• 12c7389ab   iommu-api: Remove iommu_{un}map_range functions ... Browse Code »

  These functions are not longer used and can be removed
  savely. There functionality is now provided by the
  iommu_{un}map functions which are also capable of multiple
  page sizes.

• 676517869   iommu-api: Add ->{un}map callbacks to iommu_ops ... Browse Code »

  This patch adds new callbacks for mapping and unmapping
  pages to the iommu_ops structure. These callbacks are aware
  of page sizes which makes them different to the
  ->{un}map_range callbacks.

• cefc53c7f   iommu-api: Add iommu_map and iommu_unmap functions ... Browse Code »

  These two functions provide support for mapping and
  unmapping physical addresses to io virtual addresses. The
  difference to the iommu_(un)map_range() is that the new
  functions take a gfp_order parameter instead of a size. This
  allows the IOMMU backend implementations to detect easier if
  a given range can be mapped by larger page sizes.
  These new functions should replace the old ones in the long
  term.

• 4abc14a73   iommu-api: Rename ->{un}map function pointers to ->{un}map_range ... Browse Code »

  The new function pointer names match better with the
  top-level functions of the iommu-api which are using them.
  Main intention of this change is to make the ->{un}map
  pointer names free for two new mapping functions.

  Fix zillions of -mm x86_64 allmodconfig build errors - the file uses
  EXPORT_SYMBOL() and kmalloc but misses the needed includes.

• dbb9fd863   iommu: Add domain_has_cap iommu_ops ... Browse Code »

  This iommu_op can tell if domain have a specific capability, like snooping
  control for Intel IOMMU, which can be used by other components of kernel to
  adjust the behaviour.

• fc2100eb4   add frontend implementation for the IOMMU API ... Browse Code »

  This API can be used by KVM for accessing different types of IOMMUs to
  do device passthrough to guests. Beside that this API can also be used
  by device drivers to map non-linear host memory into dma-linear
  addresses to prevent sgather-gather DMA. UIO may be another user for
  this API.
