All,
I'm working on the emulator for OSF1/Mach for FreeBSD/Alpha, and I need
some help understanding how to do some things in the FreeBSD kernel--if anyone
can answer any of the following questions, it would be greatly appreciated:
1) How do you create a process in the kernel (i.e., you fork in
user-space...what's the analogue for kernel-space)?
2) How do you clone a process in kernel-space (i.e., in user-space, you would
fork and then share the entire process's memory space--how would you do such a
thing in kernel-space)?
3) What needs to be done to perform a context switch (from within the kernel),
and are there any MP considerations when doing this?
4) In what files do the proc and the u-area structures reside?
Thanks,
Andrew Miklic
