KVM x86 selftests change for 6.4. And an AMX+XCR0 bugfix that I landed here to avoid creating a mess of unnecessary conflicts between the series to overhaul the AMX test and the related selftests changes to verify the fix. The following changes since commit d8708b80fa0e6e21bc0c9e7276ad0bccef73b6e7: KVM: Change return type of kvm_arch_vm_ioctl() to "int" (2023-03-16 10:18:07 -0400) are available in the Git repository at: https://github.com/kvm-x86/linux.git tags/kvm-x86-selftests-6.4 for you to fetch changes up to 20aef201dafba6a1ffe9daa145c7f2c525b74aae: KVM: selftests: Fix spelling mistake "perrmited" -> "permitted" (2023-04-14 10:04:51 -0700) ---------------------------------------------------------------- KVM selftests, and an AMX/XCR0 bugfix, for 6.4: - Don't advertisze XTILE_CFG in KVM_GET_SUPPORTED_CPUID if XTILE_DATA is not being reported due to userspace not opting in via prctl() - Overhaul the AMX selftests to improve coverage and cleanup the test - Misc cleanups ---------------------------------------------------------------- Aaron Lewis (9): KVM: selftests: Assert that XTILE is XSAVE-enabled KVM: selftests: Assert that both XTILE{CFG,DATA} are XSAVE-enabled KVM: selftests: Move XSAVE and OSXSAVE CPUID checks into AMX's init_regs() KVM: selftests: Check that the palette table exists before using it KVM: selftests: Check that XTILEDATA supports XFD KVM: x86: Add a helper to handle filtering of unpermitted XCR0 features KVM: selftests: Move XGETBV and XSETBV helpers to common code KVM: selftests: Add all known XFEATURE masks to common code KVM: selftests: Add test to verify KVM's supported XCR0 Ackerley Tng (1): KVM: selftests: Adjust VM's initial stack address to align with SysV ABI spec Anish Moorthy (1): KVM: selftests: Fix nsec to sec conversion in demand_paging_test Colin Ian King (1): KVM: selftests: Fix spelling mistake "perrmited" -> "permitted" Hao Ge (1): KVM: selftests: Close opened file descriptor in stable_tsc_check_supported() Ivan Orlov (1): KVM: selftests: Add 'malloc' failure check in vcpu_save_state Like Xu (2): KVM: selftests: Add a helper to read kvm boolean module parameters KVM: selftests: Report enable_pmu module value when test is skipped Mingwei Zhang (6): KVM: selftests: Add a fully functional "struct xstate" for x86 KVM: selftests: Fix an error in comment of amx_test KVM: selftests: Enable checking on xcomp_bv in amx_test KVM: selftests: Add check of CR0.TS in the #NM handler in amx_test KVM: selftests: Assert that XTILE_DATA is set in IA32_XFD on #NM KVM: selftests: Verify XTILE_DATA in XSTATE isn't affected by IA32_XFD Sean Christopherson (2): KVM: x86: Filter out XTILE_CFG if XTILE_DATA isn't permitted KVM: selftests: Rework dynamic XFeature helper to take mask, not bit arch/x86/kvm/cpuid.c | 2 +- arch/x86/kvm/x86.c | 4 +- arch/x86/kvm/x86.h | 29 +++++ tools/testing/selftests/kvm/Makefile | 1 + tools/testing/selftests/kvm/demand_paging_test.c | 2 +- .../testing/selftests/kvm/include/kvm_util_base.h | 1 + .../selftests/kvm/include/x86_64/processor.h | 83 +++++++++++-- tools/testing/selftests/kvm/lib/kvm_util.c | 5 + tools/testing/selftests/kvm/lib/x86_64/processor.c | 36 ++++-- tools/testing/selftests/kvm/x86_64/amx_test.c | 118 ++++++++---------- .../selftests/kvm/x86_64/pmu_event_filter_test.c | 1 + .../kvm/x86_64/vmx_nested_tsc_scaling_test.c | 8 +- .../selftests/kvm/x86_64/vmx_pmu_caps_test.c | 1 + .../testing/selftests/kvm/x86_64/xcr0_cpuid_test.c | 132 +++++++++++++++++++++ 14 files changed, 326 insertions(+), 97 deletions(-) create mode 100644 tools/testing/selftests/kvm/x86_64/xcr0_cpuid_test.c
