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. +# +# The following kernel build options are required: +# CONFIG_PM_DEBUG=y +# CONFIG_PM_SLEEP_DEBUG=y +# CONFIG_FTRACE=y
