L4: a growing family of 2nd-generation microkernel realtime operating systems (RTOSs) that are fast, small, lean, maintainable, readable, preemptible, support hard priorities, use non-blocking synchronization for kernel objects to guarantee priority inheritance and ensure runnable high-priority processes never block waiting for lower ones. All scale well from tiny embedded systems to huge servers, and use hierarchical external pagers and guarded page tables, with fast, message-based, synchronous IPC, simply-used external paging mechanisms, security mechanism based on secure domains: tasks, clans, chiefs. Kernels try to implement only a minimal set of abstractions on which OSs can be built flexibly. L3 has system-wide persistence. All kernels are roughly compatible and many run on many platforms: ARM; MIPS; 68k, PPC; x86; L4Linux ports exist. Goals: create, prove, establish new methodology for systems that helps manage growing OS complexity and minimizes legacy dependence. [Open Source, GPL]

  • DROPS - The Dresden Realtime Operating System Project L4 and Linux based research project aiming at the support of applications with Quality of Service requirements. At TU Dresden.
  • E1 A distributed operating system based on the concepts of object replication, component model support and persistence. It consists of a L4 microkernel and a set of distributed objects acting at the user level. [Open source]
  • Fiasco Preemptible, realtime, 2nd-generation microkernel, fast, maintainable, readable, supports hard priorities, uses non-blocking synchronization for kernel objects to guarantee priority inheritance, ensure runnable high-priority processes never block waiting for lower ones; rework of L4 interface. [Open Source, GPL]
  • L4 Microkernel L4/MIPS: stable L4 for MIPS R4x00 processor, may be fastest kernel for this architecture. L4/Alpha: begun at Technical University of Dresden, SMP version released. Linux ports: L4/MIPS, L4/Alpha underway.
  • L4/Darwin: Darbat Experimental port of Darwin to L4 to study traits of large-scale microkernel-based system; has port of IOKit to L4, modified libc to communicate to Darbat Server, XNU with many machine-dependent parts highly modified. National ICT Australia.
  • L4 Microkernel Family Growing article, with links to many related topics. Wikipedia.
  • L4Ka Project L4-based microkernel systems, for embedded systems to huge servers; Pistachio kernel. L4: tiny, fast, 2nd generation microkernel using hierarchical external pagers and guarded page tables. Goals: create, prove, establish new methodology for systems that helps manage growing complexity, minimize legacy dependence.
  • Mungi Orthogonally persistent, capability-based secure SASOS using L4 2nd generation microkernel. Goals: Prove SASOSs can run on normal hardware, be as secure as normal OSs; can be as efficient as, and are faster than, normal OSs in some important uses; can be pure SASOSs with all data (even system data) in one address space and no other IPC mechanism is supported by OS. POSIX emulating. [Open Source, GPL]
  • Perseus A secure platform for applications that use digital signatures. Based on L4 and Linux. Research project at Applied Data Security Group, Ruhr-University Bochum., Germany.
  • SourceForge: L4Ka Microkernel The L4Ka microkernel is an L4 compatible kernel running on many platforms: ARM; MIPS; 68k, PPC; x86. A port of Linux atop an L4Ka microkernel exists.
  • Virtualised OS: Wombat Experimental port of Linux to run on L4/Iguana; is not intended to be standalone, best used as part of Iguana project. National ICT Australia.
