Metta OS is a multi-tasking operating system with a 32-bit modular x86 exokernel and vertically integrated userspace. The project is maintained by single developer with occasional contributions from third parties.

Kernel

Metta employs a 32-bit kernel which only provides MMU hardware access, interrupt processing stubs and a single synchronization primitive. The rest of the kernel runs in userspace as a privileged domain.

The vertical integration builds upon interfaces and components, composed together using resolution and binding services. This allows to securely colocate speed-critical components without any extra context switching. Synchronization primitives all build upon event primitive supported by the kernel.
