With the OUTPUT variable set the libtraceevent.a file is wrongly built
in the source directory:
+ make -d OUTPUT=/.../.build/perf-user/ DESTDIR=/.../.install/perf-user/
...
Considering target file `../lib/traceevent//libtraceevent.a'.
File `../lib/traceevent//libtraceevent.a' does not exist.
Finished prerequisites of target file `../lib/traceevent//libtraceevent.a'.
Must remake target `../lib/traceevent//libtraceevent.a'.
Invoking recipe from Makefile:837 to update target `../lib/traceevent//libtraceevent.a'.
Putting child 0x703850 (../lib/traceevent//libtraceevent.a) PID 8365 on the chain.
Live child 0x703850 (../lib/traceevent//libtraceevent.a) PID 8365

This patch fixes this.
Note: Though this should already work with O=$outputdir we better use
the OUTPUT variable directly.

perf record fails on 32 bit with:
invalid or unsupported event: 'r40000F7E0'
Fixing this by parsing 64 bit num values.

---------------
Events can optionally have a modifer by appending a colon and one or
-more modifiers. Modifiers allow the user to restrict when events are

-Additional modifiers are 'G' for guest counting (in KVM guests) and 'H'

+more modifiers. Modifiers allow the user to restrict the events to be
+counted. The following modifiers exist:
+
+ u - user-space counting
+ k - kernel counting
+ h - hypervisor counting
+ G - guest counting (in KVM guests)
+ H - host counting (not in KVM guests)
+ p - precise level
The 'p' modifier can be used for specifying how precise the instruction
-address should be. The 'p' modifier is currently only implemented for
-Intel PEBS and can be specified multiple times:
- 0 - SAMPLE_IP can have arbitrary skid
- 1 - SAMPLE_IP must have constant skid
- 2 - SAMPLE_IP requested to have 0 skid
- 3 - SAMPLE_IP must have 0 skid
+address should be. The 'p' modifier can be specified multiple times:
+
+ 0 - SAMPLE_IP can have arbitrary skid
+ 1 - SAMPLE_IP must have constant skid
+ 2 - SAMPLE_IP requested to have 0 skid
+ 3 - SAMPLE_IP must have 0 skid
+
+For Intel systems precise event sampling is implemented with PEBS
+which supports up to precise-level 2.
+
+On AMD systems it is implemented using IBS (up to precise-level 2).
+The precise modifier works with event types 0x76 (cpu-cycles, CPU
+clocks not halted) and 0xC1 (micro-ops retired). Both events map to
+IBS execution sampling (IBS op) with the IBS Op Counter Control bit
+(IbsOpCntCtl) set respectively (see AMD64 Architecture Programmer’s
+Manual Volume 2: System Programming, 13.3 Instruction-Based

From: Feng Tang <feng.tang@intel.com>
This patch just follows Robert Richter's idea and the commit 37a058ea0
"perf script: Add generic perl handler to process events"
to similarly add a python handler for general events other than tracepoints.
For non-tracepoint events, this patch will try to find a function named
"process_event" in the python script, and pass the event attribute,
perf_sample, raw_data in format of raw string. And the python script can
use "struct" module's unpack function to disasemble the needed info and process.

From: Feng Tang <feng.tang@intel.com>
Both perl and python script start processing events other than trace
points, and it's useful to pass the resolved symbol and the dso info to
the event handler in script for better analysis and statistics.
Struct thread is already a member of struct addr_location, using
addr_location will keep the thread info, while providing additional
symbol and dso info if exist, so that the script itself doesn't need to
bother to do the symbol resolving and dso searching work.

Also as suggested by Arnaldo, pack all these parameters to a dictionary,
which is more expandable for adding new parameters while keeping the
compatibility for old scripts.

This library defines several class types for perf events which could
help to better analyze the event samples. Currently there are just a few
classes, PerfEvent is the base class for all perf events, PebsEvent is
a HW base Intel x86 PEBS event, and user could add more SW/HW event
classes based on requriements.

