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. -- Sathyanarayanan Kuppuswamy Linux Kernel Developer
