Subject: [PATCH 0/5] AVIC bugfixes and workarounds
Date: Thu, 28 Sep 2023 18:04:23 +0300 [thread overview]
Message-ID: <20230928150428.199929-1-mlevitsk@redhat.com> (raw)
Hi!
This patch series includes several fixes to AVIC I found while working
on a new version of nested AVIC code.
Also while developing it I realized that a very simple workaround for
AVIC's errata #1235 exists and included it in this patch series as well.
Best regards,
Maxim Levitsky
