| H A D | evlist.c | 4112eb18 Fri Oct 10 13:55:15 CDT 2014 Arnaldo Carvalho de Melo <acme@redhat.com> perf evlist: Default to syswide target when no thread/cpu maps set
If all a tool wants is to do system wide event monitoring, there is no
more the need to setup thread_map and cpu_map objects, just call
perf_evlist__open() and it will do create one fd per CPU monitoring all
threads.
