1Kernel driver abituguru
2=======================
3
4Supported chips:
5 * Abit uGuru (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.

19Module Parameters
20-----------------
21
22* force: bool Force detection. Note this parameter only causes the
23 detection to be skipped, if the uGuru can't be read
24 the module initialization (insmod) will still fail.
25* fan_sensors: int Tell the driver how many fan speed sensors there are
26 on your motherboard. Default: 0 (autodetect).
27* pwms: int Tell the driver how many fan speed controls (fan
28 pwms) your motherboard has. Default: 0 (autodetect).
29* verbose: int How verbose should the driver be? (0-3):
30 0 normal output
31 1 + verbose error reporting
32 2 + sensors type probing info\n"
33 3 + retryable error reporting
34 Default: 2 (the driver is still in the testing phase)
35
36Notice if you need any of the first three options above please insmod the
37driver with verbose set to 3 and mail me <j.w.r.degoede@hhs.nl> the output of:
38dmesg | grep abituguru

41Description
42-----------
43
44This driver supports the hardware monitoring features of the Abit uGuru chip
45found on Abit uGuru featuring motherboards (most modern Abit motherboards).
46
47The uGuru chip in reality is a Winbond W83L950D in disguise (despite Abit
48claiming it is "a new microprocessor designed by the ABIT Engineers").
49Unfortunatly this doesn't help since the W83L950D is a generic
50microcontroller with a custom Abit application running on it.
51
52Despite Abit not releasing any information regarding the uGuru, Olle
53Sandberg <ollebull@gmail.com> has managed to reverse engineer the sensor part
54of the uGuru. Without his work this driver would not have been possible.

56Known Issues
57------------
58
59The voltage and frequency control parts of the Abit uGuru are not supported.
