[Buildroot] psplash and systemd

[Tom Deblauwe]

Hello,

I am using psplash in my initramfs and it shows up a graphical
bootscreen, but then the regular bootprocess starts and there I would
like to continue showing the splash screen. I am using the 6d3336a
commit of master buildroot. So I would like to use systemd. What is the
best solution for this?

Best regards,
Tom,

Please find attached a patch that installs two new services for using psplash
with systemd. These are inspired by the ones from Plymouth
(http://cgit.freedesktop.org/plymouth/tree/systemd-units/):

- psplash-start.service for starting psplash.
- psplash-quit.service for killing psplash when reaching multi-user.target.

I tested them on QEMU machines:

- on QEMU/x86, the boot is very quick, so the boot screen is not displayed for
  a long time.
- on QEMU/ARM, the boot takes longer, so the screen can be seen.

Besides, no progress messages are printed when booting (I have not found how
to do it yet).

Thought these configurations do not use an initramfs followed by a
switch-root, these service files should provide you a good start.

Best regards,
ELB

Hello Eric,

Thanks for this patch it helps me indeed and works. However I am looking
into starting it even earlier in the boot process so I'll let something
know if I find it.

Thanks,
Best regards,

Can you submit this patch properly, i.e with git send-email, so that it
can be applied?

I'll mark it as "Changes requested" in patchwork in the mean time,
awaiting for your new posting.

Thanks a lot, having psplash integration looks really useful!

Thanks for your patch. To get the gdk-pixbuf-csource tool in Buildroot,
you simply need to make your package depend on host-gdk-pixbuf.

It would be good to take the systemd psplash patch and your patch,
create proper commit logs, and submit them using git send-email. See
http://buildroot.org/downloads/manual/manual.html#submitting-patches
for details. Your contribution would be much appreciated!

Thanks!

I posted a proper patch. As for adding progress report from systemd to
psplash, this would require a patch to src/core/manager.c in systemd to write
to psplash socket.

BTW, maybe we should provide a patch to set the default image with the famous
Buildroot hard hat, to replace the "POKY" theme...

Best regards,
ELB

Ok, found at http://patchwork.ozlabs.org/patch/358888/.

Indeed, that would be good to have.

Thanks!
