It replaces the older i830 module that 52 supported a subset of the hardware in older X.org releases. 53 54 Note that the older i810/i815 chipsets require the use of the 55 i810 driver instead, and the Atom z5xx series has an entirely 56 different implementation. 57 58 If "M" is selected, the module will be called i915. 59 60config DRM_I915_FORCE_PROBE 61 string "Force probe i915 for selected Intel hardware IDs" 62 depends on DRM_I915 63 help 64 This is the default value for the i915.force_probe module 65 parameter.

Force 69 probing an unsupported device taints the kernel.

If in doubt, use this. 77 78 Use "<pci-id>[,<pci-id>,...]" to force probe the i915 for listed 79 devices.

For 85 example, "4500,!4571" forces the probe of 4500 and blocks the probe of 86 4571. 87 88 Use "!*" to block the probe of the driver for all known devices. 89 90config DRM_I915_CAPTURE_ERROR 91 bool "Enable capturing GPU state following a hang" 92 depends on DRM_I915 93 default y 94 help 95 This option enables capturing the GPU state when a hang is detected. 96 This information is vital for triaging hangs and assists in debugging. 97 Please report any hang for triaging according to: 98 https://drm.pages.freedesktop.org/intel-docs/how-to-file-i915-bugs.html 99 100 If in doubt, say "Y". 101 102config DRM_I915_COMPRESS_ERROR 103 bool "Compress GPU error state" 104 depends on DRM_I915_CAPTURE_ERROR 105 select ZLIB_DEFLATE 106 default y 107 help 108 This option selects ZLIB_DEFLATE if it isn't already 109 selected and causes any error state captured upon a GPU hang 110 to be compressed using zlib. 111 112 If in doubt, say "Y". 113 114config DRM_I915_USERPTR 115 bool "Always enable userptr support" 116 depends on DRM_I915 117 select MMU_NOTIFIER 118 default y 119 help 120 This option selects CONFIG_MMU_NOTIFIER if it isn't already 121 selected to enabled full userptr support. 122 123 If in doubt, say "Y". 124 125config DRM_I915_GVT_KVMGT 126 tristate "Enable KVM host support Intel GVT-g graphics virtualization" 127 depends on DRM_I915 128 depends on KVM_X86 129 depends on 64BIT 130 depends on VFIO 131 select DRM_I915_GVT 132 select KVM_EXTERNAL_WRITE_TRACKING 133 select VFIO_MDEV 134 135 help 136 Choose this option if you want to enable Intel GVT-g graphics 137 virtualization technology host support with integrated graphics. 138 With GVT-g, it's possible to have one integrated graphics 139 device shared by multiple VMs under KVM. 140 141 Note that this driver only supports newer device from Broadwell on. 142 For further information and setup guide, you can visit: 143 https://github.com/intel/gvt-linux/wiki. 144 145 If in doubt, say "N". 146 147config DRM_I915_PXP 148 bool "Enable Intel PXP support" 149 depends on DRM_I915 150 depends on INTEL_MEI && INTEL_MEI_PXP 151 default n 152 help 153 PXP (Protected Xe Path) is an i915 component, available on graphics 154 version 12 and newer GPUs, that helps to establish the hardware 155 protected session and manage the status of the alive software session, 156 as well as its life cycle. 157 158config DRM_I915_DP_TUNNEL 159 bool "Enable DP tunnel support" 160 depends on DRM_I915 161 depends on USB4 162 select DRM_DISPLAY_DP_TUNNEL 163 default y 164 help 165 Choose this option to detect DP tunnels and enable the Bandwidth 166 Allocation mode for such tunnels.
