[PATCH 0/6] KVM: PPC: IOMMU in-kernel handling

[Alexey Kardashevskiy <aik@ozlabs.ru>]

This series is supposed to accelerate IOMMU operations in real and virtual
mode in the host kernel for the KVM guest.

The first user is VFIO however this series does not contain any VFIO related
code as the connection between VFIO and the new handlers is to be made in QEMU
via ioctl to the KVM fd.

Although the series compiles, it does not make sense without VFIO patches which
are posted separately.

The "iommu: Add a function to find an iommu group by id" patch has already
gone to linux-next (from iommu tree) but it is not in upstream yet so
I am including it here for the reference.


Alexey Kardashevskiy (6):
  KVM: PPC: Make lookup_linux_pte public
  KVM: PPC: Add support for multiple-TCE hcalls
  powerpc: Prepare to support kernel handling of IOMMU map/unmap
  iommu: Add a function to find an iommu group by id
  KVM: PPC: Add support for IOMMU in-kernel handling
  KVM: PPC: Add hugepage support for IOMMU in-kernel handling
