  perf probe: Add --cache option to cache the probe definitions (2016-06-15 14:34:42 -0300)

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

User visible:

- Add --ldlat option to 'perf mem' to specify load latency for loads
  event (e.g. cpu/mem-loads/ ) (Jiri Olsa)

Build fixes:

- Fix libunwind related compile error for static cross build (He Kuang)

Infrastructure:

- UI refactorings to support headers with multiple lines, non-evsel
  hists browsers, toggle showing callchains, etc (Jiri Olsa)

- More prep work for caching probe definitions, paving the way
  for supporting SDT (Statically Defined Traces) userspace probes (Masami Hiramatsu)

- Handle NULL at perf_config_set__delete() (Taeung Song)

perf_config_set__delete() purge and free the config set that contains
all config key-value pairs.  But if the config set (i.e. 'set' variable
at the function) is NULL, this is wrong so handle it.

From: Masami Hiramatsu <mhiramat@kernel.org>

Fix rm_rf() to handle non-regular files correctly. This fix includes two
changes;

 - Fix to use lstat(3) instead of stat(3) since if the target
   file is a symbolic link, rm_rf() should unlink the symbolic
   link itself, not the file which pointed by the symlink.
 - Fix to unlink non-regular files (except for directory),
   including symlink.

Even though the first one fixes to stat symlink itself, without second
fix, it still failed because the symlink is not a regular file.

From: Masami Hiramatsu <mhiramat@kernel.org>

Uncomment and export synthesize_perf_probe_point() which had once
introduced but has been disabled for a long time. This renews the code
and re-enable it.

This is because the remote libunwind library detected is not appended to
EXTLIBS variable, which will be included between 'start-group' and
'end-group' when linking.

The existing variable LIBUNWIND_LIBS is assigned to libs for local
unwind, this patch introduces a new variable EXTLIBS_LIBUNWIND for
storing remote libunwind libraries instead.

Adding --ldlat option to specify desired latency for loads event.

Specify 50 as loads event latency:

  $ perf mem record -e ldlat-loads -v --ldlat 50 true
  calling: record -W -d -e cpu/mem-loads,ldlat=50/P true

It will be useful for future changes that enhance headers with multiple
lines and span columns, which don't affect hierarchy headers.

Replacing perf_evsel arg perf_hpp_fmt's header callback with hists

None of the actual callbacks actually use evsel object, also this will
be helpful in future for non evsel related hist browsers.

From: Masami Hiramatsu <mhiramat@kernel.org>

Introduce perf_cache object and interfaces to create, add entries,
commit, and delete the object.

perf_cache represents a file for the cached "perf probe" definitions on
one binary file or vmlinux which has its own build id. The probe cache
file is located under the build-id cache directory of the target binary,
as below;

  <perf-debug-dir>/.build-id/<BU>/<ILDID>/probe

Hi Ingo,

	A bit of trivia info is now automatically shown in the container
builds, the gcc version used to build the tools, that gets changed as
the distros update gcc and as I update the container build images :-)

	Please consider pulling,

- Arnaldo

  perf srcline: Show correct function name for srcline of callchains (2017-11-01 11:44:38 -0300)

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

- Beautify the 'kcmp' and 'prctl' syscall arguments in 'perf trace'
  (Arnaldo Carvalho de Melo)

- Implement a way to print formatted output to per-event files in 'perf script'
  to facilitate generate flamegraphs, elliminating the need to write scripts to
  do that separation (yuzhoujian, Arnaldo Carvalho de Melo)

  Make 'perf stat --per-thread' update shadow stats to show metrics (Jiri Olsa)

- Fix double mapping al->addr in callchain processing for children without self
  period (Namhyung Kim)

- Fix memory leak in addr2inlines() when libbfd is not used (Namhyung Kim)

- Show correct function name for srcline of callchains when libbfd is not used
  (Namhyung Kim)

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.

  perf test shell: Add uprobes + backtrace ping test (2017-08-11 16:18:49 -0300)

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

Infrastructure:

- Do not consider empty files as valid srclines (Milian Wolff)

- Fix wrong size in perf_record_mmap for last kernel module,
  which resulted in erroneous symbol resolution in at least s390x (Thomas Richter)

