Hi Buddies, I tried to profile kernel, by using readprofile I got following data.I dont know how to analyze data, document says the third column is normalized load of the procedure..calculated as ratio between number of clock ticks and length of procedure...
but I dont know what is length of procedure is taken...if some one who has done similar ...could you please suggest me how the third column values are interpretated.
thanks a lot...
