It's currently in it's 11th version. Michael(or any other person who can merge this patchset) can you please look at the possibility of merging this patches ?Are there more issues with these patches since the last version barely attracted any comments ? Changes since V10 include -Support for huge pages including some obscure AMD IOMMU feature that allows default page size override[Jan]. -Fixed an issue with generation of interrupts. We noted that AMD IOMMU has BusMaster- and is therefore not able to generate interrupts like any other PCI device. We have resulted in writing directly to system address but this could be fixed by some patches which have not been merged yet. Changes since v9 -amd_iommu prefixes have been renamed to a shorter 'amdvi' both in the macros and in the functions/code. The register macros have not been moved to the implementation file since almost the macros there are basically macros and I reckoned renaming them should suffice. -taken care of byte order in the use of 'dma_memory_read'[Michael] -Taken care of invalid DTE entries which is still subject discussion. I will make any necessary changes based on discusion outcome.[Jan] -An issue with the emulate IOMMU defaulting to AMD_IOMMU has be fixed[Marcel] You can test this patches by starting with parameters qemu-system-x86_64 -M q35,iommu=on,x-iommu-type=amd -m 2G -enable-kvm -smp 4 -cpu host -hda file.img -soundhw ac97 emulating whatever devices you want. Not passing any command line parameters to linux should be enough to test this patches since the devices are basically passes-through but to the 'host' (l1 guest). You can still go ahead pass command line parameter 'iommu=pt iommu=1' and try to pass a device to L2 guest. This can also done without passing any iommu related parameters to the kernel.
