Subject: [PATCH v2 0/2] KVM: SVM: Add support for 4096 vcpus with x2AVIC
Date: Mon, 3 Feb 2025 12:07:44 +0530 [thread overview]
Message-ID: <cover.1738563890.git.naveen@kernel.org> (raw)
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@amd.com
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.
