This implements support for NVIDIA V100 GPU with coherent memory and NPU/ATS support available in the POWER9 CPU. The aim is to support unmodified vendor driver in the guest. This is pushed to github: https://github.com/aik/qemu/tree/nv2-stage4 The host and guest kernel tree is pushed on github as well: https://github.com/aik/linux/tree/nv2-stage4 Skiboot bits are here: https://github.com/aik/skiboot/tree/nv2-stage4 Please comment.
