Linux Kernel 4.10 Released -- Happy Anniversary!

Kernel 4.10 has the honor of being christened the "Anniversary Edition" by Linus Torvalds. I'm guessing this is because of the recent 25th anniversary of the release of Linux 0.01. Admittedly, it is a bit late for that (the anniversary was back in September); however, Linus had not named any of the...

Real-time Linux has come a long way in the past decade. Jan Altenberg of Linutronix provides an overview of the topic and offers new RTL performance benchmarks in this video from ELC Europe.

Inside Real-Time Linux

Real-time Linux (RTL), a form of mainline Linux enabled with PREEMPT_RT, has come a long way in the past decade. Some 80 percent of the deterministic PREEMPT_RT patch is now available in the mainline kernel itself. Yet, backers of the strongest alternative to the single-kernel RTL on Linux -- the...
