NAME top

       libpfm_intel_icx_unc_ubox - support for Intel IcelakeX Server
       UBOX uncore PMU

SYNOPSIS top

       #include <perfmon/pfmlib.h>

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

DESCRIPTION top

       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 top

       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.
