TL;DR: What linux API should be used to render a game to the screen on the RG35XXH?

I'm trying to port a solitaire game to the RG35XXH. Currently I'm using GLFW to get a window on my laptop; however GLFW doesn't support running without an X11 or Wayland server running.

I looked into EGL, which worked, kind of. It can fetch an OpenGL ES context but it has no way to display the rendered framebuffer to the screen.

Most recently I looked into KMS + DRM. I found a repository with code explaining how to interface with the DRM, and got it working on my laptop, which is nice! However on the RG35XXH (with Batocera v40) there is no /dev/dri/ folder 😦 . I can only assume that this means Batocera doesn't use DRI/DRM/KMS at the moment.

Next I might try using a frame buffer device. Running cat /dev/urandom > /dev/fb0 fills the screen with random colors; so I should be able to implement rendering with it. However I don't know if this is the correct route to go.

Now, as I understand it, SDL2 is supposed to support rendering to these types of devices. I've been avoiding SDL2 as I would prefer to distribute the program as a single executable file, and its license makes that more difficult.

Do you have some specific examples? I read half of the PDF but I don't have knowledge of case laws that would be relevant.

This headline is wrong. The DOJ is alleging that they are being anticompetitive in the Performance Smartphone market, and further that their anticompetitive behavior affects even the regular smartphone market.

The document published by the DOJ make the point that Apple has closer to 65% market share of you to by revenue, and also have a high market share amoung the teens. But I don't get this focus on whether or not Apple is a monopoly. The lawsuit alleges that Apple has a significant market share is using anticompetitive practices to stay there.

Ordered on the day after (got an out of stock on day one) and my order is showing packaged ATM.

Factorio and I just picked up a game called Outpath (similar to Forager, but in 3d! and other minor changes).

I've been playing through Sea of Stars. I've been enjoying it so far. It's music and aesthetic are fantastic.

One of the neat things is that Box64 will use libraries compiled for RISC-V of it can. Which means stuff like OpenGL will run at full speed.

I think this is unlikely to happen. Going through security is one of the big sources of useless queues at airports, which trains don't have. Trains also tend to have more doors to get, which should reduce the length of queues to get on the train.

Ember Knights has already been mentioned, but I'll go ahead and suggest Full Metal Furies.

Mixolumia.

I haven't been playing much lately, and when I do sit down to play I don't feel like putting a ton of effort into anything. Mixolumia is easy to pick up and put down.

Is that with Linux kernel specifically or the user space? I've heard that Linus tries to keep the kernel interface stable, but most userspace progtams don't share that philosophy.
