Hello everyone,
It seems the cpu temperature of the VIA EPIA ML6000EAG chip vt1211
seems to be a bit off in
sensors version 3.1.2 with libsensors version 3.3.2.
The CPU is a VIA Nehemiah with a passive cooling setup.
All tests happend at approx. 20 degree celsius with no active cooling
inside the case.
Here is some hopefully relevant data:
/etc/sensors3.conf
snipped:
chip "vt1211-*"
label in5 "+3.3V"
label temp2 "SIO Temp"
#compute temp1 (@*@*0.0046) - (@*0.088) - 0.748, (@*0.9686) + 65
#compute temp1 (@ - 65) / 0.9686, (@ * 0.9686) + 65
#kernel.org on C3 Ezra
compute temp1 (@ - 83.869) / 0.9528, (@ * 0.9528) +83.869
# sensors
vt1211-isa-6000
Adapter: ISA adapter
in0: +1.95 V (min = +0.00 V, max = +2.63 V)
in1: +1.99 V (min = +0.00 V, max = +2.63 V)
in2: +1.03 V (min = +0.00 V, max = +2.63 V)
in3: +1.97 V (min = +0.00 V, max = +2.63 V)
in4: +2.12 V (min = +0.00 V, max = +2.63 V)
+3.3V: +3.33 V (min = +0.00 V, max = +4.18 V)
fan1: 0 RPM (min = 0 RPM, div = 2)
fan2: 0 RPM (min = 0 RPM, div = 2)
temp1: +34.8 C (high = +179.6 C, hyst = -88.0 C)
SIO Temp: +56.0 C (high = +204.0 C, hyst = +0.0 C)
cpu0_vid: +1.750 V
this output is generated with the above compute value.
the raw value for the temperature are as followed:
# cat /sys/devices/platform/vt1211.24576/temp*_input
117000
56000
this is with a cpu load of <5 percent.
with approx. 100 % cpu load the temp1 value increases slightly to 121000.
I did try to find additional info for the modul , settings for the
sensors3.conf and came up with the 3 above mentioned compute values.
As they seem to be for a different processor im not sure if those values
are correct for my system at all.

please let me know if i can give additional information to help solving
this "problem".
with regards
Dennis Nolte
