2026-02-14video/logo: don't select LOGO_LINUX_MONO and LOGO_LINUX_VGA16 by defaultVincent Mailhol
Nowadays, nearly all systems have a color depth of eight or more and are thus able to display the clut224 logo. This means that the monochrome and vga16 logos will never be displayed on an average machine and are thus just a waste of bytes. Set CONFIG_LOGO_LINUX_MONO and CONFIG_LOGO_LINUX_VGA16 configuration symbols to no by default. Signed-off-by: Vincent Mailhol <mailhol@kernel.org> Signed-off-by: Helge Deller <deller@gmx.de>
2026-02-14video/logo: move logo selection logic to KconfigVincent Mailhol
Now that the path to the logo file can be directly entered in Kbuild, there is no more need to handle all the logo file selection in the Makefile and the C files. The only exception is the logo_spe_clut224 which is only used by the Cell processor (found for example in the Playstation 3) [1]. This extra logo uses its own different image which shows up on a separate line just below the normal logo. Because the extra logo uses a different image, it can not be factorized under the custom logo logic. Move all the logo file selection logic to Kbuild (except from the logo_spe_clut224.ppm), this done, clean-up the C code to only leave one entry for each logo type (monochrome, 16-colors and 224-colors).

2026-02-14video/logo: remove logo_mac_clut224Vincent Mailhol
The logo_mac_clut224 depends on the runtime value MACH_IS_MAC being true to be displayed. This makes that logo a one-of-a-kind, as it is the only one whose selection can not be decided at compile time. This dynamic logo selection logic conflicts with our upcoming plans to simplify the logo selection code. Considering that the logo_mac_clut224 is only used by the Macintosh 68k, a machine whose sales ended some thirty years ago and which thus represents a very small user base, it is preferable to resolve the conflict in favour of code simplicity. Remove the logo_mac_clut224 so that the logo selection can be statically determined at compile time. The users who wish to continue using that logo can still download it from [1] and add: CONFIG_LOGO_LINUX_CLUT224=y CONFIG_LOGO_LINUX_CLUT224_FILE="/path/to/logo_mac_clut224.ppm" to their configuration file to restore it.

2026-02-14video/logo: allow custom logoVincent Mailhol
Some people like to replace the default Tux boot logo by an image of their own. There exist a few tutorials here [1] and there [2]. But this requires modifying the source tree which is a bit cumbersome. Add a string entry in Kbuild for each of the logo categories (monochrome, 16-colors, 224-colors). The string entry takes a path to a .pbm or .ppm image allowing the user to more easily provide a custom logo without having to modify the sources. Add an help entry with a short hint on how to convert images to the portable pixmap file format. Update the Makefile accordingly. When converted to .c file, the logo will have one of these fixed file name: - logo_linux_mono.c - logo_linux_vga16.c - logo_linux_clut224.c: depending on the image type and this regardless of the name of the .pgm/.ppm source filename. This will allow for further simplifications in an upcoming change.

2024-06-24drm/panic: Add support for drawing a monochrome graphical logoGeert Uytterhoeven
Re-use the existing support for boot-up logos to draw a monochrome graphical logo in the DRM panic handler. When no suitable graphical logo is available, the code falls back to the ASCII art penguin logo. Note that all graphical boot-up logos are freed during late kernel initialization, hence a copy must be made for later use.

2023-07-28video: logo: LOGO should depend on FB_CORE i.s.o. FBGeert Uytterhoeven
If CONFIG_FB_CORE=y and CONFIG_FB=n, the frame buffer bootup logos can no longer be enabled. Fix this by making CONFIG_LOGO depend on CONFIG_FB_CORE instead of CONFIG_FB, as there is no good reason for the logo code to depend on the presence of real frame buffer device drivers.

This patch is for supporting Epson s1d13xxx framebuffer device for m32r. # Sorry, a little bigger. The Epson s1d13806 is already supported by 2.6.12 kernel, and its driver is placed as drivers/video/s1d13xxxfb.c. For the m32r, a header file include/asm-m32r/s1d13806.h was prepared for several m32r target platforms. It was originally generated by an Epson tool S1D13806CFG.EXE, and modified manually for the m32r platforms.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
