1 | Kernel driver abituguru |
2 | ======================= | |
3 | ||
4 | Supported chips: | |
3faa1ffb | 5 | * Abit uGuru revision 1 & 2 (Hardware Monitor part only) |
f2b84bbc HG |
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) | |
3faa1ffb HG |
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 seperate 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 | |
3faa1ffb HG |
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. | |
5cab828b HG |
51 | * bank1_types: int[] Bank1 sensortype autodetection override: |
52 | -1 autodetect (default) | |
53 | 0 volt sensor | |
54 | 1 temp sensor | |
55 | 2 not connected | |
f2b84bbc HG |
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 | |
5cab828b | 63 | 2 + sensors type probing info (default) |
f2b84bbc HG |
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 | |

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). | |

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"). Unfortunatly this doesn't help since the | |
82 | W83L950D is a generic microcontroller with a custom Abit application running | |
83 | on it. | |

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. | |

92 | The voltage and frequency control parts of the Abit uGuru are not supported. |
