libpfm_intel_ivbep_unc_irp - support for Intel Ivy Bridge-EP IRP
uncore PMU
#include <perfmon/pfmlib.h>
PMU name: ivbep_unc_irp
PMU desc: Intel Ivy Bridge-EP IRP uncore PMU
The library supports the Intel Ivy Bridge uncore PMU. This PMU model
only exists on Ivy Bridge model 62.
The following modifiers are supported on Intel Ivy Bridge IRP uncore
PMU:
e Enable edge detection, i.e., count only when there is a state
transition from no occurrence of the event to at least one
occurrence. This modifier must be combined with a threshold
modifier (t) with a value greater or equal to one. This is a
boolean modifier.
t Set the threshold value. When set to a non-zero value, the
counter counts the number of cycles in which the number of
occurrences of the event is greater or equal to the threshold.
This is an integer modifier with values in the range [0:255].
