Google's Fuchsia OS Magenta Becomes Zircon

For those looking to follow the development of Google's Fuchsia operating system that is written from scratch, it's low-level Magenta core has been renamed to Zircon.

As a reminder, Fuchsia is a (non-Linux) real-time operating system developed by Google that has been under much public speculation since its code began appearing last year. Fuchsia uses a micro-kernel design with it being called Magenta.

Now discovered by this LLVM commit, it appears Magenta has been renamed to Zircon.

Confirming things, there is also now this Zircon Git repository. It's description states:
Zircon is the core platform that powers the Fuchsia OS. Zircon is composed of a microkernel (source in kernel/...) as well as a small set of userspace services, drivers, and libraries (source in system/...) necessary for the system to boot, talk to hardware, load userspace processes and run them, etc. Fuchsia builds a much larger OS on top of this foundation.
...
The Zircon Kernel provides syscalls to manage processes, threads, virtual memory, inter-process communication, waiting on object state changes, and locking (via futexes).

Currently there are some temporary syscalls that have been used for early bringup work, which will be going away in the future as the long term syscall API/ABI surface is finalized. The expectation is that there will be about 100 syscalls.

Zircon syscalls are generally non-blocking. The wait_one, wait_many port_wait and thread sleep being the notable exceptions.

It will certainly be interesting to see what becomes of Google Fuchsia in the years ahead.
