perf record: Rename --no-delay to --no-buffering

2014-01-14T20:57:04Z

That is how the option summary describes it and so that we can free --delay to replace --initial-delay and then be consistent with stat's --delay equivalent option.

perf evlist: Auto unmap on destructor

2014-01-13T13:06:22Z

Removing further boilerplate after making sure perf_evlist__munmap can be called multiple times for the same evlist.

perf evlist: Close fds on destructor

2014-01-13T13:06:22Z

Since it is safe to call perf_evlist__close() multiple times, autoclose it and remove the calls to the close from existing tools, reducing the tooling boilerplate.

perf evlist: Move destruction of maps to evlist destructor

2014-01-13T13:06:21Z

Instead of requiring tools to do an extra destructor call just before calling perf_evlist__delete.

perf evlist: Move the SIGUSR1 error reporting logic to prepare_workload

2014-01-13T13:06:21Z

So that we have the boilerplate in the preparation method, instead of open coded in tools wanting the reporting when the exec fails.

perf tools: Rename 'perf_record_opts' to 'record_opts

2013-12-19T17:43:45Z

Reduce typing, functions use class__method convention, so unlikely to clash with other libraries. This actually was discussed in the "Link:" referenced message below.

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 evlist: Introduce perf_evlist__new_default function

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.
