    RE: About the IOMMU implementation
    For example, to be more specific. Is the IOMMU driver started before the hard-disk driver or does it do passthrough for it? Thank you. Regards, Adriana

    About the IOMMU implementation
    Hi, I have a question related to the IOMMU driver implementation in linux kernel. Is the IOMMU driver started before any drivers that might use DMA transfers, as it has to map all DMA buffers in its page tables? Or it can be started at any moment but in this case, the mappings must be stored somewhere? Thank you. Regards, Adriana
