  43           Choose this option if you have a system that has "Intel Graphics
  44           Media Accelerator" or "HD Graphics" integrated graphics,
  45           including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
  46           G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
  47           Core i5, Core i7 as well as Atom CPUs with integrated graphics.
  48
  49           This driver is used by the Intel driver in X.org 6.8 and
  50           XFree86 4.4 and above. It replaces the older i830 module that
  51           supported a subset of the hardware in older X.org releases.
  52
  53           Note that the older i810/i815 chipsets require the use of the
  54           i810 driver instead, and the Atom z5xx series has an entirely
  55           different implementation.
  56
  57           If "M" is selected, the module will be called i915.

  62         help
  63           This is the default value for the i915.force_probe module
  64           parameter. Using the module parameter overrides this option.
  65
  66           Force probe the i915 driver for Intel graphics devices that are
  67           recognized but not properly supported by this kernel version. Force
  68           probing an unsupported device taints the kernel. It is recommended to
  69           upgrade to a kernel version with proper support as soon as it is
  70           available.
  71
  72           It can also be used to block the probe of recognized and fully
  73           supported devices.
  74
  75           Use "" to disable force probe. If in doubt, use this.
  76
  77           Use "<pci-id>[,<pci-id>,...]" to force probe the i915 for listed
  78           devices. For example, "4500" or "4500,4571".
  79
  80           Use "*" to force probe the driver for all known devices. Not
  81           recommended.
  82
  83           Use "!" right before the ID to block the probe of the device. For
  84           example, "4500,!4571" forces the probe of 4500 and blocks the probe of
  85           4571.
  86
  87           Use "!*" to block the probe of the driver for all known devices.
