[LinuxBIOS] [PATCH] Re: m57sli-s4 and i2c

[Ward Vandewege]

Hi all,

So, here's a patch to enable fan control on the it8716f superio, as used in
the gigabyte m57sli-s4 board. Patch attached.

This allows fan control by loading the it87 module (or compiling it87 support
in your kernel), for instance via the /sys/ interface:

cat /sys/bus/i2c/devices/9191-0290/pwm1
  128 -> fan running at half speed
  echo 255 > /sys/bus/i2c/devices/9191-0290/pwm1
  -> fan goes to full speed

Be careful; there are no safeguards against turning the fans *off*...

This works great for me, but I'm not 100% sure about the pnp_dev_info
structure values, see my other e-mail.

Thanks,
Ward.
