This document discusses Tizen, an open source operating system platform. It provides a brief history of Tizen, describing its initial focus on mobile devices and expansion to other product categories like smart watches, TVs and cameras. The document outlines the Tizen development process, including use of the Common and Yocto build systems. It demonstrates how to get started with Tizen development by joining the community, installing Tizen Common, and using tools like GBS to build software from source code repositories.

5. 5
A brief history of Tizen
• Announced in October 2011.
• One of the first Linux Foundation Collaborative Projects.

6. 6
Why The Linux Foundation?
• Neutral, non-profit organization.
• Already hosting large open source projects.
• Experience hosting operating systems.

7. 7
Early perceptions
• After the announcement, most people focused on mobile…
…but this was only part of the story
• Tizen was designed, from the start, to be used for
a large variety of devices

9. 9
Tizen 1.x
• The first official release of Tizen.
• Main goal was to stabilize and
prove the technology.
• Only used in reference devices

10. 10
Tizen 2.x
• First version to be used in real “Tizen” branded products.
• Mobiles: Samsung Z1
• Smart watches: Gear S2, Gear S, Gear 2, Gear 2 Neo
• Cameras: NX1, NX500, NX300M, NX300
• TVs: All 2015 smart TVs
• App Store launched (seller.tizenstore.com)
• Compliance program

11. 11
Tizen 3.x
• In development, lots of cool stuff on the way.
• Tizen split into “Profiles.”
• Changes to the technical governance.

12. 12
Why Tizen?
• Open Source has completely dominated the
consumer electronics industry.
• If you aren’t using Open Source in products,
you are very, very behind.
• Tizen allows companies to standardize on a single base,
so every new product is not running a new OS

13. Developement

14. 14
One platform for several products
• Retail products:
• built on Open source code:
• http://opensource.samsung.com
• belonging to some profile :
• Mobile, wearable, TV, camera …
• open to application developers (SDK)
• Tizen development platform:
• open development on http://tizen.org (since Tizen-3)
• is minimal (Basic UI/UX)
• but functional (security, application fw, web apps, Gfx)
• supports general purpose development hardware

15. 15
Tizen:Common
• Regular GNU/Linux distro (RPM based)
• Install on Intel, ARM (x86, x86_64), PC, VM, OSHW …
• It's not a profile but can be used as a base for profiles
• ie: 90% of Tizen:IVI is Tizen:Common
• Upstream is open to any developers
• and/or work with supported “Contrib repository”
• Platform developers use those tools:
• git, GBS, gerrit, OBS, zypper
• More: http://wiki.tizen.org/wiki/Common

16. 16
Tizen Yocto : an alternative to consider
• Drawbacks :
• GBS is Tizen official build system : source and binaries
• Tizen does not provide binaries to developers
• Benefit : standalone & extensible
• Contribute to it :
• tizen-distro (replaces Poky)
• meta-tizen : most of tizen software is here
• open-embedded : generic upstream
• or BSP layers : hardware adaptation
• Yocto and GBS projects are not interoperable.
• More : https://wiki.tizen.org/wiki/Tizen_on_Yocto_Project

17. 17
How To ?
• Join tizen.org
• Install tizen:common from http://download.tizen.org
• Setup tools : GBS (~/.gbs.conf)
• Build your sources or https://source.tizen.org/
• upstream/ : FLOSS components (unmodified)
• platform/ : Main Tizen code
• profile/ : profile specific
• contrib/ : community supported software
• ...
• Share patches http://review.tizen.org
• Interact with community : tracker, lists, IRC, ...

18. 18
Demo
• Boot Tizen:Common virtual machine
•
• Developer's tasks :
●
git clone
●
gbs build
●
zypper install
●
git push
●
gerrit review
