Kernel_log

Since Kernel 3.13.x the fan speed of my NVIDIA GeForce GTS240 is much too high.

Output from sensors:
...
nouveau-pci-0100
Adapter: PCI adapter
fan1:        6693 RPM
temp1:        +69.0°C  (high = +95.0°C, hyst =  +3.0°C)
                       (crit = +105.0°C, hyst =  +5.0°C)
                       (emerg = +135.0°C, hyst =  +5.0°C)
...

With any kernel version below, i.e. Kernel 3.12.9 everything is fine. Fan speed around 5000 RPM. 

First I thought it could be related to https://bugzilla.kernel.org/show_bug.cgi?id=71711 but Guenter Roeck recommended to open a bug report against Nouveau:

" ... Looks like Nouveau fan control does not work. No idea what may be causing this ...
well, possibly. There are two suspicious commits between 3.12 and 3.13.
Maybe the "remove everything" commit has undesirable side effects.

eec9901 drm/nouveau/hwmon: fix compilation without CONFIG_HWMON
b9ed919 drm/nouveau/drm/pm: remove everything except the hwmon interfaces to THERM
..."

Thank you,
Roman

Hi Roman,

Thanks for your report. The commits you reference are, I think, un-related. 5k or 6.6k RPM is just insane! As everything looks fine from the kernel logs perspective, could you provide me with your vbios[1]?

I am taking this issue very seriously, so please help me out so as we can fix it!

Cheers,
Martin

vbios.rom

Vbtracetool didn't find file "pci/pci.h" during make. So I did create it with the nouveau module, hope this is OK instead.

Temp is quite high with 84°, isn't it? With Kernel versions < 3.13.x fan speed doesn't get up to 6Ks. I'm using Gnome 3 with Liber8, Firefox, ... nothing spectacular.

This is with Kernel 3.12.9:
---
nouveau-pci-0100
Adapter: PCI adapter
fan1:        4702 RPM
temp1:        +84.0°C  (high = +95.0°C, hyst =  +3.0°C)
                       (crit = +105.0°C, hyst =  +5.0°C)
                       (emerg = +135.0°C, hyst =  +5.0°C)

Looks good, thanks!

Well, 84°C is nothing to be afraid of, especially on old cards. However, looking at your vbios informed me that when your card is at 60°C, the fan speed should be 35% and 100% at 90°C.

Could you try to check if manual fan management works perfectly (try 0 -> 100% in 10 steps) both on the 3.12.9 and 3.13.x?

If this works fine, then I would like you to load nouveau with the following parameter and send me the kernel log:
debug="PTHERM=debug"

How can I set the fan management to manual mode? 
With pwmconfig I can only test the fans on the motherboard apparently.

Silly me, I forgot to add the link!

Obsolete, changed my hardware
