x86/perf: Use RET0 as default for guest_get_msrs to handle "no PMU" case (2021-03-10 16:45:09 +0100)
----------------------------------------------------------------
- Make sure PMU internal buffers are flushed for per-CPU events too and
properly handle PID/TID for large PEBS.
- Handle the case properly when there's no PMU and therefore return an
empty list of perf MSRs for VMX to switch instead of reading random
garbage from the stack.
----------------------------------------------------------------
Kan Liang (2):
perf/core: Flush PMU internal buffers for per-CPU events
perf/x86/intel: Set PERF_ATTACH_SCHED_CB for large PEBS and LBR
