Hi tech@, The size of kernel fonts in RAMDISKs has long been a problem on systems with large screen resolutions booting via EFI, as currently only the 8x16 font is built into RAMDISKs. As those systems are becoming more common, I would like to revisit the topic.
Currently, we decide which font is built into which kernel in wsfont(9), which will only add the 8x16 one when SMALL_KERNEL is defined, and larger fonts for selected architectures for !SMALL_KERNEL. There is no way to distinguish between RAMDISK and RAMDISK_CD kernels using #ifdef trickery, so with the current way we cannot add larger fonts only on RAMDISK_CD. As a reminder, we cannot add them to RAMDISK because there is no space left on the floppies, and there is no support for EFI systems on the floppies anyway. However, unless I overlooked something, this could be solved by adding option directives directly in the RAMDISK_CD kernel configuration file. This is how it would look like for amd64: Index: sys/arch/amd64/conf/RAMDISK_CD =================================================================== RCS file: /cvs/src/sys/arch/amd64/conf/RAMDISK_CD,v retrieving revision 1.190 diff -u -p -r1.190 RAMDISK_CD --- sys/arch/amd64/conf/RAMDISK_CD 27 Dec 2020 23:05:37 -0000 1.190 +++ sys/arch/amd64/conf/RAMDISK_CD 31 May 2021 09:39:24 -0000 @@ -20,6 +20,11 @@ option MSDOSFS option INET6 option CRYPTO +option FONT_SPLEEN8x16 +option FONT_SPLEEN12x24 +option FONT_SPLEEN16x32 +option FONT_SPLEEN32x64 + option RAMDISK_HOOKS option MINIROOTSIZE=7360 Does this look reasonable? If it does and if we want to go this way, I can try to build a release and check if MINIROOTSIZE must be bumped on RAMDISK_CD. Then we could do the same for i386, armv7 and arm64.
