After you've got through the examples in Linux Device Drivers v3, you can take a look at drivers/video/xilinxfb.c for an example of a driver that works with an FPGA ip core. Unfortunately there isn't a simple xilinx GPIO driver in the mainline kernel at the moment, otherwise I'd point you there. Cheers, g. -- Grant Likely, B.Sc., P.Eng.
