Subject: [PATCH v6 27/28] KVM: arm64: selftests: Add SME system registers to get-reg-list
Date: Wed, 25 Jun 2025 11:48:18 +0100	[thread overview]
Message-ID: <20250625-kvm-arm64-sme-v6-27-114cff4ffe04@kernel.org> (raw)
In-Reply-To: <20250625-kvm-arm64-sme-v6-0-114cff4ffe04@kernel.org>

SME adds a number of new system registers, update get-reg-list to check for
them based on the visibility of SME.
