I just read "Google Continues Working On "Magma" For Mesa Cross-Platform System Call Interface" on Phoronix and didn't get it. That made me realise my knowledge and understanding of these things is barely existent. I did write an MS paint clone on linux in C++ a really long time ago and the entire thing was with opengl (it looked like crap), but since then... nothing.

So my understanding is that the graphics card (or CPU if there's no graphics card), writes to a component which is connected to a screen and every cycle (every 1/60 seconds if 60Hz) the contents are sent or read by the screen. OpenGL provided a common interface to do so, but has been outdated since... a while and replaced by Vulkan. Then there are libraries either built on top of are parallel to OpenGL. Vulkan can be parallel or use OpenGL if that's the only one supported IIRC.
However, I'm not sure if OpenGL is implemented at the hardware level (on the graphics card), software level, or both.

Furthermore, I don't understand where Magma, Meta, and MESA come in.

Maybe my core understanding is wrong or just outdated. I can't tell. Can anybody eplain?
