- Multi-kernel architecture proposed for Linux kernel, allowing multiple independent kernel instances on a single machine.
- Each kernel runs on dedicated CPU cores while sharing hardware resources.
- Potential use-cases include real-time (RT) kernels on select CPU cores.
- Code open-sourced by Multikernel Technologies Inc, with a 'community first' approach.
- RFC patch series posted on Linux kernel mailing list for feedback.
- Key benefits: improved fault isolation, enhanced security, better resource utilization, zero-down kernel updates.
- Leverages kexec infrastructure for loading and managing multiple kernel images.
- Inter-kernel communication via dedicated IPI framework.
- Some skepticism exists about advancing beyond proof-of-concept due to complexities.
