This is for passing through NVIDIA V100 GPUs on POWER9 systems.
7/7 and https://github.com/aik/linux/commit/f41f5666d27b31c1
have 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 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:
