abituguru3
Kernel driver abituguru3
========================
Supported chips:
* Abit uGuru revision 3 (Hardware Monitor part, reading only)
Prefix: 'abituguru3'
Addresses scanned: ISA 0x0E0
Datasheet: Not available, this driver is based on reverse engineering.
Note:
The uGuru is a microcontroller with onboard firmware which programs
it to behave as a hwmon IC. There are many different revisions of the
firmware and thus effectivly many different revisions of the uGuru.
Below is an incomplete list with which revisions are used for which
Motherboards:
uGuru 1.00 ~ 1.24 (AI7, KV8-MAX3, AN7)
uGuru 2.0.0.0 ~ 2.0.4.2 (KV8-PRO)
uGuru 2.1.0.0 ~ 2.1.2.8 (AS8, AV8, AA8, AG8, AA8XE, AX8)
uGuru 2.3.0.0 ~ 2.3.0.9 (AN8)
uGuru 3.0.0.0 ~ 3.0.x.x (AW8, AL8, AT8, NI8 SLI, AT8 32X, AN8 32X,
AW9D-MAX)
The abituguru3 driver is only for revison 3.0.x.x motherboards,
this driver will not work on older motherboards. For older
motherboards use the abituguru (without the 3 !) driver.

(Initial reverse engineering done by Louis Kruger)
Module Parameters
-----------------
* force: bool Force detection. Note this parameter only causes the
detection to be skipped, and thus the insmod to
succeed. If the uGuru can't be read the actual hwmon
driver will not load and thus no hwmon device will get
registered.
* verbose: bool Should the driver be verbose?
0/off/false normal output
1/on/true + verbose error reporting (default)
Default: 1 (the driver is still in the testing phase)
Description
-----------
This driver supports the hardware monitoring features of the third revision of
the Abit uGuru chip, found on recent Abit uGuru featuring motherboards.
The 3rd revision of the uGuru chip in reality is a Winbond W83L951G.
Unfortunatly this doesn't help since the W83L951G is a generic microcontroller
with a custom Abit application running on it.
Despite Abit not releasing any information regarding the uGuru revision 3,
Louis Kruger has managed to reverse engineer the sensor part of the uGuru.
Without his work this driver would not have been possible.
Known Issues
------------
The voltage and frequency control parts of the Abit uGuru are not supported,
neither is writing any of the sensor settings and writing / reading the
fanspeed control registers (FanEQ)