- Add missing newline to expr parser error messages (Andi Kleen)

- Fix saved values rbtree lookup in 'perf stat' (Andi Kleen)

- Add support for shell based tests in 'perf test', add a few that
  run 'perf probe', 'perf trace', using kprobes, uprobes to check
  the output of those tools and the effects on the system, checking,
  for instance, DWARF backtraces from uprobes (Arnaldo Carvalho de Melo)

Arch specific:

- Add ppc64le to audit uname list in the python scripting support (Naveen N. Rao)

- Update POWER9 vendor events tables (Sukadev Bhattiprolu)

- Fix module symbol adjustment for s390x (Thomas Richter)

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.

The 'perf test'  also runs shell scripts exercising the tools, checking
if they affect the system in certain ways, like setting up kprobes and
uprobes, request callchains for well known programs and check that they
are the expected ones, see if 'perf trace' beautifies system call
arguments correctly, etc.

Additionally, a new set of tests, script based, runs the tools in a live system,
setting probes in place that then gets used by 'perf trace', with its output
compared against expected results.

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.

  kprobes: Convert kprobe_exceptions_notify to use NOKPROBE_SYMBOL (2017-03-14 15:17:40 -0300)

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

New features:

- Add PERF_RECORD_NAMESPACES so that the kernel can record information
  required to associate samples to namespaces, helping in container
  problem characterization.

  Now the 'perf record has a --namespace' option to ask for such info,
  and when present, it can be used, initially, via a new sort order,
  'cgroup_id', allowing histogram entry bucketization by a (device, inode)
  based cgroup identifier (Hari Bathini)

- Add --next option to 'perf sched timehist', showing what is the next
  thread to run (Brendan Gregg)

Fixes:

- Fix segfault with basic block 'cycles' sort dimension (Changbin Du)

- Add c2c to command-list.txt, making it appear in the 'perf help'
  output (Changbin Du)

- Fix zeroing of 'abs_path' variable in the perf hists browser switch
  file code (Changbin Du)

- Hide tips messages when -q/--quiet is given to 'perf report' (Namhyung Kim)

Infrastructure:

- Use ref_reloc_sym + offset to setup kretprobes (Naveen Rao)

- Ignore generated files pmu-events/{jevents,pmu-events.c} for git (Changbin Du)

Documentation:

- Document +field style argument support for --field option (Changbin Du)

- Clarify 'perf c2c --stats' help message (Namhyung Kim)

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 annotate: AArch64 support (2016-12-01 13:03:19 -0300)

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

New features:

- Support AArch64 in the 'annotate' code, native/local and
  cross-arch/remote (Kim Phillips)

- Allow considering just events in a given time interval, via the
  '--time start.s.ms,end.s.ms' command line, added to 'perf kmem',
  'perf report', 'perf sched timehist' and 'perf script' (David Ahern)

- Add option to stop printing a callchain at one of a given group of
  symbol names (David Ahern)

- Handle cpu migration events in 'perf sched timehist' (David Ahern)

- Track memory freed in 'perf kmem stat' (David Ahern)

Infrastructure:

- Initial support (and perf test entry) for tooling hooks, starting with
  'record_start' and 'record_end', that will have as its initial user the
  eBPF infrastructure, where perf_ prefixed functions will be JITed and
  run when such hooks are called (Wang Nan)

- Remove redundant "test" and similar strings from 'perf test' descriptions
  (Arnaldo Carvalho de Melo)

- libbpf assorted improvements (Wang Nan)

The following changes since commit 36e674a05164cdbb9d4a5b1b0b279fabae6c13bd:

  Merge tag 'perf-core-for-mingo-20160823' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2016-08-24 11:08:10 +0200)

  perf probe: Move dwarf specific functions to dwarf-aux.c (2016-09-01 12:42:26 -0300)

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

User visible:

- Support generating cross arch probes, i.e. if you specify a vmlinux
  file for different arch than the one in the host machine,

	 $ perf probe --definition function_name args

  will generate the probe definition string needed to append to the
  target machine /sys/kernel/debug/tracing/kprobes_events file, using
  scripting (Masami Hiramatsu).

