During the Kernel Summit demo of perf/ftrace/timechart, there was a feature request to have a process filter for timechart so that you can zoom into one or a few processes that you are really interested in. This patch adds basic support for this feature, the -p (--process) option now can select a PID or a process name to be shown. Multiple -p options are allowed, and the combined set will be included in the output.
