I think it should be set only on platforms that actually require 64K pages. So IIUC simply IS_BATTLEMAGE() or if it's known that future DGFX has this restriction too IS_BATTLEMAGE() || (DISPLAY_VER() >= 20 && IS_DGFX()) ? Then the BMG and LNL checks in plane_has_modifier() wouldn't be needed either. --Imre

It's bit of a trick to check with display versions we're on Xe2 which to me is synonym to gfx ver >= 20 but I'll make v2 with this change. It is expected future dgfx will have same 64K requirement. /Juha-Pekka
