perf tests attr: Fix task term values

2017-10-02T16:59:18Z

The perf_event_attr::task is 1 by default for first (tracking) event in the session. Setting task=1 as default and adding task=0 for cases that need it.

perf tests attr: Fix precise_ip setup

2017-07-19T02:14:21Z

We have a test to detect to highest precise possible, so test can't just predict precise_ip value.

perf tests attr: Fix sample_period setup

2017-07-19T02:14:20Z

The final period can differ from what user specifies on command line due to the perf_event_max_sample_rate sysctl setup. Thus we can't predixt the sample_period value any more.

perf tests attr: Add 1s for exclude_kernel and task base bits

2017-07-19T02:14:17Z

There's an event open fallback which set exclude_kernel=1 in case use does not have enough privileges. Adding both 0|1 for this attribute, because we don't know what value it is.

perf tests: Fix attr tests size values to cope with machine state on interrupt ABI changes

2014-12-09T14:02:43Z

Following change adjusted 'struct perf_event_attr', but let the attr test's sizes untouched: 60e2364e60e8 perf: Add ability to sample machine state on interrupt [jolsa@krava perf]$ ./perf test attr -vv --- start --- test child forked, pid 9719 running './tests/attr/test-stat-group1' 'PERF_TEST_ATTR=/tmp/tmp4drvul ./perf stat -o /tmp/tmp4drvul/perf.data -e '{cycles,instructions}' kill >/dev/null 2>&1' ret 1 expected size=96, got 104 FAILED './tests/attr/test-stat-group1' - match failure Adjusting test size values for attr test.

perf tests: Update attr test with PERF_FLAG_FD_CLOEXEC flag

2014-07-18T07:09:53Z

We not support PERF_FLAG_FD_CLOEXEC flag, updating attr tests accordingly.

perf tests: Fix exclude_guest|exclude_host checking for attr tests

2013-05-29T12:15:19Z

We have a one of the event open fallback case in __perf_evsel__open where we zero exclude_guest|exclude_host fields. This means there's no way for attr tests to find out what's the right value for those fields, so we need to check for both 0 and 1. Luckily we still have other event parsing tests for those fields.

perf tests: Make attr script test event cpu

2013-03-15T16:06:00Z

Make attr script to check for 'cpu' when testing event properties. This will allow us to check the '-C X' option for both record and stat commands.

perf evsel: No need to always ask for PERF_FORMAT_TOTAL_TIME_{ENABLED,RUNNING}

2012-12-11T20:17:17Z

This is needed, so far, just in 'perf stat', to scale counters, so don't unconditionally ask for them in the perf_evsel__config() method.
