Subject: [PATCH kernel 0/3] vfio/spapr_tce: Reworks for NVIDIA V100 + P9 passthrough (part 3)
Date: Mon, 15 Oct 2018 20:42:30 +1100 [thread overview]
Message-ID: <20181015094233.1324-1-aik@ozlabs.ru> (raw)
This is a third set of patches required for passing through NVIDIA V100
with coherent memory. The full patchset is here:
https://github.com/aik/linux/tree/nv2
The matching QEMU is here:
https://github.com/aik/qemu/tree/nv2
This implements a subdriver for NVIDIA V100 GPU with coherent memory and
NPU/ATS support available in the POWER9 CPU.
This does not address the interconnected GPUs, this will be posted as
a separate patchset in a few days.
This depends on:
[PATCH kernel 0/4] vfio/spapr_tce: Reworks for NVIDIA V100 + P9 passthrough (part 1)
[PATCH kernel 0/5] powerpc/powernv/npu: Reworks for NVIDIA V100 + P9 passthrough (part 2)
[PATCH kernel RFC 3/3] powerpc/pseries/iommu: Use memory@ nodes in max RAM address calculation
Please comment. Thanks.
Alexey Kardashevskiy (3):
vfio_pci: Allow mapping extra regions
vfio_pci: Allow regions to add own capabilities
vfio_pci: Add NVIDIA GV100GL [Tesla V100 SXM2] [10de:1db1] subdriver
