  19. Module Parameters
    20. 

  20. -----------------
    21. 

  21. 

  22. * force: bool		Force detection. Note this parameter only causes the
    23. 

  23. 			detection to be skipped, if the uGuru can't be read
    24. 

  24. 			the module initialization (insmod) will still fail.
    25. 

  25. * fan_sensors: int	Tell the driver how many fan speed sensors there are
    26. 

  26. 			on your motherboard. Default: 0 (autodetect).
    27. 

  27. * pwms: int		Tell the driver how many fan speed controls (fan
    28. 

  28. 			pwms) your motherboard has. Default: 0 (autodetect).
    29. 

  29. * verbose: int		How verbose should the driver be? (0-3):
    30. 

  30. 			   0 normal output
    31. 

  31. 			   1 + verbose error reporting
    32. 

  32. 			   2 + sensors type probing info\n"
    33. 

  33. 			   3 + retryable error reporting
    34. 

  34. 			Default: 2 (the driver is still in the testing phase)
    35. 

  35. 

  36. Notice if you need any of the first three options above please insmod the
    37. 

  37. driver with verbose set to 3 and mail me <j.w.r.degoede@hhs.nl> the output of:
    38. 

  38. dmesg | grep abituguru
    39.

  41. Description
    42. 

  42. -----------
    43. 

  43. 

  44. This driver supports the hardware monitoring features of the Abit uGuru chip
    45. 

  45. found on Abit uGuru featuring motherboards (most modern Abit motherboards).
    46. 

  46. 

  47. The uGuru chip in reality is a Winbond W83L950D in disguise (despite Abit
    48. 

  48. claiming it is "a new microprocessor designed by the ABIT Engineers").
    49. 

  49. Unfortunatly this doesn't help since the W83L950D is a generic
    50. 

  50. microcontroller with a custom Abit application running on it.
    51. 

  51. 

  52. Despite Abit not releasing any information regarding the uGuru, Olle
    53. 

  53. Sandberg <ollebull@gmail.com> has managed to reverse engineer the sensor part
    54. 

  54. of the uGuru. Without his work this driver would not have been possible.
    55. 

  55. 

  56. Known Issues
    57. 

  57. ------------
    58. 

  58. 

  59. The voltage and frequency control parts of the Abit uGuru are not supported.
