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.
