NAME¶
libpfm_intel_ivbep_unc_r2pcie - support for Intel Ivy Bridge-EP R2 PCIe uncore
PMU
SYNOPSIS¶
#include <perfmon/pfmlib.h>
PMU name: ivbep_unc_r2pcie
PMU desc: Intel Ivy Bridge-EP R2 PCIe uncore PMU
DESCRIPTION¶
The library supports the Intel Ivy Bridge R2 PCIe uncore PMU. This PMU model
only exists on Ivy Bridge model 62.
MODIFIERS¶
The following modifiers are supported on Intel Ivy Bridge R2PCIe 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 R2PCIe 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 [0:15].
