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

You can add the '-pg' parameter to the specified module in the

makefile to only analyze the content of the module.
