You can check the temperature by running nvidia-settings.
If you can't see the temperature in it, then nvidia
doesn't support it on your card and
I'm not sure we should :s
Thanks for the vbios you sent me in private. For the
others, the reason why he doesn't have temperature
anymore is because his vbios lacks sensor calibration
values.
"Thermal Settings" is:
Thermal Sensor Information:
ID: 0
Target: GPU
Provider: GPU Internal
Temperature: 70 C (now)
I looked in Windows program SpeedFan. It found Nvidia PCI
card and reported "GPU Temp" about 68-70 C. So it looks
like both nvidia driver and windows SpeedFan program
reading same values.
the temperature is like. It won't be perfectly accurate
but there is some kind of default for nvidia cards of this
generation.
report similar values as windows or nvidia driver.
Please test this patch. Be aware that temperature with nouveau
will be higher than with the blob.
I only want to see if nouveau reports a temperature.
The only way to be sure if the values are good-enough would be
to use the blob and run:
nvapeek 0x15b0
Please send me the result along with the temperature reported
by nvidia at the time of the peek.

PS: This patch has only be compile-tested, I don't have access
to an nv4x right now.
now after patch nouveau report temperature:
$ sensors
...
nouveau-pci-0500
Adapter: PCI adapter
temp1: +63.0°C (high = +95.0°C, hyst = +3.0°C)
(crit = +145.0°C, hyst = +2.0°C)
(emerg = +135.0°C, hyst = +5.0°C)
...As you didn't run nvapeek 15b0 when running nouveau it is hard to tell
I found that nvidia binary driver has command line utility
nvidia-smi which report same temperature as X utility nvidia-
settings. So I will use nvidia-smi (if it is OK).
And after reboot nvidia report another temperature value:
$ nvidia-smi -q -d TEMPERATURE
...
GPU 0000:05:00.0
Temperature
Gpu : 70 C
Immediately I called nvapeek command:
$ nvapeek 0x15b0
000015b0: 1000008e
So value reported by nouveau is lower than value reported by
nvidia binary driver.
if it is due to
calibration values or because the temperature was lower.
Could you please read the temperature + peek 15b0 when running nouveau?My idea is that register does not contains temperature. Both nouveau and
Anyway, it is weird because I cannot find 70°C with 0x8e as an input
temperature and with
the current default values :o
nvidia driver when show different temperature it does not show different output
from "nvapeek 0x15b0".
Now I started computer with nouveau driver. Temperature is incresing, but
nvapeek 0x15b0 is still same.
So do you really needs other tests with nvapeek 0x15b0? Is that register
correct?
