1 | Kernel driver abituguru |
2 | ======================= |
3 | |
4 | Supported chips: |
5 | * Abit uGuru revision 1 & 2 (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 | Note: |
13 | The uGuru is a microcontroller with onboard firmware which programs |
14 | it to behave as a hwmon IC. There are many different revisions of the |
15 | firmware and thus effectivly many different revisions of the uGuru. |
16 | Below is an incomplete list with which revisions are used for which |
17 | Motherboards: |
18 | uGuru 1.00 ~ 1.24 (AI7, KV8-MAX3, AN7) (1) |
19 | uGuru 2.0.0.0 ~ 2.0.4.2 (KV8-PRO) |
20 | uGuru 2.1.0.0 ~ 2.1.2.8 (AS8, AV8, AA8, AG8, AA8XE, AX8) |
21 | uGuru 2.2.0.0 ~ 2.2.0.6 (AA8 Fatal1ty) |
22 | uGuru 2.3.0.0 ~ 2.3.0.9 (AN8) |
23 | uGuru 3.0.0.0 ~ 3.0.x.x (AW8, AL8, AT8, NI8 SLI, AT8 32X, AN8 32X, |
24 | AW9D-MAX) (2) |
25 | 1) For revisions 2 and 3 uGuru's the driver can autodetect the |
26 | sensortype (Volt or Temp) for bank1 sensors, for revision 1 uGuru's |
27 | this doesnot always work. For these uGuru's the autodection can |
28 | be overriden with the bank1_types module param. For all 3 known |
29 | revison 1 motherboards the correct use of this param is: |
30 | bank1_types=1,1,0,0,0,0,0,2,0,0,0,0,2,0,0,1 |
31 | You may also need to specify the fan_sensors option for these boards |
32 | fan_sensors=5 |
33 | 2) There is a separate abituguru3 driver for these motherboards, |
34 | the abituguru (without the 3 !) driver will not work on these |
35 | motherboards (and visa versa)! |

43 | Module Parameters |
44 | ----------------- |
45 | |
46 | * force: bool Force detection. Note this parameter only causes the |
47 | detection to be skipped, and thus the insmod to |
48 | succeed. If the uGuru can't be read the actual hwmon |
49 | driver will not load and thus no hwmon device will get |
50 | registered. |
51 | * bank1_types: int[] Bank1 sensortype autodetection override: |
52 | -1 autodetect (default) |
53 | 0 volt sensor |
54 | 1 temp sensor |
55 | 2 not connected |
56 | * fan_sensors: int Tell the driver how many fan speed sensors there are |
57 | on your motherboard. Default: 0 (autodetect). |
58 | * pwms: int Tell the driver how many fan speed controls (fan |
59 | pwms) your motherboard has. Default: 0 (autodetect). |
60 | * verbose: int How verbose should the driver be? (0-3): |
61 | 0 normal output |
62 | 1 + verbose error reporting |
63 | 2 + sensors type probing info (default) |
64 | 3 + retryable error reporting |
65 | Default: 2 (the driver is still in the testing phase) |
66 | |
67 | Notice if you need any of the first three options above please insmod the |
68 | driver with verbose set to 3 and mail me <j.w.r.degoede@hhs.nl> the output of: |
69 | dmesg | grep abituguru |

72 | Description |
73 | ----------- |
74 | |
75 | This driver supports the hardware monitoring features of the first and |
76 | second revision of the Abit uGuru chip found on Abit uGuru featuring |
77 | motherboards (most modern Abit motherboards). |
78 | |
79 | The first and second revision of the uGuru chip in reality is a Winbond |
80 | W83L950D in disguise (despite Abit claiming it is "a new microprocessor |
81 | designed by the ABIT Engineers"). Unfortunately this doesn't help since the |
82 | W83L950D is a generic microcontroller with a custom Abit application running |
83 | on it. |
84 | |
85 | Despite Abit not releasing any information regarding the uGuru, Olle |
86 | Sandberg <ollebull@gmail.com> has managed to reverse engineer the sensor part |
87 | of the uGuru. Without his work this driver would not have been possible. |
88 | |
89 | Known Issues |
90 | ------------ |
91 | |
92 | The voltage and frequency control parts of the Abit uGuru are not supported. |
