perf stat: Use xyarray for cpu evsel counts

2015-06-26T14:19:19Z

perf tools: Add reference counting for thread_map object

2015-06-25T18:15:50Z

Adding reference counting for thread_map object, so it could be easily shared among other objects. Using thread_map__put instead thread_map__delete and making thread_map__delete static.

perf thread_map: Don't access the array entries directly

2015-06-23T21:21:44Z

Instead provide a method to set the array entries, and another to access the contents.

perf tests: Add test for make install with prefix

2015-06-22T14:24:05Z

Lukas Wunner reported issue (and fix[1]) with 'make install prefix=...'. Adding automated test for this, so it wouldn't happen again.

perf tests: Add testing for Makefile.perf

2015-06-22T14:21:57Z

Currently we test only builds through top level Makefile, but seems like there's a bunch of users using Makefile.perf directly. Changing the make suite to be run for Makefile.perf as well. It takes now considerable amount of time, but hopefully we catch more issues. Also fixing the output indentation for make_kernelsrc and make_kernelsrc_tools tests.

perf tools: Configurable per thread proc map processing time out

2015-06-19T21:27:13Z

The time out to limit the individual proc map processing was hard code to 500ms. This patch introduce a new option --proc-map-timeout to make the time limit configurable.
