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.
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.
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.
48 If "M" is selected, the module will be called i915.
50 config DRM_I915_FORCE_PROBE
51 string "Force probe driver for selected new Intel hardware"
54 This is the default value for the i915.force_probe module
55 parameter. Using the module parameter overrides this option.
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
62 Use "" to disable force probe. If in doubt, use this.
64 Use "<pci-id>[,<pci-id>,...]" to force probe the driver for listed
65 devices. For example, "4500" or "4500,4571".
67 Use "*" to force probe the driver for all known devices.
69 config DRM_I915_CAPTURE_ERROR
70 bool "Enable capturing GPU state following a hang"
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
81 config DRM_I915_COMPRESS_ERROR
82 bool "Compress GPU error state"
83 depends on DRM_I915_CAPTURE_ERROR
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.
93 config DRM_I915_USERPTR
94 bool "Always enable userptr support"
99 This option selects CONFIG_MMU_NOTIFIER if it isn't already
100 selected to enabled full userptr support.
102 If in doubt, say "Y".
105 bool "Enable Intel GVT-g graphics virtualization host support"
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.
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.
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
126 If in doubt, say "N".

129 tristate "Enable KVM/VFIO support for Intel GVT-g"
130 depends on DRM_I915_GVT
133 select KVM_EXTERNAL_WRITE_TRACKING
136 Choose this option if you want to enable KVMGT support for
140 bool "Enable Intel PXP support"
142 depends on INTEL_MEI && INTEL_MEI_PXP
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.
