Subject: [PATCH 11/13] KVM: arm64: selftests: Make dependencies on VHE-specific registers explicit
Date: Mon, 29 Sep 2025 17:04:55 +0100	[thread overview]
Message-ID: <20250929160458.3351788-12-maz@kernel.org> (raw)
In-Reply-To: <20250929160458.3351788-1-maz@kernel.org>

The hyp virtual timer registers only exist when VHE is present,
Similarly, VNCR_EL2 only exists when NV2 is present.

Make these dependencies explicit.
