Subject: [PATCH v2 0/4] AVIC bugfixes and workarounds
Date: Thu, 28 Sep 2023 20:33:50 +0300 [thread overview]
Message-ID: <20230928173354.217464-1-mlevitsk@redhat.com> (raw)
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.
changes since v2:
- added 'fixes' tags
- reworked workaround for avic errata #1235
- dropped iommu patch as it is no longer needed.
Best regards,
Maxim Levitsky
