1 Kernel driver abituguru
2 =======================
5 * Abit uGuru revision 1-3 (Hardware Monitor part only)
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
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
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

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)
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):
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)
64 Notice if you need any of the first three options above please insmod the
65 driver with verbose set to 3 and mail me <j.w.r.degoede@hhs.nl> the output of:
66 dmesg | grep abituguru
72 This driver supports the hardware monitoring features of the Abit uGuru chip
73 found on Abit uGuru featuring motherboards (most modern Abit motherboards).
75 The uGuru chip in reality is a Winbond W83L950D in disguise (despite Abit
76 claiming it is "a new microprocessor designed by the ABIT Engineers").
77 Unfortunatly this doesn't help since the W83L950D is a generic
78 microcontroller with a custom Abit application running on it.
80 Despite Abit not releasing any information regarding the uGuru, Olle
81 Sandberg <ollebull@gmail.com> has managed to reverse engineer the sensor part
82 of the uGuru. Without his work this driver would not have been possible.
87 The voltage and frequency control parts of the Abit uGuru are not supported.
