From: Naveen N Rao (AMD)
Date: Mon Feb 03 2025 - 01:40:09 EST


Patch 1 adds support for up to 4096 vcpus with x2AVIC, and is unchanged
since v1:
http://lkml.kernel.org/r/20241008171156.11972-1-suravee.suthikulpanit@xxxxxxx

Patch 2 is new and limits the value that is programmed into
AVIC_PHYSICAL_MAX_INDEX in the VMCB based on the max APIC ID indicated
by the VMM.
