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>) | |

| 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. |
