Re: [ddccontrol-devel] Nvidia proprietary driver support for I2C /bus interface?

[William H. <wi...@ai...>]

Hi Nicolas

Thanks for testing this. I should have followed up and told you that 
I also eventually tried this and it works OK. So that is good news.

I can ask my contacts in ATI engineering about supporting the 
"/dev/i2c-" interface in their drivers. Is it the same as Nvidia in 
that their proprietary drivers don't support it at all? Do they have 
any kind of interface for controlling all of the extra goodies on 
their boards with their drivers? I've never looked at their 
proprietary drivers.

Thanks

Will
