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

| Module Parameters | |
| ----------------- | |
| * force: bool Force detection. Note this parameter only causes the | |
| detection to be skipped, and thus the insmod to | |
| succeed. If the uGuru can't be read the actual hwmon | |
| driver will not load and thus no hwmon device will get | |
| registered. | |
| * verbose: bool Should the driver be verbose? | |
| 0/off/false normal output | |
| 1/on/true + verbose error reporting (default) | |
| Default: 1 (the driver is still in the testing phase) | |
| Description | |
| ----------- | |
| This driver supports the hardware monitoring features of the third revision of | |
| the Abit uGuru chip, found on recent Abit uGuru featuring motherboards. | |
| The 3rd revision of the uGuru chip in reality is a Winbond W83L951G. | |
| Unfortunately this doesn't help since the W83L951G is a generic microcontroller | |
| with a custom Abit application running on it. | |
| Despite Abit not releasing any information regarding the uGuru revision 3, | |
| Louis Kruger has managed to reverse engineer the sensor part of the uGuru. | |
| Without his work this driver would not have been possible. | |
| Known Issues | |
| ------------ | |
| The voltage and frequency control parts of the Abit uGuru are not supported, | |
| neither is writing any of the sensor settings and writing / reading the | |
| fanspeed control registers (FanEQ) | |
| If you encounter any problems please mail me <j.w.r.degoede@hhs.nl> and | |
| include the output of: "dmesg | grep abituguru" |
