Heh, while you're here, here's combined pull request for the selftests changes that missed 6.14 due to the pmu_counters_test snafumi[1][2]? I'm a-ok if you want to hold off until 6.15. I have them sitting in a separate branch (selftests_6.14), and don't anticipate conflicts, so it's no trouble to carry them until the next merge window.

The theory is that modern Intel CPUs have learned new code prefetching tricks that bypass the PMU counters. - Fix a flaw in the Intel PMU counters test where it asserts that an event is counting correctly without actually knowing what the event counts on the underlying hardware. ---------------------------------------------------------------- Chen Ni (1): KVM: selftests: Remove unneeded semicolon Colton Lewis (2): KVM: selftests: Fix typos in x86's PMU counter test's macro variable use KVM: selftests: Add defines for AMD PMU CPUID features and properties Isaku Yamahata (1): KVM: selftests: Add printf attribute to _no_printf() Sean Christopherson (7): KVM: selftests: Use data load to trigger LLC references/misses in Intel PMU KVM: selftests: Add helpers for locally (un)blocking IRQs on x86 KVM: selftests: Make Intel arch events globally available in PMU counters test KVM: selftests: Only validate counts for hardware-supported arch events KVM: selftests: Remove dead code in Intel PMU counters test KVM: selftests: Drop the "feature event" param from guest test helpers KVM: selftests: Print out the actual Top-Down Slots count on failure tools/testing/selftests/kvm/access_tracking_perf_test.c | 2 +- tools/testing/selftests/kvm/include/test_util.h | 2 +- tools/testing/selftests/kvm/include/x86/processor.h | 47 +++++++++++++++++++++++++++++++++ tools/testing/selftests/kvm/x86/hyperv_ipi.c | 6 +++-- tools/testing/selftests/kvm/x86/pmu_counters_test.c | 158 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++---------------------------------------------- tools/testing/selftests/kvm/x86/svm_int_ctl_test.c | 5 +--- tools/testing/selftests/kvm/x86/ucna_injection_test.c | 2 +- tools/testing/selftests/kvm/x86/xapic_ipi_test.c | 3 ++- tools/testing/selftests/kvm/x86/xapic_state_test.c | 4 +-- tools/testing/selftests/kvm/x86/xen_shinfo_test.c | 5 +--- 10 files changed, 151 insertions(+), 83 deletions(-)
