31 Choose this option if you have a system that has "Intel Graphics
32 Media Accelerator" or "HD Graphics" integrated graphics,
33 including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
34 G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
35 Core i5, Core i7 as well as Atom CPUs with integrated graphics.
37 This driver is used by the Intel driver in X.org 6.8 and
38 XFree86 4.4 and above. It replaces the older i830 module that
39 supported a subset of the hardware in older X.org releases.
41 Note that the older i810/i815 chipsets require the use of the
42 i810 driver instead, and the Atom z5xx series has an entirely
43 different implementation.
45 If "M" is selected, the module will be called i915.
47 config DRM_I915_FORCE_PROBE
48 string "Force probe driver for selected new Intel hardware"
51 This is the default value for the i915.force_probe module
52 parameter. Using the module parameter overrides this option.
54 Force probe the driver for new Intel graphics devices that are
55 recognized but not properly supported by this kernel version. It is
56 recommended to upgrade to a kernel version with proper support as soon
59 Use "" to disable force probe. If in doubt, use this.
61 Use "<pci-id>[,<pci-id>,...]" to force probe the driver for listed
62 devices. For example, "4500" or "4500,4571".
64 Use "*" to force probe the driver for all known devices.
66 config DRM_I915_CAPTURE_ERROR
67 bool "Enable capturing GPU state following a hang"
71 This option enables capturing the GPU state when a hang is detected.
72 This information is vital for triaging hangs and assists in debugging.
73 Please report any hang for triaging according to:
74 https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs
78 config DRM_I915_COMPRESS_ERROR
79 bool "Compress GPU error state"
80 depends on DRM_I915_CAPTURE_ERROR
84 This option selects ZLIB_DEFLATE if it isn't already
85 selected and causes any error state captured upon a GPU hang
86 to be compressed using zlib.
90 config DRM_I915_USERPTR
91 bool "Always enable userptr support"
96 This option selects CONFIG_MMU_NOTIFIER if it isn't already
97 selected to enabled full userptr support.
102 bool "Enable Intel GVT-g graphics virtualization host support"
108 Choose this option if you want to enable Intel GVT-g graphics
109 virtualization technology host support with integrated graphics.
110 With GVT-g, it's possible to have one integrated graphics
111 device shared by multiple VMs under different hypervisors.
113 Note that at least one hypervisor like Xen or KVM is required for
114 this driver to work, and it only supports newer device from
115 Broadwell+. For further information and setup guide, you can
116 visit: http://01.org/igvt-g.
118 Now it's just a stub to support the modifications of i915 for
119 GVT device model. It requires at least one MPT modules for Xen/KVM
120 and other components of GVT device model to work. Use it under
123 If in doubt, say "N".

127 depends on DRM_I915_GVT

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.
