* 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.
* rt-graph: real-time plots now draw other eventsJonathan2012-03-06
| | | | | 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: Modify header to work in C++ programsSteven Rostedt2011-10-17

* trace-cmd: Add parse error checking targetVaibhav Nagarnaik2011-07-29
| | | | | | | | | | | | | | Add another target 'check-events' which parses all the event formats and returns whether there are any issues with the print format strings. With an error in the format, the return value is 22 (EINVAL) and for success, it is 0.

* parse-events: Always allocate comm for pevent_register_comm()Steven Rostedt2011-01-19
| | | | | | | | | | | The function pevent_register_comm() will allocate its own comm depending on when you execute it. This is stupid and likely to cause bugs. Make it always allocate its own comm and also change the parameter name to accept const char *. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

* parse-events: Add PRINT_BPRINTK to separate bprintk strings from dynamicSteven Rostedt2010-11-16
| | | | | | | | | | | When bprintk had a "%s",string format, the args for the bprintk used a dynamic string arg for the string. Unfortunately, this would cause the string to not be found and nothing would be printed. This patch adds a special PRINT_BPRINTK type that lets the processing do something special with the bprintk strings. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* parse-events: Make trace_seq dynamically expand its buffersSteven Rostedt2010-09-03
| | | | | | | | | | | | | | | | | | | | The trace_seq code that is used to copy data into a buffer to later be able to print was originally taken from the Linux kernel. But the constraints on the kernel are different than what they are in userspace. Since the kernel uses the trace_seq in critical paths, it can not allocate memory during use, so it used a static page buffer. But in userspace, we do not have this constraint, and are allowed to realloc the buffer when needed. There's no reason to fill the buffer when we hit the buffer size, we can simply allocate more memory. The downside to this is that we must call a destructor on the trace_seq structure. All trace_seq's must be initialized with trace_seq_init(), so this patch matched all trace_seq_init()'s with the new function trace_seq_destroy().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a callback wants to hold on to a record, it can then increase the refcount and keep it. This is most likely to happen with the upcoming python plugin. Since the underlying data pages are already refcounted, we can just add a refcount to struct record (rather than having the error checking with the 'locked' member).

* | | parse-events: Fix unaligned accesses while fetching trace valuesFrederic Weisbecker2010-05-24
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Accessing trace values of an 8 size may end up in a segfault on archs that can't deal with misaligned access, which is the case for sparc 64. This is because PERF_SAMPLE_RAW are aligned to 4 and not to 8. Fix this on the macros that get the values of 8 size. This fixes segfaults on perf tools in sparc 64.

* | trace-cmd: Correctly handle arraysIan Munsie2010-05-14
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Taken from a perf patch. I got the OK from Ian Musie to include this under LGPL ] Previously, perf was assuming that an array from an ftrace event was an array of longs, which will not always be the case. Additionally, long_size is not even being initialised, so it would fail to read the data and would erroneously report that the array was filled with zeroes. This patch adds two extra entries into the field structure - arraylen and elementsize, so that the code can easily look them up instead of assuming that the elements are long_size. The element size is currently derived by the size of the entire array and the number of elements within the array. This problem can be demonstrated with: perf record -e raw_syscalls:sys_enter -a sleep 0.1 perf trace Without this patch, output similar to the following is produced: perf-4355 [004] 1871.504685: sys_enter: NR 319 (0, 0, 0, 0, 0, 0) perf-4355 [004] 1871.504723: sys_enter: NR 3 (0, 0, 0, 0, 0, 0) perf-4355 [004] 1871.504733: sys_enter: NR 204 (0, 0, 0, 0, 0, 0) After applying this patch, the output looks like: perf-4355 [004] 1871.504685: sys_enter: NR 319 (10247ac0, ffffffff, 5, ffffffff, 0, 107a80d8) perf-4355 [004] 1871.504723: sys_enter: NR 3 (a, ffb6fcf0, 20, ffffffff, 0, 10112c20) perf-4355 [004] 1871.504733: sys_enter: NR 204 (a, 4, 800, 6, 0, 10112c20) Signed-off-by: Ian Munsie <imunsie@au1.ibm.com> LKML-Reference: <1273730632-21008-3-git-send-email-imunsie@au1.ibm.com> [ Fixed array handling ] Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* parse-events: Fix parenthesis parsing of filtersSteven Rostedt2010-04-01
| | | | | | | | | | | | | The parenthesis filter parsing was a bit broken and needed a rewrite. This redesigns the filter parsing to be a bit more sane when it comes to parenthesis. It lets the parenthesis be treated as what they resolve to be. Funny, the example used by kernelshark failed because of this bug: "next_prio < 100 && (prev_prio > 100 && prev_pid != 0)" Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* trace-cmd: Show lost events if buffer supports itSteven Rostedt2010-04-01
| | | | | | | | | | | If the ring buffer in the kernel sends information via the commit field of the sub buffer header. Than this patch will display where events were lost. If the sub buffer has space and can store the count of dropped events, this patch will show the count as well. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* parse-events: Print raw fields of type long in hexSteven Rostedt2010-03-25
| | | | | | | | When raw fields are printing, check if the field is of type long. Since longs usually store pointers, it makes more sense to print out a hex number for a field declared as long than decimal. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* parse-events: Add raw format for printing eventsSteven Rostedt2010-03-25
| | | | | | | | | | | | | | | | | Add print_raw field to pevent that will cause the pretty_print function to output the entries by their raw data in the fields, and will ignore the print formats. When set, each field will show its data. So instead of this: sched_switch: task swapper:0 [140] (R) ==> trace-cmd:31807 [140] We have: sched_switch: prev_comm=swapper prev_pid=0 prev_prio=140 prev_state=0 next_comm=trace-cmd next_pid=31807 next_prio=140 Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* parse-events: Add hook for plugins to register function handlingSteven Rostedt2010-03-23
| | | | | | | | | | | Sometimes an event may use a helper function inside the print format. Unfortunately, parse-events does not know how to handle these. This patch adds a registration function pevent_register_print_function() That a plugin can use to register how to handle helper functions in the event's print format.

* parse-events: Let plugins be registered before reading eventsSteven Rostedt2010-03-10

* parse-events: Cache last event foundSteven Rostedt2010-02-18
| | | | | | | | | | | | | | | | | | | | | | | | | Code commonly passes around the event id and uses that to find the event. Even if the event was already found, it uses the id to find it later. By caching the last event found by the name or id, and checking that on the next query before searching, saves some time. Running trace-cmd report on 6,000,000 events went from: real 0m41.805s user 0m39.483s sys 0m2.311s to: real 0m39.769s user 0m37.401s sys 0m2.356s About a 4% speed-up.
