Problem: the emeraId rapids 8562Y is detected as 'haswell' (the output of auto-detect.x).
This CPU has AVX-512 and I'm not sure why this is happening.
Compiler: GCC 13.3.0
commit: b5d5783

EDIT:
With logging enabled, the reason is
libblis: Number of FMA units unknown; using 'haswell' (not 'skx') config
because there is no data for this processor in vpu_count().
