Subject: [PATCH v7 00/11] KVM: arm64: Fixed features for protected VMs
Date: Fri, 8 Oct 2021 16:58:21 +0100 [thread overview]
Message-ID: <20211008155832.1415010-1-tabba@google.com> (raw)
Hi,
Changes since v6 [1]:
- Rebase on 5.15-rc4
- Include Marc's updated 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 [2].
This series is based on 5.15-rc4. You can find the applied series here [3].
Cheers,
/fuad
