Subject: [PATCH v13 40/40] KVM: selftests: arm64: Add GCS registers to get-reg-list
Date: Tue, 01 Oct 2024 23:59:19 +0100 [thread overview]
Message-ID: <20241001-arm64-gcs-v13-40-222b78d87eee@kernel.org> (raw)
In-Reply-To: <20241001-arm64-gcs-v13-0-222b78d87eee@kernel.org>
GCS adds new registers GCSCR_EL1, GCSCRE0_EL1, GCSPR_EL1 and GCSPR_EL0. Add
these to those validated by get-reg-list.
