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.
