[PATCH QEMU 00/12] vfio: pci: Enable DDW and in-kernel acceleration

[Alexey Kardashevskiy]

This makes use of kernel patchsets:
[PATCH v1 00/16] powernv: vfio: Add Dynamic DMA windows (DDW)
[PATCH v1 0/7] powerpc/iommu: kvm: Enable MultiTCE support
[PATCH v1 00/13] powerpc: kvm: Enable in-kernel acceleration for VFIO

I am posting it for reference here, reviews are still welcome but not required :)


Alexey Kardashevskiy (12):
  spapr_iommu: Disable in-kernel IOMMU tables for >4GB windows
  spapr_pci: Make find_phb()/find_dev() public
  spapr_iommu: Make spapr_tce_find_by_liobn() public
  linux headers update for DDW
  spapr_rtas: Add Dynamic DMA windows (DDW) RTAS calls support
  spapr: Add "ddw" machine option
  spapr_pci: Enable DDW
  spapr_pci_vfio: Enable DDW
  vfio: Enable DDW ioctls to VFIO IOMMU driver
  headers: update for KVM_CAP_SPAPR_TCE_64 and VFIO KVM device
  target-ppc: kvm: make use of KVM_CREATE_SPAPR_TCE_64
  vfio: Enable in-kernel acceleration via VFIO KVM device
