Add acpiiort(4), a driver for the ACPI I/O Remapping Table. This table contains information which IOMMUs we have and how the devices are routed. ok kettenis@ |

Add smmu(4), a driver the ARM System MMU. This IOMMU is basically a regular ARM CPU MMU re-used for I/O devices. Implementations can have a mix of stage-2 only and stage-2/stage-2 context blocks (domains). The IOMMU allows different ways of grouping devices into a single domain. This implementation only supports SMMUv2, since there is basically no relevant SMMUv1 hardware. It also only supports AArch64 pagetables, the same as our pmap. Hence lots of code was taken from there. There is no support for 32-bit pagetables, which would have also been needed for SMMUv1 support. I have not yet seen any machines with SMMUv3, which will probably need a new driver. There is some work to be done, but the code works and it's about time it hits the tree. ok kettenis@ |

Have acpipci(4) look for a matching SMMU in the IORT. ok kettenis@ |
