[PATCH v6 0/7] Add virtio-iommu driver
...f dependencies on ACPI and DT and OF and the rest of the zoo.
But the portable solutions are ACPI and DT.
Describing the DMA dependency through a device would require the guest
to probe the device before all others. How do we communicate this?
* pass a kernel parameter saying something like "probe_first=00:01.0"
* make sure that the PCI root complex is probed before any other
platform device (since the IOMMU can manage DMA of platform devices).
* change DT, ACPI and PCI core code to handle this probe_first kernel
parameter.
Better go with something standard, that any OS and hypervisor knows...
