[Qemu-devel] [PATCH v2 0/9] spapr_pci: Prepare for VFIO

[Alexey Kardashevskiy]

This patchset prepares QEMU for VFIO support on SPAPR. It also does
preparations for Dynamic DMA window feature which allows to
create DMA windows with 16MB IOMMU pages which will allow to map
the entire guest RAM for DMA at almost no cost.

Changelogs are in the patches.

  spapr_iommu: Enable multiple TCE requests
  spapr_pci: Introduce a finish_realize() callback
