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".
