   1 Kernel driver abituguru3
   2 ========================
   3
   4 Supported 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.

  36 Module 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)
  52
  53 Description
  54 -----------
  55
  56 This driver supports the hardware monitoring features of the third revision of
  57 the Abit uGuru chip, found on recent Abit uGuru featuring motherboards.
  58
  59 The 3rd revision of the uGuru chip in reality is a Winbond W83L951G.
  60 Unfortunately this doesn't help since the W83L951G is a generic microcontroller
  61 with a custom Abit application running on it.
  62
  63 Despite Abit not releasing any information regarding the uGuru revision 3,
  64 Louis Kruger has managed to reverse engineer the sensor part of the uGuru.
  65 Without his work this driver would not have been possible.
  66
  67 Known Issues
  68 ------------
  69
  70 The voltage and frequency control parts of the Abit uGuru are not supported,
  71 neither is writing any of the sensor settings and writing / reading the
  72 fanspeed control registers (FanEQ)
