[v2] KVM: SVM: Optimize AVIC incomplete IPI #vmexit handling

[PATCH V2 0/2] KVM: SVM: Optimize AVIC incomplete IPI #vmexit handling

Posted by Suravee Suthikulpanit 4 years ago

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

Regards,
Suravee

Change from v1: (https://lore.kernel.org/lkml/20220414051151.77710-1-suravee.suthikulpanit@amd.com/T/)
 * Rebased on top of Linux 5.18-rc3
 * Patch 1/2:
    - Update commit shortlog to be more meaningful
    - Refactor to remove x2AVIC related logic for now, which will be included
      in the x2AVIC patch series.
