On of the few things where getting Doom to run on it wouldn’t be that cool. But I love the post, except for the part where you reminded me I was old by acting like no one remembers that thing.
But… there was a commercial port of Doom to the Jaguar.

Anytime! As for 80 columns... I'd probably need to choose a different (Narrower) font. With a bit smaller font I reckon it should be feasible to have it (Since current one has 8x8 glyphs).
Can the Jaguar push a higher horizontal resolution? Does it use graphics hardware similar to the Atari ST family?

We used to use the blitter for that and then there was a memory location to write to to initiate execution of what was uploaded. The Jaguar developer docs are available online if you haven't seen them. Once the GPU or the DSP was running. You could then chain overlays together by running to a location in the GPU itself from which you called the blitter to upload the next segment and then you could just jump to its fi…
Ah yes, I'm more worried about the actual limits of what the combination of Linux + the initramfs can let us do (Memory wise, mostly). In theory it should be feasible but I'm not too sure how you'd "adapt" the way of doing things within Linux; the environment is very limited and I can't think of a way to cleanly make the Tom more "accessible" (While again, Tom is already executing the object lists to drive the Linux…

Completely different. The ST and TT used bitplanes whereas the Jag is chunky, and can support both YUV and RGB colourspaces. 640x200 is possible at least https://youtu.be/XI3Pvx5Yh1U?si=2bp93CeNYPTGZZic

Hi! Thanks for all your work honestly, I saw the patches and most (If not all...) were necessary to boot the kernel. As for the mainline stuff: Sure! May I reach out to see how I can help?
I followed you on github. I think you should be able to see my email address? If not the one on the 68000 fix commits in the kernel works :)
This is a deep dive on what is necessary to get Linux on the 68000-based Atari Jaguar. No specialized hardware/flash carts. All runs within the original hardware vision (2 megabytes of RAM) and gets to a Busybox shell. Linux repository with the changes: https://github.com/cakehonolulu/linux_jag
Might be fun to run this as a barebones router.

I've been slowly working on getting fuzix working on my amiga 1200. It boots the kernel I just don't have a file system for it yet. Though my 1200 has ~10MB RAM.
Do you only have a RAM expansion? If you have an MMU normal m68k linux will work for you. I have an a4000 running linux with an nvidia gpu ;) The drivers for the amiga filesystem etc all still work. If you have the stock 020 we (me and the other people messing with this stuff) can make that work. the 68000 support needs one tiny thing, fixing the stack frame differences between the 000 and the 010+, and it'll boot on…
For the moment I have a floppy disk that loads my network card drivers and then copies the kernel over the network into ram. That makes debugging things way easier than having to burn a floppy with every code change.
