I am trying to find a way to access and/or control fan speed via Linux on an Intel Q45 chipset. This chipset contains a feature called Intel Quiet System Technology (Intel QST), which is a part of the Intel Management Engine (Intel ME) running on an embedded co-processor. Intel describes QST as follows:

The Intel Management Engine (ME) hosts a firmware subsystem – Intel
Quiet System Technology (QST) – that provides support for the
monitoring of temperature, voltage, current and fan speed sensors that
are provided within the Chipset, the Processor and other devices on
the Motherboard. For each sensor, a Health Status, based upon
established thresholds, will be determined at regular intervals. Intel
QST also provides support for acoustically-optimized fan speed
control. Based upon readings obtained from the temperature sensors,
Intel QST will determine, over time, the optimal speeds at which to
operate the available cooling fans, in order to address existing
thermal conditions with the lowest possible acoustic impact.

Someone implemented a Linux driver for Intel QST in December 2012. Unfortunately, all references seem to a point to a defunct git repository (http://mose.dyndns.org/mei.git). Other references indicate the successful use of the driver via lm_sensors.

I have spent some time looking through the Linux source but so far, I haven't found any trace of this driver.

• Was Intel QST support ever included in the Linux kernel?


• If so, which driver/kernel module(s) are required for Intel QST support?
