perf tools: Fix -x/--exclude-other option for report command

2013-07-08T20:38:53Z

Currently we have symbol_conf.exclude_other being set as true every time so the -x/--exclude-other has nothing to do. Also we have no way to see the data with symbol_conf.exclude_other being false which is useful sometimes. Fixing it by making symbol_conf.exclude_other false by default. 1) Example without -x option: $ perf report -i perf.data.delete -p perf_session__delete -s parent + 99.91% [other] + 0.08% perf_session__delete + 0.00% perf_session__delete_dead_threads + 0.00% perf_session__delete_threads 2) Example with -x option: $ ./perf report -i perf.data.delete -p perf_session__delete -s parent -x + 96.22% perf_session__delete + 1.89% perf_session__delete_dead_threads + 1.89% perf_session__delete_threads In Example 1) we get the sorted out data together with the rest "[other]". This could help us estimate how much time we spent in the sorted data. In Example 2) the total is just the sorted data.

perf report: Add --no-demangle option

2013-03-26T19:38:21Z

It's sometimes useful to see undemangled raw symbol name for example other tools using the perf output to do manipulation of binaries.

perf symbols: Mark vmlinux filename as allocated

2013-01-24T19:40:32Z

Needs to be marked allocated so memory can be freed when dso is deleted. Signed-off-by: David Ahern Link: http://lkml.kernel.org/r/1358185650-90848-1-git-send-email-dsahern@gmail.com Signed-off-by: Arnaldo Carvalho de Melo

perf symbols: Generalize filter in __fprintf_buildid methods

2012-12-09T11:46:07Z

We had that 'with_hits' filter to show just the build ids for DSOs that had samples, make that generic so that we can use it in the upcoming buildid-cache --missing feature, to show just the build ids that are not in the cache.

This time out of map.[ch] mostly, just code move plus a buch of 'self' removal, using machine or machines instead.

perf tools: Move dso_* related functions into dso object

2012-10-29T13:37:25Z

Moving dso_* related functions into dso object. Keeping symbol loading related functions still in the symbol object as it seems more convenient.
