  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.

  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.

  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.

 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
