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 effectively 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 revision 3.0.x.x motherboards,
|
|
this driver will not work on older motherboards. For older
|
|
motherboards use the abituguru (without the 3 !) driver.

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.
|
|
Unfortunately 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)
|
|

|
|
include the output of: `dmesg | grep abituguru`
