OK, thanks. I'll expand it to allow 24 bits of (physical) APIC ID then, since it's no longer limited to CPUs without X2APIC. Then we can refrain from doing parallel bringup for SEV-ES guests, as you suggest.
What precisely is the check I should be using for that? [unhandled content-type:application/pkcs7-signature] | |
