Subject: [PATCH 0/2] x86/video: improve early video detection
Date: Thu, 28 Mar 2024 16:35:21 +0100	[thread overview]
Message-ID: <20240328153523.4155-1-roger.pau@citrix.com> (raw)

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
