Test case 14 runs 'perf stat' command to execute all
tests/attr/test-stat* test cases. They all fail with
a mismatch in sample_type attribute, for example:
running './tests/attr//test-stat-basic'
...
compare
matchng [event:base-stat]
to [event-0-0-4]
...
[sample_type] 0 65536
->FAIL
The reason for the failure is in create_perf_stat_counter()
in file builtin-stat.c. When command 'perf stat record -o -'
is used the value of perf_event_stat.sample_type is not changed.
All other invocations of 'perf stat' change this
member to PERF_SAMPLE_IDENTIFIER (2^16).
None of the test-stat-* tests are invoked with
'perf stat record -o -' and the sample_type comparion fails.
Fix this by changing the expected value for attribute sample_type
in the base_stat file.
