perf session: Pass evsel in event_ops->sample()

2011-03-23T22:28:58Z

Resolving the sample->id to an evsel since the most advanced tools, report and annotate, and the others will too when they evolve to properly support multi-event perf.data files. Good also because it does an extra validation, checking that the ID is valid when present. When that is not the case, the overhead is just a branch + function call (perf_evlist__id2evsel).

perf tool: Fix gcc 4.6.0 issues

2011-02-07T14:41:41Z

GCC 4.6.0 in Fedora rawhide turned up some compile errors in tools/perf due to the -Werror=unused-but-set-variable flag. I've gone through and annotated some of the assignments that had side effects (ie: return value from a function) with the __used annotation, and in some cases, just removed unused code. In a few cases, we were assigning something useful, but not using it in later parts of the function. kyle@dreadnought:~/src% gcc --version gcc (GCC) 4.6.0 20110122 (Red Hat 4.6.0-0.3) Cc: Ingo Molnar LKML-Reference: <20110124161304.GK27353@bombadil.infradead.org> Signed-off-by: Kyle McMartin [ committer note: Fixed up the annotation fixes, as that code moved recently ] Signed-off-by: Arnaldo Carvalho de Melo

perf: Rename 'perf trace' to 'perf script'

2010-11-16T18:37:44Z

Free the perf trace name space and rename the trace to 'script' which is a better match for the scripting engine. Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner

perf scripts python: Give field dict to unhandled callback

2010-06-01T09:12:35Z

trace_unhandled() callback does not allow to access event fields, this patch resolves the problem. It can also been used as a more pythonic and flexible way for script writters to demux event types This will for example greatly simplify pytimechart event demux.

perf/trace/scripting: don't show script start/stop messages by default

2010-05-10T22:50:59Z

Only print the script start/stop messages in verbose mode - users normally don't care and it just clutters up the output. Cc: Frédéric Weisbecker Cc: Ingo Molnar LKML-Reference: <1273466820-9330-7-git-send-email-tzanussi@gmail.com> Signed-off-by: Tom Zanussi Signed-off-by: Arnaldo Carvalho de Melo

perf/scripts: Tuple was set from long in both branches in python_process_event()

2010-04-02T19:32:16Z

This is a fix to the signed/unsigned field handling in the Python scripting engine, based on a patch from Roel Kluin. Basically, Python wants to use a PyInt (which is internally a long) if it can i.e. if the value will fit into that type. If not, it stores it into a PyLong, which isn't actually a long, but an arbitrary-precision integer variable. The code below is similar to to what Python does internally, and it seems to work as expected on the x86 and x86_64 sytems I tested it on.

perf/scripts: Remove unnecessary PyTuple resizes

2010-02-25T03:07:49Z

If we know the size of a tuple in advance, there's no need to resize it - start out with the known size in the first place.
