* rt-graph: input to real-time plots is processed using real-time timestampsJonathan2012-03-08
| | | | | | | | | Each plot processes only the records which fit within the time window displayed. When passing records into a real-time plot, kernelshark will now decide if a record is within the current time window using real-time timestamps, instead of the old ftrace timestamps. This change also enables infinite zooming into the real-time plots.

* rt-graph: real-time graph displays current jobJonathan2012-03-07
| | | | | Logic is added to extract current job / release / deadline from a time. Hovering over a location in an real-time task plot will show this.
* rt-graph: real-time plots display info popupJonathan2012-03-06
| | | | | When you hover close enough to an events time, the event name will display. This time is based on _litmus_ time, not record time.

| | | | | Vertical lines mark events which were run either with the tasks pid or ran on the task's cpu while it is executing.

* parse-events: Allow expressions in __print_symbolic() fieldsStefan Hajnoczi2012-02-08
| | | | | | | | | | | | | | | | | | The __print_symbolic() function takes a sequence of key-value pairs for pretty-printing a constant. The new kvm:kvm_exit print fmt uses the expression: __print_symbolic(..., { 0x040 + 1, "DB excp" }, ...) Currently only atoms are supported and this print fmt fails to parse. This patch adds support for expressions instead of just atoms so that 0x040 + 1 is parsed successfully.

* trace-cmd: fix length calculation for padding eventsDavid Sharp2012-01-27
| | | | | | | | | | | | | Padding events store size in bytes, not words. Usually this ends up pushing the parser off the current page, but occasionally not, and when not, it ends up desynchronizing the parser from the event stream. This would manifest as a lot of "ug!" messages from trace-cmd, and kernelshark crashing before displaying the UI.

* blk plugin: replace BLK_TC_BARRIER with BLK_TC_FLUSH/BLK_TC_FUAStefan Hajnoczi2012-01-09
| | | | | | | | | | | | | | | | | | | | | The BLK_TC_BARRIER flag was dropped in Linux commit c09c47caedc in August 2011. The blk plugin fails to build against recent kernel headers. Since no flag bits were left, the new BLK_TC_FLUSH flag reused the BLK_TC_BARRIER bit. The new BLK_TC_FUA flag was also added. This patch updates fill_rwbs() to reflect the new BLK_TC_FLUSH/BLK_TC_FUA flags. This allows plugin_blk.c to build successfully on recent kernels. Most of the patch deals with detecting old vs new kernel headers so we can build successfully on both. (Namhyung Kim recommended using the makefile check used by perf and other tools) Link: http://lkml.kernel.org/r/1326108639-13904-1-git-send-email-stefanha@linux.vnet.ibm.com Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Cc: Namhyung Kim <namhyung@gmail.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* parse-events: Fix %pM print format arg handlingSteven Rostedt2012-01-09
| | | | | | | | | | | | When %pM is used, the arg value must be a 6 byte character that will be printed as a 6 byte MAC address. But the code does a break over the main code which updates the current processing arg to point to the next arg. If there are other print arguments after a %pM, they will be off by one. The next arg will still be processing the %pM arg. Reported-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

* parse-events: Add support to show migrate disable counterSteven Rostedt2011-11-16
| | | | | | | The RT kernel added a migrate disable counter in all events. Add support to show this in the latency format. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* parse-events: Add support for "%.*s" in bprintk eventsSteven Rostedt2011-11-15
| | | | | | | | | The arg notation of '*' in bprintks is not handled by the parser. Implement it so that they show up properly in the output and do not kill the tracer from reporting events. Reported-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* parse-event: Let filtering numbers by string use function namesSteven Rostedt2011-11-15
| | | | | | | | | As a pointer can be converted into a function name, let the filters work with the function name as well as with the pointer number. If the comparison expects a string, then convert numbers into functions, but only when the number is the same size as a long. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

* parse-event: Fix parsing of __print_flags() in TP_printk()Steven Rostedt2011-11-07
| | | | | | | | | | | | A update is made to the sched:sched_switch event that adds some logic to the first parameter of the __print_flags() that shows the state of tasks. This change cause trace-cmd to fail parsing the flags. A simple fix is needed to have the parser be able to process ops within the argument.

* trace-cmd: Do not record all events twice in extractSteven Rostedt2011-10-14
| | | | | | | | If -a is set with trace-cmd extract, simply ignore it, otherwise, all events will be recorded twice. Once at this location, and once during extracting. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* trace-cmd: Do not use threads for extractSteven Rostedt2011-10-14
| | | | | | | | | | | | | | Currently the trace-cmd extract function uses the forked threads to read the data from the ring buffers. As this is not a live trace and the program does not end till all the buffers are flushed to disk, there is no need to use the threads. Just serially read each buffer into a file and then pull them together normally. This also fixes a bug that was triggered in the kernel where reading the trace_pipe_raw file after EOF will yield the last page again, causing the trace-cmd extract to produce duplicate pages.

* trace-cmd: Use splice to filter out rest of bufferSteven Rostedt2011-10-14
| | | | | | | | | When the main thread tells the recorders that they are finished, have the recorders still use splice till all data is read that splice can handle (full page sizes only). Then use the read function for the rest. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
