 ====== Frequently Asked Questions ======
-Here, you can list frequently asked questions from your students along with responses.
 ====== General ======
-===== Do I need to register for a CSE Computer Account? =====
+Question 1: For the test, do I need to know everything in the slides?
-Yes.
+Answer to Question 1: you will need to know everything in the slides, EXCEPT
+for things that I explicitly say that you don't need to know.
+For example, during the lectures, when I showed slides 31-32 of OSD4.pdf,
+"Fields of the VFS Superblock Object in Linux,"
+I said that you don't need to memorize all the names of the
+Fields of the VFS Superblock Object, UNLESS the name is mentioned
+in the slides.
+Here is one example: the field name "s_fs_info" is mentioned
+in slide 33, so you do need to memorize the field name "s_fs_info",
+and what it does.
+In general, you will need to know anything and everything that is discussed
+in the slides.
-===== Do I need to attend class? =====
+Question 2: For the project, do I need to perform a study of the whole Linux kernel? Can you provide an example of a Linux subsystem that would be of suitable scope for the project?
-If you wish to pass.
+Answer to Question 2: No, you are required to study ... __one__ or more __subsystems__ of the Linux kernel which provide some basic kernel functionality. You do not need to study the whole Linux kernel for your project.
-====== Tests ======
+"Memory Management", would be an example of a Linux subsystem that would be of suitable scope for the project. "Process Scheduling" would be another example of a Linux subsystem that would be of suitable scope for the project.
-===== Do I need to write all tests? =====
+Question 3: What is the main difference between the alternative (programming) project and the alternative (programming) assignment?
+Answer to Question 3: There is a significant difference in how the project will be evaluated
+compared with the assignment:
-... but of course.
+For the assignment, /cs/course/4221/4221a1F12alternative1.doc states that:
+"D. Evaluation of the Assignment
+Your assignment will be evaluated according to:
+(a) ...
+(b) ...
+(c ) The amount of effort involved in installing, setting up, and using the
+QNX Neutrino RTOS (Neutrino RTOS), and associated Development Tools,
+Middleware Software, Board Support Packages on the selected host and
+board."
+In contrast, for the project, /cs/course/4221/4221projectF12alternative1.doc states
+that:
+"D. Evaluation of the Project
+Your project will be evaluated according to:
+(a) The degree of sophistication of the laboratory experiments in the
+tutorial/manual; and the degree to which they teach how to exploit the
+capabilities of the QNX Neutrino RTOS (Neutrino RTOS) on the selected host
+and board.
+(b) ...
+(c ) ..."
+So the answer to Question 3 is that, compared with the assignment, the
+project is going to be evaluated according to:
+"The degree of sophistication of the laboratory experiments in the
+tutorial/manual; and the degree to which they teach how to exploit the
+capabilities of the QNX Neutrino RTOS (Neutrino RTOS) on the selected host
+and board."
+So in general, one would expect that, compared with the assignment, the
+project should:
+. demonstrate a much higher "degree of sophistication of the laboratory experiments in the tutorial/manual;"
+. teach to a much more sophisticated degree, "how to exploit the
+capabilities of the QNX Neutrino RTOS (Neutrino RTOS) on the selected host
+and board."
+Question 4: Can you recommend some books for helping to understand the material in the slides in OSD.5 and OSD.6?
+Answer to Question 4: Unfortunately, no books cover all the material in the slides in OSD.5 and OSD.6.
+However, reading Chapter 5, “Kernel Synchronization”, of the book, “Understanding the Linux Kernel”, 3rd Edition, may help understand some of the material on synchronization in the slides in OSD.5.pdf. Reading Chapter 1 to Chapter 3 of the book "MicroC/OS-II The Real-Time Kernel", 2nd Edition, may help understand some of the material on μC/OS-II in the slides in OSD.6.pdf.
