       libpfm_intel_icx_unc_ubox - support for Intel IcelakeX Server UBOX       uncore PMU

SYNOPSIS        top

#include <perfmon/pfmlib.h>PMU name: icx_unc_uboxPMU 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:eEnable 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.tSet 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].iInvert the threshold (t) test from strictly greater than to              less or equal to. This is a boolean modifier.
