Thomas Gleixner was recently invited to give the opening keynote at the 20th Euromicro Conference on Real-Time Systems, recently held in Brussels. He used this opportunity to talk about the disconnect between Linux kernel development and the academic research community as demonstrated by the history of realtime extensions to Linux. Now Thomas has written up his talk, along with some supplemental material and impressions from the conference, and contributed it to LWN. Click below (subscribers only) for a detailed look at how practical and academic realtime come together in Linux as only Thomas can tell it.
