            Bug ID: 98852
           Summary: Nvidia graphics card fan not running or to slow,
                    danger of overheating
           Product: xorg
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
          Reporter: susebugzilla-BGeptl67XyCzQB+pC5nmwQ@public.gmane.org
        QA Contact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org

I upgraded from Opensuse 42.1 to 42.2.

I have a nvidia geforce GT240 grapics card in my system.
When i start opensuse Leap 42.2, the fan of the graphics card 
stops, it starts running very slowly, after the cooler of the card
has become very hot.

During the installation of opensuse 42.2 the nouveau driver is used.

(When in the dual boot system windows 10 is booted,
or a reboot is done and the system goes into the bios,
the fan spins up immediately.)

The documentation on how to set the fan speed is located here:
https://www.kernel.org/doc/Documentation/thermal/nouveau_thermal

However, it is quite likely that we do not configure the PWM controler
properly. Looking at your vbios, I see that the expected frequency is 42kHz
which is quite high and may be the reason why your fan would not rotate
properly (unless it is set to 100%).

What would be really useful, would be for you to try to force the fan to 100%,
by following the guide I sent you.

I guess you should also try other fan speeds too, report back when you have
tried.
The expected result would be for the fan to barely spin at 10% and gradually
spin up until reaching 100%. At 100%, the noise should be quite loud.

If this is the behaviour you see, then I would like you to set the fan mode to
automatic (mode 2) and monitor the fan speed set by Nouveau by reading pwm1.

If the fan speed does not change with temperature, it would be useful to paste
here kernel logs with nouveau.debug="ptherm=debug" set in your kernel command
line (you can edit this from grub directly, when booting up).

I list here the commands I have given as root.

But the fan did not start.

Have I used wrong values ?

I'am a little bit confused by the description where is written, that
some parameter are in milli-degree, but I can't recognize what of the
parameters this are.

So I played around with values from 1 to 1000 to hit as blind user
a value, where the fan could start.

In the appendix hwmon-handling  is the protocol of my session.

I did some further tests with setting of the boot time parameter
in the yast kernel parameter line.

Also with 

nouveau.runpm=0  or
nouveau.runpm=1  
the fan on the graphic card does not start.

Beside this I use for PC tests also the systemrescue-Distribution
where DVD images can be found on 
http://www.system-rescue-cd.org/Download

I observed that until version 4.6.1 the fan on the graphic card was running.
Starting with version 4.7.1 the fan stops after loading of the rescue system.

This is really weird as there are no changes related to the fan between 4.6 and
4.7 :s

I guess, at this point, we need to check out what nouveau is doing versus what
the blob is doing.

Please download and compile envytools[0] and run the following command when
running Nouveau, then when using the proprietary driver:
 - nvapeek e114 10

Please report back.

I downloaded the envytools Software from your link and tried an installation.
I got following error messages:

 CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build

On the system the whole linux kernel development environment is installed
and all packages mentioned in the envytools description.
What have I to do, that the compilation is possible ?

There is a ninja package on Arch Linux, I would guess that something similar
exists on openSUSE.

Try with `cmake -G"Unix Makefile" .` instead, or clear the CMake cache (delete
CMakeCache.txt and CMakeFiles should be enough I think), and try again to run
`cmake .`.

Exactly what I did not want to see :s

Could you attach here your vbios? You can get it by running: nvagetbios -s prom
> vbios.rom

Please also add the output of: nvapeek 101000

Thanks in advance, you uncovered a deeper bug!

Here the output of the nvapeek command:

nvapeek e114 10
0000e114: 00000001 00000000 00000000 80000000

I added the vbios.com as attachment.

no, you should run: nvapeek 101000 :)

Sorry, the last output was not the wished one.
Now the correct output:

nvapeek 101000
00101000: 80408c8e

Thanks for being super helpful and responsive! We compute the clock tree
correctly so now, the problem is that we do not detect which PWM controller we
need to write to.

So, let's have a look at nouveau's code now and see what could go wrong :)

Nothing obvious comes to mind. Especially not something related to the fan. If
it is a regression between 4.6 and 4.7, is it too much to ask for a bisect? :s

Hello,
what have I to do, to produce a bisect?

Have I to install a special version of a kernel?

I can make an installation on a other harddisk.

I have got a second Geforce GT240 card, which shows the same Fan-symptoms.
Would it help you, if I send the pcie-card to you for tests in your own
test-equipment ?

If you will do own tests, you have not to send the card back to me.
Regards
Egon
