It gets set to\nfalse if there's no display after intel_display_device_probe(). However,\nthe display may also be disabled via fuses, detected at a later time in\nintel_display_device_info_runtime_init().\n\nIn this case, the xe driver does for_each_intel_crtc() on uninitialized\nmode config in xe_display_flush_cleanup_work(), leading to a NULL\npointer dereference, and generally calls display code with display info\ncleared.\n\nCheck for intel_display_device_present() after\nintel_display_device_info_runtime_init(), and reset\nxe->info.probe_display as necessary. Also do unset_display_features()\nfor completeness, although display runtime init has already done\nthat. This will need to be unified across all cases later.\n\nMove intel_display_device_info_runtime_init() call slightly earlier,\nsimilar to i915, to avoid a bunch of unnecessary setup for no display\ncases.\n\nNote #1: The xe driver has no business doing low level display plumbing\nlike for_each_intel_crtc() to begin with. It all needs to happen in\ndisplay code.\n\nNote #2: The actual bug is present already in commit 44e694958b95\n(\"drm/xe/display: Implement display support\"), but the oops was likely\nintroduced later at commit ddf6492e0e50 (\"drm/xe/display: Make display\nsuspend/resume work on discrete\").\n\n(cherry picked from commit 7c3eb9f47533220888a67266448185fd0775d4da)\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
