Subject: [PATCH 0/2] KVM: arm64: Fixes and clarifications for FEAT_S1POE
Date: Tue, 1 Jul 2025 16:16:46 +0100 [thread overview]
Message-ID: <20250701151648.754785-1-maz@kernel.org> (raw)
I (almost accidentally) spotted a couple of issues with the current NV
support for S1POE:
- wi->{e0,}poe and wr->{p,u}ov are used interchangeably, and sometimes
in conjunction -- none of that makes much sense
- The two rules describing WXN are not exactly been applied to the
correct state
These two patches address these issues (not that it matters much yet,
there is no S1POE HW out there).

KVM: arm64: Remove the wi->{e0,}poe vs wr->{p,u}ov confusion
KVM: arm64: Follow specification when implementing WXN
