Sony experts present new kernel research and a tool to measure wake up latency at LinuxCon Japan

Next week, experienced Linux developers Frank Rowand (left) and Tim Bird (right) from Sony will be presenting at LinuxCon Japan, where many top Linux developers, administrators, users and experts will come together. Frank will share insights on how to use and understand the Real-Time Cyclictest benchmark, and Tim will explain how Linux developers can reduce the size of their Linux systems (and possible improve their performance in the process). Learn more the event and the presentations after the jump!
LinuxCon Japan is designed not only to encourage collaboration but to support future interaction between Japan and other Asia Pacific countries and the rest of the global Linux community. The conference includes presentations, tutorials, birds of a feather sessions, keynotes, and sponsored mini-summits.
Using and understanding the Real-Time Cyclictest benchmark
Frank Rowand has worked with real time Unix operating system since the early 90′s. Currently, his primary area of responsibility at Sony is embedded real time Linux for consumer and professional products. At LinuxCon Japan, his presentation is about how to make the most use of a native Linux tool called Cyclictest.
Cyclictest results are the most frequently cited real-time Linux metric, and the core concept of Cyclictest is very simple. However the test options are very extensive. So in this presentation, Frank will explore and explain the complexities of Cyclictest, and at the end of the talk, the audience will understand how Cyclictest results describe the potential real-time performance of a system.
Aggressive size reduction of the Linux kernel
Tim Bird has been working with Linux for over 20 years, and at Sony he helps to improve the Linux kernel for use in Sony’s products. Tim is also the Chair of the Architecture Group of the CE Working Group of the Linux Foundation, which is a group that seeks to improve Linux for use in consumer electronics products.
In his presentation at LinuxCon Japan, Tim will present research results from investigating new areas of kernel size optimisation, for devices with low memory footprints. This will include results from using gcc link-time optimization (LTO) with the ARM architecture (using Andi Kleen’s out-of-tree patches), as well as results and discussion of other optimisation techniques (including whole-system optimisation for embedded devices). This presentation is directed at kernel developers interested in reducing the size of their Linux systems (and possibly improving their performance in the process).
Meet Frank and Tim at LinuxCon Japan
If you plan to attend LinuxCon Japan, we welcome you to attend these sessions and come talk to Frank or Tim if you want to discuss the latest Linux research.
LinuxCon Japan will take place on May 29-31, 2013 at Chinzan-so Hotel & Conference Center  in Tokyo, Japan. Frank Rowand’s presentation takes place on May 29th at 2PM, and Tim Bird’s on May 29th at 3PM.
