Subject: [GIT PULL 00/14] perf/core improvements and fixes
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.
