Description
There is some interest to separate AVX512 using processes from non AVX processes to get higher frequency.

A user space tool doing this needs to know whether AVX is used. One way would be to export the information from the XSAVE state from the last context switch in /proc/pid/*
Should report if AVX or AVX512 state is non INIT.

Target Kernel: TBD
Target Release: 19.04
