[PATCH 00/14] drm/{i915,xe}: BIOS FB takeover fixes

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Try to fix the BIOS FB readout to actually work on xe+integrated GPUs.
It's still semi-crap due to the xe ggtt code being stupid, but at 
least it kinda works now.

I've also included some generic BIOS FB stuff that applies to both
i915 and xe, and I fixed a few minor issues in the i915 specific parts
as well.

Ville Syrjälä (14):
  drm/i915: Disable the plane if initial plane config readout failed
  drm/i915/fbdev: Extract bios_fb_ok()
  drm/i915: Throw away the BIOS fb if has the wrong depth/bpp
  drm/i915: Introduce intel_bo_fbdev_bios_fb_ok()
  drm/i915: Use drm_dbg_kms() for initial FB debugs
  drm/xe: Do the initial FB size alignment earlier
  drm/xe/ggtt: Decouple lmem/stolen physcial offset from GGTT offset
  drm/xe: Print a debug message if we have no stolen for the initial FB
  drm/xe: Abstract the initial FB PTE checks a bit
  drm/xe: Check the PTE local memory bit for initial FB in stolen
  drm/xe: s/bar2/lmembar/
  drm/xe: Use the correct stolen offset in initial FB readout
  drm/i915: Fix BIOS FB memory region name debug prints
  drm/i915: Print the phys_base in addition to the dma_addr for the BIOS
    FB
