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.
- Naveen

max_vcpu_ids
