Subject: [Qemu-devel] [PATCH qemu v4 0/3] spapr_pci, vfio: NVIDIA V100 + POWER9 passthrough
Date: Thu, 7 Mar 2019 16:05:15 +1100 [thread overview]
Message-ID: <20190307050518.64968-1-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.
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
This is based on David's ppc-for-4.0 sha1
28aa643760dd Suraj Jitindar Singh "target/ppc/spapr: Clear partition table entry when allocating hash table".
Please comment. Thanks.
