Bug Detailed Description:
kvm-unit-test pmu_pebs is skipped on the linux 6.1 release kernel on Sapphire
Rapids. PEBS should be supported on SPR. However, the kvm-unit-test pmu_pebs is
skipped on SPR with linux 6.1 release kernel. In addition, kvm-unit-test
pmu_pebs can pass on Ice Lake rather than being skipped.
Reproducing Steps:
git clone https://gitlab.com/kvm-unit-tests/kvm-unit-tests.git
cd kvm-unit-tests
./configure
make standalone
cd tests
./pmu_pebs
Actual Result:
