It replaces the older i830 module that 37 supported a subset of the hardware in older X.org releases. 38 39 Note that the older i810/i815 chipsets require the use of the 40 i810 driver instead, and the Atom z5xx series has an entirely 41 different implementation. 42 43 If "M" is selected, the module will be called i915. 44 45config DRM_I915_ALPHA_SUPPORT 46 bool "Enable alpha quality support for new Intel hardware by default" 47 depends on DRM_I915 48 default n 49 help 50 Choose this option if you have new Intel hardware and want to enable 51 the alpha quality i915 driver support for the hardware in this kernel 52 version. You can also enable the support at runtime using the module 53 parameter i915.alpha_support=1; this option changes the default for 54 that module parameter. 55 56 It is recommended to upgrade to a kernel version with proper support 57 as soon as it is available. Generally fixes for platforms with alpha 58 support are not backported to older kernels. 59 60 If in doubt, say "N". 61 62config DRM_I915_CAPTURE_ERROR 63 bool "Enable capturing GPU state following a hang" 64 depends on DRM_I915 65 default y 66 help 67 This option enables capturing the GPU state when a hang is detected. 68 This information is vital for triaging hangs and assists in debugging. 69 Please report any hang to 70 https://bugs.freedesktop.org/enter_bug.cgi?product=DRI 71 for triaging. 72 73 If in doubt, say "Y". 74 75config DRM_I915_COMPRESS_ERROR 76 bool "Compress GPU error state" 77 depends on DRM_I915_CAPTURE_ERROR 78 select ZLIB_DEFLATE 79 default y 80 help 81 This option selects ZLIB_DEFLATE if it isn't already 82 selected and causes any error state captured upon a GPU hang 83 to be compressed using zlib. 84 85 If in doubt, say "Y". 86 87config DRM_I915_USERPTR 88 bool "Always enable userptr support" 89 depends on DRM_I915 90 select MMU_NOTIFIER 91 default y 92 help 93 This option selects CONFIG_MMU_NOTIFIER if it isn't already 94 selected to enabled full userptr support. 95 96 If in doubt, say "Y". 97 98config DRM_I915_GVT 99 bool "Enable Intel GVT-g graphics virtualization host support" 100 depends on DRM_I915 101 depends on 64BIT 102 default n 103 help 104 Choose this option if you want to enable Intel GVT-g graphics 105 virtualization technology host support with integrated graphics. 106 With GVT-g, it's possible to have one integrated graphics 107 device shared by multiple VMs under different hypervisors. 108 109 Note that at least one hypervisor like Xen or KVM is required for 110 this driver to work, and it only supports newer device from 111 Broadwell+.
