Not sure how TDX will handle AP booting, are you sure it needs this
special setup as well? Otherwise a check for SEV-ES would be better
instead of the generic PATTR_GUEST_PROT_STATE.
Yes, I'm not sure either. I figure that change can be made, if needed, as
part of the TDX support.
We don't plan to set PROT_STATE. So it does not affect TDX.
For SMP, we use MADT ACPI table for AP booting.