From: Feng Tang <feng.tang@intel.com>
Currently only trace point events are supported in perf/python script,
the first 3 patches of this serie add the support for all types of
events. This script is just a simple sample to show how to gather the
basic information of the events and analyze them.
This script will create one object for each event sample and insert them
into a table in a database, then leverage the simple SQL commands to
sort/group them. User can modify or write their brand new functions
according to their specific requirment.
Here is the sample of how to use the script:
$ perf record -a tree
$ perf script -s process_event.py
There is 100 records in gen_events table
Statistics about the general events grouped by thread/symbol/dso:

Please edit the script name to event_analyzing_sample.py at least to
prevent future confusion. For other issues, please see my review
comments on Feng's original posts. (They can be incremental.)

perf bpf: Fix NULL return handling in bpf__prepare_load() (2018-05-16 10:01:55 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
- Add '-e intel_pt//u' test to the 'parse-events' 'perf test' entry,
to help avoiding regressions in the events parser such as one
that caused a revert in v4.17-rc (Arnaldo Carvalho de Melo)
- Fix NULL return handling in bpf__prepare_load() (YueHaibing)
- Warn about 'perf buildid-cache --purge-all' failures (Ravi Bangoria)
- Add infrastructure to help in writing eBPF C programs to be used
with '-e name.c' type events in tools such as 'record' and 'trace',
with headers for common constructs and an examples directory that
will get populated as we add more such helpers and the 'perf bpf'
branch that Jiri Olsa has been working on (Arnaldo Carvalho de Melo)
- Handle uncore event aliases in small groups properly (Kan Liang)
- Use the "_stest" symbol to identify the kernel map when loading kcore (Adrian Hunter)

Test results:
The first ones are container (docker) 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.

Hi Ingo,
Please consider pulling, more to come as I go thru Adrian's x86
PTI series and the C++ support improvements to 'perf probe', from
Holger,
Best Regards,

perf bpf: Fix NULL return handling in bpf__prepare_load() (2018-05-16 10:01:55 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
- Add '-e intel_pt//u' test to the 'parse-events' 'perf test' entry,
to help avoiding regressions in the events parser such as one
that caused a revert in v4.17-rc (Arnaldo Carvalho de Melo)
- Fix NULL return handling in bpf__prepare_load() (YueHaibing)
- Warn about 'perf buildid-cache --purge-all' failures (Ravi Bangoria)
- Add infrastructure to help in writing eBPF C programs to be used
with '-e name.c' type events in tools such as 'record' and 'trace',
with headers for common constructs and an examples directory that
will get populated as we add more such helpers and the 'perf bpf'
branch that Jiri Olsa has been working on (Arnaldo Carvalho de Melo)
- Handle uncore event aliases in small groups properly (Kan Liang)
- Use the "_stest" symbol to identify the kernel map when loading kcore (Adrian Hunter)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
----------------------------------------------------------------
Adrian Hunter (1):
perf tools: Use the "_stest" symbol to identify the kernel map when loading kcore
Arnaldo Carvalho de Melo (7):

Test results:
The first ones are container (docker) 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.

Hi Ingo,
There are some 'perf test' and container failures, but those
don't seem to have been introduced by patches in this series and are
being investigated.
Please consider pulling,

Test results:
The first ones are container (docker) based builds of tools/perf with and
without libelf support. Where clang is available, it is also used to build
perf with/without libelf.
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.

Test results:
The first ones are container (docker) based builds of tools/perf with and
without libelf support, objtool where it is supported and samples/bpf/, ditto.
Where clang is available, it is also used to build perf with/without libelf.
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.

perf/core improvements and fixes:
Fixes:
- Fix concat_probe_trace_events() in 'perf probe', it should dereference a
pointer, not test its value (Ravi Bangoria)
User visible:
- Handle partial AUX records, checking if 'kvm_intel.ko' is loaded and
if its 'vmm_exclusive' parameter is set to 0, suggesting tweaking
it to reduce gaps (Alexander Shishkin)
Infrastructure:
- Sync the kvm.h, cpufeatures.h and perf_event.h tools/ headers copies
with the kernel (Arnaldo Carvalho de Melo, Alexander Shishkin)
- 'perf lock' subcommands should include common options, using
OPT_PARENT() (Changbin Du)
- Ditto for 'perf timechart' (Arnaldo Carvalho de Melo)

Hi Ingo,
Please consider pulling,
- Arnaldo
Build news:
Now the 16.04-x-armhf and 16.04-x-powerpc64 cross build docker images have libz
and libelf cross built from sources, so that we can cover cross build testing
more of the codebase.
In those images objtool is not built, as checking powerpc and arm binaries is
not supported, so trying to build it will end up in linker errors.

