Environment: Platform: Intel(R) Xeon(R) Platinum 8487C (Sapphire Rapids) CPU Architecture: x86_64 Host OS: Red Hat Enterprise Linux 9 (Ootpa) Host kernel: Linux 6.1 release gcc: gcc (GCC) 11.2.1 20220127 (Red Hat 11.2.1-9) Host kernel source: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git Branch: master Commit: 830b3c68 Qemu source: https://git.qemu.org/git/qemu.git Branch: master Commit: 5204b499 kvm-unit-tests source: https://gitlab.com/kvm-unit-tests/kvm-unit-tests.git Branch: master Commit: 7cefda524604fe1138333315ce06224d4d864dab 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: BUILD_HEAD=7cefda52 timeout -k 1s --foreground 90s /usr/local/bin/qemu-system-x86_64 --no-reboot -nodefaults -device pc-testdev -device isa-debug-exit,iobase=0xf4,iosize=0x4 -vnc none -serial stdio -device pci-testdev -machine accel=kvm -kernel /tmp/tmp.6qzCjJnrIy -smp 1 -cpu host,migratable=no # -initrd /tmp/tmp.yEVIxAWSsB enabling apic smp: waiting for 0 APs paging enabled cr0 = 80010011 cr3 = 1007000 cr4 = 20 PMU version: 2 SKIP: PEBS not enumerated in PERF_CAPABILITIES SUMMARY: 1 tests, 1 skipped SKIP pmu_pebs (1 tests, 1 skipped) Expected Result: pmu_pebs successfully executed
