sorted by 'instructions', not
     the default 'cycles'.

  - Add hotkeys to interactively resort the output when using multiple
    events, '0', '1', ... '9' to resort by the nth event, just like when
    using --group-sort-idx, as explained above.

perf stat:

  Jin Yao:

  - Align the output for interval aggregation mode.

event parsing:

  Ian Rogers:

  - Fix 3 use after frees found with clang ASAN.

perf tools:

  Jiri Olsa:

  - Unify a bit the build directory output.

perf tests:

  John Garry:

  - Add PMU events tests, checking that JSON files are properly parsed.

perf stat:

  Kajol Jain:

  - Fix printing event names of metric group with multiple events incase of overlapping events.

perf symbols:

  Leo Yan:

  - Consolidate symbol fixup issue.

vendor events AMD:

  Vijay Thakkar:

  - Restrict model detection for zen1 based processors

  - Add Zen2 events.

  - Update Zen1 events to V2.

perf cpumap:

  Christophe JAILLET:

 - Fix snprintf overflow check

DSOs:

  Ravi Bangoria:

  - Fix dso comparison wrt IDs (maj, min, etc), that had made 'perf archive'
    stop working when build-ids were not being collected.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same
problem:

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux and debian:experimental are failing when due to:

  `.gnu.debuglto_.debug_macro' referenced in section `.gnu.debuglto_.debug_macro' of /tmp/build/perf/util/scripting-engines/perf-in.o: defined in discarded section `.gnu.debuglto_.debug_macro[wm4.stdcpredef.h.19.8dc41bed5d9037ff9622e015fb5f0ce3]' of /tmp/build/perf/util/scripting-engines/perf-in.o

Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same problem:

+ make ARCH= CROSS_COMPILE= EXTRA_CFLAGS= LIBCLANGLLVM=1 -C /git/linux/tools/perf O=/tmp/build/perf CC=clang

  It builds ok with the default set of options.

  perf block-info: Support color ops to print block percents in color (2020-03-09 21:43:25 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf stat:

  Jin Yao:

  - Show percore counts in per CPU output.

perf report:

  Jin Yao:

  - Allow selecting which block info columns to report and its order.

  - Support color ops to print block percents in color.

  - Fix wrong block address comparison in block_info__cmp().

perf annotate:

  Ravi Bangoria:

  - Get rid of annotation->nr_jumps, unused.

expr:

  Jiri Olsa:

  - Move expr lexer to flex.

llvm:

  Arnaldo Carvalho de Melo:

  - Add debug hint message about missing kernel-devel package.

core:

  Kan Liang:

  - Initial patches to support the recently added PERF_SAMPLE_BRANCH_HW_INDEX
    kernel feature.

  - Add check for unexpected use of reserved membrs in event attr, so that in
    the future older perf tools will complain instead of silently try to process
    unknown features.

libapi:

  Namhyung Kim:

  - Adopt cgroupsfs_find_mountpoint() from tools/perf/util/.

libperf:

  Michael Petlan:

  - Add counting example.

libtraceevent:

   Steven Rostedt (VMware):

  - Remove extra '\n' in print_event_time().

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when due to:

  `.gnu.debuglto_.debug_macro' referenced in section `.gnu.debuglto_.debug_macro' of /tmp/build/perf/util/scripting-engines/perf-in.o: defined in discarded section `.gnu.debuglto_.debug_macro[wm4.stdcpredef.h.19.8dc41bed5d9037ff9622e015fb5f0ce3]' of /tmp/build/perf/util/scripting-engines/perf-in.o

Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same problem:

+ make ARCH= CROSS_COMPILE= EXTRA_CFLAGS= LIBCLANGLLVM=1 -C /git/linux/tools/perf O=/tmp/build/perf CC=clang

  It builds ok with the default set of options.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when due to:

  `.gnu.debuglto_.debug_macro' referenced in section `.gnu.debuglto_.debug_macro' of /tmp/build/perf/util/scripting-engines/perf-in.o: defined in discarded section `.gnu.debuglto_.debug_macro[wm4.stdcpredef.h.19.8dc41bed5d9037ff9622e015fb5f0ce3]' of /tmp/build/perf/util/scripting-engines/perf-in.o

OpenMandriva Cooker works well with gcc, uncovers a bug where we have to
get compiler-clang.h from the kernel sources, will be fixed soon.

With the update of linux/linkage.h to move from ENTRY()/ENDPROC() to
SYM_FUNC_START()/etc some of the older containers can't be used with clang,
as the minimum version for the constructs used in the new linkage.h is 3.5,
older versions (3.4, 3.4.2, etc) end up with:

  bench/../../arch/x86/lib/memcpy_64.S:44:14: error: unexpected token in '.type' directive
  .type MEMCPY STT_FUNC ; .size MEMCPY, .-MEMCPY
               ^

Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same problem:

+ make ARCH= CROSS_COMPILE= EXTRA_CFLAGS= LIBCLANGLLVM=1 -C /git/linux/tools/perf O=/tmp/build/perf CC=clang

  It builds ok with the default set of options.

  tools lib: Fix builds when glibc contains strlcpy() (2020-01-06 11:46:10 -0300)

----------------------------------------------------------------
perf/core improvements and fixes.

perf record:

  Alexey Budankov:

  - Adapt affinity for machines with #CPUs > 1K to overcome current 1024 CPUs
    mask size limitation of cpu_set_t type.

perf report/top TUI:

  Arnaldo Carvalho de Melo:

  - Make ENTER consistently present the pop up menu with and without call
    chains, to eliminate confusion. The menu continues available at all times
    use 'm' and '+' can be used to toggle just one call chain level, 'e' for all
    the call chains for a top level histogram entry and 'E' to expand all call
    chains in all top level entries. Extra info about these options was added to
    the pop up menu entries. Pressing 'k' serves as special hotkey to go straight
    to the main vmlinux entries, to avoid having to press enter and then select
    "Zoom into the kernel DSO".

perf sched timehist:

  David Ahern:

  - Add support for filtering on CPU.

perf tests:

  Arnaldo Carvalho de Melo:

  - Show expected versus obtained values in bp_signal test.

libperf:

  Jiri Olsa:

  - Move to tools/lib/perf.

