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

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

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

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

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

145	  PXP (Protected Xe Path) is an i915 component, available on graphics
146	  version 12 and newer GPUs, that helps to establish the hardware
147	  protected session and manage the status of the alive software session,
148	  as well as its life cycle.
