From: Alexey Kardashevskiy <aik at ozlabs.ru>
The first 2 patches in this set add a multi-tce support feature
(adding/deleting several TCE records at once) in real and virtual mode.
The last 2 patches enable real mode acceleration for VFIO and
extend the multi-tce feature to be available for VFIO devices.
The QEMU change is required in order to support this functionality
(additional ioctl to add a new LIOBN and hook it with a specific IOMMU)).
Alexey Kardashevskiy (4):
powerpc: lookup_linux_pte has been made public
powerpc kvm: added multiple TCEs requests support
powerpc: preparing to support real mode optimization
vfio powerpc: added real mode support
