Choosing Linux for New Use Cases

on YouTube ↗41m

" summary

Examines Linux options for new industries like Cloud, IoT, drones and robotics by comparing different kernel/maintenance choices—including the LTSI (Long-Term Support Initiative). Covers sector-specific requirements such as varying software lifetimes (3–5 to 10–20 years), the value of open-source practices (upstreaming, code modification and knowledge sharing), and explains how LTSI’s governance and roadmap help industry developers.

1. 0:00Intro
2. 0:28Who am I Tsugikazu SHIBATA, NEC • Founder and project lead of Long Term Support Initiative (LTSI) that will help industry people to use Long Term Stable kernel with helpful activities. • Involved Linux kernel community since 2.4 and also a board member of Linux Foundation
3. 1:22Linux is running everywhere Linux is running for multiple use cases - NYSE, London, Tokyo Stock Exchange - Amazon, Google, Facebook, Twitter - Android, TV, Camera, Router, Car navigation • Supports multiple architectures - x86, arm, s390, ia64, mips, parisc, sparc, sh ... • All those come from Single Source code tree
4. 5:41Linux development policy • Upstream is only the place to accept the patches - Reviewed by skilled maintainer - Tested with other proposals to confirm no conflicts - Follow the development process
5. 6:39Linux Development process • Just after the release of 4., two weeks of merge window will be opened for proposal of new features • After 2 weeks of merge window, -rch will be released and the stabilization will be started • 4.n+1 will be released when it becomes reasonably stable by some of-reX released
6. 7:48Kernel release cycle • Release cycle of Linux kernel is about 65days
7. 10:11Status of Latest Linux kernel Again • Latest released Kernel: 4.8 • Current Stable Kernel: 4.8.1 . Current development kernel in the merge window for 4.9-rci
8. 11:38LTS: Long Term Stable Kernel • Kernel tree continue to back port bug and Security fixes • Extended maintenance period for stable kernel • Pick one version per year and maintain 2 years
9. 12:20Why LTS? . Only the tree to get fixes from the community • In the real use case, tested/confirmed kernel is important, less important for new features • Fixes will be released # of times and should be applied frequently, Security/Bug fixes are being more important • Bugs found in LTS should be reported and fixed in upstream
10. 17:28Open Source community to create and maintain Linux kernel for long term -Based on LTS - Add another chance to include further patches on
11. 18:15LTSI Add vendor required features Share status, info, problem among industry people Huge testing by contributors Auto test framework Provide help to developer for upstream LTS Release 1 version/year, Maintain 2 years Frequently and large number of bug /security fies
12. 19:05History of LTSI • Established 2011 - 5 yeas now -Started for stable Kernel for Android • Integrated by Yocto (2012, May) • Have had a workshop/session to share information and discuss issue among industry people • Released yearly basis; 3.0, 3.4, 3.10, 3.14, 4.1
13. 20:42Shape of LTSI Project • Small staff to coordinate workshop, session at LF conference • Maintainer: Greg Kroah-Hartman, Fellow of Linux Foundation • Working with upstream Linux Community • Keeping neutral position to be able to use for variety of use case
14. 23:35LTSI as a part of Distro • Yocto project has a normal option to use LTSI - You can create your own distribution with LTSI - Yocto is doing their own tests for the distribution with LTSI. Both build distro and run it. Many of report/blog in the internet using Yocto and LTSI
15. 24:24Fuego: Auto test package • Jenkins based auto test packages (using Docker) - Distributed under 3-clause BSD license - Over 50 test packages included with Web based
16. 25:36Use Case: Automotive Grade Linux • Developing reference implementation called UCB (Unified Code Base) distribution v1.0 using LTSI 3.14 kernel - AGL/UCB is using Yocto and LTSI • Have had a demonstration at CES 2016 Las Vegas with announcement • V2.0 Brilliant Blowfish was released July 12 • V3.0 is planned to be released Jan. 2017
17. 27:04Use Case: Civil Infrastructure Platform • Established Feb 2016, by Toshiba, Hitachi, Siemens and others to create reference distribution for Civil infrastructure • One of major requirement includes Super Long Term Support: 10-15 years • Planning to take over maintenance of LTSI
18. 30:57LTSI Schedule expectation • Kernel Summit 2016 will be the time to decide LTS version
