Sample output from command: show_delta -b "Linux version" tim_hp_run1 

This shows all the timing data relative to the line starting with the string "Linux version" (the first line of the output). The "-b" option can be used to set a different time base for the timing information."

Note that since we made all timing data relative to the first line of output, the final number at the bottom is our total kernel boot time (about 5558 milliseconds).

Compare this output to PrintkTimesSample1 or PrintkTimesSample3
