Subject: [Qemu-devel] [PATCH qemu v2 0/4] spapr_pci, vfio: NVIDIA V100 + POWER9 passthrough
Date: Thu, 14 Feb 2019 16:21:40 +1100 [thread overview]
Message-ID: <20190214052144.59541-1-aik@ozlabs.ru> (raw)
This is for passing through NVIDIA V100 GPUs on POWER9 systems.
This implements a subdriver for NVIDIA V100 GPU with coherent memory and
NPU/ATS support available in the POWER9 CPU.
1/4 is a preparation for bigger DMA windows.
2/4 is a small cleanup.
Here is the kernel driver:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/vfio/pci?h=v5.0-rc6&id=7f92891778dff62303c070ac81de7b7d80de331a
SLOF changes already went in.
This depends on "pci: Move NVIDIA vendor id to the rest of ids" (posted separately).
This is based on sha1
1ea6057 Mark Cave-Ayland "mac_newworld: change default NIC to sungem for mac99 machine".
Please comment. Thanks.
Alexey Kardashevskiy (4):
vfio/spapr: Fix indirect levels calculation
vfio/spapr: Rename local systempagesize variable
vfio: Make vfio_get_region_info_cap public
spapr: Support NVIDIA V100 GPU with NVLink2
