...the assumption that the screen represents some gpu context and thus the object space that is addressable. Also what I gathered from the libdrm code. - Copying the fd hash table from the radeon_drm_winsys_create() into nouveau_drm_screen_create(). That fails to work because vl_screen_create() and dri2CreateScreen() both create seperate drm fds resulting in different entries in the hash table (that's not the same - see next point) - static screen singleton (ignoring subsequent drm fds) however nouveau_drm_screen_create is duplicated in both /usr/lib/vdpau/libvdpau_nouveau.so and /usr/lib/xorg/modules/dr...