  - Add man pages.

libapi:

  Andrey Zhizhikin:

  - Fix gcc9 stringop-truncation compilation error.

tools lib:

  Vitaly Chikunov:

  - Fix builds when glibc contains strlcpy(), which is the case for ALT Linux.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when due to:

  `.gnu.debuglto_.debug_macro' referenced in section `.gnu.debuglto_.debug_macro' of /tmp/build/perf/util/scripting-engines/perf-in.o: defined in discarded section `.gnu.debuglto_.debug_macro[wm4.stdcpredef.h.19.8dc41bed5d9037ff9622e015fb5f0ce3]' of /tmp/build/perf/util/scripting-engines/perf-in.o

OpenMandriva Cooker works well with gcc, uncovers a bug where we have to
get compiler-clang.h from the kernel sources, will be fixed soon.

With the update of linux/linkage.h to move from ENTRY()/ENDPROC() to
SYM_FUNC_START()/etc some of the older containers can't be used with clang,
as the minimum version for the constructs used in the new linkage.h is 3.5,
older versions (3.4, 3.4.2, etc) end up with:

  bench/../../arch/x86/lib/memcpy_64.S:44:14: error: unexpected token in '.type' directive
  .type MEMCPY STT_FUNC ; .size MEMCPY, .-MEMCPY

  libtraceevent: Copy pkg-config file to output folder when using O= (2019-12-02 21:58:20 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf report/top:

  - Fix segfault due to missing initialization of recently introduced
    struct map_symbol 'maps' field in append_inlines(), when running
    with DWARF callchains.

perf stat:

  Andi Kleen:

  - Affinity based optimizations for sessions with many events in
    machines with large core counts, avoiding excessive number of IPIs.

libtraceevent:

  - Sudip Mukherjee:

  - Fix installation with O=.

  - Copy pkg-config file to output folder when using O=.

perf bench:

  Arnaldo Carvalho de Melo:

  - Update the copies of x86's mem{cpy,set}_64.S, and because that
    now uses new stuff in linux/linkage.h, update that header too, which
    made the minimal clang version to build perf to be 3.5, as
    3.4 as found in some of the container images used to test build perf
    can't grok STT_FUNC as a token in .type lines.

ABI headers:

  Arnaldo Carvalho de Melo:

  - Sync x86's msr-index.h copy with the kernel sources, resulting
    in new MSRs to be usable in filter expressions in 'perf trace',
    such as IA32_TSX_CTRL.

  - Sync linux/fscrypt.h, linux/stat.h, sched.h and the kvm headers.

perf trace:

  Arnaldo Carvalho de Melo:

  - Add CLEAR_SIGHAND support for clone's flags arg

perf kvm:

  Arnaldo Carvalho de Melo:

  - Clarify the 'perf kvm' -i and -o command line options

perf test:

  Ian Rogers:

  - Move test functionality in to a 'perf test' entry.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

OpenMandriva Cooker works well with gcc, uncovers a bug where we have to
get compiler-clang.h from the kernel sources, will be fixed soon.

With the update of linux/linkage.h to move from ENTRY()/ENDPROC() to
SYM_FUNC_START()/etc some of the older containers can't be used with clang,
as the minimum version for the constructs used in the new linkage.h is 3.5,
older versions (3.4, 3.4.2, etc) end up with:

  bench/../../arch/x86/lib/memcpy_64.S:44:14: error: unexpected token in '.type' directive
  .type MEMCPY STT_FUNC ; .size MEMCPY, .-MEMCPY
               ^

Finally the build-tests and container tests were performed with the following
two fixes (different sha, same contents), that are not in this patch series,
will go thru the bpf/net trees.

The 'perf test' was performed with what is in this series tho.

[GIT PULL] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo/Thomas,

	Please consider pulling, this has a merge with mainline to pick
bpf stuff, and the build-test and container build tests were performed
with two extra patches I cooked to fix libbpf issuers in some odd 32-bit
arches and on generation of some bpf helpers headers that will hit
mainline via the bpf/net trees.

Best regards,

- Arnaldo

Test results at the end of this message, as usual.

The following changes since commit 2ea352d5960ad469f5712cf3e293db97beac4e01:

  Merge remote-tracking branch 'torvalds/master' into perf/core (2019-11-26 11:06:19 -0300)

  - Use llabs() with 64-bit values, fixing the build in some 32-bit
    architectures.

perf pmu:

  Andi Kleen:

  - Use file system cache to optimize sysfs access.

x86:

  Adrian Hunter:

  - Add some more Intel instructions to the opcode map and to the perf
    test entry:

      gf2p8affineinvqb, gf2p8affineqb, gf2p8mulb, v4fmaddps,
      v4fmaddss, v4fnmaddps, v4fnmaddss, vaesdec, vaesdeclast, vaesenc,
      vaesenclast, vcvtne2ps2bf16, vcvtneps2bf16, vdpbf16ps,

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

OpenMandriva Cooker works well with gcc, uncovers a bug where we have to
get compiler-clang.h from the kernel sources, will be fixed soon.

