* perf lock: Account for lock average wait timeDavidlohr Bueso2013-10-092-2/+10
| | | | | | | | | | | | | | | | | | | | While perf-lock currently reports both the total wait time and the number of contentions, it doesn't explicitly show the average wait time. Having this value immediately in the report can be quite useful when looking into performance issues. Furthermore, allowing report to sort by averages is another handy feature to have - and thus do not only print the value, but add it to the lock_stat structure.

* perf lock: Redo __cmd_reportDavidlohr Bueso2013-10-091-32/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This function should be straightforward, and we can remove some trivial logic by moving the functionality of read_events() into __cmd_report() - thus allowing a new session to be properly deleted. Since the 'info' subcommand also needs to process the recorded events, add a 'display_info' flag to differentiate between report and info commands. Furthermore, this patch also calls perf_session__has_traces(), making sure that we don't compare apples and oranges, fixing a segfault when using an perf.data file generated by a different subcommand. ie: ./perf mem record sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.017 MB perf.data (~724 samples) ] ./perf lock report Segmentation fault (core dumped) Signed-off-by: Davidlohr Bueso <davidlohr@hp.com> Cc: Aswin Chandramouleeswaran <aswin@hp.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Hitoshi Mitake <mitake@dcl.info.waseda.ac.jp> Cc: Ingo Molnar <mingo@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/1378693159-8747-5-git-send-email-davidlohr@hp.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
