Subject: [PATCH v8 01/29] arm64/sysreg: Update SMIDR_EL1 to DDI0601 2025-06
Date: Tue, 02 Sep 2025 12:36:04 +0100 [thread overview]
Message-ID: <20250902-kvm-arm64-sme-v8-1-2cb2199c656c@kernel.org> (raw)
In-Reply-To: <20250902-kvm-arm64-sme-v8-0-2cb2199c656c@kernel.org>
Update the definiton of SMIDR_EL1 in the sysreg definition to reflect the
information in DD0601 2025-06. This includes somewhat more generic ways of
describing the sharing of SMCUs, more information on supported priorities
and provides additional resolution for describing affinity groups.
