perf tests: Add framework for automated perf_event_attr tests
The idea is run perf session with kidnapping sys_perf_event_open function. For each sys_perf_event_open call we store the perf_event_attr data to the file to be checked later against what we expect. You can run this by: $ python ./tests/attr.py -d ./tests/attr/ -p ./perf -v v2 changes: - preserve errno value in the hook Signed-off-by: Jiri Olsa <jolsa@redhat.com> Cc: Arnaldo Carvalho de Melo <acme@ghostprotocols.net> Cc: Corey Ashford <cjashfor@linux.vnet.ibm.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/20121031145247.GB1027@krava.brq.redhat.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
