Wrong values from sis5595 on Jetway J-530BF (Examined/Solved - lm_sensors-2.5.5/Mandrake-2.2.17-21mdk-A)

1) All voltages values out. Bios shows 2.25 and 3.41 for cpu voltages. It also

monitors +5v and +12v. Possibly vcore1 is +12v (x4) but others dont match!

e.g.,

wdk@Ralph ~ $ sensors

sis5595-isa-0290

Adapter: ISA adapter

Algorithm: ISA algorithm

VCore 1: +3.02 V (min = +2.84 V, max = +3.45 V)

VCore 2: +2.89 V (min = +2.68 V, max = +3.26 V)

+3.3V: +2.04 V (min = +2.97 V, max = +3.63 V) ALARM

+5V: +2.25 V (min = +3.78 V, max = +4.62 V) ALARM

fan1: 4591 RPM (min = 3000 RPM, div = 2)

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

temp: +127.0C (limit = +50C, hysteresis = +60C)

alarms: Board temperature input (usually LM75 chips)

2) Temperature. Note value above is a fixed, never varying +127c.

The sis5595 documentation shows that the register address is 0x24, whilst the

./kernel/chip/sis5595.c file has it as 0x27. When changed, this returns the

following which does vary inversly with temperature when tested via changing the

airflow.

temp: -32.0C (limit = +50C, hysteresis = +60C) ALARM

alarms: Board temperature input (usually LM75 chips)

From reading the docs, it appears that the temp input is just another voltage

detector similar to the others, but I cannot find in the Jetway docs what its

using to generate a temperature related vin. --- We recently changed the driver to support the new temperature

register location.

There are two versions of the chip, the old version has the temp.

in a different location.

Pull the new version from CVS and let us know how it works.

The output of (as root) lspci -xxx for the device would also

be helpful.
