perf test: Add missing verbose output explaining the reason for failure (2016-04-19 12:39:36 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
Build fixes:
- Fix 'perf trace' build when DWARF unwind isn't available (Arnaldo Carvalho de Melo)
- Remove x86 references from arch-neutral Build, fixing it in !x86 arches,
reported as breaking the build for powerpc64le in linux-next (Arnaldo Carvalho de Melo)
Infrastructure:
- Do memset() variable 'st' using the correct size in the jit code (Colin Ian King)
- Fix postgresql ubuntu 'perf script' install instructions (Chris Phlipot)
- Use callchain_param more thoroughly when checking how callchains were
configured, eventually will be the only way to look for callchain parameters
(Arnaldo Carvalho de Melo)
- Fix some issues in the 'perf test kallsyms' entry (Arnaldo Carvalho de Melo)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
----------------------------------------------------------------
Arnaldo Carvalho de Melo (12):
perf trace: Fix build when DWARF unwind isn't available
perf evsel: Add missign class prefix to has_branch_stack method
perf script: Check sample->callchain before using it
perf callchain: Set callchain_param.enabled when parsing --call-graph
perf report: Use callchain_param.enabled instead of tool specific knob
perf tools: Ditch record_opts.callgraph_set
perf hists browser: Fold two consecutive symbol_conf.use_callchain ifs
perf top: Use callchain_param.enabled instead of symbol_conf.use_callchain
perf build: Remove x86 references from arch-neutral Build
perf symbols: Allow loading kallsyms without considering kcore files
perf test: Ignore kcore files in the "vmlinux matches kallsyms" test
perf test: Add missing verbose output explaining the reason for failure
Chris Phlipot (1):
perf script: Fix postgresql ubuntu install instructions
Colin Ian King (1):
perf jit: memset() variable 'st' using the correct size

The variable is initialized and then conditionally set to a different
value, but not used when DWARF unwinding is not available, bummer, write
1000 times: "Run make -C tools/perf build-test"...
builtin-trace.c: In function ‘cmd_trace’:
builtin-trace.c:3112:6: error: variable ‘max_stack_user_set’ set but not
used [-Werror=unused-but-set-variable]
bool max_stack_user_set = true;
^
cc1: all warnings being treated as err
Fix it by marking it as __maybe_unused.

The current instructions for setting up an Ubuntu system for using the
export-to-postgresql.py script are incorrect.
The instructions in the script have been updated to work on newer
versions of ubuntu.
-Add missing dependencies to apt-get command:
python-pyside.qtsql, libqt4-sql-psql
-Add '-s' option to createuser command to force the user to be a
superuser since the command doesn't prompt as indicated in the
current instructions.
Tested on: Ubuntu 14.04, Ubuntu 16.04(beta)

The current code is memsetting the 'struct stat' variable 'st' with the size of
'stat' (which turns out to be 1 byte) rather than the size of variable 'sz'.
Committer notes:
sizeof(function) isn't valid, the result depends on the compiler used, with
gcc, enabling pedantic warnings we get:
$ cat sizeof_function.c
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#include <stdio.h>
int main(void)
{
printf("sizeof(stat)=%zd, stat=%p\n", sizeof(stat), stat);
return 0;
}
$ readelf -sW sizeof_function | grep -w stat
49: 0000000000400630 16 FUNC WEAK HIDDEN 13 stat
$ cc -pedantic sizeof_function.c -o sizeof_function
sizeof_function.c: In function ‘main’:
sizeof_function.c:8:46: warning: invalid application of ‘sizeof’ to a function type [-Wpointer-arith]
printf("sizeof(stat)=%zd, stat=%p\n", sizeof(stat), stat);
^
$ ./sizeof_function
sizeof(stat)=1, stat=0x400630
$
Standard C, section 6.5.3.4:
"The sizeof operator shall not be applied to an expression that has function
type or an incomplete type, to the parenthesized name of such a type,
or to an expression that designates a bit-field member."

Before the support for using /proc/kcore was introduced, the kallsyms
routines used /proc/modules and the first 'perf test' entry expected
finding maps for each module in the system, which is not the case with
the kcore code. Provide a way to ignore kcore files so that the test can
have its expectations met.
Improving the test to cover kcore files as well needs to be done.

