      iommu/amd: Split amd_iommu_init function · 8704a1ba
      Joerg Roedel authored
      The hardware-initializtion part of the AMD IOMMU driver is
      split out into a seperate function. This function can now be
      called either from amd_iommu_init() itself or any other
      place if the hardware needs to be ready earlier. This will
      be used to implement interrupt remapping for AMD.

      x86, iommu: Make all IOMMU's detection routines return a value. · 480125ba
      Konrad Rzeszutek Wilk authored
      We return 1 if the IOMMU has been detected. Zero or an error number
      if we failed to find it. This is in preperation of using the IOMMU_INIT
      so that we can detect whether an IOMMU is present. I have not
      tested this for regression on Calgary, nor on AMD Vi chipsets as
      I don't have that hardware.

      x86: Use x86_platform for iommu_shutdown · 338bac52
      FUJITA Tomonori authored
      This patch cleans up pci_iommu_shutdown() a bit to use
      x86_platform (similar to how IA64 initializes an IOMMU driver).
      This adds iommu_shutdown() to x86_platform to avoid calling
      every IOMMUs' shutdown functions in pci_iommu_shutdown() in
      order. The IOMMU shutdown functions are platform specific (we
      don't have multiple different IOMMU hardware) so the current way
      is pointless.
      An IOMMU driver sets x86_platform.iommu_shutdown to the shutdown
      function if necessary.

      x86/amd-iommu: Workaround for erratum 63 · c5cca146
      Joerg Roedel authored
      There is an erratum for IOMMU hardware which documents
      undefined behavior when forwarding SMI requests from
      peripherals and the DTE of that peripheral has a sysmgt
      value of 01b. This problem caused weird IO_PAGE_FAULTS in my
      This patch implements the suggested workaround for that
      erratum into the AMD IOMMU driver.  The erratum is
      documented with number 63.

      x86: consolidate header guards · 77ef50a5
      Vegard Nossum authored
      This patch is the result of an automatic script that consolidates the
      format of all the headers in include/asm-x86/.
      The format:
      1. No leading underscore. Names with leading underscores are reserved.
      2. Pathname components are separated by two underscores. So we can
         distinguish between mm_types.h and mm/types.h.
      3. Everything except letters and numbers are turned into single
