pwmconfig acpi vs. hwmon, no fancontrol config

rh — 2013-05-25T23:39:57

The pwmconfig doesn't find the fan device but I can echo commands
to get the cpu fan to stop and start.  Haven't been able to do anything
with the chassis fan.

When I run pwmconfig it reports "no correlation" and I don't get
a fancontrol cfg file. I edited the pwmconfig to look at acpi first
instead of hwmon and there's no difference.

The w83l786g seems to have some kind of watchdog on it as well but
not sure what this means. But while I was trying to sort out the fans
the system crashed. I found that the watchdog detected something and
decided to reboot. I am going to build a 3.9.4 kernel for the watchdog
issue but I don't think it's related to fan problems.

adequate :)

Thanks again for the useful information.  Looking through dmesg you are 
probably right since I am getting an ACPI error shortly after the it87 
driver loads, as shown below:

I may be missing something, but my understanding is that the chip
has an embedded microcontroller (EC) which handles the actual fan
control. While the chip data sheet describes the hardware accessible
to the EC, and the API between CPU and EC, it does not describe
the logical interface between the two. Problem is that this
interface is not well defined and depends on the microcode
running on the EC.

The file referenced above seems to provide that information for the
specific board and for the microcode running on the EC in that board
(which appears to be the referenced 'quanta' firmware). That does
not mean, however, that it would be the same for other boards,
including yours.

A second potential problem is that the ACPI data provided above suggests
that the EC may be controlled through ACPI, which means that ACPI most
likely reserves the memory space needed to access the controller.
If this is the case in your system, which is quite likely, your best
option would be an ACPI driver.

Thanks,
Guenter

They do look close enough after reading the datasheet for each. 


I tried this and sensors-detect produces the same output.
It seems I don't need to rely on sensors-detect though and
need to find out why pwmconfig cannot control the fans.

But it's another guess. I did see that in the 3.9.2 kernel there's
a separate flag for PWM that I had never noticed before. I think
it's new. I checked the box for that.

I just want to have fan control and it seems all the pieces are there
but something's missing.  It could be PEBKAC but I've looked at a
lot of stuff....the vx800 spec, the W83l786NG,NR,G,R datasheets,
linux/Documentation/hwmon, thermal, etc., etc.

And? PCI is a system bus. The value is retrieved over the PCI bus.
That's all it means, really.


Did you actually try loading the it87 driver? Did it work? If not, you
may be another victim of ACPI:

ITE IT8518E supported in coreboot, helpful?

Santi Villalba — 2013-05-24T09:47:55

This controller is giving people some trouble, as it is shipped in more 
and more laptops [1] and the fans can become quite annoying in these 
systems.

In the past it was said that the main problem was the lack of a 
datasheet from ITE [2]. Recently there has been progress from the 
coreboot projects getting the info for quanta firmware on IT8518 [3]. 
Can this particular file help with the lack of specs or it depends on 
other factors?
http://review.coreboot.org/gitweb?p=coreboot.git;a=blob;f=src/ec/quanta/it8518/acpi/ec.asl;h=7549fa283da69b9b1fca8589b1fc7f59fd30f7a4;hb=7e568559634199668859b7c662aea7f6b41f3920

In my particular case, I have a noisy clevo p150em. I can help providing 
testing and perhaps developing - just looking at the code of other 
modules, it87, it seems to me I could give a hand beyond testing.

Thanks

What does "sensors" return?


It is there indeed.


Should't matter, while the chips aren't 100% compatible they have the
same chip ID so the same driver supports both.


This is your W83L786G chip. sensors-detect would tell you if the driver
was built as a module rather than embedded in the kernel.

I have improved sensors-detect so that it can handle monolithic kernels
better. Please give it a try and report the output:

lm-sensors help question

Bruce Kettle — 2013-05-24T03:40:27

Hi I have a Biostar a780l3g motherboard with a Phenom II 840 processor.  
I have Ubuntu 12.04 32-bit installed and current patches (kernel 
3.5.0-30-generic).  I installed lm-sensors and ran sensors-detect, it 
properly detected the k10 sensors.  But when I run sensors the output is 
as follows:

bruce< at >bruce-A780L3G:~$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:        +32.0°C  (crit = +127.0°C)

k10temp-pci-00c3
Adapter: PCI adapter
temp1:        +23.5°C  (high = +70.0°C)
                        (crit = +90.0°C, hyst = +88.0°C)

I was hoping to be able to read core temps, but I don't think either of 
these are that.

It does not appear that Biostar provides Linux chipset drivers, although 
your FAQ indicates this should be supported in this version of the 
kernel.  Is there something I am doing wrong or is the board just not 
supported?  The sensors did work in Windows 7 in a variety of programs, 
so I don't think there is a hardware issue.

Thanks

W83L786G not detected on vx800

rh — 2013-05-24T10:21:29

Hello,

On the MB there is a winbond W83L786G but it is not detected
by sensors-detect.  The  kernel is monolithic (i.e. no modules)
and it is linux3.9.2.

It seems that lmsensors is unable to see this device but it is there.

cat /sys/class/hwmon/hwmon1/device/name
w83l786ng

As I said the actual device is a w83l786g

Tips/pointers/suggestions much appreciated as the fans are
running at ~80% all the time.

[PATCH v3] hwmon (ds1621): Remove detection function

Robert Coulson — 2013-05-23T16:22:22

Due to a lack of device and vendor identification registers, the
Dallas/Maxim DS16xx devices cannot be uniquely detected, sometimes
resulting in false positives. Therefore, the detection function is
being removed in favor of explicit device instantiation.
