“supports” is too strong a word J

 

We have some internal research prototypes we use for exploring the research challenge of concurrency versus verification tractability, in addition to currency models for microkernels in general. Some of that code is probably what you have found. The code is likely to be highly experimental, and not what we are actively working on.

 

We have more mature research prototypes (still prototypes) internally that we a working towards releasing when time allows. I can’t give an accurate estimate, but it is likely to be in terms of weeks, not months.

Subject: [seL4] sel4 on multi-core

 

Hi All,

 

I think, on IA-32, sel4 supports multi-core machine.

But I do not how to use that. Here I have two specfic questions.

1. How to assign a specific core to a process/thread? And can I change this affinity?

 

2. How to two process/threads communicate via IPC on different cores?

I want to know some implementation details in kernel to support cross-core IPC.

Could anyone explain its logic or tell me the code for it in the kernel?

 

Thank you very much.

Best,

Yuxin
