OSNews, Generic OSes The just released version 13.02 of the Genode OS Framework comes with major improvements of the underlying kernels. Using the NOVA kernel, the framework can be used to build custom operating systems for IOMMU-enabled machines while also leveraging hardware virtualization. Using Genode's custom kernel or the Fiasco.OC kernel, the new version targets ARM Cortex-A15-based systems such as the Exynos 5250 SoC.

About the 'low latency output': I seem to remember similar design in CoreAudio and/or PulseAudio (can't remember), did you use code from these project or did you invent your own way?

We haven't used existing code for the new audio interface. Low-level interfaces like this one are tightly coupled to the Genode API. Reusing existing work would have meant to create a glue layer between the existing code (that is typically expecting a POSIX-like environment, using mmap, Unix-domain sockets etc.) and the Genode API. I am afraid that this glue layer alone would have exceeded our custom implementation in terms of code complexity.

That said, nothing is set in stone. If we see, down the road, that adopting an existing solution would have been a better choice, we can still revise our decision. To come to the right judgement, we need to gather experience with the new interface first.
