If a temperature sensor is configured for thermistors, the attribute values
are ignored. If the thermal sensor type is Intel PECI, the temperature offset
must be programmed to the critical CPU temperature.
Preliminary support
-------------------
Support for IT8607E, IT8665E, and IT8686E is preliminary. Voltage readings,
temperature readings, fan control, and fan speed measurements may be wrong
and/or missing. Fan control and fan speed may be enabled and reported for
non-existing fans. Please report any problems and inconsistencies.
Reporting information for unsupported chips
-------------------------------------------
If the chip in your system is not yet supported by the driver, please provide
the following information.
First, run sensors-detect. It will tell you something like
Probing for Super-I/O at 0x2e/0x2f
...
Trying family `ITE'... Yes
Found unknown chip with ID 0x8665
(logical device 4 has address 0x290, could be sensors)
With this information, run the following commands.
sudo isadump -k 0x87,0x01,0x55,0x55 0x2e 0x2f 7
sudo isadump 0x295 0x296
and report the results.
The addresses in the first command are from "Probing for Super-I/O at
0x2e/0x2f". Use those addresses in the first command.
sudo isadump -k 0x87,0x01,0x55,0x55 0x2e 0x2f 7
The addresses in the second command are from "has address 0x290".
Add 5 and 6 to this address for the next command.
sudo isadump 0x295 0x296
Next, force-install the driver by providing one of the already supported chips
as forced ID. Useful IDs to test are 0x8622, 0x8628, 0x8728, and 0x8732, though
feel free to test more IDs. For each ID, instantiate the driver as follows
(this example is instantiating driver with ID 0x8622).
sudo modprobe it87 force_id=0x8622
After entering this command, run the "sensors" command and provide the output.
Then unload the driver with
sudo modprobe -r it87
Repeat with different chip IDs, and report each result.
Please also report your board type as well as voltages and fan settings from
the BIOS. If possible, connect fans to different fan headers and let us know
if all fans are detected and reported.
This information _might_ give us enough information to add experimental support
for the chip in question. No guarantees, though - unless a datasheet is
available, something is likely to be wrong.
