Hi, i am currently working on adding fan control to support for the acer-wmi driver. So far i can already control the fans using a hwmon interface, but support for switching between manual and automatic mode is missing. Switching from automatic to manual mode seems to be straight-forward: using WMI method 16 to set the fan speed seems to automatically switch to manual control mode. However switching back to automatic mode uses a different mechanism. Since you are the author of the WMID_gaming_set_fan_mode() function i wanted to ask you how the function exactly works. In the end i hope to use this function to switch fans back to automatic mode. By the way i also found a way to automatically detect the number of CPU and GPU fans for each machine, so maybe we can get rid of the quirk entries for that. Thanks, Armin Wolf
