By: Carsten Emde

Several reports of the Eleventh Real Time Linux Workshop and on the RT mini summit are now available

LWN.net Executive Editor Jonathan Corbet kindly accepted our invitation to attend the Eleventh Real Time Linux Workshop that was held earlier this month in Dresden, Germany, where he gave an in-depth and highly appreciated talk on the current status and future plans of the Linux Kernel (the slides are here).

In addition, Jonathan and his colleague Jake Edge wrote a number of articles and reports on the Real Time Linux Workshop and on the preemption (RT) mini-summit. The latter was held the day before and on the first day of the Real Time Linux Workshop. Thank you, Jake and Jonathan, for all this great work!

Below are links to the various articles and related documents.
