PostPosted: Thu Dec 02, 2004 1:09 am    Post subject: no i2c devices Reply with quote

I have an Asus A8V Deluxe motherboard (w/ athlon64 3500+ skt939), and also a spare machine with a K8V Deluxe motherboard (w/ athlon64 3400+ skt754). I can't get lm-sensors working on either.

I correctly compile all the i2c stuff as modules; i install lm-sensors and it compiles cleanly against the kernel; I've done everything to the letter, but when I run sensors-detect, it says:

Code:
No i2c device files found. Use prog/mkdev/mkdev.sh to create them.


I follow the adivce of modprobe'ing i2c-dev, the module loads, but sensors-detect then produces the same error. No matter what I do I can't seem to get these i2c devices to be created in /dev/ or /sys. I even try modprobing various i2c modules and i2c-dev and then restarting coldplug/hotplug, but to no avail.

I have the latest bios version for my A8V, and a recent (haven't checked) bios version on my K8V.

Does anyone know what might be causing this problem?

This sounds like you are using udev instead of devfs?

Did you try running the mkdev.sh script? The entries under /dev are made using mknod, not by loading modules into the kernel (although that is still required).

See my earlier post in this thread for that script or find in in the lm_sensors tarball.

you should try running the mkdev.sh script that you can find this way.
Code:

tar -xvvzf /usr/portage/distfiles/lm_sensors-2.8.7.tar.gz
./lm_sensors-2.8.7/prog/mkdev/mkdev.sh


and after you should be able to get you sensors info using
Code:
sensors

thanks man, fixed the problem! I was getting even more confused because my other skt754 athlon64 machine suddenly aquired i2c devices after a reboot and I couldn't figure out what I'd done - ah the mysteries of linux hardware configuration =)

Didn't have time to read the thread in it's entirety, but managed to get sensors working on my MSI nForce3 Neo2 Platinum with the following modules loaded at boot (all found under I2C settings, using 2.6.10-gentoo-r6 sources);

i2c-dev (should already be loaded with alias char-major-89 in /etc/modules.d/aliases)
i2c-nforce2
w83627hf (module for the winbond chip)
i2c-sensor
i2c-isa
it87 (not sure if this is needed, but it was sensors-detect's next best guess)

The sensors data is made over the ISA bus, so you'll need to ensure you have ISA support in order to build the i2c-isa modules.

Code:
tybalt linux # sensors
w83627thf-isa-0290
Adapter: ISA adapter
VCore:     +1.46 V  (min =  +0.70 V, max =  +1.87 V)
+12V:     +12.65 V  (min =  +4.80 V, max =  +1.40 V)
+3.3V:     +3.17 V  (min =  +1.02 V, max =  +1.10 V)
+5V:       +4.99 V  (min =  +2.72 V, max =  +3.55 V)
-12V:     -14.91 V  (min = -14.91 V, max = -14.91 V)
V5SB:      +4.92 V  (min =  +1.83 V, max =  +5.48 V)
VBat:      +2.61 V  (min =  +0.56 V, max =  +2.37 V)
fan1:     5037 RPM  (min = 12053 RPM, div = 2)
CPU Fan:     0 RPM  (min =   -1 RPM, div = 2)
fan3:        0 RPM  (min = 8881 RPM, div = 2)
M/B Temp:    +16 C  (high =   +86 C, hyst =   +17 C)   sensor = thermistor
CPU Temp:  +33.5 C  (high =   +80 C, hyst =   +75 C)   sensor = PII/Celeron diode
temp3:     +24.5 C  (high =   +80 C, hyst =   +75 C)   sensor = thermistor
ERROR: Can't get VID data!
alarms:
beep_enable:
          Sound alarm disabled


Still some tweaking to do, but thought it might be helpful (although someone has prolly posted it already, damned search...!) cos google didn't turn much up either.

Now I just need to get Cool'n'Quiet working properly...
Code:
powernow-k8: vid trans failed, vid 0x3, curr 0x4
powernow-k8: transition frequency failed

:roll:

Hi,

I have udev inplace and set the kernel properly (ver 2.6.9-r13).
When I type sensors I get this error:

Code:
# sensors
Can't access procfs/sysfs file
Unable to find i2c bus information;
For 2.6 kernels, make sure you have mounted sysfs and done
'modprobe i2c_sensor'!
For older kernels, make sure you have done 'modprobe i2c-proc'!


Here is my fstab (important part)
Code:
none                    /proc                   proc            defaults                        0 0
none                    /dev/shm                tmpfs           defaults                        0 0
none                    /proc/bus/usb           usbdevfs        defaults                        0 0


In lsmod I do not have any i2c modules.
I think the issue has to do with udev and the fact that lmsensors is looking for sysft and is not there.

I really do not know what to do and what command to run. I need lmsensor because I have to monitor the cpu temperature. I do not know how to handle i2c bus info, modprobe.

Could someone kindly help me? I need assistance.

I appreciate your help.
Spiro

Well, is your udev working generally ?
You have to set RC_DEVICES="udev" in /etc/conf.d/rc !
And emerge udev, o'course...
If those are in order, sysfs will be mounted/run by the kernel automatically (it is not a FS you can control yourself).

