Subject: [PATCH v12 28/29] KVM: arm64: selftests: Add SME system registers to get-reg-list
Date: Thu, 09 Jul 2026 19:27:49 +0100 [thread overview]
Message-ID: <20260709-kvm-arm64-sme-v12-28-d0301d79ef58@kernel.org> (raw)
In-Reply-To: <20260709-kvm-arm64-sme-v12-0-d0301d79ef58@kernel.org>
SME adds a number of new system registers, update get-reg-list to check for
them based on the visibility of SME.
