This implements a subdriver for NVIDIA V100 GPU with coherent memory and NPU/ATS support available in the POWER9 CPU. Here is the kernel driver: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/vfio/pci?h=v5.0-rc6&id=7f92891778dff62303c070ac81de7b7d80de331a This is based on David's ppc-for-4.0 sha1 28aa643760dd Suraj Jitindar Singh "target/ppc/spapr: Clear partition table entry when allocating hash table".
