I am trying to increase size of direct mw over bar2/3 (64 bit). (to 32M).
I see that switchtec_ntb_mw_direct_get_range(), limits the size to offset or max_mw_size.
If i have 32 LUTs this size is limited to 2MB (64K * 32), I dont understand why is direct mw size dependent on #LUTs ? (I understand #LUTs, will change the base offset of the direct mw).
If I make LUT=0 (in config file, to use direct m wonly configs), the vnic ntb ping fails.
I also see that, with LUT=0, there is no link up event generated for one of the b2b hosts(which loads & configures) the ntb_hw driver later).
