perf tools: Make perf aware of tracefs

2015-02-11T15:37:08Z

As tracefs may be mounted instead of debugfs to get to the event directories, have perf know about tracefs, and use that file system over debugfs if it is present.

perf evsel: Remove idx parm from constructor

2013-11-11T18:56:39Z

Most uses of the evsel constructor are followed by a call to perf_evlist__add with an idex of evlist->nr_entries, so make rename the current constructor to perf_evsel__new_idx and remove the need for passing the constructor for the common case. We still need the new_idx variant because the way groups are handled, with evsel->nr_members holding the number of entries in an evlist, partitioning the evlist into sublists inside a single linked list. This asks for a clarifying refactoring, but for now simplify the non parser cases, so that tool writers don't have to bother with evsel idx setting.

perf tests: Move test__open_syscall_event into separate object
