29	  Choose this option if you have a system that has "Intel Graphics
30	  Media Accelerator" or "HD Graphics" integrated graphics,
31	  including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
32	  G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
33	  Core i5, Core i7 as well as Atom CPUs with integrated graphics.
34
35	  This driver is used by the Intel driver in X.org 6.8 and
36	  XFree86 4.4 and above. It replaces the older i830 module that
37	  supported a subset of the hardware in older X.org releases.
38
39	  Note that the older i810/i815 chipsets require the use of the
40	  i810 driver instead, and the Atom z5xx series has an entirely
41	  different implementation.
42
43	  If "M" is selected, the module will be called i915.

55	help
56	  This is the default value for the i915.force_probe module
57	  parameter. Using the module parameter overrides this option.
58
59	  Force probe the driver for new Intel graphics devices that are
60	  recognized but not properly supported by this kernel version. It is
61	  recommended to upgrade to a kernel version with proper support as soon
62	  as it is available.
63
64	  Use "" to disable force probe. If in doubt, use this.
65
66	  Use "<pci-id>[,<pci-id>,...]" to force probe the driver for listed
67	  devices. For example, "4500" or "4500,4571".
68
69	  Use "*" to force probe the driver for all known devices.

74	default y
75	help
76	  This option enables capturing the GPU state when a hang is detected.
77	  This information is vital for triaging hangs and assists in debugging.
78	  Please report any hang for triaging according to:
79	    https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs
80
81	  If in doubt, say "Y".

88	help
89	  This option selects ZLIB_DEFLATE if it isn't already
90	  selected and causes any error state captured upon a GPU hang
91	  to be compressed using zlib.

101	  This option selects CONFIG_MMU_NOTIFIER if it isn't already

107	bool "Enable Intel GVT-g graphics virtualization host support"

110	default n
111	help
112	  Choose this option if you want to enable Intel GVT-g graphics
113	  virtualization technology host support with integrated graphics.
114	  With GVT-g, it's possible to have one integrated graphics
115	  device shared by multiple VMs under different hypervisors.
116
117	  Note that at least one hypervisor like Xen or KVM is required for
118	  this driver to work, and it only supports newer device from
119	  Broadwell+. For further information and setup guide, you can
120	  visit: http://01.org/igvt-g.
121
122	  Now it's just a stub to support the modifications of i915 for
123	  GVT device model. It requires at least one MPT modules for Xen/KVM
124	  and other components of GVT device model to work. Use it under
125	  you own risk.
126
127	  If in doubt, say "N".
