[seL4] Re: Thread Scheduling Domains

Hi June, yes, if you're using the static domain scheduler, then that file needs to be overridden with the schedule you want. Depending on what you're trying to do, the domain scheduler might not be the right tool for the job. It really is fully compile-time static. Cheers, Gerwin

Hey folks,

So Sam and I are at the point now where we're attempting to get our untrusted user threads running in a different scheduling domain, and it's not exactly clear how this is supposed to work in terms of enabling more than one domain in the kernel.

So far, I've set KernelNumDomains to 2 in the easy-settings.cmake for our project, but unless I provide a separate implementation of kernel/config/default_domain.c by overriding KernelDomainSchedule, the resulting kernel will only think it has one domain and only ever schedule domain 0 for execution.

Are we expected to override the default_domain.c file with our own in the project, like sel4test seems to do?

Thanks!
