| 2019-04-01 | tools lib traceevent: Add more debugging to see various internal ring buffer ↵ | Steven Rostedt (Red Hat) | 1 | -0/+49 | |
| entries When trace-cmd report --debug is set, show the internal ring buffer entries like time-extends and padding. This requires adding new kbuffer API to retrieve these items.

| 2017-02-13 | tools lib traceevent: Initialize lenght on OLD_RING_BUFFER_TYPE_TIME_STAMP | Steven Rostedt (VMware) | 1 | -0/+1 | |
| A undefined value was being used for the OLD_RING_BUFFER_TYPE_TIME_STAMP case entry, as the 'length' variable was not being initialized, fix it. Caught by the reporter when building tools/perf/ using clang, which emmitted this warning: kbuffer-parse.c:312:7: warning: variable 'length' is used uninitialized whenever switch case is taken [-Wsometimes-uninitialized] case OLD_RINGBUF_TYPE_TIME_EXTEND: ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ kbuffer-parse.c:339:29: note: uninitialized use occurs here kbuf->next = kbuf->index + length; ^~~~~~ kbuffer-parse.c:297:21: note: initialize the variable 'length' to silence this warning unsigned int length; ^ = 0 Reported-by: Arnaldo Carvalho de Melo <[email protected]> Signed-off-by: Steven Rostedt <[email protected]> Cc: Adrian Hunter <[email protected]> Cc: David Ahern <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: Namhyung Kim <[email protected]> Cc: Wang Nan <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]> | |||||
| 2016-10-05 | tools lib traceevent: Fix kbuffer_read_at_offset() | Namhyung Kim | 1 | -0/+1 | |
| When it's called with an offset less than or equal to the first event, it'll return a garbage value since the data is not initialized.

| 2015-03-24 | tools lib traceevent: Add way to find sub buffer boundary | Steven Rostedt (Red Hat) | 1 | -0/+11 | |
| For debugging purposes, it may be helpful for the kbuffer library to flag when crossing a sub buffer.

| 2015-03-24 | tools lib traceevent kbuffer: Remove extra update to data pointer in PADDING | Steven Rostedt (Red Hat) | 1 | -1/+0 | |
| When a event PADDING is hit (a deleted event that is still in the ring buffer), translate_data() sets the length of the padding and also updates the data pointer which is passed back to the caller. This is unneeded because the caller also updates the data pointer with the passed back length. translate_data() should not update the pointer, only set the length.

| 2013-07-12 | tools lib traceevent: Port kbuffer parser routines | Namhyung Kim | 1 | -0/+732 | |
| kbuffer code is for parsing ftrace ring-buffer binary data and used for trace-cmd. Move the code here in order to be used more widely.
