This "residency map" is just the "MinMip texture" that was described in the D3D sampler feedback spec. I want to know how the hardware will update the tile mappings itself. This patent is pretty useless in trying to describe that process ...
I don't think you've really got all that much of a grasp on how on what exactly sampler feedbacks are or how they interact with tiled resources so let me explain. Feedback maps can only be either a committed or a placed resource. A tiled resource is normally created as a reserved resource. The
UpdateTileMappings API specifically needs to be called to change the tile mappings in a reserved resource. Just having a feedback map alone won't automatically do this for you like you seem to keep implying ...
Feedback maps are a totally different type of resource compared to a reserved/tiled resource and are separate from each other ...
