Hi,
I am trying to hook up a PCIe host controller that sits behind an IOMMU,
but having some problems.
I'm using the pcie-rcar PCIe host controller and it works fine without
the IOMMU, and I can attach the IOMMU to the controller such that any calls
to dma_alloc_coherent made by the controller dr
18 matches
