This series of patches adds a nice BIOS startup splash screen.

It adds a "-splash" option allowing to specify the picture file name (a 640x480 (or less) and true color PNG) to display. You can enable/disable a fade in,
fade out and the bootmenu. The time to display the image can be also given (in
seconds).

Idea stollen from VirtualBox.

* [Qemu-devel] [PATCH 2/2][v2][QEMU] Add BIOS splash image

  To: kvm developers; +Cc: bochs developers, qemu developers, Laurent Vivier

This patch adds to qemu the functions needed to display a splash image
under BIOS control through the firmware control device.

It adds a "-splash" option allowing to specify the picture file name (a
.PNG) to display. You can enable/disable a fade in, fade out and the
bootmenu. The time to display the image can be also given (in seconds).

Can you resubmit against QEMU and upstream bochs?  I've done the port 
myself, it's pretty easy.

So my general feeling here is that this code is well isolated and 
provides a feature that some people will find interesting.  I know I 
personally am interested in this feature.  I also think that a good 
number of vendors will want to use this mechanism to brand their 
virtualization offerings.

So I'm inclined to take this patch set unless there is objection.  I 
don't necessarily disagree with some of the feedback about making the 
BIOS not delay at all but I think that's an orthogonal discussion to 
this one.  The Press F12 thing also annoys me and I'd be happy to look 
at patches to make it optional.

Anthony Liguori

Maybe having a default splash image in the same directory as the BIOS
binary, with hardcoded path, would make sense?  Then instead of adding
-splash you could override with -L.  A linux distribution could
override it too.

Cheers

This is what I did primarily, but I don't like hardcoded values... and  
using "-splash" allows to provide more than the file name.

I think we should leave -splash to allow people to control it but I also 
like the idea of having a default splash for QEMU.  If someone out there 
is good with gimp, please post splash screens and we can consider a 
default :-)

N.B. If we do this, the prompt=off stuff would disable the splash.  We 
should also prevent the VGA BIOS from writing to the screen during boot 
but we can do this all as follow up.

Anthony Liguori
