Subject: [GIT PULL 00/10] perf/core improvements and fixes
From: Arnaldo Carvalho de Melo <acme@...hat.com>
Hi Ingo,
Please consider pulling,

Test results at the end of this message, as usual.
The following changes since commit 5b485629ba0d5d027880769ff467c587b24b4bde:
kprobes, extable: Identify kprobes trampolines as kernel text area (2017-01-14 08:38:05 +0100)

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.
