[patch 0/4] Cell SPE logos

[patch 0/4] Cell SPE logos

[Geert Uytterhoeven]

The Cell Broadband Engine contains a 64-bit PowerPC core with 2 hardware
threads (called PPEs) and 8 Synergistic Processing Engines (called SPEs).
When booting Linux, 2 penguins logos are shown on the graphical console by
the standard frame buffer console logo code.

To emphasize the existence of the SPEs (which can be used under Linux), we
added a second row of (smaller) helper penguin logos, one for each SPE.

A sample screenshot can be found at
http://www.kernel.org/pub/linux/kernel/people/geoff/cell/debian-penguin-shot.png
(or on the ps3linux T-shirts we wore at OLS :-)

  [1] fbdev: extract fb_show_logo_line()
  [2] fbdev: Add fb_append_extra_logo()
  [3] fbdev: SPE helper penguin logo
  [4] Cell: Draw SPE helper penguin logos

Thanks for applying!

Does this mean I'll get penguins on my PS3 now?

This one does give additional code and data to all fbdev users while only
being useful to cell machines.  Should we fix that?

I queued #4 up along with the fbdev patches, even though it isn't really an
fbdev patch.

I can protect it by #ifdef CONFIG_PPC_CELL (as long as there are no other
users). Would that be OK?

umm, your call.  If that makes sense, sure.

I just don't like putting platform-specific checks in common code.

Perhaps I better add CONFIG_FB_LOGO_EXTRA and make it depend on
CONFIG_PPC_CELL?

I hate depends when it's not a dependency... the logo extra code doesn't
-depend- technically on cell (it doesn't call cell only stuff). However,
cell wants it enabled, thus I'd rather use either the "default y if
PP_CELL" construct or select it from the cell option.

[patch 0/4] Cell SPE logos

[Geert Uytterhoeven]

[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain, Size: 1616 bytes --]

The Cell Broadband Engine contains a 64-bit PowerPC core with 2 hardware
threads (called PPEs) and 8 Synergistic Processing Engines (called SPEs).
When booting Linux, 2 penguins logos are shown on the graphical console by
the standard frame buffer console logo code.

To emphasize the existence of the SPEs (which can be used under Linux), we
added a second row of (smaller) helper penguin logos, one for each SPE.

A sample screenshot can be found at
http://www.kernel.org/pub/linux/kernel/people/geoff/cell/debian-penguin-shot.png
(or on the ps3linux T-shirts we wore at OLS :-)

Summaries:
  [1] fbdev: extract fb_show_logo_line()
  [2] fbdev: Add fb_append_extra_logo()
  [3] fbdev: SPE helper penguin logo
  [4] Cell: Draw SPE helper penguin logos

Compared to the previous submission, patches 2 and 4 were modified (cfr. the
changelogs in those patches).

Thanks for applying!

Let spu_management_ops.enumerate_spus() return the number of found SPEs
and use that information to draw some little helper penguin logos.

fbdev: make fb_append_extra_logo() depend on fb=y

[Arnd Bergmann]

We can't show the extra logo from boot code if FB is built as
a module. Make the FB_LOGO_EXTRA depend on FB=y.

Reported by Al Viro. I don't know how this ended up in the final
patch, as I'm pretty sure we talked about this scenario before
and had a solution...

It happened because introducing CONFIG_FB_LOGO_EXTRA was done in the last
iteration (before the code was protected by #ifdef CONFIG_FB), and I got
bitten by the weird Kconfig logic again.

Re: [patch 0/4] Cell SPE logos

Does this belong in kernel?

It is kernel boot log, not random advertising place. Various splash
projects can get you any graphics you want...