Finally the build-tests and container tests were performed with the following
two fixes, that are not in this patch series, will go thru the bpf/net trees:

  $ git log --oneline -2
  e1bc15a8e7d1 (HEAD -> perf/core) libbpf: Use PRIu64 for sym->st_value to fix build on 32-bit arches
  0d0f9df96c5a libbpf: Fix up generation of bpf_helper_defs.h
  $ 

The 'perf test' was performed with what is in this series tho.

  perf parse: Fix potential memory leak when handling tracepoint errors (2019-11-22 10:48:14 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

  Jin Yao:

  - Allow entering the annotation view (symbol source/assembly +
    overhead/cycles/etc column) from the 'perf report --total-cycles'
    interface.

    Then press 'A' or Enter on one of those lines, just like with 'perf top', say
    the top one: [msr.h:105 -> msr.h:166], then this shows up:

    We need to improve this to show the source code line numbers in the
    annotation view, so one can go from that program block to the annotation view
    and see those source code line numbers straight away.

auxtrace/Intel PT:

  Adrian Hunter:

  - Add support for AUX area sampling, requires new functionality that
    will land in 5.5, its already in tip.

    This includes kernel capability querying so that it fails gracefully
    with older kernels, duimping aux area samples in 'perf report -D' and
    'perf script'.

perf.data:

  Alexey Budankov:

  - Fix decompression of PERF_RECORD_COMPRESSED records.

core:

  Arnaldo Carvalho de Melo:

  - Use the 'dcacheline' cmp routine to find the right DSOs taking into
    account the 'maj', 'min', 'ino' and 'ino_generation', that got moved
    from 'struct map' to 'struct dso', where it belongs.

    This further reduces the size of 'struct map', there is still more
    work to do to maybe get it to max one cacheline.

libtraceevent:

  Hewenliang:

  - Fix memory leakage in copy_filter_type().

  Sudip Mukherjee:

  - Fix header installation.

perf parse:

  Ian Rogers :

  - Fix potential memory leak when handling tracepoint errors, found using
    LLVM's libFuzzer.

perf probe:

  Colin Ian King:

  - Fix spelling mistake "addrees" -> "address".

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Manjaro got fixed by adding the 'gettext' package, that provides a
library needed by bison but not present in its dependencies list, i.e. a
distro bug.

cooker is failing with:

Still needs investigating, new image, just leaving it here for
documentation purposes, maybe related to it using the most recent gcc
and clang versions?

[GIT PULL] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo/Thomas,

	Please consider pulling,

Best regards,

- Arnaldo


The following changes since commit e1e9b78d3957a267346a86c8f2c433f6a332af65:

  perf parse: Use YYABORT to clear stack after failure, plugging leaks (2019-11-12 08:34:16 -0300)

are available in the Git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-core-for-mingo-5.5-20191119

for you to fetch changes up to a910e4666d61712840c78de33cc7f89de8affa78:

  perf parse: Report initial event parsing error (2019-11-18 19:14:29 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

x86/insn:

  Adrian Hunter:

  - Add some more Intel instructions to the opcode map:

        cldemote, encls, enclu, enclv, enqcmd, enqcmds, movdir64b,
        movdiri, pconfig, tpause, umonitor, umwait, wbnoinvd.

  - The instruction decoding can be tested using the perf tools'
    "x86 instruction decoder - new instructions" test as folllows:

    $ perf test -v "new " 2>&1 | grep -i cldemote
    Decoded ok: 0f 1c 00                    cldemote (%eax)
    Decoded ok: 0f 1c 05 78 56 34 12        cldemote 0x12345678
    Decoded ok: 0f 1c 84 c8 78 56 34 12     cldemote 0x12345678(%eax,%ecx,8)
    Decoded ok: 0f 1c 00                    cldemote (%rax)
    Decoded ok: 41 0f 1c 00                 cldemote (%r8)
    Decoded ok: 0f 1c 04 25 78 56 34 12     cldemote 0x12345678
    Decoded ok: 0f 1c 84 c8 78 56 34 12     cldemote 0x12345678(%rax,%rcx,8)
    Decoded ok: 41 0f 1c 84 c8 78 56 34 12  cldemote 0x12345678(%r8,%rcx,8)
    $ perf test -v "new " 2>&1 | grep -i tpause
    Decoded ok: 66 0f ae f3                 tpause %ebx
    Decoded ok: 66 0f ae f3                 tpause %ebx
    Decoded ok: 66 41 0f ae f0              tpause %r8d

callchains:

  Adrian Hunter:

  - Fix segfault in thread__resolve_callchain_sample().

perf probe:

  - Line fixes to show only lines where probes can be used with 'perf probe -L',
    and when reporting them via 'perf probe -l'.

  - Support multiprobe events.

perf scripts python:

  Adrian Hunter:

  - Fix use of TRUE with SQLite < 3.23 in exported-sql-viewer.py.

perf maps:

  - Trim 'struct map' by removing the rb_node member for sorting
    by map name, as that is only needed for processing kernel maps,
    and only when classifying symbols by section at load time.
    Sort them by name using qsort() and do lookups using bsearch()
    when map_groups__find_by_name() is used.

perf parse:

  Ian Rogers:

  - Report initial event parsing error, providing a less cryptic message
    to state that a PMU wasn't found in the system.

perf vendor events:

  James Clark:

  - Fix commas so that PMU event files for arm64, power8 and power nine
    become valid JSON.

libtraceevent:

  perf parse: Use YYABORT to clear stack after failure, plugging leaks (2019-11-12 08:34:16 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf record:

  Ravi Bangoria:

  - Provide an option to print perf_event_open args and syscall return value.
    This was already possible using -v, but then lots of other debug info
    would be output as well, provide a way to show just the syscall args
    and return value, e.g.:

      # perf --debug perf-event-open=1 record
      perf_event_attr:
        size                             112
        { sample_period, sample_freq }   4000
        sample_type                      IP|TID|TIME|PERIOD
        read_format                      ID
        disabled                         1
        inherit                          1
      <SNIP>
        ksymbol                          1
        bpf_event                        1
      ------------------------------------------------------------
      sys_perf_event_open: pid 4308  cpu 0  group_fd -1  flags 0x8 = 4

core:

- Remove map->groups, we can get that information in other ways, reduces
  the size of a key data structure and paves the way to have it shared
  by multiple threads.

