[0/7] KVM: x86/pmu: Four functional fixes

Message

Like Xu Nov. 12, 2021, 9:51 a.m. UTC

Hi,

The first one (patch 01) is to fix my childish code about the disallowed
fixed ctr3. 

The second one (patch 02) is to fix the aged inconsistent behaviour
about CPUID 0AH.EBX. 

The third one (patch 03/04) is to avoid perf_event creation for
unavailable Intel CPUID events.

Finally a new way is proposed to
fix amd_event_mapping[] for new AMD platforms.

Please check each commit message for more details
and let me know if there is any room for improvement,

Thanks.
