I have taken the following commits from Jiri Olsa's branch perf/attr_test to work on a fix. Commit-id 070b9644981e perf tests attr: Do not store failed events c9666c26ead0 perf tests attr: Make compare_data global 10eb9496d1c3 perf tests attr: Fix compare logic 4ba31b633fab perf tests attr: Add 1s for exclude_kernel .. ede0b0a2e007 perf tests attr: Fix no-delay test I have then added 3 new fixes Thomas Richter (3): perf: fix incorrect sample_type value for perf stat tests perf: fix exit code check in test case execution perf: fix perf test case 14 I can test these changes only on s390. With these changes some test-stat-xxx tests run fine. How to handle test cases currently unsupported on a platform? For example test-stat-default issues a setup for PERF_TYPE_HARDWARE / PERF_COUNT_HW_STALLED_CYCLES_BACKEND which is not supported on s390. The perf_event_open() system call fails and no event-00-07--1 file is created. The compare of the test result then fails because attr.py has nothing to check against. We could test if an event file exists and if not report an unsupported test. Is this a good idea? Any other proposals? Right now I have commented out these subtests in my environment. -- 2.9.3 -- To unsubscribe from this list: send the line "unsubscribe linux-s390" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
