The diff from the post in "related" won't apply directly but you could
try what is basically rhe same thing by removing
.require_force_probe = 1,
from struct intel_device_info dg2_info in sys/dev/pci/drm/i915/i915_pci.c
If it doesn't work with 7.7 it may be worth trying again with -current
Hi! How this patch is unrelated with this issue?
In my case, I have a Intel Arc 380, in -current, the kernel don´t detect
the GPU, but with this first patch
- .require_force_probe = 1,
The GPU is detected, but it's not fully initialized and therefore unusable.
In the related thread, @jsg mentions other patches, but ultimately other
issues prevent proper initialization (VGA arbitrer), and @tfrohwein
tests with A750, give same errors.
