## NAME
       /proc/profile - kernel profiling

## DESCRIPTION
       _/proc/profile_ (since Linux 2.4)
              This file is present only if the kernel was booted with the _profile=1_ command-line op‐
              tion.   It exposes kernel profiling information in a binary format for use by **readpro‐**
              [**file**(1)](https://www.chedong.com/phpMan.php/man/file/1/markdown).  Writing (e.g., an empty string) to this file resets the profiling  counters;
              on  some  architectures,  writing  a  binary  integer  "profiling  multiplier" of size
              _sizeof(int)_ sets the profiling interrupt frequency.
