I should have : remembered why it wouldn't. The next step would be to try a workaround: : Comment out the two calls to drm_initmap() in radeon_cp.c. : : We really need a nice call to grab the start/offset of a pci resource : given the rid. We can avoid it now, but we might not be able to given : where the DRM is headed. rman_get_start() doesn't do the trick? Or do you need to know what it is before the bus_alloc_resource?
