NAME

       libpfm_intel_hswep_unc_r3qpi - support for Intel Haswell-EP R3QPI uncore PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: hswep_unc_r3qpi[0-2]
       PMU desc: Intel Haswell-EP R3QPI uncore PMU

DESCRIPTION

       The library supports the Intel Haswell R3QPI uncore PMU.  This PMU model only exists on Haswell model 63.

MODIFIERS

       The following modifiers are supported on Intel Haswell R3PQI  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 R3QPI
              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].

       i      Invert  the  meaning  of the threshold or edge filter. If set, the event counts when strictly less
              than N occurrences occur per cycle if threshold is set to N. When invert is  set,  then  threshold
              must  be set to non-zero value. If set, the event counts when the event transitions from occurring
              to not occurring (falling edge) when edge detection is set. This is a boolean modifier
