[chop cc list] s390 mdev maintainers, Can I ask your help to test this with the two S390 mdev drivers? Now that gvt is passing and we've covered alot of the QA ground it is a good time to run it. Take the branch from here: https://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd.git/log/?h=for-… And build the kernel with CONFIG_VFIO_CONTAINER=n CONFIG_IOMMUFD=y CONFIG_IOMMUFD_VFIO_CONTAINER=y And your existing stuff should work with iommufd providing the iommu support to vfio. There will be a dmesg confirming this. Let me know if there are any problems! If I recall there was some desire from the S390 platform team to start building on iommufd to create some vIOMMU acceleration for S390 guests, this is a necessary first step. Thanks, Jason
