It replaces the older i830 module that 33 supported a subset of the hardware in older X.org releases. 34 35 Note that the older i810/i815 chipsets require the use of the 36 i810 driver instead, and the Atom z5xx series has an entirely 37 different implementation. 38 39 If "M" is selected, the module will be called i915. 40 41config DRM_I915_ALPHA_SUPPORT 42 bool "Enable alpha quality support for new Intel hardware by default" 43 depends on DRM_I915 44 default n 45 help 46 Choose this option if you have new Intel hardware and want to enable 47 the alpha quality i915 driver support for the hardware in this kernel 48 version. You can also enable the support at runtime using the module 49 parameter i915.alpha_support=1; this option changes the default for 50 that module parameter. 51 52 It is recommended to upgrade to a kernel version with proper support 53 as soon as it is available. Generally fixes for platforms with alpha 54 support are not backported to older kernels. 55 56 If in doubt, say "N". 57 58config DRM_I915_CAPTURE_ERROR 59 bool "Enable capturing GPU state following a hang" 60 depends on DRM_I915 61 default y 62 help 63 This option enables capturing the GPU state when a hang is detected. 64 This information is vital for triaging hangs and assists in debugging. 65 Please report any hang to 66 https://bugs.freedesktop.org/enter_bug.cgi?product=DRI 67 for triaging. 68 69 If in doubt, say "Y". 70 71config DRM_I915_COMPRESS_ERROR 72 bool "Compress GPU error state" 73 depends on DRM_I915_CAPTURE_ERROR 74 select ZLIB_DEFLATE 75 default y 76 help 77 This option selects ZLIB_DEFLATE if it isn't already 78 selected and causes any error state captured upon a GPU hang 79 to be compressed using zlib. 80 81 If in doubt, say "Y". 82 83config DRM_I915_USERPTR 84 bool "Always enable userptr support" 85 depends on DRM_I915 86 select MMU_NOTIFIER 87 default y 88 help 89 This option selects CONFIG_MMU_NOTIFIER if it isn't already 90 selected to enabled full userptr support. 91 92 If in doubt, say "Y". 93 94config DRM_I915_GVT 95 bool "Enable Intel GVT-g graphics virtualization host support" 96 depends on DRM_I915 97 depends on 64BIT 98 default n 99 help 100 Choose this option if you want to enable Intel GVT-g graphics 101 virtualization technology host support with integrated graphics. 102 With GVT-g, it's possible to have one integrated graphics 103 device shared by multiple VMs under different hypervisors. 104 105 Note that at least one hypervisor like Xen or KVM is required for 106 this driver to work, and it only supports newer device from 107 Broadwell+.
