Subject: [PATCH v4 03/21] arm64/sysreg: Update system registers for SME 2 and 2.1
Date: Mon, 16 Jan 2023 16:04:38 +0000 [thread overview]
Message-ID: <20221208-arm64-sme2-v4-3-f2fa0aef982f@kernel.org> (raw)
In-Reply-To: <20221208-arm64-sme2-v4-0-f2fa0aef982f@kernel.org>
FEAT_SME2 and FEAT_SME2P1 introduce several new SME features which can
be enumerated via ID_AA64SMFR0_EL1 and a new register ZT0 access to
which is controlled via SMCR_ELn, add the relevant register description.
