  This tool is designed to assist kernel and OS developers in optimizing
  their linux stack's suspend/resume time. Using a kernel image built with a
  few extra options enabled, the tool will execute a suspend and will
  capture dmesg and ftrace data until resume is complete. This data is
  transformed into a device timeline and a callgraph to give a quick and
  detailed view of which devices and callbacks are taking the most time in
  suspend/resume. The output is a single html file which can be viewed in
  firefox or chrome.
