    perf: Add the timechart tool · 10274989
    Arjan van de Ven authored
    timechart is a tool to visualize what is going on in the system.
    
    The user makes a trace of what is going on with
    
     > perf record --timechart /usr/bin/some_command
    
    and then can turn the output of this into an svg file
    
     > perf timechart
    
    which then can be viewed with any SVG view; inkscape works well
    enough for me.
    
    The idea behind timechart is to create a "infinitely zoomable"
    picture; something that has high level information on a 1:1 zoom
    level, but which exposes more details every time you zoom into a
    specific area.