Yeah, I noticed that, that is a compat one (the non-compat ones are
already in sync), which is something 'perf trace' needs to support but
can't right now due to raw_syscalls:sys_{enter,exit} limitations, so not
that important right now, will fix it anyway to remove the warning,
Thanks!

So, here is a new pull req, removing the following patch, due to that
segfault you noticed while testing 'perf top' on an ubuntu system:
> He Kuang (2):
> perf tools: Find vdso supporting cross-platform analysis
The new tag is perf-core-for-mingo-20160520.
Kuang, Ingo proposed the patch below to fix the problem he noticed
(notice the 'dso && ' part, as __dsos__find() may return NULL), but he
had several other issues with code touched by this patch, I'll try to
address those, please check the patch below and resubmit.

Hi Ingo,
Please consider pulling, this is on top of my previous pull
request (perf-core-for-mingo-20160516).
- Arnaldo
The following changes since commit a29d5c9b8167dbc21a7ca8c0302e3799f9063b4e:
perf tools: Separate accounting of contexts and real addresses in a stack trace (2016-05-16 23:11:54 -0300)

perf tools: Set buildid dir under symfs when --symfs is provided (2016-05-19 19:04:36 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- We should not use the current value of the kernel.perf_event_max_stack as the
default value for --max-stack in tools that can process perf.data files, they
will only match if that sysctl wasn't changed from its default value at the
time the perf.data file was recorded, fix it.
This fixes a bug where a 'perf record -a --call-graph dwarf ; perf report'
produces a glibc invalid free backtrace (Arnaldo Carvalho de Melo)
- Provide a better warning when running 'perf trace' on a system where the
kernel.kptr_restrict is set to 1, similar to the one produced by 'perf record',
noticed on ubuntu 16.04 where this is the default kptr_restrict setting.
(Arnaldo Carvalho de Melo)
- Fix ordering of instructions in the annotation code, noticed when annotating
ARM binaries, now that table is auto-ordered at first use, to avoid more such
problems (Chris Ryder)
- Fix searching the vdso image to support cross-platform analysis (He Kuang)
- Set buildid dir under symfs when --symfs is provided (He Kuang)
- Fix the 'exit_group()' syscall output in 'perf trace' (Arnaldo Carvalho de Melo)
- Only auto set call-graph to "dwarf" in 'perf trace' when syscalls are being
traced (Arnaldo Carvalho de Melo)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
----------------------------------------------------------------
Arnaldo Carvalho de Melo (7):
perf machine: Do not bail out if not managing to read ref reloc symbol
perf trace: Warn when trying to resolve kernel addresses with kptr_restrict=1
perf top: Use machine->kptr_restrict_warned
perf trace: Fix exit_group() formatting
perf callchain: Stop validating callchains by the max_stack sysctl
perf tools: Fix usage of max_stack sysctl
perf trace: Only auto set call-graph to "dwarf" when syscalls are being traced

perf trace: Move futex_op beautifier to tools/perf/trace/beauty/ (2016-05-06 13:00:59 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Fix ordering of kernel/user entries in 'caller' mode, where the kernel and
user parts were being correctly inverted but kept in place wrt each other,
i.e. 'callee' (k1, k2, u3, u4) became 'caller' (k2, k1, u4, u3) when it
should be 'caller' (u4, u3, k2, k1) (Chris Phlipot)
- In 'perf trace' don't print the raw arg syscall args for a syscall that has
no arguments, like gettid(). This was happening because just checking if
the syscall args list is NULL may mean that there are no args (e.g.: gettid)
or that there is no tracepoint info (e.g.: clone) (Arnaldo Carvalho de Melo)
- Add extra output of counter values with 'perf stat -vv' (Andi Kleen)
Infrastructure:
- Expose callchain db export via the python API (Chris Phlipot)
Code reorganization:
- Move some more syscall arg beautifiers from the 'perf trace' main file to
separate files in tools/perf/trace/beauty/, to reduce the main file line
count (Arnaldo Carvalho de Melo)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
----------------------------------------------------------------
Andi Kleen (1):
perf stat: Add extra output of counter values with -vv
Arnaldo Carvalho de Melo (4):

perf trace: Move signum beautifier to tools/perf/trace/beauty/
perf trace: Move open_flags beautifier to tools/perf/trace/beauty/
perf trace: Move futex_op beautifier to tools/perf/trace/beauty/
Chris Phlipot (6):

perf tools: Refactor code to move call path handling out of thread-stack
perf script: Enable db export to output sampled callchains
perf script: Add call path id to exported sample in db export

