Early series.
Known issues:
- when nested virt is enabled, no UI response within EDK2
and a permanent wait. Workaround: -boot menu=on,splash-time=0
- Save/restore of GIC state isn't complete yet.
- Save/restore of HVF state when EL2 is enabled isn't complete yet.
- This series doesn't contain EL2 physical timer emulation, which is
needed if not leveraging the Apple vGIC.
However, this is usable and there seems to be some interest for it. Hopefully
it'll be at least somewhat useful.
PS: I can step up to maintain HVF support if needed. WHPX arm64 patch series
is coming soon too.
v1->v2:
Oops. I did a mistake when preparing my patches.
- Add hvf_arm_el2_enable(_) call to virt_set_virt
- Fix nested virt support check to add HVF
