I mean, I get there's not much love for ION in staging, and I too am eager to see it go, but I also feel like in the discussions around submitting the dmabuf heaps at talks, etc, that there was clear value in removing ION after a short time so that folks could transition being able to test both implementations against the same kernel so performance regressions, etc could be worked out. I am actively getting many requests for help for vendors who are looking at dmabuf heaps and are starting the transition process, and I'm trying my best to motivate them to directly work within the community so their needed heap functionality can go upstream. But it's going to be a process, and their first attempts aren't going to magically land upstream. I think being able to really compare their implementations as they iterate and push things upstream will help in order to be able to have upstream solutions that are also properly functional for production usage. The dmabuf heaps have been in an official kernel now for all of three weeks. So yea, we can "delete [ION] and see who even notices", but I worry that may seem a bit like contempt for the folks doing the work on transitioning over, which doesn't help getting them to participate within the community. thanks -john _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
