Subject: [PATCH v3 0/2] KVM: SVM: Add support for 4096 vcpus with x2AVIC
Date: Thu, 20 Feb 2025 13:08:01 +0530	[thread overview]
Message-ID: <cover.1740036492.git.naveen@kernel.org> (raw)

This is v3 of the series posted at:
http://lkml.kernel.org/r/cover.1738563890.git.naveen@kernel.org

The first patch adds support for up to 4096 vcpus with x2AVIC, while the 
second patch limits the value that is programmed into 
AVIC_PHYSICAL_MAX_INDEX in the VMCB based on the max APIC ID indicated 
by the VMM.

Changes since v2:
- Patch 1: Free allocated pages in avic_vm_destroy()
- Patch 2: Rename x2apic_mode parameter of avic_get_max_physical_id() to 
  just x2apic to avoid build issue with similarly named global variable.
