It replaces the older i830 module that 31 supported a subset of the 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 37 If "M" is selected, the module will be called i915. 38 39config DRM_I915_PRELIMINARY_HW_SUPPORT 40 bool "Enable preliminary support for prerelease Intel hardware by default" 41 depends on DRM_I915 42 default n 43 help 44 Choose this option if you have prerelease Intel hardware and want the 45 i915 driver to support it by default. You can enable such support at 46 runtime with the module option i915.preliminary_hw_support=1; this 47 option changes the default for that module option. 48 49 If in doubt, say "N". 50 51config DRM_I915_CAPTURE_ERROR 52 bool "Enable capturing GPU state following a hang" 53 depends on DRM_I915 54 default y 55 help 56 This option enables capturing the GPU state when a hang is detected. 57 This information is vital for triaging hangs and assists in debugging. 58 Please report any hang to 59 https://bugs.freedesktop.org/enter_bug.cgi?product=DRI 60 for triaging. 61 62 If in doubt, say "Y". 63 64config DRM_I915_COMPRESS_ERROR 65 bool "Compress GPU error state" 66 depends on DRM_I915_CAPTURE_ERROR 67 select ZLIB_DEFLATE 68 default y 69 help 70 This option selects ZLIB_DEFLATE if it isn't already 71 selected and causes any error state captured upon a GPU hang 72 to be compressed using zlib. 73 74 If in doubt, say "Y". 75 76config DRM_I915_USERPTR 77 bool "Always enable userptr support" 78 depends on DRM_I915 79 select MMU_NOTIFIER 80 default y 81 help 82 This option selects CONFIG_MMU_NOTIFIER if it isn't already 83 selected to enabled full userptr support. 84 85 If in doubt, say "Y". 86 87config DRM_I915_GVT 88 bool "Enable Intel GVT-g graphics virtualization host support" 89 depends on DRM_I915 90 depends on 64BIT 91 default n 92 help 93 Choose this option if you want to enable Intel GVT-g graphics 94 virtualization technology host support with integrated graphics. 95 With GVT-g, it's possible to have one integrated graphics 96 device shared by multiple VMs under different hypervisors. 97 98 Note that at least one hypervisor like Xen or KVM is required for 99 this driver to work, and it only supports newer device from 100 Broadwell+. For further information and setup guide, you can 101 visit: http://01.org/igvt-g. 102 103 Now it's just a stub to support the modifications of i915 for 104 GVT device model. It requires at least one MPT modules for Xen/KVM 105 and other components of GVT device model to work. Use it under 106 you own risk. 107 108 If in doubt, say "N". 109 110menu "drm/i915 Debugging" 111depends on DRM_I915 112depends on EXPERT 113source drivers/gpu/drm/i915/Kconfig.debug 114endmenu 115
