If you fail to read the inline responses, we can end this conversation right here.
And how did you test the prefetch, because I literally run a native benchmarking on the device right now and I see that with the patch applied I am getting 5% of performance improvement. Maybe there is an issue in the way you measure the timers? I can for sure remove them because I anyway use my own implementation that is 5-10x faster than the ffmpeg's, but I am genuinely curious how is it possible that you see different benchmarking results.
I tested with checkasm, with patch 1/2, on Linux on a Cortex A53, as-is and with the prefetch instructions removed.
