[lm-sensors] W83667HG-B testing

[Tobias Preclik]

Hi,

my Zotac board H55-ITX features the W83667HG-B chip. I downloaded and
compiled the standalone kernel module today. Here's the sensors output:

The module loads fine:

Any more information desired?

Actual values look mostly good, but the limits are really off.
Difficult to say, though, if those are wrong readings or just badly configured.

Jean, any idea/thoughts ?

Only a register dump would say from sure. But given that the alarm
flags all match out-of-limit readings, I would be inclined to say these
are only misonconfigured limits. Tobias could set proper limits and
check that all the alarms go away.

The only inconsistency is with temp3... the reading is out of limit but
there is no alarm flag. You may want to double check the datasheet to
ensure that the driver reads both the temp3 value and its alarm flag
from the right register/bit.

Yes, you are right - that looks suspicious and is inconsistent.
I'll have a look into the spec.

I checked the specification. Registers are the same for both chips,
unless I am missing something. No idea what is going on.

I seem to remember that on some of these chips, in6 and temp3 are
mutually exclusive? So you may have to check all the configuration
registers which determine which of in6 or temp3 is enabled. Maybe in6
is enabled and the driver wrongfully think temp3 is instead?

Just a random idea, I may be completely off the track.

The detection code seems to be fine - at least I didn't find a problem
with it. Unless, of course, the bit value to enable aux temp monitoring
was reversed in rev B, but the manual doesn't reflect that.

Guess I _must_ be missing something, but right now I have no idea what
it might be.

One thought - Tobias, can you provide sensor output from your BIOS for
comparison ?

These are all PC Health informations I could find in the BIOS:

CPU Temp = 49°C
CPUFAN = 1692 RPM
Vcore = 1.232V
3VCC = 3.360V
VTT 1.1V = 1.120V
PCH Voltage = 1.096V
IGD Voltage = toggles between 1.176V and 1.184V
VSB = 3.280V
VBAT = 3.344V

The voltages are rather hard to match aren't they?

Hope this helps.

Tobias

I did some research on the web. Looks like temp3 almost always shows
very low temperatures for the W83667, and also for w83627ehf. Also, since
the reading is low, but there is no low limit, there isn't really a reason
for raising an alarm. 

Also, min/max values for voltages seem to be off almost everywhere.
And values for temp1_max and temp1_hyst are often negative or very low.

So, in summry, looks like -B support is just as good or as bad as support
for the other chips. Not sure if that is good or bad, though, since the 
off-track readings are so common.

These chips simply don't initialize the limits to anything sane by
default. It's the user's (or BIOS') job to write sane limits. This
doesn't mean anything about the driver.

Off-track reading are "fine" as long as the alarm flags match.

Not at all. in1 is VTT 1.1V (+1.11 V vs 1.120V). in2 and in3 are 3VCC
(+3.36 V vs 3.360V, hardwired so can't be wrong.) in4 is PCH Voltage
(+1.10 V vs 1.096V). in5 is IGD Voltage (+1.18 V vs 1.176V/1.184V). in7
and in8 are VSB and VBAT respectively (values match perfectly and they
are internally wired too.)

The remaining pair is in0 for Vcore. The different value can be
explained by your BIOS running the CPU at its max frequency while Linux
runs it as a lower frequency (and voltage is scaled down at lower
frequencies.) This also explains the different CPU temperature (most
probably temp2) and fan speed (fan2), assuming there is some form of
automatic fan speed control in place.

The BIOS doesn't show any value which Linux doesn't, so I'd say we are
fine. And you can use the following as your configuration file:

chip "w83667hg-isa-0a10"

   # Voltages

   label  in0 "Vcore"
   label  in1 "Vtt"
   label  in2 "AVCC"
   label  in3 "+3.3V"
   label  in4 "PCH"
   label  in5 "IGD"
   label  in7 "3VSB"
   label  in8 "Vbat"

   set in1_min  1.1 * 0.95
   set in1_max  1.1 * 1.05
   set in2_min  3.3 * 0.90
   set in2_max  3.3 * 1.10
   set in3_min  3.3 * 0.90
   set in3_max  3.3 * 1.10
   set in4_min  1.1 * 0.95
   set in4_max  1.1 * 1.05
   set in7_min  3.3 * 0.90
   set in7_max  3.3 * 1.10
   set in8_min  3.0 * 0.90
   set in8_max  3.0 * 1.10

   # Fans

   ignore fan1
   label  fan2 "CPU Fan"
   ignore fan3
   ignore fan4
   ignore fan5

   set fan2_min  800

   # Temperatures

   label  temp1 "M/B Temp"
   label  temp2 "CPU Temp"
   ignore temp3

   set temp1_max       55
   set temp1_max_hyst  52

I'll add it to the wiki now for reference.
