Subject: [PATCH v4 26/27] KVM: arm64: selftests: Add SME system registers to get-reg-list
Date: Fri, 14 Feb 2025 01:58:09 +0000 [thread overview]
Message-ID: <20250214-kvm-arm64-sme-v4-26-d64a681adcc2@kernel.org> (raw)
In-Reply-To: <20250214-kvm-arm64-sme-v4-0-d64a681adcc2@kernel.org>
SME adds a number of new system registers, update get-reg-list to check for
them based on the visibility of SME.
