Looks like Dave is making some progress on drm usage of buffer sharing between gpu's.. if that is ready to go in at the same time, it might be a bit logistically simpler for him to put dmabuf in the same pull req. I don't have strong preference one way or another, so do what is collectively simpler ;-) BR, -R >> >> Dave. > Best regards, > ~Sumit. > -- > To unsubscribe from this list: send the line "unsubscribe linux-media" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
