Nouveau Driver Gets Fan Control Modes

[MuPuF]

One option is badly named. "none" implies off, it would be better as "bios", or "default".

Please fix before it's in kernel and can't be changed

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).

Well, if they can handle manual fan control + thermal sensors, I don't see why an automatic fan management mode couldn't be slapped together based on temperature thresholds (either system or user-defined).

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.

It just hit me that running Nouveau will probably wear you fan out compared to the proprietary driver, all in an attempt to avoid over heating They better get that fan controll working automatic soon

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.

This sounds great! How do the nouveau drivers compare with the proprietary drivers? I wanna try them out on my HP touchsmart.

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.

Hooray for fan management! I don't even know what kind of fan I have, but any tangible advances in Nouveau's power/thermal management actually landing in the kernel is very welcome.
