22 Choose this option if you have a system that has "Intel Graphics
23 Media Accelerator" or "HD Graphics" integrated graphics,
24 including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
25 G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
26 Core i5, Core i7 as well as Atom CPUs with integrated graphics.
27 If M is selected, the module will be called i915. AGP support
28 is required for this driver to work. This driver is used by
29 the Intel driver in X.org 6.8 and XFree86 4.4 and above. It
30 replaces the older i830 module that supported a subset of the
31 hardware in older X.org releases.
32
33 Note that the older i810/i815 chipsets require the use of the
34 i810 driver instead, and the Atom z5xx series has an entirely
35 different implementation.

43 i915 driver to support it by default. You can enable such support at
44 runtime with the module option i915.preliminary_hw_support=1; this
45 option changes the default for that module option.

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.