Hi adaptr,

You are correct. I made changes to the /etc/conf.d/rc file and here is what I currently have:
Code:
RC_TTY_NUMBER=11
RC_PARALLEL_STARTUP="no"
RC_NET_STRICT_CHECKING="no"
RC_DEVICES="udev"
RC_DEVICE_TARBALL="no"
RC_DEVFSD_STARTUP="no"
RC_RETRY_KILL="yes"
RC_RETRY_TIMEOUT=1
RC_RETRY_COUNT=5
RC_FAIL_ON_ZOMBIE="no"
svcdir="/var/lib/init.d"
svcmount="no"
svcfstype="tmpfs"
svcsize=2048


Obviously, udev was already implemented but missconfigured.
I rebooted the system but no way to run sensors = "No sensors found!"

Here is my lsmod:
Code:

Also, ls /sys/bus/i2c/devices/ returns tha is empty. This is wrong, right?

What should I do?

Please advice....

Thank you,
Spiro

Did you do "make modules_install"?

Hello,

I'm a Slackware user (not looking for flames here, just to see if I can help) and have installed i2c from scratch. There are a lot of complaints about what doesn't work, etc. So, here's my steps to get it work (at least to verify things exist). Missing any one of these steps, nothing will work.

Gentoo for sure works differently, but you can verify the equivalent steps.

1. the easy part - download and install the package that includes you `sensors` and `sensor-detect`.

2. do some research on your motherboard, etc. And compile your kernel. For example, my board uses an IT8705F chip on a VIA8237 chipset, so I enabled the these kernel features: i2c-core (compile-in), i2c-dev (module), i2c-viapro (module), i2c-isa (module), i2c-eeprom (module), i2c-sensor (module), it87 (module). Also make sure you enable sysfs - compile it in, copy the kernel, blah blah blah, the usual steps. Don't get too excited and forget lilo if you use it ;)

4. Create a mount point for sysfs, and tell the box to mount it automatically: mkdir /sys, edit your /etc/fstab to add this line: "sysfs /sys sysfs defaults 0 0"

5. Also make sure a /dev node is created for your i2c device. This command worked for me. "mknod /dev/i2c-0 c 89 0". See the man page of mknod for details.

6. Reboot and modprobe all the modules needed. Proceed to run sensor-detect and then sensor.

Hope it helps!

Hey hey!

I have posted this question in details there:
http://forums.gentoo.org/viewtopic.php?p=2688069#2688069

To be short, the sensors-detect tool "told" me that I needed those modules :

Code:
i2c-core (ok)
i2c-savage4 (ok)
smartbatt (!!)
max6650 (!!)
saa1064 (!!)
lm92 (ok)
ds1621 (ok)
eeprom (ok)
smbus-arp (!!)
pca9540 (!!)


some modules are loading OK while others DON'T. It would be fun for me to compile them in my kernel, only if I could find them! Where am I going to find support for those modules :

    smartbatt
    max6650
    saa1064
    smbus-arp



HELP!! I really need to get my sensors working because this will be a prod server

Anyone know where gkrellm2 is picking up the nvidia gpu ambient and core temps from? For example, I know my motherboard/cpu are located in /sys/bus/i2c/devices. But I been searching for quite a long time and can't locate the gpu. Anyone have any idea?

thanks!

EDIT: well, I never did find that file, but if anyone else was wondering, I was able to gleen the info by using nvidia-settings at the cli and sed the info I wanted for my .torsmorc.

can i use gentoo-sources kernel?
after emerging lm_sensors (with that kernel) kacpid goes on 99,9% of cpu... do i need to emerge even i2c? (in the italian guide it says to emerge i2c before lm_sensors)
thanks!

When emerging lm_sensors at a system which has /usr/src/linux pointing to a 2.6 kernel the lm_sensors package just installs userspace applications, as the kernel modules have been merged into vanilla-sources. I²C has been merged too, so you don't need the package.

I got the hardware sensors on my Abit KN8-SLi board to work (Winbond W82867HF chip) but it has the nasty habit of shutting fans it monitors off AND then breaking the "system shutdown when a fan dies" routine. I'd like to run lm_sensors but I certainly don't want to see a repeat of my CPU heatsink fan suddenly shutting off and the core temp going from 44 C (full load on both cores of an X2 4200+) to 121 C and the computer not shutting off on either the HSF failure or temp > 70 C like the BIOS is supposed to have it do. I uninstalled lm_sensors and compiled a new kernel without i2c and sensors and the fans run and the system shuts off as it is supposed to upon a fan failure.

Any suggestions?

I had the same problem.
Try disabling ACPI sleep states in kernel config. Maybe that will help.

Hi! I already configured everything on my computer for sensor reading. Now I am looking for a non-gui app that can periodically check temperatures and shut down the system if it's too hot. I found a lot of apps that run under X (gkrellm2, conky, various gnome, kde and X apps...) but no text-only ones. Do you have any suggestions? Thanks a lot
