Hi Tom,
Reccentlly I sent this patch set to change DxeIpl code to use CpuPageTableLib
to create page table. I have done some test on Intel CPU to make sure that the
page table created by DxeIpl before the change is the same as the page table
created by DxeIpl after the change. But there was a remaining case that I
didn't cover. The case is that PcdPteMemoryEncryptionAddressOrMask, PcdGhcbBase
and PcdGhcbSize are not zero(when memory encryption is enabled on AMD
processors supporting the SEV feature).
So could you please help do a test on AMD processor to make sure that the SEV
feature still works good with this pacth set?
Yes, I can test it.
Thanks,
Tom
Thanks,
Dun
