Profiling my Modules
Hi All, I have a kernel module which has functions which take a lot of time in execution. I am curious to know how can I profile it, and find out the functions taking most of the time. I saw Oprofile, but it seems that I will have to build the whole kernel, and also that it will be difficult to profile my module through it. Any trick or tool will do. -- Regards, Rishi Agrawal ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
