The series that just keeps on growing. This started out as a smallish
series from Jinrong to add PMU counters test, but has now ballooned to be
fixes and tests (that to some extent do actually validate the fixes).
Except for the first patch, the fixes aren't tagged for stable as I don't
*think* there's anything particularly nasty, and it's not like KVM's vPMU
is bulletproof even with the fixes.
v6:
- Test LLC references/misses with CFLUSH{OPT}. [Jim]
- Make the tests play nice without PERF_CAPABILITIES. [Mingwei]
- Don't squash eventsels that happen to match an unsupported arch event. [Kan]
- Test PMC counters with forced emulation (don't ask how long it took me to
figure out how to read integer module params).
