Wouldn't work as-is, but when ttm bo are a subclass of gem bos should be possible to create something usable based on it. Related question: why there is no drm_gem_object_funcs.mmap() callback? I think it would make sense to have a callback where the bo-specific setup can be done, i.e. what ttm_bo_mmap() or drm_gem_shmem_mmap() are doing, and have some generic function which basically does the lookup, then dispatches. cheers, Gerd _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
