This series includes Libvirt support for a new QEMU feature for the spapr (PPC64) machine, NVIDIA V100 + P9 passthrough. Refer to [1] for the version 3 of this feature (same version used as a reference for this series).
v2 has a entirely different approach from the first patch [2] that simply grants IPC_LOCK to the QEMU process:
- first patch is a cleanup to make it easier to insert additional logic in the code
- patch 2 contains helper functions that browses the device tree at /proc/device-tree to detect if a given VFIO PCI device is using a NVLink2 bus
- patch 3 includes the passthroughLimit calculation for PPC64 guests that are using NVLink2 passthrough GPUs.
Is there something more (like a doc) apart from the patches that I can use to crosscheck your implementation? Erik
