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.

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.

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".

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.

138	  With GVT-g, it's possible to have one integrated graphics
139	  device shared by multiple VMs under KVM.
140
