Biscuit is a research operating system kernel written in Go for x86-64 CPUs, implementing a monolithic POSIX-subset kernel with garbage collection. It was built by MIT PDOS to study the performance trade-offs of using a high-level, garbage-collected language for kernel implementation.
Use cases
- study garbage collection overhead in an OS kernel
- learn how a monolithic kernel is implemented in Go
- research high-level language kernels for systems courses
- experiment with a journaled file system and TCP/IP stack in QEMU
- explore kernel threads, virtual memory, and drivers in a small codebase
When to choose
- you are doing OS research on garbage-collected kernels
- you want a readable, small kernel codebase for teaching or study
- you need a POSIX-subset kernel that runs in QEMU for experiments
When to avoid
- you need a production operating system
- you require full POSIX compliance or broad hardware support
- you want an actively developed kernel with regular releases