- Use 'struct map_symbol' in more places, where we already were using a
  'struct map' + 'struct symbol', this helps passing that usual pair of
  information across callchain, browser code, etc.

- Add 'struct map_groups' (where the map_symbol->map is) to 'struct map_symbol',
  to ease annotation code, for instance, where we call from functions in one map
  we're browsing to functions in another DSO, mapped in another 'struct map'.

event parsing:

  Ian Rogers:

  - Use YYABORT to clear stack after failure, plugging leaks

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Manjaro is failing due to some missing library related to bison, looks like
a distro bug.

  perf report: Sort by sampled cycles percent per block for tui (2019-11-07 10:14:48 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf report:

  Jin Yao:

  - Introduce --total-cycles, for basic block profiling, further using data
    obtained from LBR, an example should suffice:

      # perf record -b
      ^C[ perf record: Woken up 595 times to write data ]
      [ perf record: Captured and wrote 156.672 MB perf.data (196873 samples) ]

      # perf evlist -v
      cycles: size: 112, { sample_period, sample_freq }: 4000, sample_type: IP|TID|TIME|CPU|PERIOD|BRANCH_STACK, read_format: ID, disabled: 1, inherit: 1, mmap: 1, comm: 1, freq: 1, task: 1, precise_ip: 3, sample_id_all: 1, exclude_guest: 1, mmap2: 1, comm_exec: 1, ksymbol: 1, bpf_event: 1, branch_sample_type: ANY

      # perf report --total-cycles --stdio
      # To display the perf.data header info, please use --header/--header-only options.
      #
      # Total Lost Samples: 0

perf record:

  Adrian Hunter:

  - Allow storing perf.data in a directory together with a copy of /proc/kcore.

  Jiwei Sun:

  - Add support for limit perf output file size, i.e.:

    # perf record --all-cpus -F 10000 --max-size=4M sleep 10h
    [ perf record: perf size limit reached (4097 KB), stopping session ]
    [ perf record: Woken up 6 times to write data ]
    [ perf record: Captured and wrote 4.048 MB perf.data (54094 samples) ]
    Terminated
    # ls -lah perf.data
    -rw-------. 1 root root 4.1M Nov  7 15:27 perf.data
    #

perf stat:

  Jiri Olsa:

  - Add --per-node agregation support:

    In live mode:

      # perf stat  -a -I 1000 -e cycles --per-node
      #           time node   cpus             counts unit events
           1.000542550 N0       20          6,202,097      cycles
           1.000542550 N1       20            639,559      cycles
           2.002040063 N0       20          7,412,495      cycles
           2.002040063 N1       20          2,185,577      cycles
           3.003451699 N0       20          6,508,917      cycles
           3.003451699 N1       20            765,607      cycles
      ...

    Or in the record/report stat session:

      # perf stat record -a -I 1000 -e cycles
      #           time             counts unit events

perf probe:

  Masami Hiramatsu:

  Various fixes related to recent additions to the DWARF format:

  - Fix to find range-only function instance

  - Walk function lines in lexical blocks

  - Fix to show function entry line as probe-able

  - Fix wrong address verification

  - Fix to probe a function which has no entry pc

  - Fix to probe an inline function which has no entry pc

  - Fix to list probe event with correct line number

  - Fix to show inlined function callsite without entry_pc

  - Fix to show ranges of variables in functions without entry_pc

  - Return a better scope DIE if there is no best scope

  - Skip end-of-sequence and non statement lines

  - Filter out instances except for inlined subroutine and subprogram

  - Fix to show calling lines of inlined functions

  - Skip overlapped location on searching variables

perf inject:

  Adrian Hunter:

  - Do not strip evsels with --strip, as they are needed for create_gcov
    (see the autofdo example in tools/perf/Documentation/intel-pt.txt).

Intel PT:

  Adrian Hunter:

  - Intel PT uses an auxtrace_cache to store the results of code-walking, to avoid
    repeated decoding. Add an auxtrace_cache__remove to handle text poke events.

core:

  Andi Kleen:

  - Always preserve errno while cleaning up perf_event_open failures.

llvm:

  Arnaldo Carvalho de Melo:

  - No need to tell that the request for saving a .o file for BPF events, as
    expressed in ~/.perfconfig was satisfied, make that a debug message.

perf vendor events:

Intel:

  Haiyan Song:

  - Update CascadelakeX events to v1.05.

  - Update all the Intel JSON metrics from TMAM 3.6.

Treewide:

  Ian Rogers:

  - Improve error paths, plugging leaks found using LLVM tools
    such as libFuzzer.

jevents:

  Yunfeng Ye:

  - Fix resource leak in process_mapfile() and main()

perf kvm:

  Igor Lubashev:

  - Use evlist layer api when possible.

libsubcmd:

  James Clark:

  - Move EXTRA_FLAGS to the end to allow overriding existing flags.

