Subject: [PATCH v3 01/42] arm64: sysreg: Add ID_AA64ISAR1_EL1.LS64 encoding for FEAT_LS64WB
Date: Sat, 26 Apr 2025 13:27:55 +0100 [thread overview]
Message-ID: <20250426122836.3341523-2-maz@kernel.org> (raw)
In-Reply-To: <20250426122836.3341523-1-maz@kernel.org>
The 2024 extensions are adding yet another variant of LS64
(aptly named FEAT_LS64WB) supporting LS64 accesses to write-back
memory, as well as 32 byte single-copy atomic accesses using pairs
of FP registers.
Add the relevant encoding to ID_AA64ISAR1_EL1.LS64.
