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.
