NAME

       libpfm_intel_icx_unc_ubox - support for Intel IcelakeX Server UBOX uncore PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: icx_unc_ubox
       PMU desc: Intel IcelakeX UBOX uncore PMU

DESCRIPTION

       The  library  supports the Intel IcelakeX UBOX (System configuration controller) uncore PMU. There is one
       UBOX per processor.  Each UBOX PMU implements 4 generic counters.

MODIFIERS

       The following modifiers are supported on Intel IcelakeX UBOX 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  UBOX
              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.
