/proc/profile - kernel profiling
- /proc/profile (since Linux 2.4)
- This file is present only if the kernel was booted with the
profile=1 command-line option. It exposes kernel profiling
information in a binary format for use by readprofile(1). 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.
