Hi,
I'm very interested in this project.
For 3 reasons, first, it uses a LINUX as a host OS and then changes it
to a guest OS, so a running host OS was saved.
Second, less virtualization and more real-time.
Third, it's easy to use.
So, I want to evaluate the feasibility of using it in an automotive system.
I want to know is it mature enough to already been used in some
products, so I can use this information to enhance the customer's
confidence.
And if it has not been used for products, why?
Looking forward to your reply.
Jailhouse is primarily useful in two application areas. One is
real-time, splitting of high-performance cores in a AMP setups without
much hacking while providing minimal latencies. There are users out
there, at least one stepped forward officially, see [1]. Furthermore,
Jailhouse is part of processor SDKs that TI and NXP are shipping to
their customers, and not only that just led to [2] - which I think
speaks for itself.
The second, still more research-like area is functional safety. This is
our (Siemens) primary focus with Jailhouse. And while we are still
waiting for and even collaborating on developing [3] a certifiable
high-performance multicore hardware, our discussions with external
experts and certification authority made us confident that a key element
of the software for complex mixed-critial multicore systems - Jailhouse
- will be very well suited and efficiently usable. Once we have a hardware.
