Re: Hurd SMP Project sketch

Hi Paul:

I'm a Spanish Computer Engineering student.   I have studied subjects like
Computer Architecture and Operating System Design, where I learn a few
internally concepts about processors, schedulers, MMUs... I am not an
expert, I'm only a student, but I think that this knowledge, with a few
helpful of experts,  can be enough to get finish this project.

In July, I did the first try, writing an ugly implementation of
cpu_number() and intel_startCPU() functions, but this didn't run.
You can view my work in https://github.com/AlmuHS/GNUMach_SMP

But, after this try, a friend said to me that the real problem is that
gnumach don't do the processor configuration to enable multiprocessing.
(currently, It's only multithreading, he said), so I decided to restart the
project from scratch, adding the hardware configuration needed to get a
real multiprocessor support.
