237 | This tracer helps developers to optimize boot times: it records | ||
238 | the timings of the initcalls and traces key events and the identity | ||
239 | of tasks that can cause boot delays, such as context-switches. | ||
240 | |||
241 | Its aim is to be parsed by the scripts/bootgraph.pl tool to | ||
242 | produce pretty graphics about boot inefficiencies, giving a visual | ||
243 | representation of the delays during initcalls - but the raw | ||
244 | /debug/tracing/trace text output is readable too. | ||
245 | |||
246 | You must pass in initcall_debug and ftrace=initcall to the kernel | ||
247 | command line to enable this on bootup. | ||
