help
Say Y here to enable the extended profiling support mechanisms used
by profilers such as OProfile.
config OPROFILE
tristate "OProfile system profiling (EXPERIMENTAL)"
depends on PROFILING
help
OProfile is a profiling system capable of profiling the
whole system, include the kernel, kernel modules, libraries,
and applications.
If unsure, say N.