  - Use -O0 with DEBUG=1

perf diff:

  Jin Yao:

  - Don't use hack to skip column length calculation

CoreSight ETM:

  Leo yan:

  - Fix definition of macro TO_CS_QUEUE_NR

ARM64:

  John Garry:

  - Do not try to include libelf header files when its feature detection
    failed, fixing the cross build for ARM64.

perf tests:

  Leo Yan:

  - Fix out of bounds memory access in the backward ring buffer test.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Manjaro is failing due to some missing library related to bison, looks like
a distro bug.

  perf trace: Use STUL_STRARRAY_FLAGS with mmap (2019-10-19 15:35:02 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf trace:

- Add syscall failure stats to -s/--summary and -S/--with-summary, also works in
  combination with specifying just a set of syscalls, see below first with
  -s/--summary, then with -S/--with-summary just for the syscalls we saw failing
  with -s:

    # perf trace -s sleep 1

  - Filter own pid to avoid a feedback look in 'perf trace record -a'

  - Add the glue for the auto generated x86 IRQ vector array.

    #

  - Add a generator for x86's IRQ vectors -> strings

  - Introduce stroul() (string -> number) methods for the strarray and
    strarrays classes, also strtoul_flags, allowing to go from both strings
    and or-ed strings to numbers, allowing things like:

    # perf trace -e syscalls:sys_enter_mmap --filter="flags==DENYWRITE|PRIVATE|FIXED" sleep 1
         0.000 sleep/22588 syscalls:sys_enter_mmap(addr: 0x7f42d2aa5000, len: 1363968, prot: READ|EXEC, flags: PRIVATE|FIXED|DENYWRITE, fd: 3, off: 0x22000)
         0.011 sleep/22588 syscalls:sys_enter_mmap(addr: 0x7f42d2bf2000, len: 311296, prot: READ, flags: PRIVATE|FIXED|DENYWRITE, fd: 3, off: 0x16f000)

    #

  Allowing to narrow down from the complete set of mmap calls for that workload:

    # perf trace -e syscalls:sys_enter_mmap sleep 1
         0.000 sleep/22695 syscalls:sys_enter_mmap(len: 134773, prot: READ, flags: PRIVATE, fd: 3)

         0.077 sleep/22695 syscalls:sys_enter_mmap(addr: 0x7fd240103000, len: 311296, prot: READ, flags: PRIVATE|FIXED|DENYWRITE, fd: 3, off: 0x16f000)

         0.095 sleep/22695 syscalls:sys_enter_mmap(addr: 0x7fd240156000, len: 14272, prot: READ|WRITE, flags: PRIVATE|FIXED|ANONYMOUS)
         0.339 sleep/22695 syscalls:sys_enter_mmap(len: 217750512, prot: READ, flags: PRIVATE, fd: 3)

  Works with all targets, so, for system wide, looking at who calls mmap with flags set to just "PRIVATE":

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

----------------------------------------------------------------
perf/core improvements and fixes:

perf trace:

  Arnaldo Carvalho de Melo:

  - Reuse the strace-like syscall_arg_fmt->scnprintf() beautification routines
    (convert integer arguments into strings, like open flags, etc) in tracepoint
    arguments.

    For now the type based scnprintf routines (pid_t, umode_t, etc) and the
    ones based in well known arg name based ("fd", etc) gets associated with
    tracepoint args of that type.

    A tracepoint only arg, "msr", for the msr:{write,read}_msr gets added as
    an initial step.

  - Introduce syscall_arg_fmt->strtoul() methods to be the reverse operation
    of ->scnprintf(), i.e. to go from a string to an integer.

  - Implement --filter, just like in 'perf record', that affects the tracepoint
    events specied thus far in the command line, use the ->strtoul() methods
    to allow strings in tables associated with beautifiers to the integers
    the in-kernel tracepoint (eBPF later) filters expect, e.g.:

     # perf trace --max-events 1 -e sched:*ipi --filter="cpu==1 || cpu==2"
      0.000 as/24630 sched:sched_wake_idle_without_ipi(cpu: 1)

  - Default to not using libtraceevent and its plugins for beautifying
    tracepoint arguments, since now we're reusing the strace-like beautifiers.
    Use --libtraceevent_print (using just --libtrace is unambiguous and can
    be used as a short hand) to go back to those beautifiers.

    This will help in the transition, as can be seen in some of the sched tracepoints
    that still need some work in the libbeauty based mode:

  - Make -v (verbose) mode be honoured for .perfconfig based trace.add_events,
    to help in diagnosing problems with building eBPF events (-e source.c).

  - When using eBPF syscall payload augmentation do not show strace-like
    syscalls when all the user specified was some tracepoint event, bringing
    the behaviour in line with that of when not using eBPF augmentation.

Intel PT:

  exported-sql-viewer GUI:

  Adrian Hunter:

  - Add LookupModel, HBoxLayout, VBoxLayout, global time range calculations
    so as to add a time chart by CPU.

perf script:

  Andi Kleen:

  - Allow --time (to specify a time span of interest) with --reltime

perf diff:

  Jin Yao:

  - Report noise for cycles diff, i.e. a histogram + stddev.
    (timestamps relative to start).

perf annotate:

  Arnaldo Carvalho de Melo:

  - Initialize env->cpuid when running in live mode (perf top), as it
    is used in some of the per arch annotation init routines.

samples bpf:

  Björn Töpel:

  - Fixup fallout of using tools/perf/perf-sys. from outside tools/perf.

Core:

  Ian Rogers:

  - Avoid 'sample_reg_masks' being const + weak, as this breaks with some
    compilers that constant-propagate from the weak symbol.

libperf:

  - First part of moving the perf_mmap class from tools/perf to libperf.

  - Propagate CFLAGS to libperf from the tools/perf Makefile.

Vendor events:

  John Garry:

  - Add entry in MAINTAINERS with reviewers for the for perf tool arm64
    pmu-events files.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

  perf parser: Remove needless include directives (2019-09-25 16:26:41 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf record:

  Stephane Eranian:

  - Fix priv level with branch sampling for paranoid=2, i.e. the kernel checks
    if perf_event_attr_attr.exclude_hv is set in addition to .exclude_kernel,
    so reset both to zero.

