1 Kernel driver abituguru3 2 ======================== 3 4 Supported chips: 5 * Abit uGuru revision 3 (Hardware Monitor part, reading only) 6 7 Prefix: 'abituguru3' 8 9 Addresses scanned: ISA 0x0E0 10 11 Datasheet: Not available, this driver is based on reverse engineering. 12 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 16 firmware and thus effectively many different revisions of the uGuru. 17 Below is an incomplete list with which revisions are used for which 18 Motherboards: 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 27 The abituguru3 driver is only for revision 3.0.x.x motherboards, 28 this driver will not work on older motherboards. For older 29 motherboards use the abituguru (without the 3 !) driver. 30 31 Authors: 32 - Hans de Goede <j.w.r.degoede@hhs.nl>, 33 - (Initial reverse engineering done by Louis Kruger) 34 35 36 Module Parameters 37 ----------------- 38 39 * force: bool 40 Force detection. Note this parameter only causes the 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. 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 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. 60 Unfortunately this doesn't help since the W83L951G is a generic microcontroller 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) 73 74 If you encounter any problems please mail me <j.w.r.degoede@hhs.nl> and 75 include the output of: `dmesg | grep abituguru`
