Nouveau - Dec 2013 - [Bug 71455] Thermal management in nouveau running hot 3.12.0+ kernel

https://bugs.freedesktop.org/show_bug.cgi?id=71455

--- Comment #3 from Bob Gleitsmann <rjgleits at bellsouth.net> ---
The fan PWM setting is derived from priv->cstate. The value it gets from
there
is zero. So the setting of PWM for NV40 is working correctly,
"inverting" the
percent setting to get the value set in 0xb20010f0. Probably priv->cstate is
never initialized. I'll bet that wasn't intentional.
