38	  Choose this option if you have a system that has "Intel Graphics
39	  Media Accelerator" or "HD Graphics" integrated graphics,
40	  including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
41	  G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
42	  Core i5, Core i7 as well as Atom CPUs with integrated graphics.
43
44	  This driver is used by the Intel driver in X.org 6.8 and
45	  XFree86 4.4 and above. It replaces the older i830 module that
46	  supported a subset of the hardware in older X.org releases.
47
48	  Note that the older i810/i815 chipsets require the use of the
49	  i810 driver instead, and the Atom z5xx series has an entirely
50	  different implementation.
51
52	  If "M" is selected, the module will be called i915.

57	help
58	  This is the default value for the i915.force_probe module
59	  parameter. Using the module parameter overrides this option.
60
61	  Force probe the driver for new Intel graphics devices that are
62	  recognized but not properly supported by this kernel version. It is
63	  recommended to upgrade to a kernel version with proper support as soon
64	  as it is available.
65
66	  Use "" to disable force probe. If in doubt, use this.
67
68	  Use "<pci-id>[,<pci-id>,...]" to force probe the driver for listed
69	  devices. For example, "4500" or "4500,4571".
70
71	  Use "*" to force probe the driver for all known devices.

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

90	help
91	  This option selects ZLIB_DEFLATE if it isn't already

93	  to be compressed using zlib.

113	default n
114	help
115	  Choose this option if you want to enable Intel GVT-g graphics
116	  virtualization technology host support with integrated graphics.
117	  With GVT-g, it's possible to have one integrated graphics
118	  device shared by multiple VMs under different hypervisors.
119
120	  Note that at least one hypervisor like Xen or KVM is required for
121	  this driver to work, and it only supports newer device from
122	  Broadwell+. For further information and setup guide, you can
123	  visit: http://01.org/igvt-g.
124
125	  Now it's just a stub to support the modifications of i915 for
126	  GVT device model. It requires at least one MPT modules for Xen/KVM
127	  and other components of GVT device model to work. Use it under
128	  you own risk.
129
130	  If in doubt, say "N".
