Subject: [PATCH v19 11/14] KVM: selftests: arm64: Add GCS to set_id_regs
Date: Wed, 12 Aug 2026 20:12:10 +0100	[thread overview]
Message-ID: <20260812-arm64-gcs-v19-11-9105afd828ac@kernel.org> (raw)
In-Reply-To: <20260812-arm64-gcs-v19-0-9105afd828ac@kernel.org>

Now that GCS is configurable via the ID registers update set_id_regs to
cover ID_AA64PFR1_EL1.GCS.
