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, support of popular network protocols and filesystems - all this set of features makes KolibriOS a perspective embedded OS.

"Kolibri-A" branch-project has been started in July 2010 as an attempt to resolve numerous problems related.

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

  • convenient and very powerful exokernel API functions;
  • memory-mapped Extended PCIe configuration space and Root Complex registers accessible to userspace applications;
  • user software can request access to device-specific PCI BAR regions;
  • static system buffer (8Мb) dedicated for DMA operations;
  • burst-DMA mode (PCI) and "long" PCI-express packets support;
  • an RT-optimized memory manager;
  • handling MSI interrupts with full access to APIC-space;
  • direct power control (ACPI bypass);
  • faster 32bpp graphics;
  • experimental non-scalable vector fonts (smaller and faster than standard vector and bitmap fonts);
  • optional ROM-bootloader for diskless systems);
  • extended API with faster system calls.
