Description
|
|
-----------
|
|
|
|
This driver implements support for the Nuvoton NCT6683D eSIO chip.
|
|
|
|
The chips implement up to shared 32 temperature and voltage sensors.
|
|
It supports up to 16 fan rotation sensors and up to 8 fan control engines.
|
|
|
|
Temperatures are measured in degrees Celsius. Measurement resolution is
|
|
0.5 degrees C.
|
|
|
|
Voltage sensors (also known as IN sensors) report their values in millivolts.
|
|
|
|
Fan rotation speeds are reported in RPM (rotations per minute).
|
|
|
|
Usage Note
|
|
----------
|
|
|
|
Limit register locations on Intel boards with EC firmware version 1.0
|
|
build date 04/03/13 do not match the register locations in the Nuvoton
|
|
datasheet. Nuvoton confirms that Intel uses a special firmware version
|
|
with different register addresses. The specification describing the Intel
|
|
firmware is held under NDA by Nuvoton and Intel and not available
|
|
to the public.
|
|
|
|
Some of the register locations can be reverse engineered; others are too
|
|
well hidden. Given this, writing any values from the operating system is
|
|
considered too risky with this firmware and has been disabled. All limits
|
|
must all be written from the BIOS.
|
|
|
|
The driver has only been tested with the Intel firmware, and by default
|
|
only instantiates on Intel boards. To enable it on non-Intel boards,
|
|
set the 'force' module parameter to 1.
