Kdbus Will Likely Be Merged Into The Kernel This Year

Lennart Poettering has offered an in-depth look at the kdbus IPC system that's an implementation of D-Bus logic into the Linux kernel. Kdbus has been a work-in-progress for a while and is now finally becoming a reality.

One of the few remaining FOSDEM presentations not already covered on Phoronix since the event in Brussels at the start of February was Lennart Poettering's "Anatomy of kdbus" talk. In there he provides a very extensive look at kdbus, a project that's been ongoing since 2010 while last December it finally hit the milestone of kdbus and systemd working to make a booting Fedora system.

All of the code for kdbus is living within its own Git repository right now and also there's code within the systemd Git while a compile-time switch must be activated now within systemd. Developers are hoping kdbus will be reviewed and merged into the upstream Linux kernel this year. Lennart shared a couple of kdbus features out on the horizon include sandboxing support, yielding CPU time to destination, priority inheritance, and priority queues.

Those having an interest in kdbus can checkout Lennart's PDF slides and OGV video.
