Temperatur der Grafikkarte auslesen

[DevidEspenschied]

But how the I2C bus from the ATI card have to be accessed, what I2C commands need to be used, that is nowhere documented.

Even if you have a ring 0 driver (there are several ones free available though the internet), you need a plan do access the I2C bus.

And for ATI cards there is maybe a DLL to gain the temperatures, and I believe I have debugged such one already. But the problem is, that no one have the exact function calls for the DLL functions, which are necessary to read the temp. nVidia for example does have a free available PDF document with the descriptions of these calls.
