Supported chips:

|
|
* Abit uGuru revision 3 (Hardware Monitor part, reading only)

|
|
Prefix: 'abituguru3'

Datasheet: Not available, this driver is based on reverse engineering.

|
|
Note:
|
| 10 |
|
|
The uGuru is a microcontroller with onboard firmware which programs
|
| 11 |
|
|
it to behave as a hwmon IC. There are many different revisions of the
|
| 12 |
|
|
firmware and thus effectivly many different revisions of the uGuru.
|
| 13 |
|
|
Below is an incomplete list with which revisions are used for which
|
| 14 |
|
|
Motherboards:
|
| 15 |
|
|
uGuru 1.00 ~ 1.24 (AI7, KV8-MAX3, AN7)
|
| 16 |
|
|
uGuru 2.0.0.0 ~ 2.0.4.2 (KV8-PRO)
|
| 17 |
|
|
uGuru 2.1.0.0 ~ 2.1.2.8 (AS8, AV8, AA8, AG8, AA8XE, AX8)
|
| 18 |
|
|
uGuru 2.3.0.0 ~ 2.3.0.9 (AN8)
|
| 19 |
|
|
uGuru 3.0.0.0 ~ 3.0.x.x (AW8, AL8, AT8, NI8 SLI, AT8 32X, AN8 32X,
|
| 20 |
|
|
AW9D-MAX)
|
| 21 |
|
|
The abituguru3 driver is only for revison 3.0.x.x motherboards,
|
| 22 |
|
|
this driver will not work on older motherboards. For older
|
| 23 |
|
|
motherboards use the abituguru (without the 3 !) driver.

Module Parameters
|
| 31 |
|
|
-----------------
|
| 32 |
|
|
|
| 33 |
|
|
* force: bool Force detection. Note this parameter only causes the
|
| 34 |
|
|
detection to be skipped, and thus the insmod to
|
| 35 |
|
|
succeed. If the uGuru can't be read the actual hwmon
|
| 36 |
|
|
driver will not load and thus no hwmon device will get
|
| 37 |
|
|
registered.
|
| 38 |
|
|
* verbose: bool Should the driver be verbose?
|
| 39 |
|
|
0/off/false normal output
|
| 40 |
|
|
1/on/true + verbose error reporting (default)
|
| 41 |
|
|
Default: 1 (the driver is still in the testing phase)

Description
|
| 44 |
|
|
-----------
|
| 45 |
|
|
|
| 46 |
|
|
This driver supports the hardware monitoring features of the third revision of
|
| 47 |
|
|
the Abit uGuru chip, found on recent Abit uGuru featuring motherboards.
|
| 48 |
|
|
|
| 49 |
|
|
The 3rd revision of the uGuru chip in reality is a Winbond W83L951G.
|
| 50 |
|
|
Unfortunatly this doesn't help since the W83L951G is a generic microcontroller
|
| 51 |
|
|
with a custom Abit application running on it.
|
| 52 |
|
|
|
| 53 |
|
|
Despite Abit not releasing any information regarding the uGuru revision 3,
|
| 54 |
|
|
Louis Kruger has managed to reverse engineer the sensor part of the uGuru.
|
| 55 |
|
|
Without his work this driver would not have been possible.

Known Issues
|
| 58 |
|
|
------------
|
| 59 |
|
|
|
| 60 |
|
|
The voltage and frequency control parts of the Abit uGuru are not supported,
|
| 61 |
|
|
neither is writing any of the sensor settings and writing / reading the
|
| 62 |
|
|
fanspeed control registers (FanEQ)
