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.

76	default y
77	help
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
82

90	help
91	  This option selects ZLIB_DEFLATE if it isn't already
92	  selected and causes any error state captured upon a GPU hang
93	  to be compressed using zlib.
94

124	  With GVT-g, it's possible to have one integrated graphics
125	  device shared by multiple VMs under KVM.
126
