Looking at the prtconf output from the T1/200 and the SB-1000 (for which the
bbc_envctrl driver was written), it is clear no current driver will support
this environmental monitoring implementation.  However, if you simply want the
CPU temperature you should be able to use the LOM console to retrieve this
information, independent of the host OS (though Solaris may be required for
initial LOM configuration).  For anything more, you'll likely have to wait
until a developer gets a hold of the hardware and decides to take a try.

Correct.  The T1/200 has an "i2c" node.  This goes back to my comment about
the driver needing to understand the OBP nodes associated with environmental
monitoring.

I don't think that's important; all I want is the CPU temperature.

Umm, the Netra T1 doesn't have an "envctrl" -- or a "SUNW,rasctrl" on an
ebus.

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).
