Which just proves your lack of knowledge that those runtimes target generic commonly available general-purpose processors.

None of those products use FPGAs or custom ASICs.

Tone is not needed.

For TamaGo, it seems to allow developers run their application, not build an OS on the hardware. But I have not played with it, you are right.

> TamaGo is a framework that enables compilation and execution of unencumbered Go applications on bare metal

The environment does not seem to allow building a generic operating system [1]. F-Secure ported the runtime itself to boot natively. But please correct me.

> There is no thread support

The environment you run in is specifically curated for Go applications, such as the memory layout. I'd call this an "appliance" rather than enabling Go to be used for full-fledged generic operating system implementations.

Tone follows the last paragraph, returning ball.

An OS is an OS, regardless of the userspace.
