    perf timechart: Add a power-only mode · 39a90a8e
    Arjan van de Ven authored
    For doing work on the Linux power management components, I need to
    make long (30+ seconds) traces. Currently, this then results in a
    HUGE svg file, with mostly process data that isn't interesting.
    
    This patch adds a --power-only mode to perf timechart that only
    outputs the CPU power section of the SVG; this significantly
    reduces the size of the SVG file, making even 30+ second traces
    viewable with inkscape.
    
    As a minor tweak for the same effect, the minimum text size is
    decreased; current inkscape cannot zoom in deep enough to show text
    this small, but it reduces inkscape compute time.
