There are many different revisions of the + firmware and thus effectively 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 revision 3.0.x.x motherboards, + this driver will not work on older motherboards. For older + motherboards use the abituguru (without the 3 !) driver. + +Authors: + - Hans de Goede <j.w.r.degoede@hhs.nl>, + - (Initial reverse engineering done by Louis Kruger) + + +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` |
