1 | Kernel driver abituguru | ||
2 | ======================= | ||
3 | |||
4 | Supported chips: | ||
5 | * Abit uGuru (Hardware Monitor part only) | ||
6 | Prefix: 'abituguru' | ||
7 | Addresses scanned: ISA 0x0E0 | ||
8 | Datasheet: Not available, this driver is based on reverse engineering. | ||
9 | A "Datasheet" has been written based on the reverse engineering it | ||
10 | should be available in the same dir as this file under the name | ||
11 | abituguru-datasheet. | ||
12 | |||
13 | Authors: | ||
14 | Hans de Goede <j.w.r.degoede@hhs.nl>, | ||
15 | (Initial reverse engineering done by Olle Sandberg | ||
16 | <ollebull@gmail.com>) | ||

18 | |||
19 | Module Parameters | ||
20 | ----------------- | ||
21 | |||
22 | * force: bool Force detection. Note this parameter only causes the | ||
23 | detection to be skipped, if the uGuru can't be read | ||
24 | the module initialization (insmod) will still fail. | ||
25 | * fan_sensors: int Tell the driver how many fan speed sensors there are | ||
26 | on your motherboard. Default: 0 (autodetect). | ||
27 | * pwms: int Tell the driver how many fan speed controls (fan | ||
28 | pwms) your motherboard has. Default: 0 (autodetect). | ||
29 | * verbose: int How verbose should the driver be? (0-3): | ||
30 | 0 normal output | ||
31 | 1 + verbose error reporting | ||
32 | 2 + sensors type probing info\n" | ||
33 | 3 + retryable error reporting | ||
34 | Default: 2 (the driver is still in the testing phase) | ||
35 | |||
36 | Notice if you need any of the first three options above please insmod the | ||
37 | driver with verbose set to 3 and mail me <j.w.r.degoede@hhs.nl> the output of: | ||
38 | dmesg | grep abituguru | ||

41 | Description | ||
42 | ----------- | ||
43 | |||
44 | This driver supports the hardware monitoring features of the Abit uGuru chip | ||
45 | found on Abit uGuru featuring motherboards (most modern Abit motherboards). | ||
46 | |||
47 | The uGuru chip in reality is a Winbond W83L950D in disguise (despite Abit | ||
48 | claiming it is "a new microprocessor designed by the ABIT Engineers"). | ||
49 | Unfortunatly this doesn't help since the W83L950D is a generic | ||
50 | microcontroller with a custom Abit application running on it. | ||
51 | |||
52 | Despite Abit not releasing any information regarding the uGuru, Olle | ||
53 | Sandberg <ollebull@gmail.com> has managed to reverse engineer the sensor part | ||
54 | of the uGuru. Without his work this driver would not have been possible. | ||
55 | |||
56 | Known Issues | ||
57 | ------------ | ||
58 | |||
59 | The voltage and frequency control parts of the Abit uGuru are not supported. | ||
