Essentially AVX support, plus a few minor cleanups. Far more noteworth is what's not in this pull request. For 6.14, I want to I want to land series with KVM-selftests-tree-wide impact: one that changes^fixes the prototype for vcpu_get_reg(), and another that uses the kernel's canonical $(ARCH) directory scheme instead of KVM selftests' homebrewed $(ARCH_DIR). My plan is to refresh both series after all arch pull requests for 6.13 have landed, and then pester you incessantly to apply them :-) https://lore.kernel.org/all/20241009154953.1073471-1-seanjc@xxxxxxxxxx https://lore.kernel.org/all/20240826190116.145945-1-seanjc@xxxxxxxxxx The following changes since commit 81983758430957d9a5cb3333fe324fd70cf63e7e: Linux 6.12-rc5 (2024-10-27 12:52:02 -1000) are available in the Git repository at: https://github.com/kvm-x86/linux.git tags/kvm-x86-selftests-6.13 for you to fetch changes up to 89f8869835e4da836bc60ab20568b7864706f94b: KVM: selftests: Ensure KVM supports AVX for SEV-ES VMSA FPU test (2024-11-01 09:26:37 -0700) ---------------------------------------------------------------- KVM selftests changes for 6.13 - Enable XFAM-based features by default for all selftests VMs, which will allow removing the "no AVX" restriction. ---------------------------------------------------------------- Ba Jing (1): KVM: selftests: Remove unused macro in the hardware disable test Jiapeng Chong (1): KVM: selftests: Use ARRAY_SIZE for array length Sean Christopherson (10): KVM: selftests: Precisely mask off dynamic fields in CPUID test KVM: selftests: Mask off OSPKE and OSXSAVE when comparing CPUID entries KVM: selftests: Rework OSXSAVE CR4=>CPUID test to play nice with AVX insns KVM: selftests: Configure XCR0 to max supported value by default KVM: selftests: Verify XCR0 can be "downgraded" and "upgraded" KVM: selftests: Drop manual CR4.OSXSAVE enabling from CR4/CPUID sync test KVM: selftests: Drop manual XCR0 configuration from AMX test KVM: selftests: Drop manual XCR0 configuration from state test KVM: selftests: Drop manual XCR0 configuration from SEV smoke test KVM: selftests: Ensure KVM supports AVX for SEV-ES VMSA FPU test .../testing/selftests/kvm/hardware_disable_test.c | 1 - .../selftests/kvm/include/x86_64/processor.h | 5 ++ tools/testing/selftests/kvm/lib/x86_64/processor.c | 24 ++++++++ tools/testing/selftests/kvm/x86_64/amx_test.c | 23 ++------ tools/testing/selftests/kvm/x86_64/cpuid_test.c | 67 ++++++++++++++-------- .../selftests/kvm/x86_64/cr4_cpuid_sync_test.c | 53 +++++++++++------ tools/testing/selftests/kvm/x86_64/debug_regs.c | 2 +- .../testing/selftests/kvm/x86_64/sev_smoke_test.c | 19 ++---- tools/testing/selftests/kvm/x86_64/state_test.c | 5 -- .../testing/selftests/kvm/x86_64/xcr0_cpuid_test.c | 11 +++- 10 files changed, 123 insertions(+), 87 deletions(-)
