hello there!
I have some questions, if you know about those, reply for me please.
(I use 4.3BSD....)

     1. I want to know how long one processor occupies CPU before
happening context  switching. In other words, how often does context
switching
happen. how can I change that time?(context switching interval)

     2. Is there any way to use math fuctions(for example,  log(),
sqrt() functions...) in kernel?

     3. Do you know how can I delay the message which pass by the
kernel?
         I wanna delay the message for some time in kernel.

thanks in advance for your reply..
have a good luck!...^.^;
