The goal is to try and avoid context-switch overheads incurred by the current D-Bus architecture, in which all messages are routed via the dbus-daemon, a process running in user-space. The idea is to push the message routing into the kernel by use of a new address family, and avoid two context switches per message (one is, of course, unavoidable - the message does actually need to arrive at its destination!). This should offer a significant speedup.

So, here's a start at making a list of useful notes on how to loosen up your software's lips a bit...

I needed to build D-Bus packages that could be easily put back to how they were in case stuff broke whilst I was testing, so I used Debian's source package system to get the source, build, and repackage it. I could then upload the packages to the virtual machine I am using for testing things and install them with Ian Molton home:projects:collabora Wed, 06 Jan 2010 16:38:29 +0000
