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