On a Netra t1 105, it is possible to use the envctrl kernel module to read the CPU temperature. Is this possible with a Netra T1 AC200?Not currently.What needs to be done to adapt the driver?
A driver needs to learn about the OBP format used on a particular platform for environmental monitoring. In the case of the T1/200 it may be similar enough to the existing bbc_envctrl driver (written for an SB1000) that you can adapt it for use on your system. At the very least, you'll have to remove the bbc_present() test.
If you want temperatures available to userspace, additional modifications will be required as well. I believe the current bbc_envctrl driver monitors, but does not export, this information.
If you are interested in doing this work I suggest you post to the development list (ultralinux@vger.kernel.org).
