Bug 84721

the above info is extracted from porteus linux that uses binary driver. because I can't stay in the gentoo os with faulted kernel.

Please attach a kernel log from the nouveau driver in the bad state.

Please attach your vbios.

Oh, and also:

sensors (when booted with nouveau)
dmesg (when booted with nouveau, adding nouveau.debug=debug to the kernel command line, and letting it run for at least a minute or two... looking for "FAN target request:" messages)

The same problem with FatDog 7.00b1 64bit.

Hello, I am willing to fix this problem. Please send us your vbios, as Ilia asked. I cannot do anything without it :s

vbois of gt630 by the "using /sys:" method

as requested.
if it is not the correct dump tell me and I will fix it.
but please tell me how to do it if possible.

Sorry for the dely but I wasn't sure if I had to stay that long in that env. but I did it because I need nouveau for hardened kernels

As far as I've checked, the problem appeared in 3.15 kernel. I've tried hardened-sources-3.14.29 and there's no problem with the fan, at least in auto mode. But since you change the mode to manual (echo 1 > pwm1_enable), the fan gets mad as in 3.15 kernel branch. Related info from me: https://forums.gentoo.org/viewtopic-t-1009318.html

I didn't do anything to the kernel and I did change nothing in settings.
the tests I have done are all in the live usb env and all from the 3.16 and above kernels.
 voild-linux-x86_64-01-2015-enlightenment.iso
 fatdog-x86_64-7.00b1.iso
 latest lileblue.iso
 ... and so on
IT MAY BE statred at 3.15 but all of live cd/usb (s) that I used were 3.16 or above I assumed it started by then.

@r004, I had the same problem with my system and I've made little investigation. Indeed the problem appeared in 3.15 and it's still there in latest 3.18 kernel. For the quick and easy work-around use kernel 3.14 or lower.

Identifying the commit that broke things between 3.14 and 3.15 would go a long way to solving this issue.

git bisect start v3.15 v3.14 -- drivers/gpu/drm/nouveau

should limit the bisect to just nouveau.

After 7 tries... here's the culprit:

    drm/nouveau/therm: let the vbios decide on the automatic fan management mode
   
    This should fix automatic fan management on fermi cards who do not have
    0x46 entries in the thermal table.
   
    On my nve6, the blob sets the default linear range from 40°C to 100°C
    but my nvcf's default values are 40°C to 85°C. Let's keep 85 as a default
    for everyone.

Following to this there was a conversation on #nouveau:

Reverting a part of the above noted patch:

-	/* starting from fermi, fan management is always linear */
-	if (nv_device(bios)->card_type >= NV_C0 &&
-		fan->fan_mode == NVBIOS_THERM_FAN_OTHER) {
-		fan->fan_mode = NVBIOS_THERM_FAN_LINEAR;
-	}

hides the bug away again.

VBIOS of GT 730

I've added my gfx card vbios for further investigation.

(In reply to r004 from comment #1)

You card seems to be similar if not identical to mine, so you might be interested in the discussions and Martin's proposals further down in Bug 80901.

Still happening as 4.11 kernel. I have to use the closed driver or the fan noise will fry my nerves.

Hi there,

im using kernel 4.18 (Ubuntu), and nouveau 1.0.15

fan speed is high here too

Here is my VBIOS

well, i cant attach it!

i get this error message: "The content type is invalid. Valid types must be of the form foo/bar where foo is one of application, audio, image, message, model, multipart, text, video and bar must not contain any special characters (such as "=", "?", ...)."
