From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Attempt to fix the mess around stolen memory, especially on MTL
with it's special (and apparenly broken) not-actually-lmem stolen.
The series is made up of roughtly three parts:
1. General refactoring/debug improvement for mem regions
2. Deal with the broken BAR stuff on MTL
3. Fix initial display plane readout for MTL
v2: Try to relocate the BIOS fb to start of ggtt to make
space for the GuC stuff at the top end of ggtt
v3: Skip ton VM guests as they won't have access to stolen directly
Annotate more initial fb takeover failure paths
Add the w/a numbers
v4: Check the magic pcode bit
Try to deal with xe fallout
