NAME

       libpfm_intel_icx_unc_iio - support for Intel IcelakeX Server IIO uncore PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: icx_unc_iio[0-5]
       PMU desc: Intel IcelakeX IIO uncore PMU

DESCRIPTION

       The  library  supports  the  Intel IcelakeX IIO (I/O controller) uncore PMU.  Each IIO PMU
       implements 4 generic counters and free running counters (not yet  supported  by  libpfm4).
       The  current  version  of  libpfm4  does not expose the fc_mask and ch_mask filter because
       these are hardcoded in the events provided by the library.

MODIFIERS

       The following modifiers are supported on Intel IcelakeX IIO 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 IIO 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.
