[PATCH 0/2] x86/video: improve early video detection

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

Hello,

The current video logic reports wrong values when booted in PVH mode, as
that boot path explicitly skips real-mode logic, and thus avoids any VGA
video detection.

First patch is cleanup of the offset declarations in boot_video_info.
Second patch attempts to fix Xen in PVH mode reporting VGA support.

Roger Pau Monne (2):
  x86/video: add boot_video_info offset generation to asm-offsets
  x86/video: do not assume a video mode to be unconditionally present
