It is getting there and I still do not see why "swiotlb=force" should not work if chosed in the cmdline.Ok, makes sense. But that means we also have the issue in a few other places..Hmm, where? I got broadcom ethernet working with this.
In all the other IOMMU drivers that conditionally forward to the dma direct ops. So it shouldn't affect powerpc.
