NAME

       libpfm_intel_icx_unc_irp - support for Intel IcelakeX Server IRP uncore PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: icx_unc_irp[0-5]
       PMU desc: Intel IcelakeX IRP uncore PMU

DESCRIPTION

       The  library  supports the Intel IcelakeX IRP (IIO Ring Port) uncore PMU. There is one IRP per IIO.  Each
       IRP PMU implements 4 generic counters.

MODIFIERS

       The following modifiers are supported on Intel IcelakeX IRP 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.
