perf tools: Fix crash on synthesizing the unit

2018-11-12T16:37:49Z

Adam reported a record command crash for simple session like: $ perf record -e cpu-clock ls with following backtrace: Program received signal SIGSEGV, Segmentation fault. 3543 ev = event_update_event__new(size + 1, PERF_EVENT_UPDATE__UNIT, evsel->id[0]); (gdb) bt #0 perf_event__synthesize_event_update_unit #1 0x000000000051e469 in perf_event__synthesize_extra_attr #2 0x00000000004445cb in record__synthesize #3 0x0000000000444bc5 in __cmd_record ... We synthesize an update event that needs to touch the evsel id array, which is not defined at that time. Fix this by forcing the id allocation for events with their unit defined. Reflecting possible read_format ID bit in the attr tests.

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 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.
