But we are not accepting any new ion allocators or changes at the moment, so I don't see how the ion code in the kernel is helping/hurting anything here. There has been a bunch of changes to the ion code recently, in the Android kernel trees, in order to get a lot of the different manufacturer "forks" of ion back together into one place. But again, those patches are not going to be sent upstream for merging so how is ion affecting the dmabuf code at all here? > The dmabuf heaps have been in an official kernel now for all of three > weeks.

But they aren't participating in the community today as no one is touching the ion code. So I fail to see how keeping a dead-end-version of ion in the kernel tree really affects anyone these days. thanks, greg k-h _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
