rt-graph: real-time plots display info popup

2012-03-07T04:18:16+00:00

When you hover close enough to an events time, the event name will
display. This time is based on _litmus_ time, not record time.

rt-graph: real-time tasks can be added / removed from the graph

2012-03-05T23:00:39+00:00

Currently they copy the functionality of regular task.

trace-cmd: Update man pages for 'check-events' option

2011-08-19T01:38:33+00:00

There is a new option added to the 'report' target to check event
formats of the events recorded in a trace data file. This patch updates
the documentation in the man page.

This patch also adds a new man page for 'check-events' target which
verifies event formats on the local machine.

trace-cmd: Add --func-stack option to enable function stack trace

2011-03-11T21:52:40+00:00

Added --func-stack option to trace-cmd record, that will enable the
function stack tracing, but only if the -l option (limit functions)
is used, and succeeds in filtering functions. It is known that running
the function stack trace on all functions can livelock the machine.

The output now looks like this:

          -0     [002] 64003.696572: function:             schedule
          -0     [002] 64003.696577: kernel_stack:         
=> cpu_idle (ffffffff8100a38c)
=> start_secondary (ffffffff814ab828)
       trace-cmd-4132  [003] 64003.696632: function:             schedule
       trace-cmd-4132  [003] 64003.696637: kernel_stack:

2011-03-11T20:50:01+00:00

Add -T option to perform a stacktrace on each event:

     kworker/3:2-2393  [003] 58549.282806: sched_switch:         kworker/3:2:2393 [120] S ==> trace-cmd:2603 [120]
     kworker/3:2-2393  [003] 58549.282808: kernel_stack:         
=> schedule (ffffffff814b260e)
=> worker_thread (ffffffff8106edd7)
=> kthread (ffffffff81072b43)
=> kernel_thread_helper (ffffffff814bcbe4)
          -0     [000] 58549.282866: sched_switch:         swapper:0 [120] R ==> trace-cmd:2600 [120]

trace-cmd: Add trace-cmd record --date option

2011-02-25T02:46:56+00:00

Adding the --date option to trace-cmd record (and extract) will
cause trace-cmd to write a timestamp into the ftrace buffer and
use it to mapped the ftrace buffer's timestamps with gettimeofday.

This will allow reading of the trace.dat file to be able to convert
the timestamps into actual wall time.
