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.