Hi Ingo,
Please consider pulling, this is on top of my previously submitted
acme/perf/urgent, so that we can test Andi's udis86 work on 'perf script'.
This is now test built in several more docker images, including
minimal feature cross-compiler builds ones:

#
Those x-arch cross docker images already allow me to avoid introducing
bugs like the powerpc one Sukadev spotted.
I need to figure out how to install more devel packages for things like
libelf-devel:arch in debian/ubuntu, I almost got there with 'dpkg
--add-architecture arch', but I still need to figure out how to find the list
of multilib enabled devel packages to allow me to have devel packages for other
arches than the native one...

Ok, I inserted Jiri's patch fixing the problem just before the commit
(fa184776ac27) that triggers it, so that we don't break bisection for
human-readable numbers in 'perf stat'.
Its all in a new signed tag, that combines the two outstanding ones
(perf-core-for-mingo-20160229 + perf-core-for-mingo-20160302), please
consider pulling.

yea, it used the pmu parsing which screwes locales,
following patch fixed that for me..

Hm, there's a 'perf stat' regression that I can see:
Before:
triton:~/tip> perf stat -a sleep 1
Performance counter stats for 'system wide':
11990.023100 task-clock (msec) # 11.981 CPUs utilized
8,802 context-switches # 0.734 K/sec
543 cpu-migrations # 0.045 K/sec
97,375 page-faults # 0.008 M/sec
9,854,385,894 cycles # 0.822 GHz
15,274,841,152 stalled-cycles-frontend # 155.01% frontend cycles idle
<not supported> stalled-cycles-backend
9,634,486,137 instructions # 0.98 insn per cycle
# 1.59 stalled cycles per insn
1,818,488,088 branches # 151.667 M/sec
46,365,120 branch-misses # 2.55% of all branches
1.000741599 seconds time elapsed
After:
triton:~/tip> perf stat -a sleep 1
Performance counter stats for 'system wide':
11989.280397 task-clock (msec) # 11.981 CPUs utilized
1299 context-switches # 0.108 K/sec
6 cpu-migrations # 0.001 K/sec
70 page-faults # 0.006 K/sec
127008602 cycles # 0.011 GHz
279538533 stalled-cycles-frontend # 220.09% frontend cycles idle
119213269 instructions # 0.94 insn per cycle
# 2.34 stalled cycles per insn
24166678 branches # 2.016 M/sec
505681 branch-misses # 2.09% of all branches
1.000684278 seconds time elapsed
... see how the numbers became human-unreadable, losing the big-number separator?
I suspect it's due to the following commit:
fa184776ac27 perf stat: Check existence of frontend/backed stalled cycles
Thanks,
Ingo

perf tools: Fallback to srcdir/Documentation/tips.txt (2016-01-12 12:42:08 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible new features:
- Add --buildid-all option to 'perf record' to avoid processing
samples, just collecting build-ids for _all_ the DSOs that appears
in PERF_RECORD_MMAP records (Namhyung Kim)
- Add some more usage tips to appear in the hists browser
(top & report) (Namhyung Kim, Andi Kleen)
- Fix mmap2 event allocation in synthesize code, where we were
allocating space just for PERF_RECORD_MMAP, the older variant,
which could lead to corner case problems (Wang Nan)
Developer stuff:
- Make list.h self-sufficient, removing one more reference to
kernel headers that lead to recent breakage when some rculist
change was made in the kernel sources. (Josh Poimboeuf)
Add missing NORETURN define for parse-options.h in
tools/lib/subcmd (Josh Poimboeuf)
- Fallback to srcdir/Documentation/ when not finding tips.txt
elsewhere (Namhyung Kim)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

Jiri Olsa (1):
perf stat: Fix recort_usage typo
Josh Poimboeuf (3):

entries (Arnaldo Carvalho de Melo)
- Inform the user about objdump failures in 'perf annotate' (Andi Kleen)
Infrastructure:
- Improve the LLVM 'perf test' entry, introduce new ones for
BPF and kbuild to check the environment used by clang to
compile .c scriptlets (Wang Nan)
