where the tar is it?

I modprobe ic2-core and ic2-i801 and ic2-dev
but I don't get the functionality of ic2-proc.

I'm using kernel 2.6.7 and want to monitor my expensive new hardware
but cant locate the /proc/bus/ic2 tree after loading the modules.

any ideas?

Try i2c

ok wiseass!

here is the relevant dump from my system (

linux:~/xrm> lsmod | head
Module Size Used by
i2c_i801 8300 0
i2c_dev 10400 0
i2c_core 24544 2 i2c_i801,i2c_dev
ppp_deflate 6432 1
zlib_deflate 22904 1 ppp_deflate
zlib_inflate 22848 1 ppp_deflate
bsd_comp 6240 0
ppp_async 12160 1

See, all three modules are loaded

linux:~/xrm> ls -l /proc/bus
total 0
dr-xr-xr-x 2 root root 0 2004-08-23 14:15 input
dr-xr-xr-x 6 root root 0 2004-08-23 14:15 pci
drwxr-xr-x 6 root root 0 2004-08-23 08:32 usb

linux:~/xrm> dmesg | tail -3
PPP BSD Compression module registered
PPP Deflate Compression module registered
i2c /dev entries driver

so, where in the hell is the (I2C)-proc entry? Even a find
on the /lib directory doesn't locate a module that provides

Is it broken, depricated, or just plain not documented well
enough (as is the case with far too much opensource software)?

ok dumbass

Its not in the latest kernels from what I see,so if lm_sensors
does not load it at config why do you need.Check lm_sensors web
site and see if the latest version need it.

It doesn't show up in /proc/bus
But it should in /sys
What does the sensors command say ??

Kirth Gersen < XXXX@XXXXX.COM > tried to express:

sensors-detect crashes, looking for /proc/bus/i2c

Once the three modules (core, i801, and dev) are loaded I
checked both /proc/sys/dev and /proc/bus...

no i2c or sensors entries are found.

I'm running linux- and lmsensors is the version
supplied with Suse 8.1

On my box, MSI KT3 mobo, and Linux 2.6.7 sensors-detect does not
work either. It tells me to run a script to create all kinds of devices.
I forgot to do just that.

Anyhow, inspectection of my mobo told me what sensor chipset is
used and that was all I needed, generating the proper kernel with
the proper modules, rebooting and afterwards a

modprobe -a w83781d

and issueing the command:


simply works.

Don't know how old Suse 8.1 is but you should use the latest
stable lm_sensors version, currently 2.8.7 I believe.
