== About the Systems Laboratory ==

[http://www.mu.edu/ Marquette]'s [[Systems Laboratory]], under the direction of [http://www.mscs.mu.edu/~brylow/ Dr. Dennis Brylow] in the [http://www.mscs.mu.edu/ Department of Mathematics, Statistics, and Computer Science], is housed on the third floor of Cudahy Hall.

The lab creates new tools and methods for building and studying complex computer systems. Our emphasis is on embedded, real-time, and network systems, with strong ties to the electrical and computer engineering community, and the computer science education community. Current projects include:

1. Experimental Embedded Networking Platform. Creation of laboratory infrastructure and software for research and education in the area of embedded networking appliances, particularly wireless routers and IP telephony. Collaboration with Cisco Systems Advanced Research Division.

2. Experimental Embedded Operating System Laboratory. Creation of laboratory infrastructure and software for research and education in area of embedded operating systems. Collaboration with University of Buffalo and University of Mississippi, with funding from the National Science Founcation.

3. Embedded Software Transactional Memory. Exploration of an innovative transactional memory model for guaranteeing process synchronization in embedded operating systems. Collaboration with Intel Research.

The Systems Lab will host three undergraduate [http://acm.mscs.mu.edu/reu REU] (Research Experience for Undergraduates) students in summer 2010, funded by the MU's College of Arts and Sciences. They will be working on ports of the Embedded Xinu operating system to new embedded platforms, embedded network emulation, and multicore embedded systems.

== About the Systems Laboratory ==

[http://www.mu.edu/ Marquette]'s [[Systems Laboratory]], under the direction of [http://www.mscs.mu.edu/~brylow/ Dr. Dennis Brylow] in the [http://www.mscs.mu.edu/ Department of Mathematics, Statistics, and Computer Science], is housed on the third floor of Cudahy Hall.

The lab creates new tools and methods for building and studying complex computer systems. Our emphasis is on embedded, real-time, and network systems, with strong ties to the electrical and computer engineering community, and the computer science education community. Current projects include:

1. Experimental Embedded Networking Platform. Creation of laboratory infrastructure and software for research and education in the area of embedded networking appliances, particularly wireless routers and IP telephony. Collaboration with Cisco Systems Advanced Research Division.

2. Experimental Embedded Operating System Laboratory. Creation of laboratory infrastructure and software for research and education in area of embedded operating systems. Collaboration with University of Buffalo and University of Mississippi, with funding from the National Science Founcation.

3. Embedded Software Transactional Memory. Exploration of an innovative transactional memory model for guaranteeing process synchronization in embedded operating systems. Collaboration with Intel Research.

The Systems Lab will host three undergraduate [http://acm.mscs.mu.edu/reu REU] (Research Experience for Undergraduates) students in summer 2010, funded by the MU's College of Arts and Sciences. They will be working on ports of the Embedded Xinu operating system to new embedded platforms, embedded network emulation, and multicore embedded systems.

1. Experimental Embedded Networking Platform. Creation of laboratory infrastructure and software for research and education in the area of embedded networking appliances, particularly wireless routers and IP telephony. Collaboration with Cisco Systems Advanced Research Division.

2. Experimental Embedded Operating System Laboratory. Creation of laboratory infrastructure and software for research and education in area of embedded operating systems. Collaboration with University of Buffalo and University of Mississippi, with funding from the National Science Founcation.

3. Embedded Software Transactional Memory. Exploration of an innovative transactional memory model for guaranteeing process synchronization in embedded operating systems. Collaboration with Intel Research.

The Systems Lab will host three undergraduate [http://acm.mscs.mu.edu/reu REU] (Research Experience for Undergraduates) students in summer 2010, funded by the MU's College of Arts and Sciences. They will be working on ports of the Embedded Xinu operating system to new embedded platforms, embedded network emulation, and multicore embedded systems.

I thought that was weird, so I used the ''-f'' force option [resulting in ''rm -rf ~'']. When I tried to use ''make'', it said file not found and that is when I realized I deleted my home directory."
* AM: What does that mean? / MS: You can't eat Catholics on Friday.

