Kernel Design microkernel vs. multikernel

Why was the choice of the kernel implementation fallen on the microkernel and not on a more modern design like a multikernel?

Does Multikernel mean a combination of monolithik kernal and microkernal?

I’m talking about a multikernel as used in the “Barrelfish OS”. It’s kind of an alternative Idea on how we deal with multicore systems.
For your Interest: http://www.barrelfish.org/publications/TN-000-Overview.pdf, Chapter 1.1 and 1.2

So why didn’t we use a Multikernel then?

Yeah, that’s exactly my question

So you might want to meet stratact from the chat forum he explained why multikernel is not a good approach.

https://chat.redox-os.org

I didn’t quite understand what he said its too techinical, but he did suggest what would be the best is to use a multi microkernel.

I can’t get into the chat for some reason. Anyhow, I am currently exploring base for Barrelfish type implementation. I would think you could just take whatever parts from Redox you like as a base and then build the multi kernel. That is my hope at least :slight_smile: any architectural reasons to my knowledge for design choices are compatibility and implementation, preference, skill specific. If you aren’t the one building it then you don’t get to make those design decisions and probably won’t understand why.
