New subject: PECI temperature in lm-sensors

23 Jan 2017


      I'm sure that I have only one chip, I just don't know how to enable PECI
monitoring in it:

In my case sensors-detect found one SuperIO the first time I ran it, but
there was a second one "hidden" in a i2c chip, each one provide different
information. In the end I had two kernel modules loaded instead of only one
previously.

Hi!
No, "sensors-detect" founds my SuperIO and needed kernel module is installed
in system correctly.
The problem is in "sensors" command. It displays all voltages and pch
temperatures correctly, except of PECI temperature from CPU, PECI agent temp
is always zero.

Hi,
Had a similar issue on a KCMA-D8. When running sensors-detect you have to
force probing of i2c chips (default choice is "NO" if you just press enter
when asked) then hopefully with one of them it will detect other sensors.
Hope this helps

Does someone have any experience with enabling PECI monitoring on nuvoton
SuperIOs ?
I'm trying to enable it on board with Haswell+Lynxpoint CPU and  NCT6776
SuperIO.
But all I see in lm-sensors output for now is zero temperature for PECI
Agent.
Does coreboot have any SuperIO chips/Intel CPUs/motherboards, that have this
functional enabled? What is usually need to be done to enable PECI
monitoring?
