Heh. Those are cool. Don't remove them. The Windoze people always look
jealous at the beer tux... :-)

[PATCH] Penguin logos

[Geert Uytterhoeven]

This patch fixes some issues with the frame buffer device penguin logo code.

Bug list:
  - The colors for the 16 color logo are wrong. We used a hack to give the logo
    its own color palette, but this no longer works as a side effect of a
    console color map bug being fixed a while ago. The solution is to replace
    the logo with a new one that uses the standard VGA console palette.
  - There are still some politically-incorrect (PI) logos of a penguin holding
    a glass of beer or wine (or perhaps even worse? :-).

Changes:
 1. Update the frame buffer console code to no longer change the palette when
    displaying the 16 color logo. Remove the tricks to load the logo palette
    in unused palette entries on displays with >= 32 colors.
 2. Replace the PI 16 color Penguin-with-beer logo by a new one, derived from
    the 224 color logo.
 3. Remove a superfluous include from drivers/char/console.c. The logo code was
    moved to drivers/video/fbcon.c a long time ago.
 4. Replace the PI black & white Penguin-with-beer logo by a new one, derived
    from the PostScript version on Larry Ewing's webpage.
 5. Remove drivers/sgi/char/linux_logo.h (containing a PI 224 color
    Penguin-with-beer logo) since it's no longer used.
 6. Remove the PI black & white Penguin-with-wine logo used on SPARC and
    SPARC64. Use the generic logo instead.
 7. Move linux_logo_* prototypes to <linux/linux_logo.h>.
 8. Simplify the logo selection logic in arch-specific <asm-xxx/linux_logo.h>.
    If you want to have an arch-specific logo, #define ARCH_LINUX_LOGO* and
    declare your data (if INCLUDE_LINUX_LOGO_DATA is defined).

Changes 1, 2 and 3 are already present in Alan's tree.
Change 5 is already present in the Linux/MIPS CVS tree.

Patches (for both 2.4.3-pre3 and 2.4.2-ac14) can be downloaded from:

    http://home.tvd.be/cr26864/Linux/fbdev/logo.html

This page also shows the old and new logos, and includes a tool to extract
logos in PNM format from the kernel sources (in case you don't trust me :-).

There's still some aliasing outlines on a bunch of them and I'm a bit
puzzled why there's an SGI logo on the MIPS penguin but not on the SGI
penguin.

Ideally, it'd be preferable to have .pnms in the source and a quick prog
in tools/ to build the include files as part of the makefile. Source
should be editable.

While I'm at it, may I suggest trading the gray background for black with
the penguin surrounded by a halo effect? It enhances his already, erm,
Buddha-esque appearance, to say nothing of "holy penguin pee".

Good idea, but the feet don't look too good. Either dither a bit,
or pick a single color for the feet. Maybe a checkerboard-dither
would get close to the right color without looking grainy.

Those also just look bad. The drink sort of floats above the penguin's
foot. It really looks like it was just pasted onto the image.

The arch-specific logos look bad in general, and the swirly gray
background isn't so great either. Why not use the original image?

I used to have only 256 colors on my display. I upgraded because
there still isn't a global system palette. I'd have been happy
enough with 256 colors allocated in a sane way, for kernel & X:

1. the 16 VGA colors and extra 4 Windows colors (so Wine can work)
2. the 216 Netscape colors
3. gray: 0x00, 0x11, 0x22... 0xff, plus both 0x7f and 0x80
4. everything else reserved for future global allocation

The current situation is way too painful to use.

I agree fully about the swirly gray - it's just looks ugly chlidish,
dilletantic
and very tasteless... plain color or some gui alike border would look
much better.

Re: [PATCH] Penguin logos

[Geert Uytterhoeven]

Finally I found some time to incorporate the very nice logos contributed by
Simon Budig. Thank you Simon!

Patches (for both 2.4.5-pre1 and 2.4.4-ac4) can be downloaded from:

    http://home.tvd.be/cr26864/Linux/fbdev/logo.html

This page also shows the curent, old and new logos, and includes a tool to
extract logos in PNM format from the kernel sources (in case you don't trust me
:-) and a (NEW!) tool to convert logos in PNM format to C source suitable for
inclusion in the kernel.

I hope these are OK for all of you, so we can finally have politically correct
and good looking boot logos!

Changelog:

  - 2001/05/03:

      o Use the logos from Simon Budig.
      o Add pnmtologo.
      o Rename ARCH_LINUX_LOGO to __HAVE_ARCH_LINUX_LOGO*.