  Arnaldo Carvalho de Melo:

  - Don't warn about not being able to read kernel maps (kallsyms, etc) when
    kernel samples aren't being collected.

perf list:

  Kim Phillips:

  - Allow plurals for metric, metricgroup., i.e.:

    $ perf list metrics

    was showing nothing, which is very confusing, make it work like:

    $ perf stat metric

perf stat:

  Andi Kleen:

  - Free memory access/leaks detected via valgrind, related to metrics.

Libraries:

libperf:

  Jiri Olsa:

  - Move more stuff from tools/perf, this time a first stab at moving perf_mmap
    methods.

libtracevent:

  Steven Rostedt (VMware):

  - Round up in tep_print_event() time precision.

  Tzvetomir Stoyanov (VMware):

  - Man pages for event print and related and plugins APIs.

  - Move traceevent plugins in its own subdirectory.

Feature detection:

  Thomas Richter:

  - Add detection of java-11-openjdk-devel package, in addition to the older
    versions supported.

Architecture specific:

S/390:

  Thomas Richter (2):

  - Include JVMTI support for s390

Vendor events:

AMD:

  Kim Phillips:

  - Add L3 cache events for Family 17h.

  - Remove redundant '['.

PowerPC:

  Mamatha Inamdar:

  - Remove P8 HW events which are not supported.

Cleanups:

  Arnaldo Carvalho de Melo:

  - Remove needless headers, add needed ones, move things around to reduce the
    headers dependency tree, speeding up builds by not doing needless compiles
    when unrelated stuff gets changed.

  - Ditch unused code that was dragging headers.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

[GIT PULL] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo/Thomas,

	Please consider pulling,

Best regards,

- Arnaldo

Test results at the end of this message, as usual.

The following changes since commit 42880f726c66f13ae1d9ac9ce4c43abe64ecac84:

  perf/x86/intel: Support PEBS output to PT (2019-08-28 11:29:39 +0200)

are available in the Git repository at:

for you to fetch changes up to 301011ba622513cb41ced59973972204e0da2f71:

  tools lib traceevent: Remove unneeded qsort and uses memmove instead (2019-08-29 08:36:12 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf top:

  Namhyung Kim:

  - Decay all events in the evlist, we were decaying just the first event
    in a group.

  - Fix linking of histograms in different evsels in a event group with more
    than two events.

  With the two fixes above a command line such as:

    # perf top -e '{cycles,instructions,cache-misses,cache-references}

    Should work as expected, with four columns and with all of them being
    decayed over time, i.e. less weight is given for older samples.

perf record:

  Arnaldo Carvalho de Melo:

  - Fix collection of build-ids when using setns() to get into namespaces,
    which had been broken with the introduction of the extra thread to
    react to PERF_RECORD_BPF_EVENT, i.e. to collect extra info for BPF
    programs. We need to unshare(CLONE_FS) in that thread so that the
    main one can do the setns(CLONE_NEWNS) when collectingthe build-ids.
    Without that symbol resolution gets more difficult and potentially
    misresolves symbols.

core:

  Igor Lubashev:

  - Further alignment in permission checking via capabilities to how the
    kernel checks what tooling tries to do.

PowerPC:

  Naveen N. Rao:

  - Sync powerpc syscall.tbl, so that 'perf trace' gets the definitions
    for recent syscalls.

libperf:

  Jiri Olsa:

  - Move the rest of the PERF_RECORD_ metadata struct definitions so that
    we can use 'union perf_event'.

libtraceevent:

  Steven Rostedt (VMware):

  - Do not free tep->cmdlines in add_new_comm() on failure.

  - Remove unneeded qsort and uses memmove instead

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

  libperf: Fix alignment trap with xyarray contents in 'perf stat' (2019-08-22 17:16:57 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf c2c:

  Ravi Bangoria:

  - Fix report with offline cpus.

libperf:

  Gerald BAEZA:

  - Fix alignment trap with xyarray contents in 'perf stat', noticed on ARMv7.

  Jiri Olsa:

  - Move some more cpu_map and thread_map methods from tools/perf/util/ to libperf.

headers:

  Arnaldo Carvalho de Melo:

  - Do some house cleaning on the headers, removing needless includes in some places,
    providing forward declarations when those are the only thing needed, and fixing
    up the fallout from that for cases where we were using stuff and not adding the
    necessary headers. Should speed up the build and avoid needless rebuilds when
    something unrelated gets touched.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Yeah, we need to polish these kind of little details, pressing 'C' and
getting callchains enabled/disabled would be nice as well in 'perf top',
just thought about that :-)

  libperf: Fix arch include paths (2019-08-20 12:29:36 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

callchains:

   Alexey Budankov:

  - Allow collecting LBR together with DWARF callchains, for workloads
    where the userspace stack size collected is not big enough for
    pure DWARF based unwinding.

  - Dump the LBR call stack in 'perf report -D'.

perf top:

  Arnaldo Carvalho de Melo:

  - Show visual cue at start to state that the minimal set of samples
    are being collected prior to sorting/bucketizing/displaying.

CoreSight (ARM hardware tracing):

  Leo Yan:

  - Support sample flags 'insn' and 'insnlen'.

core:

  Adrian Hunter:

  - Add comment for 'idx' member in 'struct perf_sample_id.

tools headers:

  Arnaldo Carvalho de Melo:

  - Synchronize linux/bits.h, which required grabbing a copy of the kernel
    const.h headers and some changes in the ordering of header directories.

