Title:
[SKL]Export XSAVE AVX state in /proc/pid
Status in intel:
Fix Committed
Status in linux package in Ubuntu:
Incomplete
Bug description:
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: 5.2
Target Release: 19.10
