Recently a few pmu KVM patches have been queued, and resulted into some test
failures based on the queue branch. Fix them in this series.
Patches were tested with below config:
kernel:
kvm/queue, commit 4284f0063c48
qemu:
master, commit 3a821c52e1a3
platform:
Skylake/Sapphire Rapids
v3:
1. Replaced msr test fixup with Paolo's patch at below link per
Sean's comments, change RO bits to bit 11 and 12 due to Sean's
commit 9fc222967a39 ("KVM: x86: Give host userspace full control of MSR_IA32_MISC_ENABLES")
https://lore.kernel.org/all/20220520183207.7952-1-pbonzini@xxxxxxxxxx/
2. Added helpers to check pmu verison and perf_global_ctrl MSR. [Sean]
3. Refactored pmu_lbr code with new helper.
Paolo Bonzini (1):
x86: Don't overwrite bits 11 and 12 of MSR_IA32_MISC_ENABLE
Yang Weijiang (2):
x86: Skip perf related tests when platform cannot support
x86: Check platform vPMU capabilities before run lbr tests
