It compiles for all minor versions of armv8.x with or without AES, or SHA2, or both. -What works: - -* Most algorithms are working with Neon optimizations, 2-way parallel when applicable. -* AES is working for Shavite and Echo. -* SHA is working for all algos. -* stratum+ssl and stratum+tcp are working, GBT is untested but expected to work. -* all configurations options work as usual. - Known problems: * Verthash algo is not working. * MacOS is not working natively, workaround with linux VM. * CPU and feature detection and reporting is incomplete. -* Groestl: AES mostly working but slower that unoptimized. * Fugue: multiple issues not AES related, using unoptimized. * Some algorithms too difficult to test with a CPU are not optimized for NEON. Short term plan: * Figure out what's going on with verthash. +* Fugue AES. +* Migrate NEON to more algos. Medium term: * Detection of ARM CPU model and architecture minor version. -* Fugue & Groestl AES performance, needs a breakthrough for slow shuffles. * Find NEON optimization opportunities that exploit it's architecture and instruction set. * Apply lessons learned to x86_64. * SHA512, x86_64 & AArch64.
