There isn't anything done for this already in Linux, but the temperature
sensors are read in the test suite when the code runs directly on the PPCs
without the Linux layer. The monitors are on the I2C bus, for which there is
a software IIC interface connected to the Linux PLB bus so you can probably
twiddle the necessary memory space in software to get to the info that you
want.

Henry's probably the right man to ask, but I think the temp sensors are
on an I2C bus. If the PPC has access to that bus, and there is a Linux
driver available, then you could use something like lm-sensors.
I believe this will be the approach with ROACH.

Hi Billy,
I’m not sure, I’m cc’ing Jason Manley and Henry Chen, who might know.

Hi Dan / Andrew,
Is there code available for reading the BEE2 user FPGA temperature
sensors within the standard BORPH OS?
We're worried about MTBF of the fans and want a way to log & look for
indications of failure. Would this be a software item, or something
that might be in gateware?
Thanks,
Billy
