Subject[PATCH v5 0/4] selftests: KVM: AMD Nested SVM test infrastructure
Date
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()
