AGNIX

[http://agnix.sourceforge.net Agnix] is an educational Operating system operating system kernel.

Agnix is an Open source project, which has been founded to provide an educational, network operating system kernel. Agnix is an extended kernel, written in pure C code. It is an ideal starting point to learn about operating system kernel architecture. In addition Agnix is a very fast and small kernel and it is suggested that it be used in Embedded_system and everywhere a fast, small and stable operating system kernel is needed.

The main goal of the project is to provide an educational, network Operating system operating system kernel which will be fully compatible with the Linux Kernel in the system call layer. The compatibility with Linux kernel is very important, because Agnix must be able to run programs compiled for Linux. This is the basis of the Agnix kernel project.

Agnix supports:

Memory: 32-bit protected mode, support for paging

Virtual memory: supports memory allocation algorithms (binary and buddy)

Task management: multithread, hardware switched tasks, round-robin scheduler

Synchronization: spinlocks and semaphores

Interrupts: interrupts serviced in fastirq kernel thread

Timers: RT timers, 100Hz system clock

Network: support for Ethernet, Address Resolution Protocol and Internet Protocol protocols

Driver interface: driver interface named ADI (Agnix Driver Interface)

Drivers: PIT, 8259, RTC, Direct memory access, Peripheral Component Interconnect, support for RTL-8029(AS) network card

Power management: support for APM

Support for busses: full support for PCI bus, PCI devices and PCI IRQs

Terminals: support for switched terminal

Data structures: hashing with open addressing, lists, queues
