NAME

       libpfm_intel_icx_unc_m2pcie - support for Intel IcelakeX Server M2PCIE uncore PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: icx_unc_m2pcie[0-2]
       PMU desc: Intel IcelakeX M2PCIE uncore PMU

DESCRIPTION

       The  library  supports  the Intel IcelakeX M2PCIE (Mesh to IIO) uncore PMU.  Each M2PCIE PMU implements 4
       generic counters.

MODIFIERS

       The following modifiers are supported on Intel IcelakeX M2PCIE 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 M2PCIE
              clockticks 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.
