Subject: [PATCHv2 0/3] tracing: function graph output for wakeup tracer
Date: Thu, 23 Sep 2010 14:00:50 +0200 [thread overview]
Message-ID: <1285243253-7372-1-git-send-email-jolsa@redhat.com> (raw)
hi,
adding function graph output to irqsoff tracer.
The graph output is enabled by setting new 'display-graph'
trace option.
The v2 updates are based on comments by Frederic Weisbecker
and Steven Rostedt, also rebased to latest master.
v2:
- librarized common functions from irqs/preemptoff tracers
- using local_save_flags instead disabling irqs to get the flags
in wakeup_graph_return/wakeup_graph_entry
attached patches:
- 1/3 proper check for irq_depth routines
- 2/3 librarize graph related irqs/preempts off calls
- 3/3 graph support for wakeup tracer
plz let me know what you think
wbr,
jirka