- Make 'perf probe' skip the function prologue in uprobes if program
  compiled without optimization, using the same strategy as gdb and
  systemtap uses, fixing a bug where:

	$ perf probe -x ./test 'foo i'

  When 'foo(42)' was used on the "./test" executable would produce i=0
  instead of the expected i=42 (Ravi Bangoria)

- Demangle symbols for synthesized @plt entries too (Millian Wolff)

Documentation:

- Show default report configuration in 'perf config' example
  and docs (Millian Wolff)

Infrastructure:

- Make 'perf test vmlinux' tolerate the symbol aliasing pruning done when
  loading kallsyms and vmlinux (Arnaldo Carvalho de Melo)

- Improve output of 'perf test vmlinux' test, to help identify on the verbose
  output which lines are warning and which are errors (Arnaldo Carvalho de Melo)

- Prep work to stop having to pass symbol_filter_t to lots of functions,
  simplifying symtab loading routines (Arnaldo Carvalho de Melo)

- Honor symbol_conf.allow_aliases when loading kallsyms as well, it was using
  it only when loading vmlinux files (Arnaldo Carvalho de Melo)

- Fixup symbol->end before doing alias pruning when loading symbol tables
  (Arnaldo Carvalho de Melo)

- Fix error handling of lzma kernel module decompression (Shawn Lin)

Ingo, if you haven't pulled this one, please pull instead
perf-core-for-mingo-20160408, which has the same tag text and contents +
a Tested-by tag from Milian for the unwind thread one and a bisection
fix one liner for the syscall_tbl generation from Wang,

  Merge tag 'perf-core-for-mingo-20160401' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2016-04-06 08:46:23 +0200)

  perf symbols: Adjust symbol for shared objects (2016-04-07 17:17:01 -0300)

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

User visible:

- Beautify more syscall arguments in 'perf trace', using the type column in
  tracepoint /format fields to attach, for instance, a pid_t resolver to the
  thread COMM, also attach a mode_t beautifier in the same fashion
  (Arnaldo Carvalho de Melo)

- Build the syscall table id <-> name resolver using the same .tbl file
  used in the kernel to generate headers, to avoid the delay in getting
  new syscalls supported in the audit-libs external dependency, done so
  far only for x86_64 (Arnaldo Carvalho de Melo)

- Improve the documentation of event specifications (Andi Kleen)

- Process update events in 'perf script', fixing up this use case:

    # perf stat -a -I 1000 -e cycles record | perf script -s script.py

- Shared object symbol adjustment fixes, fixing symbol resolution in
  Android (Wang Nan)

Infrastructure:

- Add dedicated unwind addr_space member into thread struct, to allow
  tools to use thread->priv, noticed while working on having callchains
  in 'perf trace' (Jiri Olsa)

Build fixes:

- Fix the build in Ubuntu 12.04 (Arnaldo Carvalho de Melo, Vinson Lee)

  perf jit: add source line info support (2016-02-05 12:33:09 -0300)

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

User visible fixes:

- Handle spaces in file names obtained from /proc/pid/maps (Marcin Ślusarz)

New features:

- Improved support for java, using the JVMTI agent library to do jitdumps
  that then will be inserted in synthesized PERF_RECORD_MMAP2 events via
  'perf inject' pointed to synthesized ELF files stored in ~/.debug and
  keyed with build-ids, to allow symbol resolution and even annotation with
  source line info, see the changeset comments to see how to use it (Stephane Eranian)

Documentation:

- Document mmore variables in the 'perf config' man page (Taeung Song)

Infrastructure:

- Improve a bit the 'make -C tools/perf build-test' output (Arnaldo Carvalho de Melo)

- Do 'build-test' in parallell, using 'make -j' (Arnaldo Carvalho de Melo)

- Fix handling of 'clean' in multi-target make invokations for parallell builds (Jiri Olsa)

Hi Ingo,

        Please consider pulling, it is the pull req from yesterday, minus a patch
that introduced a problem, plus a fex fixes.

        I am investigating a problem I noticed for another patch that is upstream
and after that will get back to the removed patch from yesterday's batch,

- Arnaldo
