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-97d8aa5f46f4@xxxxxxx/T/
Do you have any future plans to finish implementation for upstream?
Cheers!
