This is version 2 of the series I sent a while ago [1], adding PASID support to the Arm SMMUv3 driver. Changes since v1: * Dropped the patch adding auxiliary domain support. It's an easy way to test PASID, by populating PASID contexts using iommu_map/unmap(), but I don't know if it will ever have real users. Since v1 I changed my testing gear, and am using the zip accelerator [2] instead of a software model. It only uses SVA and testing auxiliary domains would require additional changes that would never go upstream. SVA requires another 20 patches (including I/O page faults) that I will send later, but at least I know that this will get used. * ioasid patch has been carried by Jacob and should be merged for v5.5 [3] * Split patch "Add support for Substream IDs" into patches 4 and 5. * Added IORT support (patch 3) and addressed other comments.
