--- Comment #24 from Chernovsky Oleg adonai@xaker.ru --- Created attachment 105853 --> https://bugs.freedesktop.org/attachment.cgi?id=105853&action=edit 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

READ: cat /sys/class/drm/card0/device/power_fan_control correct values are 0 to 100 on first reads it'll probably show some incorrect percentage value due to manual control not yet enabled

WRITE: echo 40 > /sys/class/drm/card0/device/power_fan_control correct values are 0 to 100
