7 # we need shmfs for the swappable backing store, and in particular
8 # the shmem_readpage() which depends upon tmpfs
16 # i915 depends on ACPI_VIDEO when ACPI is enabled
17 # but for select to work, need to select ACPI_VIDEO's dependencies, ick
18 select BACKLIGHT_CLASS_DEVICE if ACPI
20 select ACPI_VIDEO if ACPI
21 select ACPI_BUTTON if ACPI
25 select SND_HDA_I915 if SND_HDA_CORE
26 select CEC_CORE if CEC_NOTIFIER
28 Choose this option if you have a system that has "Intel Graphics
29 Media Accelerator" or "HD Graphics" integrated graphics,
30 including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
31 G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
32 Core i5, Core i7 as well as Atom CPUs with integrated graphics.
34 This driver is used by the Intel driver in X.org 6.8 and
35 XFree86 4.4 and above. It replaces the older i830 module that
36 supported a subset of the hardware in older X.org releases.
38 Note that the older i810/i815 chipsets require the use of the
39 i810 driver instead, and the Atom z5xx series has an entirely
40 different implementation.
42 If "M" is selected, the module will be called i915.
44 config DRM_I915_ALPHA_SUPPORT
45 bool "Enable alpha quality support for new Intel hardware by default"
49 Choose this option if you have new Intel hardware and want to enable
50 the alpha quality i915 driver support for the hardware in this kernel
51 version. You can also enable the support at runtime using the module
52 parameter i915.alpha_support=1; this option changes the default for
53 that module parameter.
55 It is recommended to upgrade to a kernel version with proper support
56 as soon as it is available. Generally fixes for platforms with alpha
57 support are not backported to older kernels.
61 config DRM_I915_CAPTURE_ERROR
62 bool "Enable capturing GPU state following a hang"
66 This option enables capturing the GPU state when a hang is detected.
67 This information is vital for triaging hangs and assists in debugging.
68 Please report any hang to
69 https://bugs.freedesktop.org/enter_bug.cgi?product=DRI
74 config DRM_I915_COMPRESS_ERROR
75 bool "Compress GPU error state"
76 depends on DRM_I915_CAPTURE_ERROR
80 This option selects ZLIB_DEFLATE if it isn't already
81 selected and causes any error state captured upon a GPU hang
82 to be compressed using zlib.
86 config DRM_I915_USERPTR
87 bool "Always enable userptr support"
92 This option selects CONFIG_MMU_NOTIFIER if it isn't already
93 selected to enabled full userptr support.
98 bool "Enable Intel GVT-g graphics virtualization host support"
103 Choose this option if you want to enable Intel GVT-g graphics
104 virtualization technology host support with integrated graphics.
105 With GVT-g, it's possible to have one integrated graphics
106 device shared by multiple VMs under different hypervisors.
108 Note that at least one hypervisor like Xen or KVM is required for
109 this driver to work, and it only supports newer device from
110 Broadwell+. For further information and setup guide, you can
111 visit: http://01.org/igvt-g.
113 Now it's just a stub to support the modifications of i915 for
114 GVT device model. It requires at least one MPT modules for Xen/KVM
115 and other components of GVT device model to work. Use it under
118 If in doubt, say "N".
120 config DRM_I915_GVT_KVMGT
121 tristate "Enable KVM/VFIO support for Intel GVT-g"
122 depends on DRM_I915_GVT
124 depends on VFIO_MDEV && VFIO_MDEV_DEVICE
127 Choose this option if you want to enable KVMGT support for
