As you didn't run nvapeek 15b0 when running nouveau it is hard to tell if it is due to calibration values or because the temperature was lower. Could you please read the temperature + peek 15b0 when running nouveau? Anyway, it is weird because I cannot find 70°C with 0x8e as an input temperature and with the current default values :o I wait some some and started nvidia-smi and nvapeek again, here are results: $ nvidia-smi -q -d TEMPERATURE ...

Well, it looks like the temperature reading is very noisy! Could you please get the temperature + peek when the card is as hot as possible? There is a very effective solution to get a GPU hot, use a hair drier. If you could get your GPU to at 110°C (or less, if you feel like it is too much), that could help me check the formula and default values. PS: I attached a new version of the patch that should improve the temperature accuracy for nv43s. Could you test it and send me your kernel log?

nouveau: temperature on nv40 is unavailable since ad40d73ef533ab0ad16b4a1ab2f7870c1f8ab954
Hello, after commit ad40d73ef533ab0ad16b4a1ab2f7870c1f8ab954 temperature information from lm sensors is not available on my Nvidia 6600GT graphics card. There is no nouveau hwmon entry in sysfs anymore. Why it was removed? Can I help with debugging? I'd like to see temperature sensor working again. -- Pali Rohár pali.ro...@gmail.com signature.asc Description: This is a digitally signed message part.

Great, I'll cook you a patch in a bit and you'll see what the temperature is like. It won't be perfectly accurate but there is some kind of default for nvidia cards of this generation. -- To unsubscribe from this list: send the line unsubscribe linux-kernel in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
