I think something much simpler would be better. I think there's even some patches floating to lift this to the dma-buf level (at least for output ind debugfs), but we'd still need a generic thing at the drm_gem_bo level. If we can subsume at least some of the existing ioctls (with a thin wrapper) to this new thing I'm all for it. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
