Research direction

Start by reviewing the cpufeatures AVX-512 support added in #862 and the feature list in this issue. Trace how existing AVX-512 capabilities are detected, then account for the listed features using their relevant CPUID registers. Done means the unchecked features are supported consistently with the already checked entries.

Written by the indexing model from the issue text.

Description

#862 added initial support for AVX-512, however the following features are still unsupported:

  • avx512vbmi
  • avx512vbmi2
  • avx512vpopcntdq
  • avx512vnni
  • avx512bitalg
  • avx512bf16
  • avx512vp2intersect

These use different CPUID registers than the others (e.g. ecx)

Edit: updated after #1035
