I wouldn't scale at compile time (as said, storage constrained payloads might not be happy about that). I wouldn't scale each character up on each access though (we won't hardware accelerate the scaling, and yes, that does get slow - framebuffers aren't always the fastest type of memory and that

Re: [coreboot] Hi-DPI displays and showing text information for kevin in depthcharge

I agree with most of what Patrick said, I think dynamic scaling to integer multiples may be best. Scaling the font up at compile-time seems like unnecessary bloat to the binary (although I'm not sure, how big are these fonts?). If you do want to include them at compile time, you may as well

[coreboot] Hi-DPI displays and showing text information for kevin in depthcharge

I am using upstream coreboot with top-of-tree depthcharge and vboot on kevin (Chromebook Plus from Samsung) and I've patched depthcharge[0] to display text messages instead of looking up bitmaps in the GBB/cbfs. I noticed that corebootfb is using[1] a fixed 8x16 font for showing text there. In
