perf evlist: Fix type for references to data_head/tail

2015-04-10T14:29:20Z

The data_head and data_tail fields are defined as __u64 in linux/perf_event.h, but perf userspace uses int and unsigned int. Convert all references to u64 for consistency.

perf evlist: Return the first evsel with an invalid filter in apply_filters()

2015-03-26T13:52:28Z

Use of a bad filter currently generates the message: Error: failed to set filter with 22 (Invalid argument) Add the event name to make it clear to which event the filter failed to apply: Error: Failed to set filter "foo" on event sched:sg_lb_stats: 22: Invalid argument To test it use something like: # perf record -e sched:sched_switch -e sched:*fork --filter parent_pid==1 -e sched:*wait* --filter bla usleep 1 Error: failed to set filter "bla" on event sched:sched_stat_iowait with 22 (Invalid argument) # Based-on-a-patch-by: David Ahern Acked-by: David Ahern Cc: Adrian Hunter Cc: Borislav Petkov Cc: Don Zickus Cc: Frederic Weisbecker Cc: Jiri Olsa Cc: Namhyung Kim Cc: Stephane Eranian Link: http://lkml.kernel.org/n/tip-d7gq2fjvaecozp9o2i0siifu@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf top: Fix SIGBUS on sparc64

2015-02-25T20:37:44Z

perf-top is terminating due to SIGBUS on sparc64. git bisect points to: commit 82396986032915c1572bfb74b224fcc2e4e8ba7c Author: Arnaldo Carvalho de Melo Date: Mon Sep 8 13:26:35 2014 -0300 perf evlist: Refcount mmaps We need to know how many fds are using a perf mmap via PERF_EVENT_IOC_SET_OUTPUT, so that we can know when to ditch an mmap, refcount it. This commit added 'int refcnt' to struct perf_mmap and the addition makes the event_copy element no longer 8-byte aligned. Fix by adding __attribute__((aligned(8))) to the event_copy struct member.

perf evlist: Adopt events_stats from perf_session

2015-02-23T01:22:57Z

For tools that don't deal with perf.data files, thus do not need to use perf_session.

perf evlist: Introduce set_filter_pids method

2015-02-23T01:21:27Z

perf evlist: Introduce set_filter_pid method

2015-02-23T01:14:25Z

To filter out events for a certain pid, for instance, when tracing system wide, so that the tracer itself doesn't creates an event loop.

perf evlist: Add missing 'struct option' forward declaration

2014-10-17T15:16:00Z

It was being found, by chance, because evsel.h needlessly includes util/cgroup.h, which will be sorted out in a following patch.
