• 61a88a76b   Documentation/Intel-IOMMU.txt: Modify definition of DRHD ... Browse Code »

  Hi all,

  According to "Intel Virtualization Technology for Directed I/O" specification,
  DRHD stands for "DMA Remapping Hardware Unit Definition" , not "DMA
  Engine Reporting Structure".

• 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.

  MSI interrupt handler registrations and fault handling support for Intel-IOMMU

  This patch enables the MSI interrupts for the DMA remapping units and in the
  interrupt handler read the fault cause and outputs the same on to the console.

• 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.
