[PATCH 0/2] KVM: SVM: Optimize AVIC incomplete IPI #vmexit handling

From: Suravee Suthikulpanit
Date: Thu Apr 14 2022 - 01:12:19 EST


This series introduce a fast-path when handling AVIC incomplete IPI #vmexit
for AVIC and x2AVIC, and introduce a new tracepoint for the slow-path
processing.

Please note that the prereq of this series is:
[PATCH v2 00/12] Introducing AMD x2APIC Virtualization (x2AVIC) support
(https://lore.kernel.org/lkml/20220412115822.14351-2-suravee.suthikulpanit@xxxxxxx/T/)
