perf tools: Use tid for finding thread

2014-05-12T09:09:50Z

I believe that passing pid (instead of tid) as the 3rd arg of the machine__find*_thread() was to find a main thread so that it can search proper map group for symbols. However with the map sharing patch applied, it now can do it in any thread. It fixes a bug when each thread has different name, it only reports a main thread for samples in other threads.

tools: Consolidate types.h

2014-05-01T19:22:39Z

Combine all definitions into a common tools/include/linux/types.h and kill the wild growth elsewhere. Move DECLARE_BITMAP to its proper bitmap.h header.

perf tools: Fix double free in perf test 21 (code-reading.c)

2014-04-15T11:57:14Z

perf_evlist__delete() deletes attached cpu and thread maps but the test is still using them, so remove them from the evlist before deleting it. Signed-off-by: Adrian Hunter Link: http://lkml.kernel.org/r/53465E3E.8070201@intel.com Signed-off-by: Jiri Olsa

perf evlist: Auto unmap on destructor

2014-01-13T13:06:22Z

Removing further boilerplate after making sure perf_evlist__munmap can be called multiple times for the same evlist.

perf evlist: Close fds on destructor

2014-01-13T13:06:22Z

Since it is safe to call perf_evlist__close() multiple times, autoclose it and remove the calls to the close from existing tools, reducing the tooling boilerplate.

perf evlist: Move destruction of maps to evlist destructor

2014-01-13T13:06:21Z

Instead of requiring tools to do an extra destructor call just before calling perf_evlist__delete.

perf tools: Rename 'perf_record_opts' to 'record_opts

2013-12-19T17:43:45Z

Reduce typing, functions use class__method convention, so unlikely to clash with other libraries. This actually was discussed in the "Link:" referenced message below.

perf record: Synthesize non-exec MMAP records when --data used

2013-11-11T18:56:39Z

When perf_event_attr.mmap_data is set the kernel will generate PERF_RECORD_MMAP events when non-exec (data, SysV mem) mmaps are created, so we need to synthesize from /proc/pid/maps for existing threads, as we do for exec mmaps. Right now just 'perf record' does it, but any other tool that uses perf_event__synthesize_thread(s|map) can request it.

perf tools: Add time argument on COMM setting

2013-11-04T14:57:06Z

This way we can later delimit a lifecycle for the COMM and map a hist to a precise COMM:timeslice couple. PERF_RECORD_COMM and PERF_RECORD_FORK events that don't have PERF_SAMPLE_TIME samples can only send 0 value as a timestamp and thus should overwrite any previous COMM on a given thread because there is no sensible way to keep track of all the comms lifecycles in a thread without time informations.
