1Kernel driver abituguru 2======================= 3 4Supported chips: 5 6 * Abit uGuru revision 1 & 2 (Hardware Monitor part only) 7 8 Prefix: 'abituguru' 9 10 Addresses scanned: ISA 0x0E0 11 12 Datasheet: Not available, this driver is based on reverse engineering. 13 A "Datasheet" has been written based on the reverse engineering it 14 should be available in the same dir as this file under the name 15 abituguru-datasheet. 16 17 Note: 18 The uGuru is a microcontroller with onboard firmware which programs 19 it to behave as a hwmon IC. There are many different revisions of the 20 firmware and thus effectively many different revisions of the uGuru. 21 Below is an incomplete list with which revisions are used for which 22 Motherboards: 23 24 - uGuru 1.00 ~ 1.24 (AI7, KV8-MAX3, AN7) [1]_ 25 - uGuru 2.0.0.0 ~ 2.0.4.2 (KV8-PRO) 26 - uGuru 2.1.0.0 ~ 2.1.2.8 (AS8, AV8, AA8, AG8, AA8XE, AX8) 27 - uGuru 2.2.0.0 ~ 2.2.0.6 (AA8 Fatal1ty) 28 - uGuru 2.3.0.0 ~ 2.3.0.9 (AN8) 29 - uGuru 3.0.0.0 ~ 3.0.x.x (AW8, AL8, AT8, NI8 SLI, AT8 32X, AN8 32X, 30 AW9D-MAX) [2]_ 31 32.. [1] For revisions 2 and 3 uGuru's the driver can autodetect the 33 sensortype (Volt or Temp) for bank1 sensors, for revision 1 uGuru's 34 this does not always work. For these uGuru's the autodetection can 35 be overridden with the bank1_types module param. For all 3 known 36 revision 1 motherboards the correct use of this param is: 37 bank1_types=1,1,0,0,0,0,0,2,0,0,0,0,2,0,0,1 38 You may also need to specify the fan_sensors option for these boards 39 fan_sensors=5 40 41.. [2] There is a separate abituguru3 driver for these motherboards, 42 the abituguru (without the 3 !) driver will not work on these 43 motherboards (and visa versa)! 44 45Authors: 46 - Hans de Goede <j.w.r.degoede@hhs.nl>, 47 - (Initial reverse engineering done by Olle Sandberg 48 <ollebull@gmail.com>) 49 50 51Module Parameters 52----------------- 53 54* force: bool 55 Force detection. Note this parameter only causes the 56 detection to be skipped, and thus the insmod to 57 succeed. If the uGuru can't be read the actual hwmon 58 driver will not load and thus no hwmon device will get 59 registered. 60* bank1_types: int[] 61 Bank1 sensortype autodetection override: 62 63 * -1 autodetect (default) 64 * 0 volt sensor 65 * 1 temp sensor 66 * 2 not connected 67* fan_sensors: int 68 Tell the driver how many fan speed sensors there are 69 on your motherboard. Default: 0 (autodetect). 70* pwms: int 71 Tell the driver how many fan speed controls (fan 72 pwms) your motherboard has. Default: 0 (autodetect). 73* verbose: int 74 How verbose should the driver be? (0-3): 75 76 * 0 normal output 77 * 1 + verbose error reporting 78 * 2 + sensors type probing info (default) 79 * 3 + retryable error reporting 80 81 Default: 2 (the driver is still in the testing phase) 82 83Notice: if you need any of the first three options above please insmod the 84driver with verbose set to 3 and mail me <j.w.r.degoede@hhs.nl> the output of: 85dmesg | grep abituguru 86 87 88Description 89----------- 90 91This driver supports the hardware monitoring features of the first and 92second revision of the Abit uGuru chip found on Abit uGuru featuring 93motherboards (most modern Abit motherboards). 94 95The first and second revision of the uGuru chip in reality is a Winbond 96W83L950D in disguise (despite Abit claiming it is "a new microprocessor 97designed by the ABIT Engineers"). Unfortunately this doesn't help since the 98W83L950D is a generic microcontroller with a custom Abit application running 99on it. 100 101Despite Abit not releasing any information regarding the uGuru, Olle 102Sandberg <ollebull@gmail.com> has managed to reverse engineer the sensor part 103of the uGuru. Without his work this driver would not have been possible. 104 105Known Issues 106------------ 107 108The voltage and frequency control parts of the Abit uGuru are not supported. 109 110.. toctree:: 111 :maxdepth: 1 112 113 abituguru-datasheet.rst
