<pre>Chris, what you mean by "expected behaviour for your setup."
is because it seems the lack of stolen space?
[drm:i915_gem_object_create_stolen_for_preallocated [i915]] failed to allocate
stolen space
Probably something that needs to be adjustable on BIOS?
Comparing good x bad logs I just see that drm:drm_setup_crtcs()
is no longer called. Probably because drm_fb_helper_hotplug_event()
is not called anymore after this patch because it is protected now
by + if (ifbdev->vma).
Do we really need to sync on this vma for this hotplug event?
jrq, 1. could you please check if you have ways to increase the stolen memory?
2. IF 1 doesn't solve, could you please check if by removing this
- if (ifbdev->vma).
before drm_fb_helper_hotplug_event() call would get things working for you
back?</pre>
