[kvm-unit-tests PATCH v3 0/2] x86/emulator: Add some tests for loading segment descriptor in emulator

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add some far ret and far jmp tests for the related x86 emulator bugs[*].
Those tests would be tested both on hardware and emulator. Enable
kvm.force_emulation_prefix to test them on emulator.

Changed from v2:
- Fix some complication errors, which are not gotten in my gcc.
- Rename lret as far ret, and rename ljmp as far jmp.

Changed from v1:
- As Sean suggested, refactor the test loop to make the code simple.

v2: https://lore.kernel.org/kvm/cover.1644311445.git.houwenlong.hwl@xxxxxxxxxxxx
