How does it work? What is the paradigm change? How should applications
behave to make better use of it? How should one profile the use of a
Gilad Ben-Yossef intended to give a talk about this, as well as some
related topics. His abstract (http://www.haifux.org/lectures/JIFFIE/) was:
How Time Flies: Jiffies, Hi-Res Timers and the Tickless Kernel - Gilad
This lecture, by Gilad Ben-Yossef, describes the Linux time keeping
mechanism and related features, covering:
- Jiffies and HZ: how the Linux kernel measure the passing of time
- Hi-Res Timers: Accuracy and precision of the Linux time keeping code
- Clock sources: abstractions of time keeping hardware
- Tick-less kernel: how the above contribute to a better Linux
performance in real time, power consumption and virtualization domains
