[PATCH 0/7] RFC: Cell SPE logos

From: Geert Uytterhoeven <hidden>
Date: 2007-01-31 12:28:04 

	Hi,

I would like to hear your opinions about the patchset below (updated version
compared to yesterday, lkml added to the CC list).

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.
I attached a PNG version of the helper penguin logo for reference.

Summaries:
[PATCH 1/7] fbdev: Avoid vertical overflow when making space for the logo
[PATCH 2/7] fbdev: fb_do_show_logo() updates
[PATCH 3/7] fbdev: extract fb_show_logo_line()
[PATCH 4/7] fbdev: move logo externs to header file
[PATCH 5/7] fbdev: Add fb_append_extra_logo()
[PATCH 6/7] fbdev: SPE helper penguin logo
[PATCH 7/7] Cell: Draw SPE helper penguin logos

Thanks for your comments!

Gr{oetje,eeting}s,

[PATCH 4/7] fbdev: move logo externs to header file

From: Geert Uytterhoeven <hidden>
Date: 2007-01-31 12:44:43 

Move the external declarations for the various linux logo structures to
<linux/linux_logo.h>. As a consequence, I had to remove the `const', as `const'
is incompatible with `__initdata'.

Hi1

I would like to hear your opinions about the patchset below (updated version
compared to yesterday, lkml added to the CC list).
Can you just blast these pictures from userspace? There's really no
excuse to advertise SPEs from kernel....

What's next, I have powerful Intel graphics chipset in here, perhaps
it is as powerful as SPE, shall I start adding little pictures for its
pipelines?

Everything drawn on a frame buffer (penguin logos, text console, ...) can
indeed be done from userspace.

What's next, I have powerful Intel graphics chipset in here, perhaps
it is as powerful as SPE, shall I start adding little pictures for its
pipelines?
Do you have in-kernel support for running generic code on those pipelines?

By the same token, there is no excuse to have the logo code at all in
the kernel in the first place... it's cool though :-) And it's a config
option, so you don't have to have it....

True. Of course we would need a userland interface to splash a logo. I 
found the logo to be useful to know if the graphics device is alive and 
working properly.

I would like to hear your opinions about the patchset below (updated version
compared to yesterday, lkml added to the CC list).

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.
I attached a PNG version of the helper penguin logo for reference.

Summaries:
[PATCH 1/7] fbdev: Avoid vertical overflow when making space for the logo
[PATCH 2/7] fbdev: fb_do_show_logo() updates
[PATCH 3/7] fbdev: extract fb_show_logo_line()
[PATCH 4/7] fbdev: move logo externs to header file
[PATCH 5/7] fbdev: Add fb_append_extra_logo()
[PATCH 6/7] fbdev: SPE helper penguin logo
[PATCH 7/7] Cell: Draw SPE helper penguin logos

Thanks for your comments!
    Now that their are patches for the logo I would like to see a few more 
improvements that I haven't gotten too. I really like to see the logo 
drawn outside of fbcon. This way for embedded platforms without fbcon we 
could have the logo to know if the graphics device worked.

I believe the old logo code was originally created for compatibility
with Solaris? :-).

The helper penguins overlap with the main penguins when using console rotation

---

Correct the image offsets when rotating the logo. Before image->dx and
image->dy were always zero, so nobody ever noticed.

By modifying scripts/pnmtologo.c to add `const' to the declaration of the
linux_logo structs, I could keep the const.

However, this introduced a new conflict w.r.t. to `const' and `__initdata':
  - gcc 3.4.6 20060404 (Red Hat 3.4.6-3) for ia32 needs xxx_data[] and
    xxx_clut[] to be const too, else it complains about a section type conflict
  - ppu-gcc 4.1.0 20060304 (Red Hat 4.1.0-3) for ppc64 needs xxx_data[] and
    xxx_clut[] to be non-const, else it complains about a section type conflict

Anyone with a suggestion how to fix this? Keep everything non-const for now?
Add tests for specific compiler versions (I assume this is a gcc 3.x vs. 4.x
issue?)?

Thanks in advance!
