These are the selftests changes that were originally slated for 6.14, but got omitted because of the mess with the Intel PMU counters failing due to the test trying to validate architectural events on unsupported hardware. The following changes since commit 10b2c8a67c4b8ec15f9d07d177f63b563418e948: Merge tag 'kvm-x86-fixes-6.13-rcN' of https://github.com/kvm-x86/linux into HEAD (2024-12-22 12:59:33 -0500) are available in the Git repository at: https://github.com/kvm-x86/linux.git tags/kvm-x86-selftests_6.15-1 for you to fetch changes up to 54108e73344480c3e5f3799129970009f52c59f4: KVM: selftests: Print out the actual Top-Down Slots count on failure (2025-02-12 08:34:56 -0800) ---------------------------------------------------------------- KVM selftests changes for 6.15, part 1 - Misc cleanups and prep work. - Annotate _no_printf() with "printf" so that pr_debug() statements are checked by the compiler for default builds (and pr_info() when QUIET). - Attempt to whack the last LLC references/misses mole in the Intel PMU counters test by adding a data load and doing CLFLUSH{OPT} on the data instead of the code being executed. 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 .../selftests/kvm/access_tracking_perf_test.c | 2 +- tools/testing/selftests/kvm/include/test_util.h | 2 +- .../testing/selftests/kvm/include/x86/processor.h | 47 ++++++ tools/testing/selftests/kvm/x86/hyperv_ipi.c | 6 +- .../testing/selftests/kvm/x86/pmu_counters_test.c | 158 ++++++++++++--------- tools/testing/selftests/kvm/x86/svm_int_ctl_test.c | 5 +- .../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(-)
