perf evlist: Fix typo in deliver_sample() (2017-01-17 11:36:45 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
New feature:
- Account thread wait time (off cpu time) separately: sleep, iowait and
preempt, based on the prev_state of the last event, show the breakdown
when using "perf sched timehist --state" (Namhyumg Kim)
Infrastructure:
- Factor out pmu scale conversion code (Andi Kleen)
- Remove unnecessary feature-dwarf warning (David Carrillo-Cisneros)
- Add missing member name in OPT_() macros (Soramichi AKIYAMA)
- Move variables referenced in libperf.a object files from perf's main()
file, so that other tools can use libperf.a with a different main()
(Soramichi AKIYAMA)
Documentation:
- Fix 'perf script' man page about --dump-raw-trace option (Michael Petlan)
- Also allow forcing reading of non-root owned files by root in 'perf
script' (Yannick Brosseau)

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.
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.

This patch adds missing member names to struct initializations.
Although in C99 for struct S {int x, int y} two init codes struct S s =
{.x = (a), (b)} and struct S s = {.x = (a), .y = (b)} are the same, it
is better to explicitly write .y (.argh in this patch) for readability
and robustness against language/compiler evolutions.

In 2059fc7a5a9e ("perf symbols: Allow forcing reading of non-root owned

This add the same behavior for perf script.

The --state option is to show task state when switched out. The state
is printed as a single character like in the /proc but I added 'I' for
idle state rather than 'R'.

From: Soramichi AKIYAMA <akiyama@m.soramichi.jp>
The use_browser and perf_version_string variables are both declared in
perf.c but they are also referenced by other functions of libperf.a.
Therefore a user linking an own main() with libperf.a must declare those
two variables in their files even if the files never use the browser or
the version information.
This patch fixes this issue by moving use_browser and
perf_version_string out of perf.c to some other files.

perf test shell: Replace '|&' with '2>&1 |' to work with more shells (2017-08-16 16:23:26 -0300)
----------------------------------------------------------------
perf core improvements and fixes:
New features:
- Support exporting Intel PT data to sqlite3 with python perf scripts,
this is in addition to the postgresql support that was already there (Adrian Hunter)
Infrastructure:
- Handle perf tool builds with less features in perf shell tests, such
as those with NO_LIBDWARF=1 or even without 'perf probe' (Arnaldo Carvalho de Melo)
- Replace '|&' with '2>&1 |' to work with more shells in the just
introduced perf test shell harness (Kim Phillips)
Architecture related fixes:
- Fix endianness problem when loading parameters in the BPF prologue
generated by perf, noticed using 'perf test BPF' in s390x systems (Wang Nan, 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.

Test results at the end of this message, as usual.
The following changes since commit fd7647979a3948dae4fc6f25dbbdf9ba269bed78:

perf config: Refactor a duplicated code for obtaining config file name (2017-05-02 18:23:12 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
Fixes:
- Support setting probes in versioned user space symbols, such as
pthread_create@@GLIBC_2.1, picking the default one, more work
needed to make it possible to set it on the other versions, as
the 'perf probe' syntax already uses @ for other purposes.
(Paul Clarke)
- Do not special case address zero as an error for routines that
return addresses (symbol lookup), instead use the return as the
success/error indication and pass a pointer to return the address,
fixing 'perf test vmlinux' (the one that compares address between
vmlinux and kallsyms) on s/390, where the '_text' address is equal
to zero (Arnaldo Carvalho de Melo)
Infrastructure:
- More header sanitization, moving stuff out of util.h into
more appropriate headers and objects and sometimes creating
new ones (Arnaldo Carvalho de Melo)
- Refactor a duplicated code for obtaining config file name (Taeung Song)

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.

Yeah, agreed, its short, and it provides the output ready to be used, no
need for extra processing, up to the user to decide if one or the other
is more suitable to their needs.
As a bonus, it documents callgraphs in scripts, good deal :-)

Yes, the idea for stackcollapse-perf.py was:
- to do everything directly and emit "the right" format for the
flamegraph tools. This however is a very minimal output, and it's not
necessarily the best for perf in general.
- to provide an example of visiting callgraphs from the scripting
interface, since it's not really documented. From the commit message:
"Add stackcollapse.py script as an example of parsing call chains, and
also of using optparse to access command line options".

