2023-02-11KVM: arm64: nv: Use reg_to_encoding() to get sysreg IDOliver Upton
Avoid open-coding and just use the helper to encode the ID from the sysreg table entry. No functional change intended. Acked-by: Marc Zyngier <maz@kernel.org> Link: https://lore.kernel.org/r/20230211190742.49843-1-oliver.upton@linux.dev Signed-off-by: Oliver Upton <oliver.upton@linux.dev>
2023-02-11KVM: arm64: nv: Filter out unsupported features from ID regsMarc Zyngier
As there is a number of features that we either can't support, or don't want to support right away with NV, let's add some basic filtering so that we don't advertize silly things to the EL2 guest. Whilst we are at it, advertize FEAT_TTL as well as FEAT_GTG, which the NV implementation will implement.
