At FOSDEM 2009 in Keith Packard's talk on the rebuilt Linux desktop, he shared the progress made in composited 3D, monitor auto-plugging, 2D/3D/media shared objects, kernel mode-setting, and kernel-based 2D drawing. Allowing these problems to be addressed was the Graphics Execution Manager for kernel memory management. The Graphics Execution Manager was used instead of TTM (which we talked about several times before at Phoronix) and it allows for persistent objects, global name, and pageable contents.
