It replaces the older i830 module that 48 supported a subset of the hardware in older X.org releases. 49 50 Note that the older i810/i815 chipsets require the use of the 51 i810 driver instead, and the Atom z5xx series has an entirely 52 different implementation. 53 54 If "M" is selected, the module will be called i915. 55 56config DRM_I915_FORCE_PROBE 57 string "Force probe i915 for selected Intel hardware IDs" 58 depends on DRM_I915 59 help 60 This is the default value for the i915.force_probe module 61 parameter. Using the module parameter overrides this option. 62 63 Force probe the i915 driver for Intel graphics devices that are 64 recognized but not properly supported by this kernel version. Force 65 probing an unsupported device taints the kernel. It is recommended to 66 upgrade to a kernel version with proper support as soon as it is 67 available. 68 69 It can also be used to block the probe of recognized and fully 70 supported devices. 71 72 Use "" to disable force probe. If in doubt, use this. 73 74 Use "<pci-id>[,<pci-id>,...]" to force probe the i915 for listed 75 devices. For example, "4500" or "4500,4571". 76 77 Use "*" to force probe the driver for all known devices. Not 78 recommended. 79 80 Use "!" right before the ID to block the probe of the device. For 81 example, "4500,!4571" forces the probe of 4500 and blocks the probe of 82 4571. 83 84 Use "!*" to block the probe of the driver for all known devices. 85 86config DRM_I915_CAPTURE_ERROR 87 bool "Enable capturing GPU state following a hang" 88 depends on DRM_I915 89 default y 90 help 91 This option enables capturing the GPU state when a hang is detected. 92 This information is vital for triaging hangs and assists in debugging. 93 Please report any hang for triaging according to: 94 https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs 95 96 If in doubt, say "Y". 97 98config DRM_I915_COMPRESS_ERROR 99 bool "Compress GPU error state" 100 depends on DRM_I915_CAPTURE_ERROR 101 select ZLIB_DEFLATE 102 default y 103 help 104 This option selects ZLIB_DEFLATE if it isn't already 105 selected and causes any error state captured upon a GPU hang 106 to be compressed using zlib. 107 108 If in doubt, say "Y". 109 110config DRM_I915_USERPTR 111 bool "Always enable userptr support" 112 depends on DRM_I915 113 select MMU_NOTIFIER 114 default y 115 help 116 This option selects CONFIG_MMU_NOTIFIER if it isn't already 117 selected to enabled full userptr support. 118 119 If in doubt, say "Y". 120 121config DRM_I915_GVT_KVMGT 122 tristate "Enable KVM host support Intel GVT-g graphics virtualization" 123 depends on DRM_I915 124 depends on X86 125 depends on 64BIT 126 depends on KVM 127 depends on VFIO_MDEV 128 select DRM_I915_GVT 129 select KVM_EXTERNAL_WRITE_TRACKING 130 131 help 132 Choose this option if you want to enable Intel GVT-g graphics 133 virtualization technology host support with integrated graphics. 134 With GVT-g, it's possible to have one integrated graphics 135 device shared by multiple VMs under KVM. 136 137 Note that this driver only supports newer device from Broadwell on. 138 For further information and setup guide, you can visit: 139 http://01.org/igvt-g. 140 141 If in doubt, say "N". 142 143config DRM_I915_PXP 144 bool "Enable Intel PXP support" 145 depends on DRM_I915 146 depends on INTEL_MEI && INTEL_MEI_PXP 147 default n 148 help 149 PXP (Protected Xe Path) is an i915 component, available on graphics 150 version 12 and newer GPUs, that helps to establish the hardware 151 protected session and manage the status of the alive software session, 152 as well as its life cycle. 153 154menu "drm/i915 Debugging" 155depends on DRM_I915 156depends on EXPERT 157source "drivers/gpu/drm/i915/Kconfig.debug" 158endmenu 159 160menu "drm/i915 Profile Guided Optimisation" 161 visible if EXPERT 162 depends on DRM_I915 163 source "drivers/gpu/drm/i915/Kconfig.profile" 164endmenu 165 166menu "drm/i915 Unstable Evolution" 167 visible if EXPERT && STAGING && BROKEN 168 depends on DRM_I915 169 source "drivers/gpu/drm/i915/Kconfig.unstable" 170endmenu 171 172config DRM_I915_GVT 173 bool 174
