AGP support 28 is required for this driver to work. This driver is used by 29 the Intel driver in X.org 6.8 and XFree86 4.4 and above. It 30 replaces the older i830 module that supported a subset of the 31 hardware in older X.org releases. 32 33 Note that the older i810/i815 chipsets require the use of the 34 i810 driver instead, and the Atom z5xx series has an entirely 35 different implementation. 36 37config DRM_I915_PRELIMINARY_HW_SUPPORT 38 bool "Enable preliminary support for prerelease Intel hardware by default" 39 depends on DRM_I915 40 default n 41 help 42 Choose this option if you have prerelease Intel hardware and want the 43 i915 driver to support it by default. You can enable such support at 44 runtime with the module option i915.preliminary_hw_support=1; this 45 option changes the default for that module option. 46 47 If in doubt, say "N". 48 49config DRM_I915_CAPTURE_ERROR 50 bool "Enable capturing GPU state following a hang" 51 depends on DRM_I915 52 default y 53 help 54 This option enables capturing the GPU state when a hang is detected. 55 This information is vital for triaging hangs and assists in debugging. 56 Please report any hang to 57 https://bugs.freedesktop.org/enter_bug.cgi?product=DRI 58 for triaging. 59 60 If in doubt, say "Y". 61 62config DRM_I915_COMPRESS_ERROR 63 bool "Compress GPU error state" 64 depends on DRM_I915_CAPTURE_ERROR 65 select ZLIB_DEFLATE 66 default y 67 help 68 This option selects ZLIB_DEFLATE if it isn't already 69 selected and causes any error state captured upon a GPU hang 70 to be compressed using zlib. 71 72 If in doubt, say "Y". 73 74config DRM_I915_USERPTR 75 bool "Always enable userptr support" 76 depends on DRM_I915 77 select MMU_NOTIFIER 78 default y 79 help 80 This option selects CONFIG_MMU_NOTIFIER if it isn't already 81 selected to enabled full userptr support. 82 83 If in doubt, say "Y". 84 85config DRM_I915_GVT 86 bool "Enable Intel GVT-g graphics virtualization host support" 87 depends on DRM_I915 88 default n 89 help 90 Choose this option if you want to enable Intel GVT-g graphics 91 virtualization technology host support with integrated graphics. 92 With GVT-g, it's possible to have one integrated graphics 93 device shared by multiple VMs under different hypervisors. 94 95 Note that at least one hypervisor like Xen or KVM is required for 96 this driver to work, and it only supports newer device from 97 Broadwell+. For further information and setup guide, you can 98 visit: http://01.org/igvt-g. 99 100 Now it's just a stub to support the modifications of i915 for 101 GVT device model. It requires at least one MPT modules for Xen/KVM 102 and other components of GVT device model to work. Use it under 103 you own risk. 104 105 If in doubt, say "N". 106 107menu "drm/i915 Debugging" 108depends on DRM_I915 109depends on EXPERT 110source drivers/gpu/drm/i915/Kconfig.debug 111endmenu 112
