Hoernchen gerrit-no-reply at lists.osmocom.orgHello fixeria, laforge, Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmocore/+/19372 to look at the new patch set (#2). Change subject: libomsocoding: NEON viterbi acceleration ...................................................................... libomsocoding: NEON viterbi acceleration configure flag required to enable this: --enable-neon Although autodetection according to __ARM_NEON would work because this is only defined if the fpu is neon neon-fp16 neon-vfpv3 neon-vfpv4 neon-fp-armv8 crypto-neon-fp-armv8 doing that would lead to a unknown performance impact, so it needs to be enabled manually. Speedup is about ~1.3-1.5 on a unspecified single core Cortex A9. This requires handling a special case for RACH with len 14 which is far too short for neon and would actually incur a performance penalty of 25%.
