System Calls #8

Open rellermeyer opened 10 years ago

rellermeyer commented 10 years ago

We need the two "endpoints" for system call support: An entry.s like kernel-side system call handler and the corresponding syscall function in user space.

ghost commented 10 years ago

I'd like to work on this one.

jeffreyftang commented 10 years ago

@DWDenton - are you still planning on taking this on?

ghost commented 10 years ago

Yeah. Only have read a bit into it, so nothing started if you're also interested.

bolivier commented 10 years ago

I'm interested too.

jeffreyftang commented 10 years ago

Apparently this issue is part of a milestone that's due soon, so I'm just looking into what I can help out on.

ghost commented 10 years ago

Ah. I don't normally check Github often, so I didn't notice that. Just created system_calls branch to work on.

bolivier commented 10 years ago

Could we maybe meet at the GDC sometime this weekend to work on this?

ghost commented 10 years ago

Definitely. I have Saturday free before noon and from around 3 to 6. Sunday I get off work at 1 and am free until 6:30.

bolivier commented 10 years ago

I'm free anytime.

Jeffrey?

bolivier commented 10 years ago

So do you want to just meet in the GDC lab tomorrow at like 1:30 then?

ghost commented 10 years ago

Works for me.

jeffreyftang commented 10 years ago

Hey guys, sorry; I was at a wedding this weekend and wasn't checking github. I'm free to meet today at 1:30 in the lab.

StaticHex commented 9 years ago

I got system calls running and added a branch statement to hw_handlers.c

Nice! That will come in handy for those who were wondering how to work with interrupts.
