Add the basic infrastructure needed to test AMD nested SVM. Also add a first basic vmcall test. Best regards Eric This series can be found at: https://github.com/eauger/linux/tree/v5.5-amd-svm-v5 History: v4 -> v5: - Added "selftests: KVM: Remove unused x86_register enum" - reorder GPRs within gpr64_regs - removed vmcb_hva and save_area_hva from svm_test_data - remove the naming for vmcb_gpa in run_guest v3 -> v4: - gpr64_regs struct just contains 64b mode GPRs ordered as in x86_register - cleanup in run_guest (vm* instructions) and reduce clubber list. - add some comments v2 -> v3: - Took into account Vitaly's comment: - added "selftests: KVM: Replace get_gdt/idt_base() by get_gdt/idt()" - svm.h now is a copy of arch/x86/include/asm/svm.h - avoid duplicates v1 -> v2: - split into 2 patches - remove the infrastructure to run low-level sub-tests and only keep vmmcall's one. - move struct regs into processor.h - force vmcb_gpa into rax in run_guest() Eric Auger (4): selftests: KVM: Replace get_[gdt | idt]_base() by get_[gdt | idt]() selftests: KVM: Remove unused x86_register enum selftests: KVM: AMD Nested test infrastructure selftests: KVM: SVM: Add vmcall test tools/testing/selftests/kvm/Makefile | 3 +- .../selftests/kvm/include/x86_64/processor.h | 44 +-- .../selftests/kvm/include/x86_64/svm.h | 297 ++++++++++++++++++ .../selftests/kvm/include/x86_64/svm_util.h | 36 +++ tools/testing/selftests/kvm/lib/x86_64/svm.c | 159 ++++++++++ tools/testing/selftests/kvm/lib/x86_64/vmx.c | 6 +- .../selftests/kvm/x86_64/svm_vmcall_test.c | 79 +++++ 7 files changed, 598 insertions(+), 26 deletions(-) create mode 100644 tools/testing/selftests/kvm/include/x86_64/svm.h create mode 100644 tools/testing/selftests/kvm/include/x86_64/svm_util.h create mode 100644 tools/testing/selftests/kvm/lib/x86_64/svm.c create mode 100644 tools/testing/selftests/kvm/x86_64/svm_vmcall_test.c -- 2.20.1
