1 | Kernel driver abituguru3 |
| 2 | ======================== | |
| 3 | ||
| 4 | Supported chips: | |
| 5 | * Abit uGuru revision 3 (Hardware Monitor part, reading only) | |
| b04f2f7d | 6 | |
| 3faa1ffb | 7 | Prefix: 'abituguru3' |
| b04f2f7d | 8 | |
| 3faa1ffb | 9 | Addresses scanned: ISA 0x0E0 |
| b04f2f7d | 10 | |
| 3faa1ffb | 11 | Datasheet: Not available, this driver is based on reverse engineering. |
| b04f2f7d | 12 | |
| 3faa1ffb HG |
13 | Note: |
| 14 | The uGuru is a microcontroller with onboard firmware which programs | |
| 15 | it to behave as a hwmon IC. There are many different revisions of the | |
| 4776b9e3 | 16 | firmware and thus effectively many different revisions of the uGuru. |
| 3faa1ffb HG |
17 | Below is an incomplete list with which revisions are used for which |
| 18 | Motherboards: | |
| b04f2f7d MCC |
19 | |
| 20 | - uGuru 1.00 ~ 1.24 (AI7, KV8-MAX3, AN7) | |
| 21 | - uGuru 2.0.0.0 ~ 2.0.4.2 (KV8-PRO) | |
| 22 | - uGuru 2.1.0.0 ~ 2.1.2.8 (AS8, AV8, AA8, AG8, AA8XE, AX8) | |
| 23 | - uGuru 2.3.0.0 ~ 2.3.0.9 (AN8) | |
| 24 | - uGuru 3.0.0.0 ~ 3.0.x.x (AW8, AL8, AT8, NI8 SLI, AT8 32X, AN8 32X, | |
| 25 | AW9D-MAX) | |
| 26 | ||
| 4776b9e3 | 27 | The abituguru3 driver is only for revision 3.0.x.x motherboards, |
| 3faa1ffb HG |
28 | this driver will not work on older motherboards. For older |
| 29 | motherboards use the abituguru (without the 3 !) driver. | |

| 36 | Module Parameters | |
| 37 | ----------------- | |
| 38 | ||
| b04f2f7d MCC |
39 | * force: bool |
| 40 | Force detection. Note this parameter only causes the | |
| 3faa1ffb HG |
41 | detection to be skipped, and thus the insmod to |
| 42 | succeed. If the uGuru can't be read the actual hwmon | |
| 43 | driver will not load and thus no hwmon device will get | |
| 44 | registered. | |
| b04f2f7d MCC |
45 | * verbose: bool |
| 46 | Should the driver be verbose? | |
| 47 | ||
| 48 | * 0/off/false normal output | |
| 49 | * 1/on/true + verbose error reporting (default) | |
| 50 | ||
| 3faa1ffb HG |
51 | Default: 1 (the driver is still in the testing phase) |
| 52 | ||
| 53 | Description | |
| 54 | ----------- | |
| 55 | ||
| 56 | This driver supports the hardware monitoring features of the third revision of | |
| 57 | the Abit uGuru chip, found on recent Abit uGuru featuring motherboards. | |
| 58 | ||
| 59 | The 3rd revision of the uGuru chip in reality is a Winbond W83L951G. | |
| 25985edc | 60 | Unfortunately this doesn't help since the W83L951G is a generic microcontroller |
| 3faa1ffb HG |
61 | with a custom Abit application running on it. |
| 62 | ||
| 63 | Despite Abit not releasing any information regarding the uGuru revision 3, | |
| 64 | Louis Kruger has managed to reverse engineer the sensor part of the uGuru. | |
| 65 | Without his work this driver would not have been possible. | |
| 66 | ||
| 67 | Known Issues | |
| 68 | ------------ | |
| 69 | ||
| 70 | The voltage and frequency control parts of the Abit uGuru are not supported, | |
| 71 | neither is writing any of the sensor settings and writing / reading the | |
| 72 | fanspeed control registers (FanEQ) | |

| b04f2f7d | 75 | include the output of: `dmesg | grep abituguru` |
