The development of real-time capabilities integrated in the standard (aka "vanilla") Linux kernel went an important step ahead: Version 2.6.29.4-rt17 is now "Latest Stable" and as such ready for production purposes. This version contains, of course, all upgrade changes of the vanilla Linux kernel 2.6.29 including considerable performance gains. On the real-time side, a better responsiveness - especially in the context of sending and receiving signals - was achieved. More details on this new version as well as general information and installation instructions are available on the OSADL Website www.osadl.org.
In terms of release date, real-time Linux is now pretty close to vanilla Linux - the -rt tree of 2.6.29 became "Latest Stable" on the same day as vanilla 2.6.30 was released - thus, the -rt real-time tree is only one release number behind! And the distance between vanilla and -rt will become even closer in the next future, until both are released the same day - the day when the CONFIG_PREEMPT_RT configuration item will appear in an unpatched vanilla kernel. This will, hopefully, be the day when real-time capabilities will be available in standard Linux distributions such as Ubuntu, Fedora and others.
