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
Hans de Goede <>,
(Initial reverse engineering done by Olle Sandberg
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 <> the output of:
dmesg | grep abituguru
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 <> 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.

If you say yes here you get support for the Abit uGuru chips
sensor part. The voltage and frequency control parts of the Abit
uGuru are not supported. The Abit uGuru chip can be found on Abit
uGuru featuring motherboards (most modern Abit motherboards).
This driver can also be built as a module. If so, the module
will be called abituguru.
