   in the fast path enqueue burst operation.
 
 
-**Polling memory location** (default ``ddr``)
-
-  ML cnxk driver provides the option to select the memory location to be used
-  for polling to check the inference request completion.
-  Driver supports using either the DDR address space (``ddr``)
-  or ML registers (``register``) as polling locations.
-  The parameter ``poll_mem`` is used to specify the poll location.
-
-  For example::
-
-     -a 0000:00:10.0,poll_mem="register"
-
-  With the above configuration, ML cnxk driver is configured to use ML registers
-  for polling in fastpath requests.
