   1Kernel driver abituguru3
   2========================
   3
   4Supported chips:
   5  * Abit uGuru revision 3 (Hardware Monitor part, reading only)
   6
   7    Prefix: 'abituguru3'
   8
   9    Addresses scanned: ISA 0x0E0
  10
  11    Datasheet: Not available, this driver is based on reverse engineering.
  12
  13    Note:
  14        The uGuru is a microcontroller with onboard firmware which programs
  15        it to behave as a hwmon IC. There are many different revisions of the
  16        firmware and thus effectively many different revisions of the uGuru.
  17        Below is an incomplete list with which revisions are used for which
  18        Motherboards:
  19
  20        - uGuru 1.00    ~ 1.24    (AI7, KV8-MAX3, AN7)
  21        - uGuru 2.0.0.0 ~ 2.0.4.2 (KV8-PRO)
  22        - uGuru 2.1.0.0 ~ 2.1.2.8 (AS8, AV8, AA8, AG8, AA8XE, AX8)
  23        - uGuru 2.3.0.0 ~ 2.3.0.9 (AN8)
  24        - uGuru 3.0.0.0 ~ 3.0.x.x (AW8, AL8, AT8, NI8 SLI, AT8 32X, AN8 32X,
  25          AW9D-MAX)
  26
  27        The abituguru3 driver is only for revision 3.0.x.x motherboards,
  28        this driver will not work on older motherboards. For older
  29        motherboards use the abituguru (without the 3 !) driver.

  36Module Parameters
  37-----------------
  38
  39* force: bool
  40                        Force detection. Note this parameter only causes the
  41                        detection to be skipped, and thus the insmod to
  42                        succeed. If the uGuru can't be read the actual hwmon
  43                        driver will not load and thus no hwmon device will get
  44                        registered.
  45* verbose: bool
  46                        Should the driver be verbose?
  47
  48                        * 0/off/false  normal output
  49                        * 1/on/true    + verbose error reporting (default)
  50
  51                        Default: 1 (the driver is still in the testing phase)

  53Description
  54-----------
  55
  56This driver supports the hardware monitoring features of the third revision of
  57the Abit uGuru chip, found on recent Abit uGuru featuring motherboards.
  58
  59The 3rd revision of the uGuru chip in reality is a Winbond W83L951G.
  60Unfortunately this doesn't help since the W83L951G is a generic microcontroller
  61with a custom Abit application running on it.
  62
  63Despite Abit not releasing any information regarding the uGuru revision 3,
  64Louis Kruger has managed to reverse engineer the sensor part of the uGuru.
  65Without his work this driver would not have been possible.
  66
  67Known Issues
  68------------
  69
  70The voltage and frequency control parts of the Abit uGuru are not supported,
  71neither is writing any of the sensor settings and writing / reading the
  72fanspeed control registers (FanEQ)
