Subject: [PATCH RFC v2 22/22] KVM: arm64: selftests: Add SME system registers to get-reg-list
Date: Fri, 22 Dec 2023 16:21:30 +0000 [thread overview]
Message-ID: <20231222-kvm-arm64-sme-v2-22-da226cb180bb@kernel.org> (raw)
In-Reply-To: <20231222-kvm-arm64-sme-v2-0-da226cb180bb@kernel.org>
SME adds a number of new system registers, update get-reg-list to check for
them based on the visibility of SME.
