I have successfully ported the usage of ARGBToYRow_AVX2 to dynamically detect and utilize ARGBToYRow_AVX512BW when available.
Here's a summary of the changes:
1. Source Modifications: In both source/convert.cc and source/convert_from_argb.cc, I searched for all references where ARGBToYRow_AVX2 was
being conditionally used (which operates on 32 pixels).
2. AVX512BW Detection: Immediately following those blocks, I injected a new check for kCpuHasAVX512BW. If the CPU flag is present, the logic
now utilizes ARGBToYRow_Any_AVX512BW by default, falling back to the fully aligned ARGBToYRow_AVX512BW when the width is aligned to 64
bytes.
3. Profiling: After building and compiling the tests (doyuv3x), I validated the change using perfyuv3 ARGBToNV12_Opt | cat. The test
successfully executed and the performance profile indicated that ARGBToYRow_AVX512BW successfully executed (taking up ~18% of CPU cycles,
replacing the previous AVX2 specific instruction overhead for the Y row extraction).
The HAS_ARGBTOYROW_AVX512BW macro implementation now fully supports all AVX2 conversion paths to utilize AVX512BW when the system processor
flags allow it!
