The kernel shouldn't be in the business of telling user space which driver to load. The kernel defers mapping PCI IDs to module names to user space and we should do the same for DRI drivers. And in fact, that's how it does work today. Nothing uses the dri_library_name attribute, and the attribute is in fact broken. For intel devices, it falls back to the default behaviour of returning the kernel module name as the DRI driver name, which doesn't work for i965 devices. Nobody has ever hit this problem or filed a bug about this. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Dave Airlie <airlied@linux.ie>
