Thx, my driver looks mostly same. But i need some more functionality like blinking, and if i understand the most documentation right this could be done by the led framework, too. i haven't already figured out how to split the functionality beetween kernel and userspace in the best way. > I think it would be good to make it depend on some PCI device, but > not sure if there's anything unique or specific to the net6501 that I > could use? As i understand right, works the pcistuff a bit different and ioport/solered devices are often implemented as platform driver? for me it makes sense, because you need no hotplugcapability and the device never change (ok, only until we figure out how to play around with the xilinx ;) ) > Also, still don't know if I can probe the hardware? i remap some memory and take a look if there is a combios or not. i think thats still the best way to probe. But i have no source here in the train.