One of the branches leading to an error had no debug message emitted,
fix it, the new lines are:
# perf test -v kallsyms

Hi Ingo,
Please consider pulling, this has those 31 patches that were
blocked due to some problems (author not being the fist S-o-B, build
broken on ppc), those issues should all be fixed and then we have 14
patches more, described in the signed tag.
Regards,
- Arnaldo

perf tests bp_account: Fix build with clang-6 (2018-03-19 13:51:54 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
- Fixes for problems experienced with new gcc 8 warnings, that treated
as errors, broke the build, related to snprintf and casting issues.
(Arnaldo Carvalho de Melo, Jiri Olsa, Josh Poinboeuf)
- Fix build of new breakpoint 'perf test' entry with clang < 6, noticed
on fedora 25, 26 and 27 (Arnaldo Carvalho de Melo)
- Workaround problem with symbol resolution in 'perf annotate', using
the symbol name already present in the objdump output (Arnaldo Carvalho de Melo)
- Document 'perf top --ignore-vmlinux' (Arnaldo Carvalho de Melo)
- Fix out of bounds access on array fd when cnt is 100 in one of the
'perf test' entries, detected using 'cpptest' (Colin Ian King)
- Add support for the forced leader feature, i.e. 'perf report --group'
for a group of events not really grouped when scheduled (without using
{} to enclose the list of events in the command line) in pipe mode,
e.g.:
$ perf record -e cycles,instructions -o - kill | perf report --group -i -
- Use right type to access array elements in 'perf probe' (Masami Hiramatsu)
- Update POWER9 vendor events (those described in JSON format) (Sukadev Bhattiprolu)
- Discard head in overwrite_rb_find_range() (Yisheng Xie)
- Avoid setting 'quiet' to 'true' unnecessarily (Yisheng Xie)

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 ftrace: Add ftrace.tracer config option (2017-01-31 16:20:09 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
New features:
. Allow configuring a 'perf ftrace' default --tracer (Taeung Song)
Infrastructure:
. Sync tools/arch/{powerpc,arm}/include/uapi/asm/kvm.h and
tools/arch/x86/include/asm/cpufeatures.h (Ingo Molnar)
. Add BPF program file system pinning APIs and respective
'perf test' entry (Joe Stringer)
. Make tools tree support 'make -s' (Josh Poimboeuf)
. Reference count maps in callchains, fixing SEGFAULT when
referencing maps after it is freed (Krister Johansen)
. Create for_each_event trace points iterator (Taeung Song)
. Do not consider an error not to have any perfconfig file
(Arnaldo Carvalho de Melo
. Propagate perf_config() errors (Arnaldo Carvalho de Melo)

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.

Hi Ingo,
This comes with part of Adrian's latest pull req to support Intel PT
on tools/perf, with enough to testing it, see the example in the latest
patch in this series.
More wore patches for BTS and further Intel PT goodies will come soon,
after some issues with resolving symbols get fixed. This was something that
wasn't present last time I tested the BTS bits, so I think we should resolve
it soon, but while we do it, these patches should move things forward wrt
being able to test the stuff already in the kernel and to have access to this
hardware feature using perf.
Please consider applying,
- Arnaldo

Here are the results of the performance assessment on ARMv7, FWIW:
The results for unwind_speedup (v4) on ARMv7 are:
- libunwind: between -17% in execution time for light load (i.e. using
not-so-deep backtraces from the stress app.) and -25% for deep
backtrace (the stress_bt app.),
- libdw: no significant improvement (0-3% improvement).
The results for unwind_speedup (v3) on ARMv7 are:
- libunwind: between -29% in execution time for light load (i.e. using
not-so-deep backtraces from the stress app.) and -49% for deep
backtrace (the stress_bt app.),
- libdw: no significant improvement (0-2% improvement).
Note: v3 is faster than v4 by 13-25%, with and without the speed-up
patches. The real cause has been investigated, yet.
Cf. https://wiki.linaro.org/LEG/Engineering/TOOLS/perf-callstack-unwinding#Speed_improvement
for the details.

Jean

hi,
yep, I also found the v4 to be slower, because of the
caching code in each open.. I believe the first version
you meassured was the original, that kept all dso objects
open.. now the caching code spends more cycles
also we are not mmapping dso so far.. there's the cached
read in place
please let me know if you think it's something else
thanks for testing,
jirka
