1Kernel driver abituguru 2======================= 3 4Supported chips: 5 * Abit uGuru revision 1-3 (Hardware Monitor part only) 6 Prefix: 'abituguru' 7 Addresses scanned: ISA 0x0E0 8 Datasheet: Not available, this driver is based on reverse engineering. 9 A "Datasheet" has been written based on the reverse engineering it 10 should be available in the same dir as this file under the name 11 abituguru-datasheet. 12 Note: 13 The uGuru is a microcontroller with onboard firmware which programs 14 it to behave as a hwmon IC. There are many different revisions of the 15 firmware and thus effectivly many different revisions of the uGuru. 16 Below is an incomplete list with which revisions are used for which 17 Motherboards: 18 uGuru 1.00 ~ 1.24 (AI7, KV8-MAX3, AN7) (1) 19 uGuru 2.0.0.0 ~ 2.0.4.2 (KV8-PRO) 20 uGuru 2.1.0.0 ~ 2.1.2.8 (AS8, AV8, AA8, AG8, AA8XE, AX8) 21 uGuru 2.2.0.0 ~ 2.2.0.6 (AA8 Fatal1ty) 22 uGuru 2.3.0.0 ~ 2.3.0.9 (AN8) 23 uGuru 3.0.0.0 ~ 3.0.1.2 (AW8, AL8, NI8) 24 uGuru 4.xxxxx? (AT8 32X) (2) 25 1) For revisions 2 and 3 uGuru's the driver can autodetect the 26 sensortype (Volt or Temp) for bank1 sensors, for revision 1 uGuru's 27 this doesnot always work. For these uGuru's the autodection can 28 be overriden with the bank1_types module param. For all 3 known 29 revison 1 motherboards the correct use of this param is: 30 bank1_types=1,1,0,0,0,0,0,2,0,0,0,0,2,0,0,1 31 You may also need to specify the fan_sensors option for these boards 32 fan_sensors=5 33 2) The current version of the abituguru driver is known to NOT work 34 on these Motherboards 35 36Authors: 37 Hans de Goede <j.w.r.degoede@hhs.nl>, 38 (Initial reverse engineering done by Olle Sandberg 39 <ollebull@gmail.com>) 40 41 42Module Parameters 43----------------- 44 45* force: bool Force detection. Note this parameter only causes the 46 detection to be skipped, if the uGuru can't be read 47 the module initialization (insmod) will still fail. 48* bank1_types: int[] Bank1 sensortype autodetection override: 49 -1 autodetect (default) 50 0 volt sensor 51 1 temp sensor 52 2 not connected 53* fan_sensors: int Tell the driver how many fan speed sensors there are 54 on your motherboard. Default: 0 (autodetect). 55* pwms: int Tell the driver how many fan speed controls (fan 56 pwms) your motherboard has. Default: 0 (autodetect). 57* verbose: int How verbose should the driver be? (0-3): 58 0 normal output 59 1 + verbose error reporting 60 2 + sensors type probing info (default) 61 3 + retryable error reporting 62 Default: 2 (the driver is still in the testing phase) 63 64Notice if you need any of the first three options above please insmod the 65driver with verbose set to 3 and mail me <j.w.r.degoede@hhs.nl> the output of: 66dmesg | grep abituguru 67 68 69Description 70----------- 71 72This driver supports the hardware monitoring features of the Abit uGuru chip 73found on Abit uGuru featuring motherboards (most modern Abit motherboards). 74 75The uGuru chip in reality is a Winbond W83L950D in disguise (despite Abit 76claiming it is "a new microprocessor designed by the ABIT Engineers"). 77Unfortunatly this doesn't help since the W83L950D is a generic 78microcontroller with a custom Abit application running on it. 79 80Despite Abit not releasing any information regarding the uGuru, Olle 81Sandberg <ollebull@gmail.com> has managed to reverse engineer the sensor part 82of the uGuru. Without his work this driver would not have been possible. 83 84Known Issues 85------------ 86 87The voltage and frequency control parts of the Abit uGuru are not supported. 88