  - Sync x86's asm/cpufeatures.h with the with the kernel, no change in
    any of the tools.

libperf:

  Jiri Olsa:

  - Fix arch include paths.

libtraceevent:

  Steven Rostedt (VMware):

  - Fix "robust" test of do_generate_dynamic_list_file.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

  perf unwind: Remove unnecessary test (2019-08-16 12:30:14 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

report/script/trace/top:

  Arnaldo Carvalho de Melo:

  - Allow specifying marker events demarcating when to consider the other events,
    i.e. one now can state something like:

        # perf probe kernel_function
        # perf record -e cycles,probe:kernel_function

    And then, in 'perf script' or 'perf report' say:

        # perf report --switch-on=probe:kernel_function

    And then the cycles event samples will be considered only after we
    find the first probe:kernel_function event.

    There is also --switch-off=event, to make it stop considering events
    out of some window, say to avoid some winding down of a workload.

    The same can be done with the "live mode" tools: 'perf top' and 'perf trace'.

    There are examples in the cset comments showing how to use it with
    SDT events in things like 'systemtap', that have those tracepoint-like
    events for the start/end of passes, etc.

    Another example involves selecting scheduler events + entry/exit of
    a syscall, using the syscalls tracepoints, one can then see the
    scheduler events that take place while that syscall is being processed.

    In the future this should be possible in record/top/trace via eBPF
    where the perf tools would hook into the marker events and enable events
    put in place but not enabled when the on/off conditions are the desired
    ones, reducing the amount of events sampled, but this userspace only
    solution should be good enough for many scenarios.

perf vendor events intel:

  Haiyan Song:

  - Add Tremontx event file v1.02.

unwind:

  John Keeping:

  - Fix callchain unwinding when tid != pid, that was working only for the
    thread group leader.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

  perf ui: No need to set ui_browser to 1 twice (2019-08-14 11:00:00 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

Intel PT:

  Adrian Hunter:

  - Add PEBS via Intel PT support, the kernel bits went via PeterZ.

perf record:

  Alexander Shishkin:

  - Add an option to take an AUX snapshot on exit.

  Tan Xiaojun:

  - Support aarch64 random socket_id assignment, just like was fixed for S/390.

tools:

  Andy Shevchenko:

  - Keep list of tools in alphabetical order on 'make -C tools help'.

perf session:

  Arnaldo Carvalho de Melo:

  - Avoid infinite loop when seeing invalid header.size, reported by
    Vince Weaver using a perf.data fuzzer.

Documentation:

  Vince Weaver:

  - Clarify HEADER_SAMPLE_TOPOLOGY format in the perf.data spec.

perf config:

  Arnaldo Carvalho de Melo:

  - Honour $PERF_CONFIG env var to specify alternate .perfconfig.

perf test:

  Arnaldo Carvalho de Melo:

  - Disable ~/.perfconfig to get default output in 'perf trace' tests.

perf top:

  Arnaldo Carvalho de Melo:

  - Set display thread COMM to help with debugging.

  - Collapse and resort evsels in a group, so that we have output
    similar to 'perf report' when using event groups, i.e.

      perf top -e '{cycles,instructions}'

    Will have two columns, and the instructions one will work.

core:

  Igor Lubashev:

  - Detect if libcap development files are available so that we
    can use capabilities to match the checks made by the kernel instead
    of using plain (geteuid() == 0).

Intel:

  Haiyan Song:

  - Add Icelake V1.00 event file.

perf trace:

  Leo Yan:

  - Fix segmentation fault when access syscall info on arm64.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

for you to fetch changes up to 916c31fff946fae0e05862f9b2435fdb29fd5090:

  perf version: Fix segfault due to missing OPT_END() (2019-07-15 07:59:05 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf db-export:

  Adrian Hunter:

  - Improvements in how COMM details are exported to databases for
    post processing and use in the sql-viewer.py UI.

  - Export switch events to the database.

BPF:

  Arnaldo Carvalho de Melo:

  - Bump rlimit(MEMLOCK) for 'perf test bpf' and 'perf trace', just like
    selftests/bpf/bpf_rlimit.h do, which makes errors due to exhaustion of
    this limit, which are kinda cryptic (EPERM sometimes) less frequent.

perf version:
  Ravi Bangoria:

  - Fix segfault due to missing OPT_END(), noticed on PowerPC.

perf vendor events:

  Thomas Richter:

  - Add JSON files for IBM s/390 machine type 8561.

perf cs-etm (ARM):

  YueHaibing:

  - Fix two cases of error returns not bing done properly: Invalid ERR_PTR() use
    and loss of propagation error codes.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

The 'perf test bpf' test is about rlimit(MEMLOCK), bump it a to 128K from the
default 64K and it'll work. Next pull req will have auto-adjustment for 'perf
test' and 'perf trace', where BPF programs creating maps are also failing.

  perf intel-pt: Fix potential NULL pointer dereference found by the smatch tool (2019-07-09 10:13:28 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

Intel PT:

  Adrian Hunter:

  - Fix DROP VIEW power_events_view in the postgresql and sqlite export-db
    python scripts.

perf script:

  Song Liu:

  - Assume native_arch for pipe mode, fixing a segfault.

perf inject:

  Arnaldo Carvalho de Melo:

  - The tool->read() call may pass a NULL evsel, handle it.

core:

  Arnaldo Carvalho de Melo:

  - Move zalloc/zfree.c to tools/lib, further eroding tools/perf/util.[ch]

  - Use zfree() where applicable instead of open coded equivalent.

  - Add stdlib.h and some other headers to places where its needed and were
    getting via util.h, that doesn't need that anymore.

  - Use list_del_init() more thoroughly.

Miscellaneous:

  Leo Yan:

  - Fix use after free and potential NULL pointer derefs detected by the
    smatch tool in various places.

  Luke Mujica:

  - Remove a couple unused variables in the parse-events code.

