It turns out that xe is performing all kinds of allocations before
inheriting the BIOS fb. This is problematic as it completely overwrites
the initial FB on discrete, and on integrated causes flickering until
the original FB is restored (preserved in stolen memory).
The complete fix requires reshuffling the entire init sequence. I want to
do that, but first add some preparations. This way I don't need to resubmit
all these patches that are ready to commit each time.
Maarten Lankhorst (12):
drm/xe/display: Handle stolen bar readout in the same way as lmem
drm/xe: Remove double pageflip
drm/i915/display: Use async flip when available for initial plane
config
drm/xe/display: Remove single wait for vblank
drm/xe: Move suballocator init to after display init
drm/xe: Use xe_ggtt_map_bo_unlocked for resume
drm/xe: Add xe_ggtt_might_lock
drm/xe: Add xe_ggtt_alloc
drm/xe: Abstract read/write functions for GGTT PTEs
drm/xe: Make xe_ggtt_pt_ops private
drm/xe/display: Stop dereferencing ggtt in xe_fb_pin
drm/xe: Move struct xe_ggtt to xe_ggtt.c
