    Phoronix: Nouveau Driver Gets Fan Control Modes

    There's some fan/thermal-related commits hitting the Nouveau driver's DRM repository...

    Hey, I understand your complain but not matter what name I find, they are all confusing in some way. In the case of "bios" or "default", it doesn't express that you leave it in this state.
    With FAN_CTRL_NONE, it really means that there is no control and thus, the fan is left untouched. For now, this mode is the default, but starting from next kernel, I will push for auto fan management as a default.

    Anyway, it shouldn't matter as this name is internal only. The user has to use the sysfs interface which uses numbers (as specified in the hwmon interface http://www.mjmwired.net/kernel/Docum...-interface#250).

    Right. The only reason the code has not been pushed is .... that I didn't have the time to fix my patch following the nouveau maintainer's comments before going on vacation. The code is available but won't be merged in Nouveau until I get back home which should be in a few days.
    Hopefully, the thermal work will be almost done for most cards when I'm done merging the patches.

    However, please test the code extensively. We never know what strange clock tree nvidia could have introduced on some chispets!

    Would be grate if the fan control could learn about the system thermal an usage characteristics of to keep an on avarge low noise instead of constantly jumping between idle and max fan speed.

    nvidia auto thermal is terrible.

    constantly have to put the coolbits on and pump up the fan to 50 or 60%. then on idle it's 60 C or so

    if i leave it on the nvidia AUTO mode default is 40%, it idles at 70 C or so, and the fan moves up to 50% at 85 C lol. toastiee

    it was hotter @ idle until i put some sa5 on there.

    My 8800GT fan is very quiet with Nouveau (more quiet than on Windows) and temperature seems fine.
    It seems my GPU is controlling fan by itself.

    Depends on your hardware. From my experience with my NVA5 (NV50/NVA3 generation), it works very well but has slower 3D performance and eats more power than the proprietary driver.
