How to read the GPU temperature

    I'm interested in how you read the gpu temperature in your software? Do you directly access the LM63 chip via the I2C bus or does the ATI-driver export the temperature?

    There is a project called lm_sensors which does hardware monitoring for various sensor chips. They write the following about LM63:

    It would be cool if you could share some knowledge :)

    Thanks, but I know that I have such a chip on my ATI card. Perhaps I didn't write clearly what I wanted to know.

    Let's say I wana write an application that shall display the temperature of the GPU. Where can I read the value from? Does the catalyst driver provide it or do yo access the sensor through the I2C bus?
