[Qemu-ppc] [PATCH qemu RFC 0/7] spapr_pci, vfio: NVIDIA V100 + P9 passthrough

[Alexey Kardashevskiy]

This is for passing through NVIDIA V100 GPUs on POWER9 systems.
22/22 has the details of hardware setup.

This implements a subdriver for NVIDIA V100 GPU with coherent memory and
NPU/ATS support available in the POWER9 CPU. This also implements
required platform support for both powernv (host) and pseries (guest)
platforms.

This is pushed on github:
https://github.com/aik/linux/tree/nv2-stage4

QEMU bits are here (will post separately):
https://github.com/aik/qemu/tree/nv2-stage4

Skiboot bits are here (will post separately as well):
https://github.com/aik/skiboot/tree/nv2-stage4


Please comment. Thanks.



Alexey Kardashevskiy (7):
  vfio/spapr: Fix indirect levels calculation
