BUS1: A New Kernel IPC Bus Being Made By Developers Written by Michael Larabel in systemd on 9 December 2015 at 11:30 AM EST. 17 Comments

While KDBUS has yet to be mainlined as it was sent back to the drawing board, at least some of the systemd developers are working on a new kernel bus implementation called BUS1. Latest Linux News GNOME's Epiphany Web Browser Finally A Phoronix reader pointed out to us the new bus1 project that has been unheard of until Enables WebGL + WebAudio By Default now without making any news rounds. BUS1 consists of a libbus1 library, bus1 kernel BUS1: A New IPC Bus Being module, UEFI components, and some system initialization tools. Made By Systemd Developers Google's Pixel C Android Tablet Uses The BUS1 isn't being developed by just some unknown individuals, but systemd developer David Herrmann and Nouveau Kernel Driver Kay Sievers seem to be the lead (and only) developers working on it thus far. Both developers are employed by and there is Red Hat's copyright on some of this code, making it look like it could be an official A Popular European Cable Modem Is Now project in the works. BUS1 is licensed under the LGPLv2.1. Open-Source Threaded Input Is Back To Being Worked On For The X.Org Server Ubuntu 16.04 LTS Temporarily Rebases To Linux 4.3 Recapping The Intel Graphics Changes Of Linux 4.4 R600 Gallium3D Lands Another OpenGL 4.3 Extension (Copy Image) Support For DRI1 Might Be Stripped From The X.Org Server HTC Vive VR Retail Launch Delayed Until April 2016

BUS1 is being designed to be a low-level IPC technology that will also provide a high-level interface for applications. Compared to KDBUS, BUS1 doesn't seem to be at least heavily based on D-Bus.

Those wanting to get an idea for the early, in-development interface for BUS1 can see some of the sample tests and more from the libbus1.

More details on BUS1 as they become available... Don't look for any major announcements soon as the project still appears to be very young. As I haven't seen BUS1 mentioned yet on the systemd or LKML mailing lists, no idea the official stance yet and if the developers are hoping for this to take the steam from KDBUS.
