Trampoline code question

[nexos]

Hello,
I was wondering what the best method to load trampoline code for SMP is. How do you embed it in a section in the executable?
Thanks,

I'm not quite sure what the problem is. You just link it in to the kernel object file in the same way as any other code.

I do it as normal assembly subroutine, but written in position independed fashion. Then copy it somewhere below first meg, so it can be reached with startup IPI.

Thank you both. I was making a problem when there was no problem

Wait so an elf32 binary can contain 16 bit code?

And 64 bit too. It can be a little bit problematic to link, since not every type of relocation can be applied, but it sure can be done.
