NAME

       libpfm_intel_skx_unc_m3upi - support for Intel Skylake X Server M3UPI uncore PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: skx_unc_m3upi[0-2]
       PMU desc: Intel Skylake X server M3UPI uncore PMU

DESCRIPTION

       The library supports the Intel Skylake X server M3UPI uncore PMU.

MODIFIERS

       The following modifiers are supported on Intel Skylake X server M3UQI  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 M3UPI
              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
