Kernel driver abituguru
|
|
=======================
|
|
|
|
Supported chips:
|
|
* Abit uGuru (Hardware Monitor part only)
|
|
Prefix: 'abituguru'
|
|
Addresses scanned: ISA 0x0E0
|
|
Datasheet: Not available, this driver is based on reverse engineering.
|
|
A "Datasheet" has been written based on the reverse engineering it
|
|
should be available in the same dir as this file under the name
|
|
abituguru-datasheet.

Module Parameters
|
|
-----------------
|
|
|
|
* force: bool Force detection. Note this parameter only causes the
|
|
detection to be skipped, if the uGuru can't be read
|
|
the module initialization (insmod) will still fail.
|
|
* fan_sensors: int Tell the driver how many fan speed sensors there are
|
|
on your motherboard. Default: 0 (autodetect).
|
|
* pwms: int Tell the driver how many fan speed controls (fan
|
|
pwms) your motherboard has. Default: 0 (autodetect).
|
|
* verbose: int How verbose should the driver be? (0-3):
|
|
0 normal output
|
|
1 + verbose error reporting
|
|
2 + sensors type probing info\n"
|
|
3 + retryable error reporting
|
|
Default: 2 (the driver is still in the testing phase)
|
|
|
|
Notice if you need any of the first three options above please insmod the
|
|
driver with verbose set to 3 and mail me <j.w.r.degoede@hhs.nl> the output of:
|
|
dmesg | grep abituguru

Description
|
|
-----------
|
|
|
|
This driver supports the hardware monitoring features of the Abit uGuru chip
|
|
found on Abit uGuru featuring motherboards (most modern Abit motherboards).
|
|
|
|
The uGuru chip in reality is a Winbond W83L950D in disguise (despite Abit
|
|
claiming it is "a new microprocessor designed by the ABIT Engineers").
|
|
Unfortunatly this doesn't help since the W83L950D is a generic
|
|
microcontroller with a custom Abit application running on it.
|
|
|
|
Despite Abit not releasing any information regarding the uGuru, Olle
|
|
Sandberg <ollebull@gmail.com> has managed to reverse engineer the sensor part
|
|
of the uGuru. Without his work this driver would not have been possible.
|
|
|
|
Known Issues
|
|
------------
|
|
|
|
The voltage and frequency control parts of the Abit uGuru are not supported.
