Hello! Today we’re going to talk about a debugging tool we haven’t talked about much before on this blog: ftrace. What could be more exciting than a new debugging tool?! Better yet, ftrace isn’t new!

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...

Who Contributes to the Linux Kernel?

While many people tend to think of open source projects as being developed by passionate volunteers, the Linux kernel is mostly developed by people who are paid by their employers to contribute. According to The Linux Foundation, since 2005, “some 14,000 individual developers from over 1,300...
