No. That's completely superfluous since we already check for kernel support with hwprobe(). And we can't check for Zb* and Zv* with hwcap anyhow. >As those extensions rely on vector registers, kernel vector support >is required to save the state of context switching. No. Kernel context switching is already ascertained. And we don't care about libc context support, since vectors are clobbered by function calls, e.g. for long jumps or ucontext. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
