how to debug the kernel (process scheduling)

Show all headers | View raw

I have a problem in how to debug the processes scheduling. First, I use the printk, the time slice is 50ms, so I can not see the message of print clearly.
Second, minix v3.1.0 does not support serail output and kgdb. 

I do the problems in chapter2 of "operating system Design and Implementation" .
45. Modify the MINIX 3 scheduler to keep track of how much CPU time each user process
has had recently. When no task or server wants to run, pick the user process that
has had the smallest share of the CPU.
