Programming sched.c

[pcheng]

Hello everyone,

I am new in the realm of linux programming but I am falling in the deep really fast. I need to start working with the scheduler in linux for my PhD and I was wondering if I could ask a few questions on this forum.

I want to know if I can change the sched.c file and how to recompile the code to check if it works after I do that. Or if there is a way of having a driver to drive the sched.c file without changing the kernel. This means that I can have a file which creates fake processes and tries to schedule them using the sched.c code.

Thanking you in advance,

a newbie

Are you telling me you're in a doctoral course that entails advanced kernel hacking, but they never taught you to recompile a kernel? What kind of school is this?! There are some rather good kernel compilation guides, just google for them.

My Master's was in networks but that is besides the point. I got into this realm and I need to learn how to do it to continue.

More important than all is to learn how to make a kernel image that can be bootable with the least amount of modules so that I can start working on scheduling alone. Knowing how to make a basic kernel and how to recompile it is my main consern now.

I appreciate the help. I am already googling for information but I just wanted to ask here in case someone can provide me with some insight.

Thanks.

Have a look at http://kernelnewbies.org/ . They have an article about scheduling in Linux as well: http://kernelnewbies.org/documents/schedule/ . I don't know if it is any help for you but I think it is a good starting point.