Pretty much. Two similar solutions were developed around the same
time. Although I have to use some awk to get "perf -g folded" in the
exact right format, and stackcollapse-perf.py does that directly.

tools: Pass arg to fdarray__filter's call back function (2016-05-25 17:27:25 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible/kernel ABI:
- Per event callchain limit: Recently we introduced a sysctl to tune the
max-stack for all events for which callchains were requested:
$ sysctl kernel.perf_event_max_stack
kernel.perf_event_max_stack = 127
Now this patch introduces a way to configure this per event, i.e. this
becomes possible:
$ perf record -e sched:*/max-stack=2/ -e block:*/max-stack=10/ -a
allowing finer tuning of how much buffer space callchains use.
This uses an u16 from the reserved space at the end, leaving another
u16 for future use.
There has been interest in even finer tuning, namely to control the
max stack for kernel and userspace callchains separately. Further
discussion is needed, we may for instance use the remaining u16 for
that and when it is present, assume that the sample_max_stack introduced
in this patch applies for the kernel, and the u16 left is used for
limiting the userspace callchain. (Arnaldo Carvalho de Melo)

perf bpf: Add sample types for 'bpf-output' event (2016-04-01 18:46:25 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Do not use events that don't have timestamps when setting 'perf trace's
base timestamp, fixing up the timestamp column for syscalls (Arnaldo Carvalho de Melo)
- Make the 'bpf-output' sample_type be the same as tracepoint's, fixing up
'perf trace's timestamp column for bpf events (Wang Nan)
- Fix PMU term format max value calculation (Kan Liang)
- Pretty print 'seccomp', 'getrandom' syscalls in 'perf trace' (Arnaldo Carvalho de Melo)
Infrastructure:
- Add support for using TSC as an ARCH timestamp when synthesizing
JIT records (Adrian Hunter)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
----------------------------------------------------------------
Adrian Hunter (3):
perf tools: Add time conversion event
perf jit: Add support for using TSC as a timestamp
perf intel-pt/bts: Define JITDUMP_USE_ARCH_TIMESTAMP
Arnaldo Carvalho de Melo (5):
perf trace: Do not process PERF_RECORD_LOST twice
perf trace: Pretty print seccomp() args
perf trace: Pretty print getrandom() args
perf trace: Introduce function to set the base timestamp
perf trace: Don't set the base timestamp using events without PERF_SAMPLE_TIME
Kan Liang (1):
perf tools: Fix PMU term format max value calculation
Wang Nan (1):
perf bpf: Add sample types for 'bpf-output' event

Hi Ingo,
Please consider pulling,
- Arnaldo
The following changes since commit fe7a2eaa71c55aadbf95d01d32df8dccc0db0646:
Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2016-02-16 08:45:56 +0100)

perf stat: Move noise/running printing into printout (2016-02-16 17:13:02 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Make 'perf record' collect CPU cache info in the perf.data file header:
$ perf record usleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.017 MB perf.data (7 samples) ]
$ perf report --header-only -I | tail -10 | head -8
# CPU cache info:
# L1 Data 32K [0-1]
# L1 Instruction 32K [0-1]
# L1 Data 32K [2-3]
# L1 Instruction 32K [2-3]
# L2 Unified 256K [0-1]
# L2 Unified 256K [2-3]
# L3 Unified 4096K [0-3]
$
Will be used in 'perf c2c' and eventually in 'perf diff' to allow, for instance
running the same workload in multiple machines and then when using 'diff' show
the hardware difference. (Jiri Olsa)
- 'perf stat' now shows shadow metrics (insn per cycle, etc) in
interval mode too. E.g:
# perf stat -I 1000 -e instructions,cycles sleep 1
# time counts unit events
1.000215928 519,620 instructions # 0.69 insn per cycle
1.000215928 752,003 cycles
<SNIP>
Infrastructure:
- libapi now can also use pr_{warning,info,debug}() and that can be
set by tools using it (Jiri Olsa)
- libapi adopts filename__read_str() from perf, adds sysfs__read_str() (Jiri Olsa)
- Add check for java alternatives cmd in jvmti Makefile, so that it manages
to automatically find the right path for the JDK devel files in Ubuntu like
systems in addition to Fedora like ones (Stephane Eranian)

At least my changes should go into perf/urgent and probably stable too.

