This is a sharp technical demo with a real compiler idea behind it. The challenge is setting expectations fast: the novelty is verifier friendly program transformation, while DOOM is mainly proof that the approach can carry very large logic.

BPF Capsule is a project that compiles and runs complex C, C++, or no_std Rust programs inside the Linux kernel via eBPF, overcoming the kernel verifier's strict constraints. It transforms traditional programs to a form acceptable by the stock Linux eBPF verifier and JIT, enabling advanced logic such as running a complete DOOM game tick in kernel space. The system supports multiple target profiles from Linux 5.15 onward and works on architectures like x86-64 and arm64.
