Hi,
This series adds support for SMMUv3. Stream IDs have been added to the
cell config and they need to be specified in the config before a cell
can use a stream.
The SMMU driver exposes an emulated SMMU to the guests cells by trapping
access to the MMIO registers. This is not emulation in the sense that we
fully emulate the device top to bottom. The emulation is used to provide an
interface to the SMMU that the hypervisor can control to make sure the
inmates are not doing anything they should not. The actual translations
are done by hardware.
The IOMMU definition has been generalised. The AMD and Intel IOMMU
drivers have been updated to use this definition. I am not very familiar
with these drivers, so please do take a look to make sure the changes
are correct and don't create any unwanted problems.
Limitations and work left are mentioned in the 6th patch.
