I have a Texas Instrument Tmp75 installed on the smbus (Intel LynxPoint PCH). I have installed the following drivers:
i2c-i801.c (make and make install)
lm75.ko (sudo insmod lm75.ko)
I have ran "sensors" but it still cannot see my chip. I have also installed your i2c-tools but when I run i2cdetect -l, it does not detect my smbus. What drivers and/or files am I missing here?

Did you run modprobe i2c-i801 ?

Also worth checking:
* Is i2c-dev loaded? i2cdetect needs it.
* Errors in the kernel log after loading the i2c-i801 driver. For
example ACPI resource conflicts could be a problem.
* Kernel version. The original LynxPoint PCH is only supported since
kernel 3.4, for the LP flavor you need something even more recent. If
you use my standalone version you should be fine.

Guenter,
Yes. Both lm75 and i2c-i801 appear when I run lsmod both of them are listed as shown below ...
Module Size Used by
lm75 13435 0
i2c-i801 18136 0
I also noticed that under /dev, I do not see any i2c* devices at all.
By the way, I am using Fedora with kernel 3.11.1.200.fc19.x86_64. Thank you, Guenter.

Jean,
Loading I2c-dev made it so it sees i2c-0 to 12c-6 using i2cdetect. Unfortunately, none of them are listed as the smbus. When I try and probe each one of these devices for my tmp75 sensor chip, it doesn't find it. I also find it odd that when I connect a scope to the smb data and clock lines, I don't see any data communication during this probe process (I do see data when I use smb read/wite anywhere from windows).
I did check the log and there was initially an error with i2c-i801 where it stated "module verification failed: signature and/or required key missing - tainting kernel". I added #include <linux/init.h> and have not seen it again.
Thank you, guys.
Benjo

Not sure where you got your driver from then, because both the upstream
i2c-i801 driver and my standalone variant already include
<linux/init.h>.

Jean/Guenter,
I am not sure where I got the version from but it is working a little bit better after getting the one from your link. Thank you for noticing that difference. I now get the following using i2cdetect -l after loading i2c-dev and the newer i2c-i801.
I2c-0 i2c i915 gmbus ssc I2C adapter
I2c-1 i2c i915 gmbus vga I2C adapter
I2c-2 i2c i915 gmbus panel I2C adapter
I2c-3 i2c i915 gmbus dpc I2C adapter
I2c-4 i2c i915 gmbus dpb I2C adapter
I2c-5 i2c i915 gmbus dpd I2C adapter
I2c-6 i2c i915 gmbus DPDDC-D I2C adapter
Although I do see devices on i2c-1, I still do not see the smbus anywhere. This aligns with my not seeing any activity on the smbus with an oscilloscope during the i2cdetect process. What am I missing on why it is not communicating and/or finding my Lynx Point PCH as well as the devices connected to that smbus?
As always, thank you, everyone.
Benjo

Next step might be to run lspci -nn and compare the output with the PCI IDs
supported by your version of the i2c-i801 driver.

And again, check the kernel log after loading the i2c-i801 driver. If
probing the device fails for any reason, there should be an error
message in that log.

Yes. I have a system with LynxPoint. I tested it last night;
it fails to load on that system because of an ACPI conflict.

Guenter/Jean,
Does lm-sensors support the Intel Ibex Peak-M (QM57) Chip? I don't see it in the list. Thank you.

Looking it up on the web, its SMBus controller PCI ID is 0x3b30,
which is supported as "5/3400 Series (PCH)".
