Hi. I'm implementing my machine control on a ALIX.1b board from pcengines.ch[0]. This board uses an AMD Geode LX and provides both a standard parallel port and GPIO pins (exported from the Winbond W83627hf Super I/O Controller). The driver for this chip in drivers/hwmon/w83627hf.c provides access to these GPIO pins.
Any chance one could turn this into a driver which EMC² can support? The 256MB version of that board is currently available at around 100EUR, so this is a relatively cheap all-in-one PC (only needing a really small, passively cooled case and an external 12V supply, using only about 5 Watts), and with GPIO supported, parallel port+GPIO could drive even the more complex machines. The board exports a total of 21 GPIO pins (GPIO1 bit 0-7, GPIO2 bit 0-6, GPIO3 bit 0-5) from the Winbond chip. So this basically means a second (though more flexible) parallel port on board. Any idea how difficult it would be to make this happen? I have absolutely no (oh well, ok, about 2 hours hacking on some easy watchdog driver which had some reversed logic in it) experience hacking the kernel, let alone hacking on RTAI suitable drivers. Or is it already possible? if so: How?
