Hi, Stefano! I have seen your negotiation of disabling xen-swiotlb for devices which are controlled by IOMMU in Dom0: https://patchwork.kernel.org/project/xen-devel/patch/alpine.DEB.2.21.2102161333090.3234@sstabellini-ThinkPad-T480s/
As I was thinking to create a common implementation because I have the issue when device controlled by IOMMU using xen-swiotlb fops and bounce buffer as the result. https://lore.kernel.org/xen-devel/060b5741-922c-115c-7e8c-97d8aa5f4...@xen.org/T/ Do you have any future plans to finish implementation for upstream? Cheers!
