  uprobes: Fix handle_swbp() vs. unregister() + register() race once more 
(2018-11-23 08:31:19 +0100)


perf/core improvements and fixes:

- Introduce 'perf record --aio' to use asynchronous IO trace writing in
  'perf record' disabled by default, i.e. one needs to explicitly use
  'perf record --aio' to use it, in which case the number of AIO aiocb
  structs will be one, specify 'perf record --aio=N' to ask for more,
  according to your needs, related to the number of processors in your
  machine. Reports about the effectiveness of this option are welcome
  so that we can decide on making it the default mode of operation. Read
  the respective patches commit logs for further information (Alexey Budankov)

- Add fallback routines to be used in places where we don't have the cpu mode
  (kernel/user space/hypervisor) and thus must first fallback lookups looking
  at all map trees when trying to resolve symbols (Adrian Hunter)

- Introduce 'perf top --kallsyms file' to match 'perf report --kallsyms', useful
  when dealing with BPF, where symbol resolution happens via kallsyms, not via
  the default vmlinux ELF symtabs (Arnaldo Carvalho de Melo)

- Fix CSV mode column output for non-cgroup events in 'perf stat' (Stephane 
Eranian)

- Fix 'perf stat' shadow stats for clock events. (Ravi Bangoria)

- Fix error with config term "pt=0", where we should just force "pt=1" and
  warn the user about the former being non-sensical (Adrian Hunter)

- Fix 'perf test' entry where we expect 'sleep' to come in a PERF_RECORD_COMM
  but instead we get 'coreutils' when sleep is provided by some versions of
  the 'coreutils' package (Adrian Hunter)

- Remove needless rb_tree extra indirection from map__find() (Eric 
Saint-Etienne)

- Add sanity check to libtraceevent's is_timestamp_in_us() (Tzvetomir Stoyanov)

- Use ERR_CAST instead of ERR_PTR(PTR_ERR()) (Wen Yang)

Test results:

XXX: Investigation on the watchpoint and breakpoint 'perf test' failures is
 underway, doesn't look like related to patches in this batch.

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.

Build and test stats at the end of the message.

The following changes since commit 41aad2a6d4fcdda8d73c9739daf7a9f3f49499d6:

  Merge tag 'perf-core-for-mingo-20160929' of 
git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core 
(2016-09-29 19:09:58 +0200)

  perf pmu-events: Add Skylake frontend MSR support (2016-10-03 21:52:01 -0300)


perf/core improvements and fixes:

- Allow vendors to provide JSON files describing PMU events, that then
  get parsed to generate C tables that are linked against perf, allowing
  the use of the names in their documentations, such as:

  # perf list l1d

  List of pre-defined events (to be used in -e):

  Cache:
l1d.replacement
 [L1D data line replacements]
l1d_pend_miss.fb_full
 [Cycles a demand request was blocked due to Fill Buffers 
inavailability]
l1d_pend_miss.pending
 [L1D miss oustandings duration in cycles]
l1d_pend_miss.pending_cycles
 [Cycles with L1D load Misses outstanding]
l1d_pend_miss.pending_cycles_any
 [Cycles with L1D load Misses outstanding from any thread on physical 
core]
l2_trans.l1d_wb
 [L1D writebacks that access L2 cache]

  Pipeline:
cycle_activity.cycles_l1d_miss
 [Cycles while L1 cache miss demand load is outstanding]
cycle_activity.cycles_l1d_pending
 [Cycles while L1 cache miss demand load is outstanding]
cycle_activity.stalls_l1d_miss
 [Execution stalls while L1 cache miss demand load is outstanding]
cycle_activity.stalls_l1d_pending
 [Execution stalls while L1 cache miss demand load is outstanding]

  The above example was done on a Broadwell based ThinkPad t450s after
  downloading and installing such JSON files which will be added to the
  tools/perf/pmu-events/ directory in a subsequent patchkit.

  Now one can use those names with -e/--event in all 'perf tools'.
  (Andi Kleen, Sukadev Bhattiprolu)

- Add a missing pointer dereference in 'perf probe' (Colin Ian King)

- Add support for building host programs to be used in generating files
  to be used in the build process, such as fixdep and jevents, fixing
  the usage of these features in a cross compilation setup (Jiri Olsa)

  perf symbols: Do not open device files (2016-09-20 16:20:21 -0300)


perf/core improvements and fixes:

User visible:

- Support event group view with hierarchy mode in 'perf top' and 'perf report'
  (Namhyung Kim)

  e.g.:

  $ perf record -e '{cycles,instructions}' make
  $ perf report --hierarchy --stdio
  ...
  #   Overhead  Command / Shared Object / Symbol
  # ..  ..

0.95%   0.00%[.] __strchr_sse2
0.89%   1.39%[.] __tsearch
0.76%   0.00%[.] strlen

- Fix the dwarf regs table for x86_64, adding a missing % to the "%di"
  register, noticed with a failing 'perf test bpf' (Arnaldo Carvalho de Melo)

- Fix handling of mmap parameters in the 'perf trace' beautifier in
  architectures that don't have the same mappings as x86_64 (Wang Nan)

- Handle hugetbl mappings in older systems running new kernels (Wang Nan)

- Resolve 'call' operands in 'annotate', that when using /proc/kcore
  were appearing just as hexadecimal addresses, to function names
  (Arnaldo Carvalho de Melo)

- Fix width computation for srcline sort entry (Jiri Olsa)

- Do not ignore call instruction with indirect target in 'annotate'
  (Ravi Bangoria)

