Fiasco.OC belongs to the L4 microkernel family. A microkernel + provides a bare minimum of services to the applications + running on top of it, unlike traditional kernels that + incorporate a complex code like IP stacks and device drivers. + This allows to dramatically decrease the amount of code + running in the privileged mode of the CPU, achieving higher + security while still providing an acceptable level of + performance.

+ +

Running an operating system kernel on top of the microkernel + allows to leverage any software that was developed for that + operating system. The OS kernel runs in user-mode side-by-side + with other microkernel applications such as real-time + components. Multiple OSes, each with their userland + applications, may be even run in parallel, thus allowing to + build the products where processing of corporate data is + strictly separated from the processing of private data.

+ +

The project aims to create a port of &os; to Fiasco.OC + microkernel, which is a high performance L4 microkernel + developed by TU Dresden. The existing ports of OpenBSD and + Linux are used as a reference. This will allow to use the + unique &os; features like ZFS in L4-based projects.

+ + + + Finish opensourcing the port of L4OpenBSD/amd64 made by + genua mbh. This is a work in progress. + + Publish the sources of L4&os; port that is largely based + on the L4OpenBSD code. + + Improve the port, the first task being adopting the + pmap(9) module to work with L4 microkernel memory allocation + services. + +
