[Impact]
During bootup sequence there is a black screen when it's intended that BGRT
logo continues through bootup.
This is because the stream hasn't been marked for seamless boot and so the
amdgpu kernel module does a modeset which leaves a black screen until next
drawing.
[Test Plan]
Obtain Strix or Strix Halo design that has eDP panel that doesn't
support DSC. (DSC is incompatible with seamless boot).
Turn on drm.debug=0x106.
Verify that message "Marked stream for seamless boot optimization" is
viewed in logs.
NOTE: There are other reasons a black screen could occur during bootup.
The key point here is the new message which indicates that amdgpu has
adopted the seamless boot process.
[ Where problems could occur ]
AMD Strix or Strix Halo designs.
+
+ [Upstream changes]
+ These are to be merged for 6.19-rc for fixing this issue.
