This is a third set of patches required for passing through NVIDIA V100 with coherent memory. The full patchset is here: https://github.com/aik/linux/tree/nv2 The matching QEMU is here: https://github.com/aik/qemu/tree/nv2 This implements a subdriver for NVIDIA V100 GPU with coherent memory and NPU/ATS support available in the POWER9 CPU. This does not address the interconnected GPUs, this will be posted as a separate patchset in a few days. This depends on: [PATCH kernel 0/4] vfio/spapr_tce: Reworks for NVIDIA V100 + P9 passthrough (part 1) [PATCH kernel 0/5] powerpc/powernv/npu: Reworks for NVIDIA V100 + P9 passthrough (part 2) [PATCH kernel RFC 3/3] powerpc/pseries/iommu: Use memory@ nodes in max RAM address calculation Please comment. Thanks.
