40 Choose this option if you have a system that has "Intel Graphics
41 Media Accelerator" or "HD Graphics" integrated graphics,
42 including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
43 G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
44 Core i5, Core i7 as well as Atom CPUs with integrated graphics.
46 This driver is used by the Intel driver in X.org 6.8 and
47 XFree86 4.4 and above. It replaces the older i830 module that
48 supported a subset of the hardware in older X.org releases.
50 Note that the older i810/i815 chipsets require the use of the
51 i810 driver instead, and the Atom z5xx series has an entirely
52 different implementation.
54 If "M" is selected, the module will be called i915.
56 config DRM_I915_FORCE_PROBE
57 string "Force probe driver for selected new Intel hardware"
60 This is the default value for the i915.force_probe module
61 parameter. Using the module parameter overrides this option.
63 Force probe the driver for new Intel graphics devices that are
64 recognized but not properly supported by this kernel version. It is
65 recommended to upgrade to a kernel version with proper support as soon
68 Use "" to disable force probe. If in doubt, use this.
70 Use "<pci-id>[,<pci-id>,...]" to force probe the driver for listed
71 devices. For example, "4500" or "4500,4571".
73 Use "*" to force probe the driver for all known devices.
75 config DRM_I915_CAPTURE_ERROR
76 bool "Enable capturing GPU state following a hang"
80 This option enables capturing the GPU state when a hang is detected.
81 This information is vital for triaging hangs and assists in debugging.
82 Please report any hang for triaging according to:
83 https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs
87 config DRM_I915_COMPRESS_ERROR
88 bool "Compress GPU error state"
89 depends on DRM_I915_CAPTURE_ERROR
93 This option selects ZLIB_DEFLATE if it isn't already
94 selected and causes any error state captured upon a GPU hang
95 to be compressed using zlib.
99 config DRM_I915_USERPTR
100 bool "Always enable userptr support"
105 This option selects CONFIG_MMU_NOTIFIER if it isn't already
106 selected to enabled full userptr support.
108 If in doubt, say "Y".
113 config DRM_I915_GVT_KVMGT
114 tristate "Enable KVM host support Intel GVT-g graphics virtualization"
121 select KVM_EXTERNAL_WRITE_TRACKING
125 Choose this option if you want to enable Intel GVT-g graphics
126 virtualization technology host support with integrated graphics.
127 With GVT-g, it's possible to have one integrated graphics
128 device shared by multiple VMs under KVM.
130 Note that this driver only supports newer device from Broadwell on.
131 For further information and setup guide, you can visit:
132 http://01.org/igvt-g.
134 If in doubt, say "N".
137 bool "Enable Intel PXP support"
139 depends on INTEL_MEI && INTEL_MEI_PXP
142 PXP (Protected Xe Path) is an i915 component, available on graphics
143 version 12 and newer GPUs, that helps to establish the hardware
144 protected session and manage the status of the alive software session,
145 as well as its life cycle.
