Embedded-KOS

As it was shown (see for example KolibriOS for Manufacturing control), KolibriOS can be successfully used in wide range of data acquisition and process control systems.

A compact open-source kernel, a simple and convenient minimalistic graphics subsystem, fairly developed user interface, very capable low-level system services, most popular network protocols and filesystems support - all this set of features let us possess KolibriOS as a perspective embedded OS.

In the other hand, some serious problems still must be solved to make it a true embedded-OS: [1].

As an attempt to try different solutions of those problems, "Kolibri-A" branch-project has been started in July 2010.

NB: the A letter means its code will be tied to AMD/HT architecture; particularly to a well-documented AMD chipsets NB780/SB700 and Fusion/Hudson. Other platforms might not be supported in the nearest future...

Note also that some specific features of Kolibri-A are 100% experimental: - you're warned you can use or test this branch on your own risk, and - you should realise that some of these features will never be merged to the main KolibriOS trunk.

Specific features of Kolibri-A

  • extended PCI service;
  • direct read/write transactions to/from several user-accessible memory-mapped IO regions;
  • a static system buffer (8Мb) available for non-standard device testing and user-world DMA-operations;
  • an RT-optimized memory manager;
  • burst-DMA mode (PCI) и "long" PCI-express packets support (also in the userspace!);
  • native support of Extended PCI-express configspace;
  • direct (APIC-unfriendly) power control;
  • 32bit-optimized graphics,
  • experimental non-scalable vector fonts,
  • optional ROM-bootloader,
  • fast system calls.
