Subject: [PATCH 0/8] perf/x86: Rework msr probe interface
Date: Mon, 27 May 2019 23:51:21 +0200 [thread overview]
Message-ID: <20190527215129.10000-1-jolsa@kernel.org> (raw)
hi,
following up on [1], [2] and [3], this patchset adds update
attribute groups to pmu, factors out the MSR probe code and
use it in msr,cstate* and rapl PMUs.
The functionality stays the same with one exception:
the event is not exported if the rdmsr return zero
on event's msr.
And also: ;-)

Also available in:
git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
perf/msr
Tested on snb and skylake servers.
thanks,
jirka
