[BEGINNER] How to send Ethernet packets from HPS to FPGA on Cyclone V ? (DMA)
Lastly, what I think would be the way - DMA so that the CPU doesn't really have to copy each and every packet into RAM - but I have no idea how to go about this, but I've seen some syscalls that shall be able to tell Linux to actually 'put' packets there (I really am a beginner, sorry guys, I'm trying my best tho!). And I've had a slight experience with u-dma-buf kernel module (https://github.com/ikwzm/udmabuf), which might be the place we wanna Linux to put packets to. Then, we'd give the FPGA the address of the buffer allocated by u-dma-buf and it would simply start the processing from there. Is that correct or am I missing something ?
