In this assignment you will write a LKM for the Linux kernel that displays the following details for all the processes whose PID is greater than an integer given by the user as a module parameter: [25 points]

PROCESS NAME

PID

STATE

PRIORITY

STATIC-PRIORITY

NORMAL-PRIORITY 1

As shown below, the PID is given as arguments while inserting the module in the kernel.

The next screenshot shows the required details for a process, its child processes (may have 0 or more), and its parent process. You are expected to keep a similar format (not an exact one) for your output which is readable. Your programs must compile and run under Xubuntu (or another variant of Ubuntu) 16.04.

You are to provide a short write up that illustrates what you found when looking at the Linux source les and documentation. Include the following:

For your main source le, describe the basic purpose of each of the module functions you had to implement.

For struct task_stuct (see Section 4), describe each element of struct that you used. Include which line number it was dened on.

For list.h (see Section 4), describe each function/macro you used to manipulate the list of executing processes (tasks).
