  • 0c02a20ff   intel-iommu: Kill DMAR_BROKEN_GFX_WA option. ... Browse Code »

    Just make it depend on BROKEN for now, in case people scream really loud
    about it (and because we might want to keep some of this logic for an
    upcoming BIOS workaround, so I don't just want to rip it out entirely
    just yet). But for graphics devices, it really ought to be unnecessary.

    When we fix all the opensource gfx drivers to use the DMA api's, at that time
    we can yank this config options out.

  • ba3959276   Intel IOMMU: Intel IOMMU driver ... Browse Code »

    Actual intel IOMMU driver. Hardware spec can be found at:
    http://www.intel.com/technology/virtualization

    This driver sets X86_64 'dma_ops', so hook into standard DMA APIs. In this
    way, PCI driver will get virtual DMA address. This change is transparent to
    PCI drivers.
