Subject: [PATCH v2 0/3] arm64/sve: Trivial optimisation for 128 bit SVE vectors
Date: Tue, 11 May 2021 17:04:43 +0100 [thread overview]
Message-ID: <20210511160446.42871-1-broonie@kernel.org> (raw)
This series is a combination of factoring out some duplicated code and a
very minor optimisation to the performance of handling converting FPSIMD
state to SVE in the live registers for 128 bit SVE vectors.
v2:
- Combine P and FFR flushing into a single macro.
Mark Brown (3):
arm64/sve: Split _sve_flush macro into separate Z and predicate
flushes
arm64/sve: Use the sve_flush macros in sve_load_from_fpsimd_state()
arm64/sve: Skip flushing Z registers with 128 bit vectors
