Enable gprof profiling support. This will cause the compiler to
generate additional code to support profiling. This will also
cause the linker to include the gmon.out file in the final
executable.
Add the "-pg" parameter to the Makefile when compiling to obtain
the function call graph of the specified module. If you do this,
please enable "CONFIG_FRAME_POINTER"

Enable gprof profiling for all code, it will instrument
all code, which will cause a large performance penalty for the code.
You can add the '-pg' parameter to the specified module in the
