boost.coroutine uses boost.context for context switching and therefore you have to add support for the numerous architectures to boost.context in order to get boost.coroutine working on those CPUs.

take a look in documentation of boost.context

no - it is cooperative

of course otherwise it would not work -> ABI

adapt boost.context for the specific architecture/ABI

yes - one of ctor's argument
