hack for recognizing sensor on nv43
Hello, this is me again with my useful nv43.
As far as I can see nvidia binary driver can use integrated sensor on my card, while nouveau can't. After some digging I found problem - nouveau can't find some calibration coefficients in vbios. May be they missed completely, or bios slightly misparsed. I'll attach again my vbios, and patch I made after looking at nvclock sources . Patch allow sensor to work, and reported temperature roughly correspond to what I saw with binary driver (looking at raw output I see nouveau still hotter than nvidia, but I can ignore this for now).
Not sure if such hack (?) should go into nouveau, or I (someone) better to find if values really missed from vbios first.
Command for getting raw sensor value:
