33	  Choose this option if you have a system that has "Intel Graphics
34	  Media Accelerator" or "HD Graphics" integrated graphics,
35	  including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
36	  G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
37	  Core i5, Core i7 as well as Atom CPUs with integrated graphics.
38
39	  This driver is used by the Intel driver in X.org 6.8 and
40	  XFree86 4.4 and above. It replaces the older i830 module that
41	  supported a subset of the hardware in older X.org releases.
42
43	  Note that the older i810/i815 chipsets require the use of the
44	  i810 driver instead, and the Atom z5xx series has an entirely
45	  different implementation.
46
47	  If "M" is selected, the module will be called i915.

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

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

86	  This option selects ZLIB_DEFLATE if it isn't already

88	  to be compressed using zlib.

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