Hello Lonni, Thanks for the quick answer. I'm not the person who seeks the help but users which do seek help from me. I'm the member of lm-sensors group that develops and maintains the sensor drivers for the Linux kernel. There is the unified infrastructure for sensors handling and drivers for monitoring chips. This unified infastructure means that any application can be used to access the sensors data which are exported to user programs. Making it closed and locked just to one apps may not fit the user needs at all. Just imagine the user has some favourite application like gkrellm and wants to see the GPU temp there. Opening the drivers for i2c access will enable you to use our hwmon drivers for chips commonly found on the graphics cards. This would mean it would reduce you the time to develop the driver to access the chip on your own. Moreover, we are taking care of that the drivers will work nice in any future linux version. Some companies like Asus, Tyan and Winbond are working with us tightly on this sensors field. If you want to join the cooperation, I'm offering help to nVidia whith opening the drivers for i2c bus and integrating them to the kernel. Please forward this email to the responsible manager, or if you need more information contact me directly, or via the lm-sensors mailing list. Thank you, Regards Rudolf
