Here is the place for your fantasy. At the first glance it seems reasonable to use FPGA driver ioctl's for initializing FPGA and tuning FPGA knobs (signals, registers, whatever) and have another driver for each type of the I/O card, which could be char/block/socket, depending on the nature of the given card. Of course that card driver will use some functions exported by the FPGA driver. -- HTH Vitaly Demyanec _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
