[PATCH 0/3] Add BIOS splash image support

[PATCH 0/3] Add BIOS splash image support

[Laurent Vivier]

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 fade in,
fade out and bootmenu. The time to display the image can be also given (in
seconds).

Idea and some parts of code are stollen from VirtualBox (GPLv2/CDDL).

[PATCH 1/3] Correct fw_cfg_add_callback()
[PATCH 2/3] [BIOS] Add splash image support
[PATCH 3/3] [QEMU] Add BIOS splash image

[PATCH 1/3] Correct fw_cfg_add_callback()

[Laurent Vivier]

This patch is needed to be able to register firmware configuration
device callback.
It is already included in qemu as commit r5978.

[PATCH 3/3] [QEMU] Add BIOS splash image

[Laurent Vivier]

This patch adds to qemu the function 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).

Nice. But shouldn't this be more generic, I think we want to use this
on OpenBIOS/Sparc (or PPC) too?

On second thought, there is no Gtk/Qt GUI because that is supposed to
be external to Qemu. By the same logic, why should there be any splash
screen? The external GUI can probably show it as easily using the same
Gtk/Qt/whatever. The control channel may still be needed.

Alternatively the BIOS could load the image and fade parameters from a
new ROM or from the configuration device and draw it to screen. This
would need some PNG support to BIOS, or that the image stored in raw
form.

You need it to be consistent on the SDL/VNC display.

Modern BIOSes have splash screens.  I don't see why our BIOS shouldn't 
have one too.

Yeah, having QEMU render to the VGA directly is a bit ugly.  It would be 
nicer if the BIOS actually rendered the image but I'm not sure I think 
we should reject the patch just because it doesn't.

Oh, I didn't consider the VNC case. Then it may be difficult for the
GUI to manage the boot screen.

Actually this way the image can be in full color even if the emulated
device was an EGA in text mode.

And you can provide the image name on the command line, and complexity
is in Qemu, not in BIOS.

But in fact, my first idea was to read the image data from the
configuration device (which is always possible with LOGO_CMD_OFFSET),
but when I saw how it has been done in VirtualBox, I though it was a
good idea.

But I agree, it's ugly.

If one of the goals of QEMU is to be somewhat similar to hardware, this
should be done in the BIOS.

What happens if the BIOS provides a splash screen? Will it override the
QEMU splash screen?

Modern x86 BIOSes read the splash screen from the BIOS ROM and the
settings from NVRAM (sometimes the BIOS ROM is used for that as well by
reflashing a sector of the ROM on every boot).

A lot of things in Qemu are already not similar to hardware: virtio,
firmware configuration device, instruction timing...

Yes. The BIOS asks Qemu to display the image... or not.

A BIOS, by definition, is not modern... ;-)

What happens if you run a native BIOS/EFI/whatever for the hardware
emulated in QEMU? Some people try to do exactly that.

Agreed.

Even EFI is more modern than OpenFirmware. However, the most important
question here is how you quantify modernness ;-)

Speaking as a coreboot (really modern x86 firmware) developer, I'd like
to keep the number of workarounds for QEMU hardware quirks to a minimum.

Vbox used MMIO and port I/O before moving the splash support to the VGA device.

I think Vbox used run-length encoding for the innotek logo bitmap. Its size was
about 10 KB. If this could be used for Bochs we could put the logo into rombios32.bin
and load it from the 0xe000 segment. This should be comparable to other BIOSes.

Crap PC BIOSes have splash screens because they're horribly slow
and otherwise printing lots of irrelevant scary junk at users. The 
best BIOS 'splash' screen is one which never appears unless there 
is a boot failure, and gets control to the OS as quickly as possible.
IMHO a better goal is reducing the time until the OS / bootloader is
able to take over all management of the display.

I agree. The qemu bios init process takes almost no time.

The only reason it takes a noticeable amount of time is that we have a 
deliberate delay in there to allow the user to access the boot menu.
I'm not convinced this menu is actually very useful in practice, It's 
something that should probably be delegated to your management utility and/or 
be optional.

Yes, please. I hate this artificial delay, specifically as I have to do
a lot of short boot tests where this contributes noticeably to their
execution time. But, as usual, it didn't hurt enough to make me hack a
patch yet. I'm willing to do this if we can agree on how it should be done.

Sounds good to me. Qemu bits are already done, but now I'm stuck on
setting up the bochs bios environment. Probably I'm blind, but I can't
find a proper reference, telling me against which version the qemu bios
patch is. Currently, it does not apply against bochs CVS head.

BTW, why does qemu not carry all bochs bios source? For reference, but
also to fully comply with the LGPL (pointing to the original source is
not sufficient when delivering binaries - like e.g. bios.bin...).

