The reasons include being significantly slower than CPU-based cryptographic operations, a history of bugs, lack of exclusive hardware access causing race conditions with the secure world, and registering implementations with too low a priority to actually be used. The driver will be removed from default ARMv7 and ARM64 kernel builds but kept buildable under COMPILE_TEST for potential future use in restricted media content processing. ## Full article daily.dev links to this article rather than hosting it.
