NAME

       libpfm_intel_icx_unc_m3upi - support for Intel IcelakeX Server M3UPI uncore PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: icx_unc_m3upi[0-3]
       PMU desc: Intel IcelakeX M3UPI uncore PMU

DESCRIPTION

       The  library  supports  the Intel IcelakeX M3UPI (Mesh to UPI) uncore PMU.  Each M3UPI PMU
       implements 4 generic counters.

MODIFIERS

       The following modifiers are supported on Intel IcelakeX M3UPI 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 IRP 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.
