Subject: [PATCH 0/2] arm64/fp: Initialise all bits in vector control registers to known values
Date: Tue, 13 Feb 2024 15:32:44 +0000 [thread overview]
Message-ID: <20240213-arm64-fp-init-vec-cr-v1-0-7e7c2d584f26@kernel.org> (raw)
We currently do read/modify/write sequences whenever we update fields in
ZCR_EL1 and SMCR_EL1 so fields we are not explicitly handling will not
be initialised to known values, fix this. The EL2 registers are already
fully configured.
Signed-off-by: Mark Brown <broonie@kernel.org>
