Hey,
here are two patches for the s390 PCI and IOMMU code. It is
based on the assumption that every pci_dev that points to
the same zpci_dev shares a single dma-table (and thus a
single address space).
If this assupmtion is true (as it looks to me from reading
the code) then the iommu-group setup code in the s390 iommu
driver needs to be updated.
These patches do this and also add support for the
iommu_device_register interface to the s390 iommu driver.
Any comments and testing appreciated.
Thanks,
Joerg
