Subject: [PATCH v6 00/12] KVM: arm64: Fixed features for protected VMs
Date: Wed, 22 Sep 2021 13:46:52 +0100 [thread overview]
Message-ID: <20210922124704.600087-1-tabba@google.com> (raw)
Hi,
Changes since v5 [1]:
- Rebase on 5.15-rc2
- Include Marc's early exception handlers in the series
- Refactoring and fixes (Drew, Marc)
This patch series adds support for restricting CPU features for protected VMs
in KVM (pKVM). For more background, please refer to the previous series [1].
This series is based on 5.15-rc2. You can find the applied series here [2].
Cheers,
/fuad
