#79799 — Bug#1042517: i915: oops for NULL pointer dereference on Intel HD Graphics P4000

Package: src:linux
Version: 6.4.4-1
Severity: important

Dear Maintainer,

i915 used to work well on my Intel HD Graphics P4000 in an Intel(R) Xeon(R) CPU
E3-1225 V2 when running Linux kernel 6.3.0-1 (6.3.7-1) and older, but on
6.4.4-1, it will oops for NULL pointer dereference as the attached kernel log
shows. This also hangs the sound card and holds the system from reboot.

i915 of linux 6.4.4-1 will neither oops on Intel GMA 4500MHD in GM45, nor on an
ordinary Intel HD Graphics 4000 in an Intel(R) Core(TM) i5-3427U CPU.

#79809 — Bug#1042517: Info received (Bug#1042517: Acknowledgement (i915: oops for NULL pointer dereference on Intel HD Graphics P4000))

Further inspection shows that this oops is caused by 
intel_display_device_probe() returning NULL in 
intel_device_info_driver_create() when Intel HD Graphics P4000 
(PCI:8086:016a) is probed, which is further caused by 
INTEL_IVB_Q_IDS(NULL) (struct { u32 devid; const struct 
intel_display_device_info *info;}{ 0x16a, NULL}) in 
drivers/gpu/drm/i915/display/intel_display_device.c being erroneously 
matched against Intel HD Graphics P4000.

Were you able to confirm that the upstream mentioned patch fixes the

Yes. After building and installing a linux 6.5~rc4-1~exp1a~test with this patch applied to, the i915 does never shout oops on an IVB D GT2 server any more.
