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

6.

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

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

• Main goal was to stabilize and
prove the technology.
• Only used in reference devices

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

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

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

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.
