This is a second 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 patchset reworks NPU DMA code to be used with VFIO. The exported symbols are called from the NVIDIA driver so they must be able to work in both powernv and pseries platforms. This depends on skiboot's "npu2: Clear XTS_BDF_MAP when destroying context for next init_context" posted earlier today. Please comment. Thanks. Alexey Kardashevskiy (5): powerpc/powernv/npu: Add helper to access struct npu for NPU device powerpc/powernv/npu: Collect all static symbols under one struct powerpc/powernv: Detach npu struct from pnv_phb powerpc/powernv/npu: Factor out OPAL calls from context manipulation powerpc/powernv/npu: Add helper to map GPU to LPAR arch/powerpc/include/asm/pci.h | 4 + arch/powerpc/platforms/powernv/pci.h | 18 +- arch/powerpc/platforms/powernv/npu-dma.c | 298 ++++++++++++++++++++---------- arch/powerpc/platforms/powernv/pci-ioda.c | 9 +- 4 files changed, 212 insertions(+), 117 deletions(-) -- 2.11.0
