Frédéric Weisbecker	7c572ac0cf	tracing/ftrace: don't consume unhandled entries by boot tracer ... When the boot tracer can't handle an entry output, it returns 1. It should return 0 to relay on other output functions. Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>	2008-10-14 10:38:52 +02:00
Frédéric Weisbecker	d13744cd6e	tracing/ftrace: add the boot tracer ... Add the boot/initcall tracer. It's primary purpose is to be able to trace the initcalls. It is intended to be used with scripts/bootgraph.pl after some small improvements. Note that it is not active after its init. To avoid tracing (and so crashing) before the whole tracing engine init, you have to explicitly call start_boot_trace() after do_pre_smp_initcalls() to enable it.
