perf tools: Fixup mmap event consumption

2013-10-28T19:06:00Z

The tail position of the event buffer should only be modified after actually use that event. If not the event buffer could be invalid before use, and segment fault occurs when invoking perf top -G.

perf tools: Add attr->mmap2 support

2013-09-11T13:09:32Z

This patch adds support for the new PERF_RECORD_MMAP2 record type exposed by the kernel. This is an extended PERF_RECORD_MMAP record. It adds for each file-backed mapping the device major, minor number and the inode number and generation. This triplet uniquely identifies the source of a file-backed mapping. It can be used to detect identical virtual mappings between processes, for instance. The patch will prefer MMAP2 over MMAP.

perf evlist: Add want_signal parameter to perf_evlist__prepare_workload()

perf evlist: Do not pass struct record_opts to perf_evlist__prepare_workload()

2013-03-15T16:06:02Z

Since it's only used for checking ->pipe_output, we can pass the result directly. Now the perf_evlist__prepare_workload() don't have a dependency of struct perf_record_opts, it can be called from other places like perf stat.

perf evlist: Pass struct perf_target to perf_evlist__prepare_workload()

2013-03-15T16:06:02Z

It's a preparation step of removing @opts arg from the function so that it can be used more widely.

perf evlist: Remove cpus and threads arguments from perf_evlist__new()

2013-03-15T16:06:01Z

It's almost always used with NULL for both arguments. Get rid of the arguments from the signature and use perf_evlist__set_maps() if needed.
