Subject: [PATCH v3 00/15] KVM/arm64: Add NV support for ERET and PAuth
Date: Thu, 21 Mar 2024 15:53:41 +0000 [thread overview]
Message-ID: <20240321155356.3236459-1-maz@kernel.org> (raw)
This is the third version of this series introducing ERET and PAuth
support for NV guests, and now the base prefix for the NV support
series.
Thanks again to Joey for reviewing a large part of the series!
* From v2 [2]
- Enforce that both Address and Generic authentication use the same
algorithm
- Reduce PAuth trapping by eagerly setting the HCR_EL2.API/APK bits
- Collected RBs, with thanks
- Rebased on kvmarm-6.9
* From v1 [1]:
- Don't repaint the ISS_ERET* definitions, but provide reasonable
helpers instead
- Dropped superfluous VNCR_EL2 definition
- Amended comments and creative spelling
