Well, Dolphin is an emulator, so screenshots and videos are quite an obvious tool to demonstrate game emulation issues... and it's also easier to boil down most changes to "fixes X issue on Y game" for a mature project; that model doesn't map quite as well to the early stages of an OS port project, especially since most of the stuff in this first report is literally required to get anything to work at all. The one screenshot of the framebuffer with 8 penguins at the end effectively represents the result of the entire prior saga, and everything before it would be various flavours of "black screen", "kernel panic", "the serial port stops working", etc... not very interesting to show!

What kind of diagrams are you looking for? There's lots of things that could be diagrammed here, but comprehensively explaining every concept involved would turn this into an embedded systems course, diagrams or not. What I tried to do was give a brief introduction to concepts that are relevant to the issues we ran into, and have links for those who want to go deeper. If you have specific suggestions of bits that are hard to grok without diagrams though, please do let me know. It's tricky knowing what is most confusing to other folks when you've been neck-deep in this stuff for weeks.

The alternative to this long-form post is to just have a laundry list of things that work today, but I don't really know how I would get across what the challenges were without going into at least some level of details like I did here. I figure that if I'm going to do that, I might as well make it a more educational endeavour. Of course, if all you want to know is what works and what doesn't, it may not be for you... I'm open to suggestions though!

Keep in mind that a lot of the early work ends up being "how to find the right solution to problems" (and the post goes into more detail about this); the current feature support status of Linux on M1 almost hasn't changed for the past 30 days, because instead I've been re-visiting and re-working the code into a form that is upstreamable, as well as building tools and chipping away at little details. It's a lot of yak shaving, but it's all things that need to happen sooner or later. Unfortunately, it doesn't really tick boxes in a TL;DR bullet list of working hardware.
