perf hists: Stop using 'self' for struct hist_entry

2012-01-06T17:42:52Z

Stop using this python/OOP convention, doesn't really helps. Will do more from time to time till we get it cleaned up in all of /perf.

Merge branch 'perf/urgent' into perf/core

2011-12-06T05:43:49Z

Merge reason: Add these cherry-picked commits so that future changes on perf/core don't conflict. Signed-off-by: Ingo Molnar

perf symbols: Add nr_events to symbol_conf

2011-11-28T12:37:11Z

Since symbol__alloc_hists need it, to avoid passing it around in many functions have it in the symbol_conf struct.

perf python: Fix undefined symbol problem

2011-11-16T12:02:26Z

Recently we made perf_evsel__init call hists__init, which broke the perf python binding: [root@emilia linux]# ./tools/perf/python/twatch.py Traceback (most recent call last): File "./tools/perf/python/twatch.py", line 16, in import perf ImportError: /home/acme/git/build/perf/python/perf.so: undefined symbol: hists__init Fix it by moving the hists__init function to its only caller, evsel.c. This way we avoid dragging in other parts of tools/perf/util/ to the perf python binding.

perf hists browser: Warn about lost events

2011-11-02T14:27:23Z

Just like the old perf top --tui and the --stdio version. But because we have the initial menu to choose which event to show in a session with multiple events we can see how many chunks were lost in each of the event types, clarifying which events are being affected the most.

perf ui browser: Use libslang to read keys

2011-10-20T18:59:15Z

Just another step in stopping the use of libnewt in perf. Cc: David Ahern Cc: Frederic Weisbecker Cc: Mike Galbraith Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Stephane Eranian Link: http://lkml.kernel.org/n/tip-uy6s534uqxq8tenh6s3k8ocj@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf hists: Move the dso and thread filters from hist_browser

2011-10-19T11:28:19Z

Since with dynamic addition of new hist entries we need to apply those filters as we merge new batches of hist_entry instances, for instance in perf top.

perf hists: Don't format the percentage on hist_entry__snprintf

2011-10-18T19:03:08Z

We can't have color correctly set there because in libslang (and in a future GUI) the colors must be set on a separate function call, so move that part to a separate function and make the stdio fprintf function call it.

perf top: Honour --hide_{user,kernel}_symbols and the 'U' hotkey

2011-10-17T11:05:04Z

The new decay routine (__hists__decay_entries) wasn't being passed the toggles, fix it.

perf top: Remove entries from entries_collapsed on decay

2011-10-13T13:29:17Z

We were removing only when using a --sort order that needs collapsing, while we also use it in the threaded case, causing memory corruption because we were scribbling freed hist entries, oops.
