FP4: Switch to dot product CPU variant * FP4:/ $ cat /proc/cpuinfo | grep -m 1 Features Features: fp asimd evtstrm aes pmull sha1 sha2 crc32 atomics fphp asimdhp cpuid asimdrdm lrcpc dcpop asimddp * From this, it's evident that our CPU (Snapdragon 680) supports all the features of ARMv8.2-DotProd [1]. Moreover AOSP sets this arch variant in their generic cortex-a55 ART target as well [2]. This should unlock some optimizations in different code paths.
