It replaces the older i830 module that 51 supported a subset of the hardware in older X.org releases. 52 53 Note that the older i810/i815 chipsets require the use of the 54 i810 driver instead, and the Atom z5xx series has an entirely 55 different implementation. 56 57 If "M" is selected, the module will be called i915. 58 59config DRM_I915_FORCE_PROBE 60 string "Force probe i915 for selected Intel hardware IDs" 61 depends on DRM_I915 62 help 63 This is the default value for the i915.force_probe module 64 parameter. Using the module parameter overrides this option. 65 66 Force probe the i915 driver for Intel graphics devices that are 67 recognized but not properly supported by this kernel version. Force 68 probing an unsupported device taints the kernel. It is recommended to 69 upgrade to a kernel version with proper support as soon as it is 70 available. 71 72 It can also be used to block the probe of recognized and fully 73 supported devices. 74 75 Use "" to disable force probe. If in doubt, use this. 76 77 Use "<pci-id>[,<pci-id>,...]" to force probe the i915 for listed 78 devices. For example, "4500" or "4500,4571". 79 80 Use "*" to force probe the driver for all known devices. Not 81 recommended. 82 83 Use "!" right before the ID to block the probe of the device. For 84 example, "4500,!4571" forces the probe of 4500 and blocks the probe of 85 4571. 86 87 Use "!*" to block the probe of the driver for all known devices. 88 89config DRM_I915_CAPTURE_ERROR 90 bool "Enable capturing GPU state following a hang" 91 depends on DRM_I915 92 default y 93 help 94 This option enables capturing the GPU state when a hang is detected. 95 This information is vital for triaging hangs and assists in debugging. 96 Please report any hang for triaging according to: 97 https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs 98 99 If in doubt, say "Y". 100 101config DRM_I915_COMPRESS_ERROR 102 bool "Compress GPU error state" 103 depends on DRM_I915_CAPTURE_ERROR 104 select ZLIB_DEFLATE 105 default y 106 help 107 This option selects ZLIB_DEFLATE if it isn't already 108 selected and causes any error state captured upon a GPU hang 109 to be compressed using zlib. 110 111 If in doubt, say "Y". 112 113config DRM_I915_USERPTR 114 bool "Always enable userptr support" 115 depends on DRM_I915 116 select MMU_NOTIFIER 117 default y 118 help 119 This option selects CONFIG_MMU_NOTIFIER if it isn't already 120 selected to enabled full userptr support. 121 122 If in doubt, say "Y". 123 124config DRM_I915_GVT_KVMGT 125 tristate "Enable KVM host support Intel GVT-g graphics virtualization" 126 depends on DRM_I915 127 depends on X86 128 depends on 64BIT 129 depends on KVM 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 http://01.org/igvt-g. 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 158menu "drm/i915 Debugging" 159depends on DRM_I915 160depends on EXPERT 161source "drivers/gpu/drm/i915/Kconfig.debug" 162endmenu 163 164menu "drm/i915 Profile Guided Optimisation" 165 visible if EXPERT 166 depends on DRM_I915 167 source "drivers/gpu/drm/i915/Kconfig.profile" 168endmenu 169 170config DRM_I915_GVT 171 bool 172
