Hi,

This series is an addition to below patch set:
KVM: x86/pmu: selftests: Fixes and new tests
https://lore.kernel.org/all/20231110021306.1269082-1-seanjc@google.com/

Add selftests for AMD PMU counters, including tests for basic functionality
of AMD PMU counters, numbers of counters, AMD PMU versions, PerfCtrExtCore
and AMD PerfMonV2 features. Also adds PMI tests for Intel gp and fixed counters.

All patches have been tested on both Intel and AMD machines, with one exception
AMD Guest PerfMonV2 has not been tested on my AMD machine, as does not support
PerfMonV2.

If Sean fixed the issue of not enabling forced emulation to generate #UD when
applying the "KVM: x86/pmu: selftests: Fixes and new tests" patch set, then the
patch "KVM: selftests: Add forced emulation check to fix #UD" can be dropped.

Any feedback or suggestions are greatly appreciated.

Sincerely,

Jinrong

Hi Colton,

There are no further updates to this series. I appreciate your
interest in covering AMD for PMU testing purposes.

Please feel free to modify this patch series to suit your requirements
and make any necessary adjustments. If you have any questions or need
assistance, please don't hesitate to contact me.

Thanks
