Hi All,
I am working on an IOMMU driver feature that allows a user to specify if the
DMA from a device should be translated by IOMMU or not. Presently, we support
only all devices or none mode i.e. if user specifies "iommu=pt" [X86] or
"iommu.passthrough" [ARM64] through kernel command line,
Hi Ricardo,

Hi Joerg,
Is there anything I need to do to get this patch into linux-next? My
patch to convert the amd iommu driver to use the dma-iommu ops depends