  Numfor Mbiziwo-Tiapo:

  - Initialize variable to suppress memory sanitizer warning in the
    mmap-thread-lookup 'perf test' entry.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

The 'perf test bpf' test is about rlimit(MEMLOCK), bump it a to 128K from the
default 64K and it'll work. Next pull req will have auto-adjustment for 'perf
test' and 'perf trace', where BPF programs creating maps are also failing.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Investigating the failure for ubuntu:18.04-x-arm, doesn't look like something
introduced by this patchkit.

ubuntu:18.04-x-arm failure not yet resolved, doesn't seem related to
this patchkit nor the previous one.

[GIT PULL] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling,

Best regards,

- Arnaldo

Test results at the end of this message, as usual.

The following changes since commit fd7d55172d1e2e501e6da0a5c1de25f06612dc2e:

  perf/cgroups: Don't rotate events for cgroups unnecessarily (2019-06-24 19:30:04 +0200)

are available in the Git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-core-for-mingo-5.3-20190701

for you to fetch changes up to 06c642c0e9fceafd16b1a4c80d44b1c09e282215:

  perf jevents: Use nonlocal include statements in pmu-events.c (2019-07-01 22:50:42 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf annotate:

  Mao Han:

  - Add support for the csky processor architecture.

perf stat:

  Andi Kleen:

  - Fix metrics with --no-merge.

  - Don't merge events in the same PMU.

  - Fix group lookup for metric group.

Intel PT:

  Adrian Hunter:

  - Improve CBR (Core to Bus Ratio) packets support.

  - Fix thread stack return from kernel for kernel only case.

  - Export power and ptwrite events to sqlite and postgresql.

core libraries:

  Arnaldo Carvalho de Melo:

  - Find routines in tools/perf/util/ that have implementations in the kernel
    libraries (lib/*.c), such as strreplace(), strim(), skip_spaces() and reuse
    them after making a copy into tools/lib and tools/include/.

    This continues the effort of having tools/ code looking as much as possible
    like kernel source code, to help encourage people to work on both the kernel
    and in tools hosted in the kernel sources.

    That in turn will help moving stuff that uses those routines to
    tools/lib/perf/ where they will be made available for use in other tools.

    In the process ditch old cruft, remove unused variables and add missing
    include directives for headers providing things used in places that were
    building by sheer luck.

  Kyle Meyer:

  - Bump MAX_NR_CPUS and MAX_CACHES to get these tools to work on more machines.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Investigating the failure for ubuntu:18.04-x-arm, doesn't look like something
introduced by this patchkit.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

[GIT PULL] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling, I pulled tip/perf/urgent into
tip/pref/core, IIRC was just a fast forward at that point, yeap, just
did it again and it still is:

  $ git checkout -b t tip/perf/core
  Branch 't' set up to track remote branch 'perf/core' from 'tip'.
  Switched to a new branch 't'
  $ git merge tip/perf/urgent
  Updating d15d356887e7..c7a286577d75
  Fast-forward
  <SNIP>

         IIRC Jiri needs this for a pile of patches he submitted and
that I'll process next,

Best regards,

- Arnaldo

  perf stat: Support 'percore' event qualifier (2019-05-16 14:17:24 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf.data:

  Alexey Budankov:

  - Streaming compression of perf ring buffer into PERF_RECORD_COMPRESSED
    user space records, resulting in ~3-5x perf.data file size reduction
    on variety of tested workloads what saves storage space on larger
    server systems where perf.data size can easily reach several tens or
    even hundreds of GiBs, especially when profiling with DWARF-based
    stacks and tracing of context switches.

perf record:

  Arnaldo Carvalho de Melo

  - Improve -user-regs/intr-regs suggestions to overcome errors.

perf annotate:

  Jin Yao:

  - Remove hist__account_cycles() from callback, speeding up branch processing
    (perf record -b).

perf stat:

  - Add a 'percore' event qualifier, e.g.: -e cpu/event=0,umask=0x3,percore=1/,
    that sums up the event counts for both hardware threads in a core.

    We can already do this with --per-core, but it's often useful to do
    this together with other metrics that are collected per hardware thread.

    I.e. now its possible to do this per-event, and have it mixed with other
    events not aggregated by core.

core libraries:

  Donald Yandt:

  - Check for errors when doing fgets(/proc/version).

  Jiri Olsa:

  - Speed up report for perf compiled with linbunwind.

tools headers:

  Arnaldo Carvalho de Melo

  - Update memcpy_64.S, x86's kvm.h and pt_regs.h.

arm64:

  Florian Fainelli:

  - Map Brahma-B53 CPUID to cortex-a53 events.

  - Add Cortex-A57 and Cortex-A72 events.

csky:

  Mao Han:

  - Add DWARF register mappings for libdw, allowing --call-graph=dwarf to work
    on the C-SKY arch.

x86:

  Andi Kleen/Kan Liang:

  - Add support for recording and printing XMM registers, available, for
    instance, on Icelake.

  Kan Liang:

  - Add uncore_upi (Intel's "Ultra Path Interconnect" events) JSON support.
    UPI replaced the Intel QuickPath Interconnect (QPI) in Xeon Skylake-SP.

Intel PT:

  Adrian Hunter

  . Fix instructions sampling rate.

  . Timestamp fixes.

  . Improve exported-sql-viewer GUI, allowing, for instance, to copy'n'paste
    the trees, useful for e-mailing.

Documentation:

  Thomas Richter:

  - Add description for 'perf --debug stderr=1', which redirects stderr to stdout.

libtraceevent:

  Tzvetomir Stoyanov:

  - Add man pages for the various APIs.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

  The getname_flags related tests failing at the end (tests 65, 66 and 67) are
  being investigated, getname_flags() seems to have become just a tail call from
  getname(), something in this are changed and we're not anymore being able to
  add a probe at a suitable place to collect the just copied from userspace
  pathname.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
