Subject: [RFC GIT PULL] perf updates
Date: Thu, 6 Jan 2011 15:51:51 +0100 [thread overview]
Message-ID: <1294325513-14276-1-git-send-email-fweisbec@gmail.com> (raw)
Ingo,
Please pull the perf/core branch that can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/random-tracing.git
perf/core
Soeren reported some time ago that callchains were broken on
x86_64 with cpu-clock/task-clock events. After some time I
finally found the problem was in the irq low level arg saving.
It touches fragile code though, I hope some people can
have a look over the fix.
Thanks,
Frederic
