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. |
