ITE8712F-A Beta Test (Examined/Solved - lm_sensors 2.6.0, Linux 2.4.6 (from kernel.org))

[contact]

Hello,

First of all, thank you for writing these drivers and shring them with the

general public.

This is not so much a bug report as a beta test -- I had read earlier posts

that

said the ITE 8712 was not well tested.

I have one of those cheapo Bk-i810 "Book PC"s based in the Intel i810 chipset

and it has an ITE 81712 sensor chip. It used the "i2c-i810" interface and is

accessed via the ISA bus. "lsmod" shows:

i2c-core 13328 0 [lm78 i2c-isa i2c-dev i2c-proc i2c-algo-bit]

In this _BIOS_ the systems reports:

Vcore Voltage 1.72V

+3.300V 3.50V

+5.000V 5.18V

+12.00V 11.64V

CPU Temp 38C

System Temp 32C

CPU Fan 5443RPM

sensors reoprts:

it87-isa-0290

Adapter: ISA adapter

Algorithm: ISA algorithm

in0: +1.76 V (min = +1.53 V, max = +1.87 V)

in1: +1.85 V (min = +2.25 V, max = +2.75 V) ALARM

in2: +3.50 V (min = +1.48 V, max = +1.80 V) ALARM

in3: +2.59 V (min = +2.68 V, max = +3.26 V) ALARM

in4: +2.97 V (min = +2.84 V, max = +3.45 V)

in5: +2.09 V (min = +1.50 V, max = +1.82 V)

in6: +1.68 V (min = +0.81 V, max = +0.97 V)

in7: +1.24 V (min = +2.68 V, max = +3.26 V)

fan1: 5532 RPM (min = 3000 RPM, div = 2)

fan2: 0 RPM (min = 3000 RPM, div = 2)

fan3: 0 RPM (min = 3000 RPM, div = 2)

temp1: +30.0C (min = +20C, max = +60C)

temp2: -92.0C (min = +20C, max = +60C)

temp3: +42.0C (min = +20C, max = +60C)

vid: +0.00 V

temp2 seems to be the CPU temp because it varies quickly with load.

temp3 I think is System Temperature -- I'm not sure.

in0 seems to be Vcore

in2 seems to be 3.3000V lead

fan1 is the CPU fan and it dead accurate.

I can't map what the rest are.

If I insmod the lm78 driver so that lsmod says:

Module Size Used by

lm78 6944 0 (unused)

i810 75536 1

agpgart 14832 7 (autoclean)

i2c-core 13328 0 [lm78 i2c-isa i2c-dev i2c-proc i2c-algo-bit]

sensors then reports:

lm78-isa-0290

Adapter: ISA adapter

Algorithm: ISA algorithm

VCore 1: +1.76 V (min = +0.00 V, max = +0.67 V)

VCore 2: +1.84 V (min = +0.00 V, max = +0.00 V)

+3.3V: +3.50 V (min = +2.97 V, max = +0.00 V) ALARM

+5V: +4.35 V (min = +4.50 V, max = +5.48 V)

+12V: +11.29 V (min = +10.79 V, max = +13.11 V)

-12V: -7.27 V (min = -10.78 V, max = -13.18 V)

-5V: -2.53 V (min = -4.50 V, max = -5.48 V) ALARM

fan1: 0 RPM (min = 6000 RPM, div = 1)

fan2: 45000 RPM (min = 6000 RPM, div = 1)

fan3: 4090 RPM (min = 3000 RPM, div = 2) ALARM

temp: +75.0C (limit = +60C, hysteresis = +50C) ALARM

vid: +3.50 V

alarms: Board temperature input (usually LM75 chips)

alarms: Chassis intrusion detection ALARM

It is a lot more accurate. When compared against the BIOS:

* +5V seems to be off a little

* I can't tell which one is the CPU fan -- they all seem to be way off.

* CPU temp seems to be about double what it should be.

Well, I hope that this helps in debugging the new it87 driver. If there is any

more information that I can supply that would help please let me know. If you

would like me to do any beta tests also let me know.

Once again, thanks for writing these drivers.

Sincerely,

Chris Gleba

(cgleba@…) --- Thanks for the report.

We'll put it to use when we can find the time!

If you have any other info email sensors@….
