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.
