That all sounds very interesting, but it goes far beyond the scope of my current concern with microkernels. At the moment, I am satisfied with extending a well-documented approach such as Minix with sel4 (or other candidates) in such a way

That's interesting, thanks for the explanation and the references. Of course I agree with Parna's modularization principles, and having spent a lot of time with different versions of the Oberon and Active Object system I think tha

What's the core concept compared to other kernels?

Thanks for the hint. vocho/openqnx has about 200 forks, and many seem to have been maintained. The original vocho/openqnx repository is the result of the MONARTIS (MONitoring Application for Real-Time Industrial Systems) project c

The HongMeng kernel, performance wise, seems indeed to be in the same ballpark as sel4 or QNX, but it doesn't seem that it will be open-sourced.

Are you a lawyer? USA law recognizes promissory estoppel, European laws provide protection by the good faith principle. The press release explicitly states that developers would have access to download "direct from the dev team's

It clearly states that the company made the referenced source code version available for free.

Nice article, interesting read. The Neutrino 6.4 version, which was made accessible as "openQNX" to the public, can still be downloaded from e.g. https://github.com/vocho/openqnx . Here is an AI generated docu

Thanks for the clarifications. May I ask what made you use Zig instead of e.g. Rust or C++ (or even Ada/SPARK)? I assume Go would be too undeterministic for real-time applications?

Lightpanda looks interesting, thanks for the hint. According to public sources, behind the development is a company of 2-10 employees (like Bun). The engine uses parts of the Netsurf browser (written in C) and the V8 engine (written in C++)

by Rochus 1y ago
Thanks for the hint. According to public sources, Bun's runtime infrastructure and bindings are written in Zig, but it uses Apple's JavaScriptCore engine written in C++ (i.e. Zig is essentially used in a thin wrapper layer around

Are there other notable commercial companies/projects than Tiger Beetle relying on Zig? According to public information, Tiger Beetle are about eight employees with a single customer, isn't it?

by Rochus 1y ago
Is this really the first Zig book since the development startet in 2016? Maybe the language and library is just too volatile for a book.

The Go compiler is also pretty fast.

In QNX, the (async) IPC is integrated with the scheduler, which is apparently responsible for the performance (still researching). So I was wondering if you chose a similar architecture. My email is "me at rochus-keller dot ch". T

by Rochus 1y ago
Amazing, thanks. Is it possible to just have a look at the source code somewhere, e.g. codeberg or gitlab? I'm especially interested in the microkernel IPC.
565.
by Rochus 1y ago
That's interesting. Did you have access to the QNX sources at the time and were able to study the QNX kernel and why it had a much better performance than Minix? Given your reference to DJGPP, am I right to assume that you have written
