Ok, so I applied this to my local perf/core branch with a few changes, namely to move 24/25 to after 5/25 so that I could do, for each subsequent tests: $ make -j8 -C tools/perf/ O=/home/acme/git/build/perf install $ perf test -v perf_event_attr And see if each one passed. So at the end I changed /home/acme/libexec/perf-core/tests/attr/base-record flipping "watermark=0" to "watermark=1" and got: [root@sandy ~]# perf test perf_event_attr 13: struct perf_event_attr setup :FAILED '/home/acme/libexec/perf-core/tests/attr/test-record-count' - match failure FAILED! [root@sandy ~]# But I wanted it to show _what_ didn't match, so I tried: [root@sandy ~]# perf test -v perf_event_attr 13: struct perf_event_attr setup : --- start --- running '/home/acme/libexec/perf-core/tests/attr/test-record-count' FAILED '/home/acme/libexec/perf-core/tests/attr/test-record-count' - match failure ---- end ---- struct perf_event_attr setup: FAILED! [root@sandy ~]# Also is there a strict need for setting PERF_TEST_ATTR? I thought that if it found the /home/acme/libexec/perf-core/tests/attr/ dirs it would test it, but haven't dug deep, care to ellaborate here? Ah, I just pushed perf/core with this patchset, thanks! - Arnaldo -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
