I have tried to do something I thought really simple this weekend: having a C program on a SoC running Linux with a FPGA component e.g. to pass two integers to the FPGA from HPS with mmap, multiply them, get the result within one clock cycle and without doing much (integrating ) on the bus/bridge. It seems I will have to integrate some bus in qsys and complexify the design beyond what I wanted to validate. While its knowledge is impressive, it continues to spout nonsense fairly easily.
