NAME

       libpfm_intel_ivbep_unc_ha - support for Intel Ivy Bridge-EP Home Agent (HA) uncore PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: ivbep_unc_ha0, ivbep_unc_ha1
       PMU desc: Intel Ivy Bridge-EP HA uncore PMU

DESCRIPTION

       The  library supports the Intel Ivy Bridge Home Agent (HA) uncore PMU.  This PMU model only exists on Ivy
       Bridge model 62.

MODIFIERS

       The following modifiers are supported on Intel Ivy Bridge HA 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 HA  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].
