Subject: [PATCH v3 0/4] Allow AVIC's IPI virtualization to be optional
Date: Mon, 2 Oct 2023 14:57:19 +0300 [thread overview]
Message-ID: <20231002115723.175344-1-mlevitsk@redhat.com> (raw)
Hi!
This patch allows AVIC's ICR emulation to be optional and thus allows
to workaround AVIC's errata #1235 by disabling this portion of the feature.
This is v3 of my patch series 'AVIC bugfixes and workarounds' including
review feedback.
Best regards,
Maxim Levitsky
