perf tests: Fix task exit test setting maps

2015-09-15T14:03:58+00:00

The test titled "Test number of exit event of a simple workload" was
setting cpu/thread maps directly.  Make it use the proper function
perf_evlist__set_maps() especially now that it also propagates the maps.

perf evlist: Introduce poll method for common code idiom

2014-09-25T19:46:55+00:00

Since we have access two evlist members in all these poll calls, provide
a helper.

This will also help to make the patch introducing the pollfd class more
clear, as the evlist specific uses will be hiden away
perf_evlist__poll().

perf test: Use strerror_r instead of strerror

2014-08-15T16:07:28+00:00

Use strerror_r instead of strerror in error messages for thread-safety.

perf evlist: Auto unmap on destructor

2014-01-13T13:06:22+00:00

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

perf evlist: Close fds on destructor

2014-01-13T13:06:22+00:00

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

2014-01-13T13:06:21+00:00

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

2014-01-13T13:06:21+00:00

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

perf target: Shorten perf_target to target

2013-11-12T19:51:03+00:00

Getting unwieldly long, for this app domain should be descriptive enough
and the use of __ to separate the class from the method names should
help with avoiding clashes with other code bases.

perf tools: Fixup mmap event consumption

2013-10-28T19:06:00+00:00

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.
