Re: multi-threaded Emacs

[Li Lin]

SMASH has many different implementations. Basically, we create one
kernel thread for each CPU(or core) in which a user-level thread
scheduler runs, and the thread is bounded to the corresponding CPU. The
context switches among user-level threads are done though a explicit
call to the function cthread_yield(). However, it is the native
scheduler that manages the kernel threads. 
So on uniprocessor machines, it is purely cooperative, on multi-CPU(or
-core) machines it is a mixture of cooperative and preemptive
threads. However, it is not difficult to modify it so that on
uniprocessor machine we still have more than one kernel threads.
I attached Kurt's thesis about SMASH. Although a lot of implementation
details has changed, his orginal thesis is still a good reference.
The attachment is a DVI file. If you can read it, then I can send you
the latex source of it, but you have to compile it by yourself.
