When I boot up I see the 12x22 fonts for a while then it switches to
the tiny fonts default font about half way throught the boot process.
My goal is to have the system running with the 12x22 fonts. I do not
plan to run X. Does anyone know how why it swtiches away from my
custom fonts ?
running:
3.17.0-rc-5+ on a MacBookPro with EFI and booting the kernel
with the efi-stub from gummiboot.
built with:
Support for frame buffer devices
EFI-based Framebuffer
Support Framebuffer Console support
Select compiled-in fonts
Sparc console 12x22 font

the kernel EFI framebuffer driver is "odd", and probably can not support
your console fonts. I know mine can not, sorry.

When the machine first starts loading the kernel it swtiches from the tiny
fonts that gummiboot uses to the Sparc 12x22 fonts, then switches back.
What framebuffer driver is being used when the kernel first starts
loading? I tried disabling the EFI-based Framebuffer thinking it would
not switch, but this causes no output at all after gummiboot.
My point is, my system *does* show the fonts I want (for a second) so this
makes me think it can support this.

gummiboot "uses" the default UEFI terminal mode, it doesn't select any
specific font or size, it just uses what UEFI provides it.
Same for the UEFI console driver, I don't think there is a way to change
the fonts for it.

The "default" framebuffer. VGA perhaps? You can try to force it to be
this one but on an UEFI system, I don't think it will work.

Good luck, and let us know if you get this working, as my machines would
like to see it happen as well, but I don't know if it is possible.

It is possible! I just got it working the way I want.
I saw that the kernel messages where using the custom font (the
larger font). I put a while(1); right before the kernel called init.
The system booted and hung at the while(1); and was using the custom
fonts. I realized then this was a userspace issue.
I ran dpkg-reconfigure console-set and went through the menus and choose
the option-> 'Do not change the boot/kernel font'
now it doesn't switch back and I am able to see the cusom font sun 12x22
I was also about to select VGA from the dpkg-reconfigure menu and get
large fonts
I'm really happy about this, because now I can do more work without X,
not have to strain my eyes, and I understand my system a little better.
