It replaces the older i830 module that 50 supported a subset of the hardware in older X.org releases. 51 52 Note that the older i810/i815 chipsets require the use of the 53 i810 driver instead, and the Atom z5xx series has an entirely 54 different implementation. 55 56 If "M" is selected, the module will be called i915. 57 58config DRM_I915_FORCE_PROBE 59 string "Force probe i915 for selected Intel hardware IDs" 60 depends on DRM_I915 61 help 62 This is the default value for the i915.force_probe module 63 parameter. Using the module parameter overrides this option. 64 65 Force probe the i915 driver for Intel graphics devices that are 66 recognized but not properly supported by this kernel version. Force 67 probing an unsupported device taints the kernel. It is recommended to 68 upgrade to a kernel version with proper support as soon as it is 69 available. 70 71 It can also be used to block the probe of recognized and fully 72 supported devices. 73 74 Use "" to disable force probe. If in doubt, use this. 75 76 Use "<pci-id>[,<pci-id>,...]" to force probe the i915 for listed 77 devices. For example, "4500" or "4500,4571". 78 79 Use "*" to force probe the driver for all known devices. Not 80 recommended. 81 82 Use "!" right before the ID to block the probe of the device. For 83 example, "4500,!4571" forces the probe of 4500 and blocks the probe of 84 4571. 85 86 Use "!*" to block the probe of the driver for all known devices. 87 88config DRM_I915_CAPTURE_ERROR 89 bool "Enable capturing GPU state following a hang" 90 depends on DRM_I915 91 default y 92 help 93 This option enables capturing the GPU state when a hang is detected. 94 This information is vital for triaging hangs and assists in debugging. 95 Please report any hang for triaging according to: 96 https://drm.pages.freedesktop.org/intel-docs/how-to-file-i915-bugs.html 97 98 If in doubt, say "Y". 99 100config DRM_I915_COMPRESS_ERROR 101 bool "Compress GPU error state" 102 depends on DRM_I915_CAPTURE_ERROR 103 select ZLIB_DEFLATE 104 default y 105 help 106 This option selects ZLIB_DEFLATE if it isn't already 107 selected and causes any error state captured upon a GPU hang 108 to be compressed using zlib. 109 110 If in doubt, say "Y". 111 112config DRM_I915_USERPTR 113 bool "Always enable userptr support" 114 depends on DRM_I915 115 select MMU_NOTIFIER 116 default y 117 help 118 This option selects CONFIG_MMU_NOTIFIER if it isn't already 119 selected to enabled full userptr support. 120 121 If in doubt, say "Y". 122 123config DRM_I915_GVT_KVMGT 124 tristate "Enable KVM host support Intel GVT-g graphics virtualization" 125 depends on DRM_I915 126 depends on X86 127 depends on 64BIT 128 depends on KVM 129 depends on VFIO 130 select DRM_I915_GVT 131 select KVM_EXTERNAL_WRITE_TRACKING 132 select VFIO_MDEV 133 134 help 135 Choose this option if you want to enable Intel GVT-g graphics 136 virtualization technology host support with integrated graphics. 137 With GVT-g, it's possible to have one integrated graphics 138 device shared by multiple VMs under KVM. 139 140 Note that this driver only supports newer device from Broadwell on. 141 For further information and setup guide, you can visit: 142 https://github.com/intel/gvt-linux/wiki. 143 144 If in doubt, say "N". 145 146config DRM_I915_PXP 147 bool "Enable Intel PXP support" 148 depends on DRM_I915 149 depends on INTEL_MEI && INTEL_MEI_PXP 150 default n 151 help 152 PXP (Protected Xe Path) is an i915 component, available on graphics 153 version 12 and newer GPUs, that helps to establish the hardware 154 protected session and manage the status of the alive software session, 155 as well as its life cycle. 156 157config DRM_I915_DP_TUNNEL 158 bool "Enable DP tunnel support" 159 depends on DRM_I915 160 depends on USB4 161 select DRM_DISPLAY_DP_TUNNEL 162 default y 163 help 164 Choose this option to detect DP tunnels and enable the Bandwidth 165 Allocation mode for such tunnels.
