Gerd,
I agree with your needs that want X2 APIC even the actual processor number in
BIOS phase <= 255.
Question: Is it possible that BIOS stays at XAPIC, and later OS switches to X2
APIC when the maximum CPU count > 255?
I am thinking about adding a new PCD to tell MP code switch to x2 apic in the
first time AP wakes up. Possible timeline for the code change is
about within 1 month. Do you think it can meet your needs?
Thanks,
Ray
