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.
58 
59 config DRM_I915_FORCE_PROBE
60 	string "Force probe i915 for selected Intel hardware IDs"
61 	depends on DRM_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.

89 config DRM_I915_CAPTURE_ERROR

92 	default y
93 	help
94 	  This option enables capturing the GPU state when a hang is detected.
95 	  This information is vital for triaging hangs and assists in debugging.
96 	  Please report any hang for triaging according to:
97 	    https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs
98 
99 	  If in doubt, say "Y".

105 	default y
106 	help
107 	  This option selects ZLIB_DEFLATE if it isn't already
108 	  selected and causes any error state captured upon a GPU hang
109 	  to be compressed using zlib.
110 
111 	  If in doubt, say "Y".

137 	  virtualization technology host support with integrated graphics.
138 	  With GVT-g, it's possible to have one integrated graphics
139 	  device shared by multiple VMs under KVM.
140 
141 	  Note that this driver only supports newer device from Broadwell on.
