The following functions are related to hardware counter overflow profiling:
collector_not_program_related – The counter does not relate to the program.
collector_hwcs_out_of_range – The counter appears to have exceeded the overflow value without generating an overflow signal. The value is recorded and the counter reset.
collector_hwcs_frozen – The counter appears to have exceeded the overflow value and been halted but the overflow signal appears to be lost. The value is recorded and the counter reset.
collector_hwc_ABORT – Reading the hardware counters has failed, typically when a privileged process has taken control of the counters, resulting in the termination of hardware counter collection.
collector_record_counter – The counts accumulated while handling and recording hardware counter events, partially accounting for hardware counter overflow profiling overhead. If this value corresponds to a significant fraction of the <Total> count, a larger overflow interval (that is, a lower resolution configuration) is recommended.
