NAME

       libpfm_intel_icx_unc_m2m - support for Intel Icelake X Server Mesh to Memory (M2M)  uncore PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: icx_unc_m2m[0-1]
       PMU desc: Intel Icelake X Server M2M uncore PMU

DESCRIPTION

       The library supports the Intel Icelake X Server Mesh to Memory (M2M) uncore PMU.

MODIFIERS

       The following modifiers are supported on Intel Icelake X server M2M 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 M2M 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].  i Invert the threshold (t) test from strictly
              greater than to less or equal to. This is a boolean modifier.
