dmesg with nouveau.debug=debug

If I  try  to  see  how  hot  my  new cards  is I get:

nouveau-pci-0500
Adapter: PCI adapter
temp1:         +0.0?C  (high = +95.0?C, hyst =  +3.0?C)
                       (crit = +100.0?C, hyst =  +5.0?C)
                       (emerg = +135.0?C, hyst =  +5.0?C)


This is  using kernel 3.17-rc1 (32-bit), but same  happens  with older  kernels
, both 32 and 64 bit.

--- Comment #3 from Martin Peres <martin.peres at ensi-bourges.fr> ---
Your card is supposed to have an external temperature probe (an ADT7473). For
some reason, it fails to be detected *AGAIN*.

Here is what your vbios says: EXTDEV 0: type 0x70 [ADT7473] at 0x5c defbus 0

You may try to put 100 instead of 40 at this line:
http://cgit.freedesktop.org/~darktama/nouveau/tree/nvkm/subdev/therm/ic.c#n63
If it still does not appear, then I'm sorry, you'll have to check it
works with
the proprietary driver and if so, I would need a mmiotrace :s

Looks good.

It is not supposed to fix the internal temperature sensor, it supposed to
create another temperature sensor. Can I see the kernel logs with this patch
applied ? Make sure your initramfs doesn't contain another version of
nouveau.ko

Hm, log  should  be available as
https://bugs.freedesktop.org/attachment.cgi?id=104991 (at 11.55 you  can see 
"[11.544288] nouveau D[     I2C][0000:05:00.0] using custom udelay 100
instead
of 10" - I assumed  it  worked at this stage. But then - I saw  no another 
nouveau adapter ..what if nouveau just stops  adding sensors  after  finding 
'ghost' internal thermal sensor  ?

Nah, that's not how the code works. Can you test with the proprietary driver
to
see if it exposes a temperature? If it does work, could you make a mmiotrace of
it, please?

Not  worked  with NVIDIA-Linux-x86-325.15.run (no temperature  data in
nvidia-settings,  no temperature  data  in nvidia-smi output).

I also  found  those  threads:
http://en.expreview.com/2008/01/21/review-palit-8800gs-384mb-768mb/214.html/25
http://www.techpowerup.com/forums/threads/palit-geforce-8800gs-384mb-with-no-sensor-and-two-pin-fan.61530/

so, may be  this  is  hardware defect ...

Possibly... I'll add a test and only display the temperature if the test
succeeds. This way, people won't be mislead into thinking their temperature
probe works but is not accurate.

Thank you for reporting the bug though! I'll close it when I have submitted
the
patch.
