perf evsel: Introduce is_group_member method

2012-11-14T19:53:45Z

To clarify what is being tested, instead of assuming that evsel->leader == NULL means either an 'isolated' evsel or a 'group leader'.

perf tools: Omit group members from perf_evlist__disable/enable

2012-11-14T19:52:15Z

There's no need to disable/enable ordinary group member events, because they are initialy enabled and get scheduled by the leader.

perf tools: Fix attributes for '{}' defined event groups

2012-11-14T19:51:50Z

Fixing events attributes for groups defined via '{}'. Currently 'enable_on_exec' attribute in record command and both 'disabled ' and 'enable_on_exec' attributes in stat command are set based on the 'group' option. This eliminates proper setup for '{}' defined groups as they don't set 'group' option. Making above attributes values based on the 'evsel->leader' as this is common to both group definition. Moving perf_evlist__set_leader call within builtin-record ahead perf_evlist__config_attrs call, because the latter needs possible group leader links in place.

perf tools: Have the page size value available for all tools

2012-10-06T19:33:14Z

Its such a common need that we might as well have a global with that value.

perf evlist: Remove some unused methods

2012-10-03T14:52:07Z

Those were introduced in a previous attempt at implementing 'trace', but are not being used anywhere, ditch them.

perf evlist: Introduce add_newtp method

2012-10-03T14:41:22Z

To reduce the boilerplate of creating and adding a new tracepoint to an evlist.

perf evlist: Introduce set_filter() method

2012-09-26T18:08:43Z

To apply a filter to all the evsels in an evlist.

perf evlist: Renane set_filters method to apply_filters

2012-09-26T17:45:16Z

Because that is what it really does, i.e. it applies the filters that were parsed from the command line and stashed into the evsels they refer to. We'll need the set_filter method name to actually apply a filter to all the evsels in an evlist, for instance, to ask that a syswide tracer doesn't trace itself.

perf evsel: Know if byte swap is needed

2012-09-26T15:48:18Z

Instead of passing it around for parsing as an explicit parameter, will help with reading tracepoint fields when not using a perf session or pevent structure, i.e. for non perf.data centered workflows.

perf tools: Allow handling a NULL cpu_map as meaning "all cpus"

2012-09-26T15:41:14Z

Or one with cpu_map->map[0] == -1. Reducing the boilerplate in setting up an evlist by nor requiring a cpu_map to be created at all.
