Kernel module missing, how to proceed?

Hi,

I'm trying to use lm_sensors, but it doesn't detect any chips.

During the process, I've noted something weird:

"sensors-detect" (svn) detect the use of  the "i2c-sis96x" driver.
Confirmed by "lsmod | grep i2c"

[root@nodrom eko]# lsmod | grep i2c
i2c_dev                 6148  0
i2c_sis96x              4996  0
i2c_core               20352  3 i2c_dev,nvidia,i2c_sis96x

But regarding the "lspci", I have to use the i2c-sis645 module!

[root@nodrom eko]# lspci
00:00.0 Host bridge: Silicon Integrated Systems [SiS] SiS645DX Host & Memory & AGP Controller
00:01.0 PCI bridge: Silicon Integrated Systems [SiS] Virtual PCI-to-PCI bridge (AGP)

00:03.3 USB Controller: Silicon Integrated Systems [SiS] USB 2.0 Controller
00:04.0 Ethernet controller: Silicon Integrated Systems [SiS] SiS900 PCI Fast Ethernet (rev 90)

02:00.0 Network controller: RaLink RT2500 802.11g Cardbus/mini-PCI (rev 01)

Of course, "modprobe i2c-sis645" isn't working: the /lib/modules/2.6.22-ARCH/kernel/drivers/i2c/busses/i2c-sis645.ko doesn't exist!

[root@nodrom eko]# modprobe i2c-sis645
FATAL: Module i2c_sis645 not found.

So, I think that I'm currently using the wrong kernel module.  How could I use the i2c-sis645 instead?

This is maybe a dumb question, but I'm not familiar with the kernel related-stuff...

Thanks in advance.

Re: Kernel module missing, how to proceed?

00:02.1 SMBus: Silicon Integrated Systems [SiS] SiS961/2 SMBus Controller

That's the one. And looking at the name I'd say the module is i2c-sis96x.

Shame on me.
Thanks anyway!

Re: Kernel module missing, how to proceed?

Ok, I'm sorry to insist, but I found an interesting post:

http://linuxagora.com/libranet/viewtopi … 69e1#41183

This guy as a pretty similar configuration, and finally got lm_sensors working.

And, seen on the lm_sensors site:

Kernel driver `i2c-sis645.o'
2    
Status: Beta
   
Supported adapters:
  *Silicon Integrated Systems Corp (SiS)
    Any combination of these host bridges:
    645, 645DX (aka 646), 648, 650, 651, 655, 735, 745, 746
    and these south bridges:
    961, 962, 963(L)

So...?

I must admit that I'm lost in all this information, and I'm not familiar with hardware in general.
So, if someone could explain this situation, it'll be friendly.  Is the i2c-645.o module obselete, or something like that?

Thanks.

Re: Kernel module missing, how to proceed?

Yes, the i2c-sis645 module was for the now obsolete 2.4 kernel series.

From kernel sources linux-2.6.22.9/Documentation/i2c/busses/inc-sis96x :

Kernel driver i2c-sis96x

Replaces 2.4.x i2c-sis645

Supported adapters:
  * Silicon Integrated Systems Corp (SiS)
    Any combination of these host bridges:
    645, 645DX (aka 646), 648, 650, 651, 655, 735, 745, 746
    and these south bridges:
        961, 962, 963(L)

Author: Mark M. Hoffman <mhoffman@lightlink.com>

So i2c-sis96x is the correct module, but for some reason lm-sensors is not showing any sensors on your system.

Do you have acpi / acpid installed ?

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

(A works at time B)  && (time C > time B ) ≠  (A works at time C)

Re: Kernel module missing, how to proceed?

Hi,

First, thanks for your response.
Yes, I've acpi installed, and acpid running at boot. (Even if didn't configure anything... is it normal?).

Here are some outputs:
