# HEAD: 711486fd18596315d42cebaac3dba8c408f60a3d Documentation/filesystems/proc.txt: Add arch_status file

This adds a new ABI that the main scheduler probably doesn't want to deal
with but HPC job schedulers might want to use, the AVX512_elapsed_ms
field in the new /proc/<pid>/arch_status task status file, which allows
the user-space job scheduler to cluster such tasks, to avoid turbo
frequency drops.

fs/proc/Kconfig # 68bc30bb9f33: proc: Add /proc/<pid>/arch_s
