Subject: Logo updates
Date: Sun, 23 Feb 2003 13:34:03 +0100 (MET) [thread overview]
Message-ID: <Pine.GSO.4.21.0302231333090.28532-100000@vervain.sonytel.be> (raw)
Logo updates, relative to James' latest fbdev.diff.gz.
- CONFIG_FB_LOGO got renamed to CONFIG_LOGO
- Drop CONFIG_ prefix for SGI_NEWPORT_CONSOLE in drivers/video/logo/Kconfig
- Prefix standard logo help texts with `Standard'
- Add drivers/video/logo/clut_vga16.ppm, to be used with ppmquant(1) when
creating 16-color logos
- Add comments to PNM logos
- Add missing pnmtologo to scripts/Makefile
- Add missing scripts/pnmtologo.c
- Update pnmtologo:
o Correct rounding rule when converting between different maxvals
o Suggest using pnmnoraw(1) to make binary PNMs usable
o Suggest using ppmquant(1) to reduce the number of colors, if needed
James, you also forgot to remove the old asm-*/linux_logo.h files. Please do:
bk rm include/asm-alpha/linux_logo.h
bk rm include/asm-arm/linux_logo.h
bk rm include/asm-i386/linux_logo.h
