trace_start
NAME
trace_start - start collecting driver trace
SYNOPSIS
void trace_start(string filename, int auto_stop_sec = 30)
DESCRIPTION
Calling this function will start collecting tracing information from the
driver. This includes LPC function level execution information.
The trace collection will stop and write the json data to `filename` on
`trace_end()` or after `auto_stop_sec` seconds, which defaults to 30
seconds.
Note: do not leave tracing enabled for too long or you will risk running
out of memory.
ANALYSIS
To read and analyze the json file, use Chrome or Firefox Developer Tools
Performance tab.
