[edk2-devel] [PATCH 0/6] Substract TME-MK KEY_ID_BITS from CPU max PA

[Ni, Ray]

Tom,
I would assume this won't break any AMD system because the CPUID bit doesn't declare this feature.

Gerd,
This is needed by Intel platform for TME-MK. Can you help to analyze if it has any impact to OVMF? I assume no.


Thanks,
Ray