- Handle MADV_FREE in the madvise 'trace' beautifier (Wang Nan)

- Fix build of 'perf trace' mman beautifier in !x86_64 (Wang Nan)

Infrastructure:

- Add infrastructure for PMU specific configuration, allowing to pass
  config variables directly to the kernel PMU driver, prefixing those
  variables with a '@', part of a larger series to support Coresight (Mathieu 
Poirier)

[GIT PULL 00/22] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

Please consider pulling,

- Arnaldo

The following changes since commit 3b364d7b587db0f0eeafde0f271e0698187de776:

  perf/core: Remove unused arguments from a bunch of functions (2016-02-17 
10:37:48 +0100)

are available in the git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git

for you to fetch changes up to 5b2ea6f2f6ac81a230e6cc68e1473e796a583f00:

  perf report: Check error during report__collapse_hists() (2016-02-19 19:17:50 
-0300)


perf/core improvements and fixes:

User visible:

- Add 'perf record' --all-user/--all-kernel options, so that one can tell
  that all the events in the command line should be restricted to the user
  or kernel levels (Jiri Olsa), i.e.:

perf record -e cycles:u,instructions:u

  is equivalent to:

perf record --all-user -e cycles,instructions

- Fix percentage update on key press, due to the buffering code
  (that creates hist_entries that will later be consumed) touching
  per hists state that is used by the display thread (Namhyung Kim)

- Bail out when event modifiers not supported by 'perf stat' are
  specified, i.e.: (Wang Nan)

  # perf stat -e cycles/no-inherit/ usleep 1
  event syntax error: 'cycles/no-inherit/'
   \___ 'no-inherit' is not usable in 'perf stat'
  # perf stat -e cycles/foo/ usleep 1
  event syntax error: 'cycles/foo/'
  \___ unknown term

  valid terms: config,config1,config2,name
  #

- Enable setting names for legacy cache, raw and numeric events, e.g: (Wang Nan)

  # perf record -e cycles -e 4:0x6530160/name=evtx,call-graph=fp/ -a sleep 1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 1.659 MB perf.data (844 samples) ]
  # perf evlist
  cycles
  evtx
  #

Miscelaneous/Infrastructure:

- Handled scaled == -1 case for counters in 'perf stat', fixing
  recent, only in perf/core, regression (Andi Kleen)

- Reference count the cpu and thread maps at set_maps(), fixing the
  'object code reading' 'perf test' entry when it was requesting a
  perf_event_attr.sample_freq > /proc/sys/kernel/perf_event_max_sample_rate
  (Arnaldo Carvalho de Melo)

- Improve perf_evlist__strerror_open() to provide hints for -EINVAL due
  to perf_event_attr.sample_freq > /proc/sys/kernel/perf_event_max_sample_rate
  (Arnaldo Carvalho de Melo)

- Add checks to various callchain and histogram routines (Namhyung Kim)

- Fix checking asprintf return value when parsing additional event config terms 
(Wang Nan)

[GIT PULL 00/22] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

Please consider pulling,

- Arnaldo

The following changes since commit 3b364d7b587db0f0eeafde0f271e0698187de776:

  perf/core: Remove unused arguments from a bunch of functions (2016-02-17 
10:37:48 +0100)

are available in the git repository at:

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

for you to fetch changes up to 5b2ea6f2f6ac81a230e6cc68e1473e796a583f00:

  perf report: Check error during report__collapse_hists() (2016-02-19 19:17:50 
-0300)


perf/core improvements and fixes:

User visible:

- Add 'perf record' --all-user/--all-kernel options, so that one can tell
  that all the events in the command line should be restricted to the user
  or kernel levels (Jiri Olsa), i.e.:

perf record -e cycles:u,instructions:u

  is equivalent to:

perf record --all-user -e cycles,instructions

- Fix percentage update on key press, due to the buffering code
  (that creates hist_entries that will later be consumed) touching
  per hists state that is used by the display thread (Namhyung Kim)

- Bail out when event modifiers not supported by 'perf stat' are
  specified, i.e.: (Wang Nan)

  # perf stat -e cycles/no-inherit/ usleep 1
  event syntax error: 'cycles/no-inherit/'
   \___ 'no-inherit' is not usable in 'perf stat'
  # perf stat -e cycles/foo/ usleep 1
  event syntax error: 'cycles/foo/'
  \___ unknown term

  valid terms: config,config1,config2,name
  #

- Enable setting names for legacy cache, raw and numeric events, e.g: (Wang Nan)

  # perf record -e cycles -e 4:0x6530160/name=evtx,call-graph=fp/ -a sleep 1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 1.659 MB perf.data (844 samples) ]
  # perf evlist
  cycles
  evtx
  #

Miscelaneous/Infrastructure:

- Handled scaled == -1 case for counters in 'perf stat', fixing
  recent, only in perf/core, regression (Andi Kleen)

- Reference count the cpu and thread maps at set_maps(), fixing the
  'object code reading' 'perf test' entry when it was requesting a
  perf_event_attr.sample_freq > /proc/sys/kernel/perf_event_max_sample_rate
  (Arnaldo Carvalho de Melo)

- Improve perf_evlist__strerror_open() to provide hints for -EINVAL due
  to perf_event_attr.sample_freq > /proc/sys/kernel/perf_event_max_sample_rate
  (Arnaldo Carvalho de Melo)

- Add checks to various callchain and histogram routines (Namhyung Kim)

- Fix checking asprintf return value when parsing additional event config terms 
(Wang Nan)
