From: Alexey Kardashevskiy <aik@xxxxxxxxx> 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)).
