Lean, 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. ...
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 th...
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...
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.
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.
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.
