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

| 30 | Module Parameters | |
| 31 | ----------------- | |
| 32 | ||
| 33 | * force: bool Force detection. Note this parameter only causes the | |
| 34 | detection to be skipped, and thus the insmod to | |
| 35 | succeed. If the uGuru can't be read the actual hwmon | |
| 36 | driver will not load and thus no hwmon device will get | |
| 37 | registered. | |
| 38 | * verbose: bool Should the driver be verbose? | |
| 39 | 0/off/false normal output | |
| 40 | 1/on/true + verbose error reporting (default) | |
| 41 | Default: 1 (the driver is still in the testing phase) | |
| 42 | ||
| 43 | Description | |
| 44 | ----------- | |
| 45 | ||
| 46 | This driver supports the hardware monitoring features of the third revision of | |
| 47 | the Abit uGuru chip, found on recent Abit uGuru featuring motherboards. | |
| 48 | ||
| 49 | The 3rd revision of the uGuru chip in reality is a Winbond W83L951G. | |
| 25985edc | 50 | Unfortunately this doesn't help since the W83L951G is a generic microcontroller |
| 3faa1ffb HG |
51 | with a custom Abit application running on it. |
| 52 | ||
| 53 | Despite Abit not releasing any information regarding the uGuru revision 3, | |
| 54 | Louis Kruger has managed to reverse engineer the sensor part of the uGuru. | |
| 55 | Without his work this driver would not have been possible. | |
| 56 | ||
| 57 | Known Issues | |
| 58 | ------------ | |
| 59 | ||
| 60 | The voltage and frequency control parts of the Abit uGuru are not supported, | |
| 61 | neither is writing any of the sensor settings and writing / reading the | |
| 62 | fanspeed control registers (FanEQ) | |

| 65 | include the output of: "dmesg | grep abituguru" |
