Agnix
'''Agnix''' is an educational [[Operating system|operating system]] [[Kernel (computer science)|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 programming language|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|embedded systems]] 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]] [[operating system kernel|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|mulithreading]], 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|ARP]] and [[Internet Protocol|IP]] protocols.
*'''Driver interface:''' driver interface named ADI (Agnix Driver Interface).
*'''Drivers:''' [[PIT|8254]], [[8259]], [[RTC]], [[Direct memory access|DMA chips]], [[Peripheral Component Interconnect|PCI bus]], support for RTL-8029(AS) network card.
*'''Power management:''' support for [[Advanced Power Management|APM]].
*'''Support for busses:''' full support for PCI bus, PCI devices and PCI IRQs.
*'''Terminals:''' support for switched terminals.
*'''Data structures:''' hashing with open addressing, lists, queues.
