Everything is in one address space.  It&amp;#x27;s actually Rocket, from Wind River, which also sells VxWorks and has open-sourced Rocket.  Zephyr is for very small systems. Think smart light bulb, not WiFi router.  Supported hardware includes the Arduno Due (ARM) and Arduino 101 (x86).  The QEMU emulator can be used for testing.  The API is C-oriented and very low level - fibers, threads, mailboxes, semaphores, etc.&lt;p&gt;[1] &lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;www.linuxfoundation.org&amp;#x2F;news-media&amp;#x2F;announcements&amp;#x2F;2016&amp;#x2F;02&amp;#x2F;linux-foundation-announces-project-build-real-time-operating-system&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;www.linuxfoundation.org&amp;#x2F;news-media&amp;#x2F;announcements&amp;#x2F;2016...&lt;/a&gt;</text><parent_chain></parent_chain></comment><story><title>Linux Foundation to support Zephyr microkernel</title><url>https://www.zephyrproject.org</url></story>
