Subject: [GIT PULL 00/10] perf/core improvements and fixes
Date: Wed, 7 Dec 2016 13:53:25 -0300 [thread overview]
Message-ID: <20161207165335.22835-1-acme@kernel.org> (raw)
Hi Ingo,
Please consider pulling, should get linux-next free of perf build fixdep
related race conditions on high core count machines,

perf tools: Explicitly document that --children is enabled by default (2016-12-07 12:00:35 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
Improvements:
- Improve error message when analyzing file with required events in
'perf sched timehist' (David Ahern)
Fixes:
- Force fixdep compilation to be done at the start of the build, fixing
some build race conditions in high core count machines (Jiri Olsa)
- Fix handling a zero sample->tid in 'perf sched timehist', as
sometimes that isn't the idle thread (Namhyung Kim)
Infrastructure:
- Check minimal accepted LLVM version in its feature check, 3.9 at this
time (Wang Nan)
Documentation:
- Explicitly document that --children is enabled by default (Yannick Brosseau)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
