This is the same as v4, except for the following minor changes: - moving the KVM_X86_SEV_VMSA_FEATURES attribute to a separate group, KVM_X86_GRP_SEV [Isaku] - as part of the previous change, retroactively define group 0 as "KVM_X86_GRP_SYSTEM" - squashing in the "fixup! KVM: SEV: sync FPU and AVX state at LAUNCH_UPDATE_VMSA time" patch - disabling FPU and AVX sync for the old-style KVM_SEV_ES_INIT ioctl [Michael] - adding an fstp instruction to the new test case, in order to keep the x87 stack balanced (just for cleanliness/paranoia) Paolo Bonzini (16): KVM: SVM: Compile sev.c if and only if CONFIG_KVM_AMD_SEV=y KVM: x86: use u64_to_user_ptr() KVM: introduce new vendor op for KVM_GET_DEVICE_ATTR KVM: SEV: publish supported VMSA features KVM: SEV: store VMSA features in kvm_sev_info KVM: x86: add fields to struct kvm_arch for CoCo features KVM: x86: Add supported_vm_types to kvm_caps KVM: SEV: introduce to_kvm_sev_info KVM: SEV: define VM types for SEV and SEV-ES KVM: SEV: sync FPU and AVX state at LAUNCH_UPDATE_VMSA time KVM: SEV: introduce KVM_SEV_INIT2 operation KVM: SEV: allow SEV-ES DebugSwap again selftests: kvm: add tests for KVM_SEV_INIT2 selftests: kvm: switch to using KVM_X86_*_VM selftests: kvm: split "launch" phase of SEV VM creation selftests: kvm: add test for transferring FPU state into VMSA Sean Christopherson (1): KVM: SVM: Invert handling of SEV and SEV_ES feature flags Documentation/virt/kvm/api.rst | 2 + .../virt/kvm/x86/amd-memory-encryption.rst | 52 ++++- arch/x86/include/asm/fpu/api.h | 3 + arch/x86/include/asm/kvm-x86-ops.h | 1 + arch/x86/include/asm/kvm_host.h | 8 +- arch/x86/include/uapi/asm/kvm.h | 20 +- arch/x86/kernel/fpu/xstate.c | 1 + arch/x86/kernel/fpu/xstate.h | 2 - arch/x86/kvm/Makefile | 7 +- arch/x86/kvm/cpuid.c | 2 +- arch/x86/kvm/svm/sev.c | 190 ++++++++++++++---- arch/x86/kvm/svm/svm.c | 27 ++- arch/x86/kvm/svm/svm.h | 54 +++-- arch/x86/kvm/x86.c | 165 +++++++++------ arch/x86/kvm/x86.h | 2 + tools/testing/selftests/kvm/Makefile | 1 + .../selftests/kvm/include/kvm_util_base.h | 11 +- .../selftests/kvm/include/x86_64/processor.h | 6 - .../selftests/kvm/include/x86_64/sev.h | 19 +- tools/testing/selftests/kvm/lib/kvm_util.c | 1 - .../selftests/kvm/lib/x86_64/processor.c | 14 +- tools/testing/selftests/kvm/lib/x86_64/sev.c | 44 +++- .../selftests/kvm/set_memory_region_test.c | 8 +- .../selftests/kvm/x86_64/sev_init2_tests.c | 152 ++++++++++++++ .../selftests/kvm/x86_64/sev_smoke_test.c | 96 ++++++++- 25 files changed, 703 insertions(+), 185 deletions(-) create mode 100644 tools/testing/selftests/kvm/x86_64/sev_init2_tests.c -- 2.43.0
