I'm experiencing this bug too, looks like i915 has been changed/updated to
include the new xe driver and it's broken.
dmesg:
[ 2.740670] xe 0000:01:00.0: Your graphics device 56a6 is not officially
supported
by xe driver in this kernel version. To force Xe probe,
use xe.force_probe='56a6' and i915.force_probe='!56a6'
module parameters or CONFIG_DRM_XE_FORCE_PROBE='56a6' and
CONFIG_DRM_I915_FORCE_PROBE='!56a6' configuration options.
$ intel_gpu_top
No device filter specified and no discrete/integrated i915 devices found
$ lspci | grep DG2
01:00.0 VGA compatible controller: Intel Corporation DG2 [Arc A310] (rev 05)
02:00.0 Audio device: Intel Corporation DG2 Audio Controller
blacklisting the xe module makes the dmesg error go away but the gpu still
isn't available for use. My GPU is an Intel Arc A310.
