Does anyone know if it is possible to DMA directly into GPU memory from another PCI card? I guess that to be able to do this we’d need to allocate a block of GPU device memory and then get a handle/address for it which could be passed to the DMA master. Is this possible via the CUDA API or some other means? I assume that the GPU acts as a DMA master for the pinned memory transfer ops (?) but can it be pushed into? Has anyone tried this before?
