Dear all,
Lets say that my GPU includes a chip called ADT7473. I am interested in receiving information from this chip about the temperature of my card. My question is, how to access this chip? is that accomplished using the IN/OUT instructions?
EDIT:
I might add those lines found in the chip's documentation :
Table 18. Temperature Reading Registers (Power−On Default = 0x01) (Note 1 and 2)
0x25 : Read−only : Remote 1 temperature reading (8 MSB of reading). (Note 3 and 4)
0x26 : Read−only : Local temperature reading (8 MSB of reading).
0x27 : Read−only : Remote 2 temperature reading (8 MSB of reading). (Note 3 and 4)
I was told that there should be an interface chip on the card, which can be accessed. How can I know the port which should be used? or the name of the chip?
