Re: [Ksummit-discuss] [TECH TOPIC] UniLinux -- Unikernelized Linux Exploration

Hi Ted,

Looks I missed this email so really sorry for this delay response. When I went through ksummit-discuss today and just noticed this ☹

Overall, I didn't refactor too much into the big architecture of my proposal. But I'd like to 1>. go into something in detail with the participants ; 2>. talk a little bit new implementations. So besides of my original version, this time we would review-discuss them
1.  Reduce the source code
For example, I'm thinking if we can remove unnecessary kernel parameter sections while compiling. Furthermore, we need to extend this to syscall.
2.  Decouple the scheduler 
Do we still need to keep all schedulers work in terms of those unikernel cases running one process? Even this process is running with one thread or few threads sometime.
3.  Any refactors to some valuable use cases like a safety-critical application. What about classifying syscall to different levels?
4.  Others

Instead of making out my solution simply during those summits, plus, each part in the original version is not be implemented generally, so I think ksummit is supposed to a good chance to help me address these challenges properly. So this time, in terms of my proposal, I'm open to any technical solutions.

Thanks
Tiejun