OK, reading the diff more carefully told me that it's release 2.3.7.
Nevertheless, it remains "unclean" /wrt LGPL terms. And it is unhandy
for development.

If this is really an issue, then I strongly suggest we fix it by moving the 
bios into its own project, and have everyone fetch it from there.

Qemu distributes binaries that have been generated from LGPLed sources
(this is at least the case for bochs, one would have to check the
situation for the other firmware images), so it has to provide the
corresponding source code according to the license terms. But if any
bochs copyright holder will ever sue a qemu maintainer on this is a
different question.

Nevertheless, we should keep in mind that anyone else who redistributes
qemu has to comply to this terms as well, thus currently has to patch
the "license bug" out of tree. At least from this perspective, it would
be nice to fix it - however this may happen in details (wasn't there
also some idea to switch to SeaBIOS due to build simplifications, or was
this only on the kvm list?).

You are not qualified to make the statement "has to".  This is a legal 
issue and depends on how the GPL is interpreted.  The FSF provides a set 
of guidelines and so does Debian.  Debian's guidelines are more 
extreme.  If you look at the FSF FAQ on this subject, the main issue is 
ensuring that the source code is always available.

Since Bochs is on SF, as long as we ensure that the version we base on 
is always available, you could certainly conclude that's enough.

But please, this is not an issue worth even discussing here.  It is only 
relevant for people distributing QEMU and it's up to those people to 
consult with their legal teams to determine whether they need to do 
anything special.

Anthony Liguori

And why complicating things downstream when it can be fixed upstream?
Because it is only a legal issue? As a redistributor of OSS who cares a
lot about such issues, you have a lot of "fun" getting things right when
upstream forgot it.

But as it looks like, there is a consensus on changing the situation
anyway. And up to now, no animal should have been harmed, too.

I don't want to mirror Bochs source code in QEMU.  That's a lot of 
commit noise, and broken version control history.  I'm setting up a git 
repo of Bochs that contains the source we use.  I'm doing this primarily 
to make it more sane for us to maintain patches against Bochs and to 
update the bios.bin without waiting for releases.  This is also what the 
FSF FAQ recommends.

It doesn't help "downstream" but it's what is most useful for us.

This would be the best solution.  How do the bochs folks feel about this?

There is the pcbios project available at http://savannah.nongnu.org/projects/pcbios
It seems fairly out of date tho. Volker, you happen to know the status?

The PCBIOS project was based on the Bochs BIOS and started by Alex Beregszaszi 
in summer 2005. He was the project admin and I was a normal project member. 
We wanted to continue the Bochs BIOS development as a separate project. A few 
weeks later I no longer had CVS write access. I had a look at the project 
page on Savannah and found 0 members! I don't know what happend there. Alex 
had no time to take care of it and some time later he disappeared. So I 
continued the Bochs BIOS development inside of the Bochs project as usual.

So I guess it comes down to: should we re-try to set up a separate BIOS
project?

This is a fairly big deal... there are by now a number of consumers of
this BIOS beyond Bochs: at least Qemu, KVM, and Coreboot all use it.  As
such, it would be highly advantageous if the core project was separate
and maintained in a DSCM (e.g. git or hg) so that a consumer who needs
to maintain their own tweaks can do so in a sane manner.

If you pick NVRAM (RTC battery data storage) for this config item,
traditional BIOS and coreboot and EFI and OFW can pick it up without
problems. Plus, it is the traditional way to store splash screen settings.

Show the boot menu only on case no "-boot whatever" cmd line option is
present?

cheers,

I would say only when there is -bootmenu as Gleb suggested. I'm half
done with this approach already.

I agree - if you've not got an easy way to switch boot devices already,
then that's a bug in the management app being used. So a way to turn off
this BIOS boot menu would be benefical.

I also think the BIOS should either fully handle the splash screen, or
bochs/qemu should fully handle it.  I don't think it makes sense to
put part of the code in the bios and part in the emulator.

rombios.c is LGPL. Can we mix it with GPLv2/CDDL code without any downsides?

Good question. But the GPLv2 code is not in rombios.c (but in logo.h,
logo.c) and moreover VirtualBox uses the same rombios.c with their GPLv2
logo.[ch]... perhaps we can ask Sun lawyers ;-) ?
I'm the author of all the code added to rombios.c to manage splash
screen and I agree to put this under LGPL. For the logo.[ch], I keep
only approximately 20% of original VirtualBox code (data structure, to
set vga mode, to clear screen and some name), if needed I can rewrite
this to put logo.[ch] under LGPL.

Laurent
