perf tests: Adjust some message log levels to help diagnosing problems in attr tests
Now we'll see the command being run and if it fails, the fields that had unexpected values and the expected values, example testing a problem in the next patch: # perf test -v 13 13: struct perf_event_attr setup : --- start --- SNIP running 'PERF_TEST_ATTR=/tmp/tmpDNIE6M /home/acme/bin/perf record -o /tmp/tmpDNIE6M/perf.data --group -e cycles,instructions kill >/dev/null 2>&1' ret 0 running 'PERF_TEST_ATTR=/tmp/tmpV5lKro /home/acme/bin/perf stat -o /tmp/tmpV5lKro/perf.data -dd kill >/dev/null 2>&1' ret 1 expected config=3, got 65540 expected exclude_guest=1, got 0 FAILED '/home/acme/libexec/perf-core/tests/attr/test-stat-detailed-2' - match failure ---- end ---- struct perf_event_attr setup: FAILED! # While in the past we would see at the '-v' level many more messages for the fields that matched, something we may want to see only in the '-vv' log level. Keeping the 'running' messages so that we can see the tools tests that succeeded so that we can compare it to the one that failed, helping pinpointing the command line switch combo that leads to the problem.
