1 Kernel driver abituguru
2 =======================
6 * Abit uGuru revision 1 & 2 (Hardware Monitor part only)
10 Addresses scanned: ISA 0x0E0
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
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 effectivly many different revisions of the uGuru.
21 Below is an incomplete list with which revisions are used for which
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,
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 revison 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
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)!

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
61 Bank1 sensortype autodetection override:
63 * -1 autodetect (default)
68 Tell the driver how many fan speed sensors there are
69 on your motherboard. Default: 0 (autodetect).
71 Tell the driver how many fan speed controls (fan
72 pwms) your motherboard has. Default: 0 (autodetect).
74 How verbose should the driver be? (0-3):
77 * 1 + verbose error reporting
78 * 2 + sensors type probing info (default)
79 * 3 + retryable error reporting
81 Default: 2 (the driver is still in the testing phase)
83 Notice: if you need any of the first three options above please insmod the
84 driver with verbose set to 3 and mail me <j.w.r.degoede@hhs.nl> the output of:
85 dmesg | grep abituguru
91 This driver supports the hardware monitoring features of the first and
92 second revision of the Abit uGuru chip found on Abit uGuru featuring
93 motherboards (most modern Abit motherboards).
95 The first and second revision of the uGuru chip in reality is a Winbond
96 W83L950D in disguise (despite Abit claiming it is "a new microprocessor
97 designed by the ABIT Engineers"). Unfortunately this doesn't help since the
98 W83L950D is a generic microcontroller with a custom Abit application running
101 Despite Abit not releasing any information regarding the uGuru, Olle
102 Sandberg <ollebull@gmail.com> has managed to reverse engineer the sensor part
103 of the uGuru. Without his work this driver would not have been possible.
108 The voltage and frequency control parts of the Abit uGuru are not supported.
