This just adds the structures and interfaces required for adding/deleteing gpu screens at the DDX level. The platform probe can pass a new flag to the driver, so they can call xf86AllocateScreen and pass back the new gpu screen flag. It also calls the gpu screens preinit and screeninit routines at startup. v2: fix delete screen use after free. v3: split out pScrn into separate patch Reviewed-by: Keith Packard <keithp@keithp.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
