An embeddable version of KolibriOS carefully optimized for last-generation AMD Fusion APUs.

http://websvn.kolibrios.org/listing.php?repname=Kolibri+OS&path=%2Fkernel%2Fbranches%2FKolibri-A%2Ftrunk

Main features:
- faster graphics,
- extended PCI-express services
- driverless access to MMIO, DMA and Configspace blocks
- ROM boot options
- fast non-scalable vectorized fonts
- reduced kernel size ~60kB

Main applications:
- technical vision and wideband DAq,
- new hardware development/testing,
- resource-hungry embedded systems,
- Media-aimed OS,
- experimental KolibriOS concepts testing,
- Kolibri-B project development.

So, Kolibri can run on 64bit machines. I am right Question

Yes, it surely can.

Even MS-DOS can run on 64bit machines.
am I wrong?

art_zh link you have given points on sources. Is there somewhere binary version, or better full distro Question

In this site I can download img file with 32 bit distro, but I want 64 bit Kolibri. Maybye I should compile Kolibri A kernel (link art_zh has given), and inject to image instead old 32 bit kernel.

Then you need to wait for a short while -- Kolibri64 is still under development

you asked could Kolibri run on a 64bit machine --
it surely can... in x86_32 mode Wink

A binary image is here:

ftp://ftp.kolibrios.org/users/art_zh/-A/

NB: it will only run on AMD Fusion machines, see the source!

What sort of optimizations? Llanos CPUs parts were basically the same as 45nm K10s. The only very specific thing I recall hearing is that there was a dedicated pathway bewthem the CPU and GPU to transfer blocks of data internally instead of the CPU writting to RAM for the GPU to read from it.

Apart of these architectural differences, every processor/chipset has its own specific hardware implementation: MSRs, GPIO pinouts, devices' ID and configuration space, system bus control, power control, SIO access etc.

An obvious way to resolve these platform-specific dependencies is to rely on ACPI and BIOS structures and (on the top OS level) to include unique device drivers to the OS API.

Kolibri-A does not use ACPI and minimally relies on BIOS/CoreBoot helpers. Instead, it communicates with the given hardware directly, in accordance with AMD's BKDG and other system references.

This approach dramatically reduces system latencies and code size; it found to be very useful for many embedded and hardware-development tasks...

... but (in the other hand) it will surely work on Fusion platworms only.
