From 52502bf201a85b5b51a384037a002d0b39093df0 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Wed, 31 Oct 2012 15:52:47 +0100 Subject: 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 Cc: Arnaldo Carvalho de Melo Cc: Corey Ashford Cc: Frederic Weisbecker Cc: Ingo Molnar Cc: Paul Mackerras Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/20121031145247.GB1027@krava.brq.redhat.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/perf.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'tools/perf/perf.c') diff --git a/tools/perf/perf.c b/tools/perf/perf.c index e9683738d89f..a0ae2902f9c9 100644 --- a/tools/perf/perf.c +++ b/tools/perf/perf.c @@ -484,6 +484,8 @@ int main(int argc, const char **argv) } cmd = argv[0]; + test_attr__init(); + /* * We use PATH to find perf commands, but we prepend some higher * precedence paths: the "--exec-path" option, the PERF_EXEC_PATH -- cgit v1.2.1
