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_LCD_SUPPORT if ACPI
19 select BACKLIGHT_CLASS_DEVICE if ACPI
21 select ACPI_VIDEO if ACPI
22 select ACPI_BUTTON if ACPI
27 Choose this option if you have a system that has "Intel Graphics
28 Media Accelerator" or "HD Graphics" integrated graphics,
29 including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
30 G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
31 Core i5, Core i7 as well as Atom CPUs with integrated graphics.
33 This driver is used by the Intel driver in X.org 6.8 and
34 XFree86 4.4 and above. It replaces the older i830 module that
35 supported a subset of the hardware in older X.org releases.
37 Note that the older i810/i815 chipsets require the use of the
38 i810 driver instead, and the Atom z5xx series has an entirely
39 different implementation.
41 If "M" is selected, the module will be called i915.
43 config DRM_I915_ALPHA_SUPPORT
44 bool "Enable alpha quality support for new Intel hardware by default"
48 Choose this option if you have new Intel hardware and want to enable
49 the alpha quality i915 driver support for the hardware in this kernel
50 version. You can also enable the support at runtime using the module
51 parameter i915.alpha_support=1; this option changes the default for
52 that module parameter.
54 It is recommended to upgrade to a kernel version with proper support
55 as soon as it is available. Generally fixes for platforms with alpha
56 support are not backported to older kernels.
60 config DRM_I915_CAPTURE_ERROR
61 bool "Enable capturing GPU state following a hang"
65 This option enables capturing the GPU state when a hang is detected.
66 This information is vital for triaging hangs and assists in debugging.
67 Please report any hang to
68 https://bugs.freedesktop.org/enter_bug.cgi?product=DRI
73 config DRM_I915_COMPRESS_ERROR
74 bool "Compress GPU error state"
75 depends on DRM_I915_CAPTURE_ERROR
79 This option selects ZLIB_DEFLATE if it isn't already
80 selected and causes any error state captured upon a GPU hang
81 to be compressed using zlib.
85 config DRM_I915_USERPTR
86 bool "Always enable userptr support"
91 This option selects CONFIG_MMU_NOTIFIER if it isn't already
92 selected to enabled full userptr support.
97 bool "Enable Intel GVT-g graphics virtualization host support"
102 Choose this option if you want to enable Intel GVT-g graphics
103 virtualization technology host support with integrated graphics.
104 With GVT-g, it's possible to have one integrated graphics
105 device shared by multiple VMs under different hypervisors.
107 Note that at least one hypervisor like Xen or KVM is required for
108 this driver to work, and it only supports newer device from
109 Broadwell+. For further information and setup guide, you can
110 visit: http://01.org/igvt-g.
112 Now it's just a stub to support the modifications of i915 for
113 GVT device model. It requires at least one MPT modules for Xen/KVM
114 and other components of GVT device model to work. Use it under
117 If in doubt, say "N".
119 config DRM_I915_GVT_KVMGT
120 tristate "Enable KVM/VFIO support for Intel GVT-g"
121 depends on DRM_I915_GVT
123 depends on VFIO_MDEV && VFIO_MDEV_DEVICE
126 Choose this option if you want to enable KVMGT support for
