Cover letter [PATCH 0/5] crypto: arm64 - disable NEON across scatterwalk API calls
Quoted 5 lines · Ard Biesheuvel
Note that the remaining crypto drivers simply operate on fixed buffers, so while the RT crowd may still feel the need to disable those (and the ones below as well, perhaps), they don't call back into the crypto layer like the ones updated by this series, and so there's no room for improvement there AFAICT.
Do these other drivers process all the blocks fed to them in one go under a single NEON section, or do they do a single fixed block per NEON invocation?
