[PATCH v5 5/6] PCI: Add DMA alias quirk for mic_x200_dma

MIC x200 NTB forwards PCIe traffic using multiple alien RID. They have to be added as aliases to the DMA device in order to allow buffer access when IOMMU is enabled. Signed-off-by: Jacek Lawrynowicz Acked-by: David Woodhouse --- Updated quirk comment with requirement that aliases have to be ma

[PATCH v5 3/6] PCI: Add support for multiple DMA aliases

This patch solves IOMMU support issues with PCIe non-transparent bridges that use Requester ID look-up tables (RID-LUT), e.g. PEX8733. The NTB connects devices in two independent PCI domains. Devices separated by the NTB are not able to discover each other. A PCI packet being forwared from one dom
