[RFC 0/8] perf/x86: Add msr probe interface
From: Jiri Olsa
Date: Mon Mar 18 2019 - 14:21:22 EST
hi,
following up on [1], this patchset 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.
I still need to run tests on other models and verify
rapl model table properly, but I'd like to ask it
something like this would be acceptable.
Also available in:

perf/msr
thanks,
jirka
