Description of problem:
[ANCK-5.10][倚天][aarch64][nightly]perf_event_tests测试套下的openmp_test用例失败， Count=1918M, expected roughly 1280M Error!  Count too low! 该用例在倚天机型执行fail，kunpeng机型执行pass


详细测试日志如下：
# ./tests/openmp/openmp_test
Testing OpenMP behavior

Note!!! Inherit only works if the event is created
before the fork happens!  OpenMP creates thread pools
so if you create the event after the thread pools hae been
created it may be too late and you won't get child events!
