Created attachment 105853 [details] [review] experimental patch for CI (BONAIRE etc.) for enabling fan control

So I've come up with patch that enables manual fan override for CI family at least. I've tested it on my BONAIRE card, Radeon R7 260X.

INSTALLATION: After compile and reboot there will be new debugfs file, /sys/class/drm/card0/device/power_fan_control

Hey,

I am the Nouveau developer who added fan management support. I would really advice you follow the hwmon recommendations and name this file pwm1.
