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
