Subject: [PATCH 0/7] KVM: x86: AVIC/APICv patch queue
Date: Mon,  6 Jun 2022 21:08:22 +0300	[thread overview]
Message-ID: <20220606180829.102503-1-mlevitsk@redhat.com> (raw)

This patch series contains a few fixes that I worked on
recently.

Also included another attempt to add inhibit
when the guest had changed apic id and/or apic base.

I also tested AVIC with full preemption and
found few bugs, which are now hopefully fixed.

Best regards,
	Maxim Levitsky
