This is for passing through NVIDIA V100 GPUs on POWER9 systems. 20/20 has the details of hardware setup. 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 (both guest and host kernels): https://github.com/aik/linux/tree/nv2 Matching qemu is pushed to github: https://github.com/aik/qemu/tree/nv2 Skiboot bits are here: https://github.com/aik/skiboot/tree/nv2 The individual patches have changelogs. v7 fixes compile warning and updates a VFIO capability comment in 20/20. Please comment. Thanks.
