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.
