Alyssa is an absolute legend. Every time I read a banger blog post I check the author, and on multiple sites she comes up as the OP.
While Linux can’t mix page sizes between processes, it can virtualize another Arm Linux kernel with a different page size. So we run games inside a tiny virtual machine using muvm, passing through devices like the GPU and game controllers. The hardware is happy because the system is 16K, the game is happy because the virtual machine is 4K
Insane work, holy shit
It’s absolutely mental that a reverse-engineered hardware stack, with a bespoke gpu driver in Rust, achieved this kind of performance, in this amount of time. God tier skills, between all the engineers involved in the project
I liked how each of the sections ended with a different game that she’s gotten running so far. It makes the article feel like a progressively bigger flex, which, of course, it is. Awesome to see this work progressing!
