42	  Choose this option if you have a system that has "Intel Graphics
43	  Media Accelerator" or "HD Graphics" integrated graphics,
44	  including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
45	  G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
46	  Core i5, Core i7 as well as Atom CPUs with integrated graphics.
47
48	  This driver is used by the Intel driver in X.org 6.8 and
49	  XFree86 4.4 and above. It replaces the older i830 module that
50	  supported a subset of the hardware in older X.org releases.
51
52	  Note that the older i810/i815 chipsets require the use of the
53	  i810 driver instead, and the Atom z5xx series has an entirely
54	  different implementation.
55
56	  If "M" is selected, the module will be called i915.
57
58config DRM_I915_FORCE_PROBE
59	string "Force probe i915 for selected Intel hardware IDs"
60	depends on DRM_I915
61	help
62	  This is the default value for the i915.force_probe module
63	  parameter. Using the module parameter overrides this option.
64
65	  Force probe the i915 driver for Intel graphics devices that are
66	  recognized but not properly supported by this kernel version. Force
67	  probing an unsupported device taints the kernel. It is recommended to
68	  upgrade to a kernel version with proper support as soon as it is
69	  available.
70
71	  It can also be used to block the probe of recognized and fully
72	  supported devices.
73
74	  Use "" to disable force probe. If in doubt, use this.
75
76	  Use "<pci-id>[,<pci-id>,...]" to force probe the i915 for listed
77	  devices. For example, "4500" or "4500,4571".
78
79	  Use "*" to force probe the driver for all known devices. Not
80	  recommended.
81
82	  Use "!" right before the ID to block the probe of the device. For
83	  example, "4500,!4571" forces the probe of 4500 and blocks the probe of
84	  4571.
85
86	  Use "!*" to block the probe of the driver for all known devices.

88config DRM_I915_CAPTURE_ERROR

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

105	help
106	  This option selects ZLIB_DEFLATE if it isn't already
107	  selected and causes any error state captured upon a GPU hang
108	  to be compressed using zlib.

137	  With GVT-g, it's possible to have one integrated graphics
138	  device shared by multiple VMs under KVM.
139
