Project: High-Performance Cooperative Coroutine Runtime and Scheduler
Synthesize mmap guard-paged stacks, x86-64 assembly context pivots, epoll I/O multiplexing, timerfd sleep queues, and CSP channels into an integrated coroutine runtime in C.
By the end you can
- Integrate mmap virtual stack allocation, mprotect guard pages, and recycled stack pooling
- Wire the 14-instruction x86-64 assembly context switch with exit trampolines and lifecycle tracking
- Unify asynchronous socket polling and timerfd events inside a central non-blocking scheduler loop
- Implement user-space cooperative synchronization via fiber mutexes and bounded CSP channels
Builds on Multi-Threaded M:N Schedulers: Work-Stealing Queues and Thread-Local Workers.
01 · A question first
How do modern runtimes like Go and Tokio schedule hundreds of thousands of concurrent tasks with sub-millisecond latencies and microsecond memory overhead? Let us integrate stack mechanics, assembly pivots, epoll event loops, and CSP channels into a complete production coroutine runtime.
Make a guess before you read on.