Should any of the above fixes be cherry-picked over into perf/urgent, or are these

Hm, your pull request mail was cut short as it ends here abruptly. I figured it
out nevertheless, from the commit log:
====================>
User visible changes:
- Force period term to overload global settings, i.e. previously this
command line:
$ perf record -e 'cpu/instructions,period=20000/',cycles -c 1000 sleep 1
would result in both events having a period equal to 1000, with the fix we
get something saner:
$ perf evlist -v | grep period
cpu/instructions,period=20000/: ... { sample_period, sample_freq }: 20000, ...
cycles: ... { sample_period, sample_freq }: 1000 ...
$
(Jiri Olsa)
Infrastructure changes:
- Use the dummy software event with freq=0 in the twatch.py python
binding example, to avoid disabling nohz. (Arnaldo Carvalho de Melo)
- Add some missing constants to the python binding. (Arnaldo Carvalho de Melo)
- Fix mismatched declarations for elf_getphdrnum, that happens
only in the corner case where this function is not found on
the system. (Arnaldo Carvalho de Melo)
- Add build test for having ending double slash. (Jiri Olsa)
- Introduce callgraph_set for callgraph option. (Kan Liang)

Hi Ingo,
Please consider pulling, there is some more stuff in queue to be
processed, but better send in smaller batches,

perf symbols: Convert lseek + read to pread (2015-01-29 17:02:01 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Show precise number of samples in at the end of a 'record' session, if
processing build ids, since we will then traverse the whole perf.data file
and see all the PERF_RECORD_SAMPLE records, otherwise stop showing the
previous off-base heuristicly counted number of "samples" (Namhyung Kim).
- Support to read compressed module from build-id cache (Namhyung Kim)
Infrastructure:
- Cache eh/debug frame offset for dwarf unwind (Namhyung Kim)
- Set header version correctly in all cases (Namhyung Kim)
- Set attr.task bit for a tracking event, to be consistent (Namhyung Kim)
perf tools: Use perf_data_file__fd() consistently
perf symbols: Convert lseek + read to pread
- Don't rely on malloc working for sz 0, fixing another problem when
using uClibc (Vineet Gupta)
- Provide stub for missing pthread_attr_setaffinity_np for libcs where this
is not available, such as uClibc (Vineet Gupta)

So a bit of background: sloppy, abusive contributors not willing to
change get ignored after some time. For example Andi got such a bad
track record in the x86 and perf space with me that all your mails go
to /dev/null currently. (I only saw this one because Namhyung replied
to it.)
Andi, as I explained it to you previously, if you want me to merge
patches from you then you need to 1) improve the way you work 2) send
it to someone who is willing to deal with you and sign off on it and
forward it to me.
Seems like you managed to burn up your goodwill with Arnaldo as well.
You need to find someone else willing to pay the expense of dealing
with your passive-aggressive style.
Just a quick example of your abuse: for example you know it perfectly
well that perf is well maintained, a simple 'git log tools/perf/' will
tell you that there's a steady stream of patches going in and that
perf contributors are busy.
Yet in this mail you actually lie about that: you pretend that you
don't know that most Linux maintainers have trouble working with you,
you pretend that perf is "unmaintained", you pretend that you don't
know who is maintaining it, just to create unfair pressure on Arnaldo
...
That kind of approach really sucks, and if you run out of people's
patience with petty office tactics like that then you should not fault
them, you should fault yourself.
Thanks,
Ingo

perf trace: Tell arg formatters the arg index (2013-09-02 16:40:40 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
. 'perf trace' arg formatting improvements to allow masking arguments
in syscalls such as futex and open, where the some arguments are
ignored and thus should not be printed depending on other args.
. Beautify futex open, openat, open_by_handle_at, lseek and futex syscalls.
. Add dummy software event to use when wanting just to keep receiving
PERF_RECORD_{MMAP,COMM,etc}, add test for it, from Adrian Hunter.
. Fix symbol offset computation for some dsos in 'perf script', from David Ahern.
. Skip unsupported hardware events in 'perf list', from Namhyung Kim.
