# Open Sound System for NetBSD

This page shows the progress of the porting of OSSv4 to NetBSD.

## Update

It's not known if anyone is continuing to work on a native port of OSSv4, but this page is kept for archival purposes.

NetBSD 10 should have greater compatibility with OSSv4 via the userspace translation layer [ossaudio(3)](///man.netbsd.org/ossaudio.3), and the native audio system [audio(4)](man.netbsd.org/audio.4) is still preferred.

## Version

The current version is v4.2 (hg-889)

## Status

* DMA: ported (not complete)
* PCI config access: complete
* PCI mapping: ported to bus_space
* INB/OUTB: incomplete (should use [[!template  id=man name="bus_space" section="9"]])
* module support: WIP
* Locking: ported to [[!template  id=man name="mutex" section="9"]]
* MALLOC: ported to [[!template  id=man name="kmem" section="9"]]
* getid: ported to [[!template  id=man name="kauth" section="9"]]
* pkg: incomplete
* compat_audio: not yet
