That's the _fini function and the memory type choice I guess. I figure i915 will need exactly the same. /Thomas

I'm not sure how many GPU specific features one needs for "system memory placement but allowing fencing". As to sharing just the fini, I'd be happy to share any code we can but it'd be probably be only between vmwgfx and i915 because the default sys_man doesn't need the evict_all and it's allocated as part of its parent struct so it doesn't need to free. We could trivially add void ttm_fencable_sys_man_fini(struct ttm_device *dev, u32 mem_type) but I'd probably wait until i915 is ready to use it to avoid adding shared code that's only used by a single driver :) z