* KT: I use tilde all the time. / DB: Maybe a little too much.
* KT: [after using a configure script that accidentally made a directory named ~] "I was trying to remove the ~ directory. I tried ''rm -r ~'' and the system complained about files in use. I thought that was weird, so I used the ''-f'' force option [resulting in ''rm -rf ~'']. When I tried to use ''make'', it said file not found and that is when I realized I deleted my home directory."
* AM: What does that mean? / MS: You can't eat Catholics on Friday.
* DB: These little details are like sorting your M&Ms by color before you eat them. / ZL [who is color deficient]: I always do that. It's good practice. / DB: Bad example.

Assignment: LL/SC

2010-03-05T03:32:43Z

Akoehler: /* Lab Report */

[[Category:Student Built Xinu]]
= Synchronization and Interprocess Communication =
This assignment is a [[Xinu]] assignment allowing the student to grow a more firm understanding of how an operating system works. This assignment is part of the [[Student Built Xinu]] track for professors that are [[Teaching With Xinu]]. Written answers to the analysis questions should be put into a file called <code>system/ANALYSIS.txt</code> and submitted with the code. The entire directory containing the operating system should be turned in during the submission process.

This assignment includes a LAB REPORT. Include your lab report in a file called <code>login.pdf</code>, (with your login name,) in the top-level directory of your xinu-hw6.

After completion of this assignment we will have a basic operating system with preemptive, priority scheduling of processes, counting semaphores with wait queues as synchronization primitives and interprocess communication with bounded buffers.

== Atomicity ==
In a system with preemption, we must now guard against being interrupted while in the middle of an atomic operation. There are many points in operating system code where an unfortunately timed interrupt could leave the system in an inconsistent state.

For example, in the <code>resched()</code> function, there are several lines of C code (which translate into many more lines of machine code) between the point where the outgoing running process is put back into the queue of ready processes and the point where an incoming process is dequeued and set to running. If an interrupt were to take place in the midst of this transition, the interrupt handling code might see the system in an inconsistent state, in which there doesn't seem to be a currently running process. For this reason, we consider process rescheduling to be atomic with respect to the rest of the operating system. The easiest way to enforce this is to temporarily disable interrupts during a critical, atomic section of code, and then reenable them when done.

The new file <code>system/intr.S</code> contains functions <code>enable()</code>, <code>disable()</code>, and <code>restore()</code> for manipulating the master bit that enables processor interrupts. From this point forward, these functions must be used judiciously to guard atomic sections in the operating system functions you write.

== Preparation ==
First, make a fresh copy of your work thus far.
cp -R <old Xinu directory> <new Xinu directory>
Untar the new project files on top of this new directory:
tar xvzf <tar-ball location>
You should now see the new project files in with your old files. Be certain to make clean before compiling for the first time.

== Semaphores ==
With this assignment you must learn about and understand classic semaphores before using them to implement the remainder of the assignment. An implementation of classic semaphores with waiting queues has been provided for you. Please examine and understand the implementation which can be found across several files including <code>include/semaphore.h</code>, <code>system/newsem.c</code>, system/signal.c and <code>system/wait.c</code>. As part of the analysis portion of this assignment, you will need to write a main file to show your understanding of semaphores.

== Producers/Consumers ==
Using the provided semaphore structure, implement producers and consumers that communicate using a Bounded-Buffer. Your textbook provides discussion of the Bounded-Buffer Problem beginning in section 6.6.1, and outlines this assignment as Programming Project 6.40 - Producer-Consumer Problem.

Segments of the textbook code are already given for you in <code>system/testcases.c</code>. Complete the project as specified in the text with slight adjustments as noted in the testcases TODOs. Answer the analysis questions below in your lab report.

== Synchronization Hardware ==
Disabling all interrupts is an effective but heavy-handed approach for providing mutual exclusion. Multicore systems and complex real-time systems often cannot afford to disable interrupts, and rely more on hardware support for atomic updates.

The assembly code in <code>system/testAndSet.S</code> implements the <code>testAndSet()</code> operation (ala Figure 6.4 in your textbook<ref name="textbook">Silberschatz, A., Galvin, P. B., and Gagne, G. 2009 Operating System Concepts. 8th. John Wiley & Sons, Inc.</ref>) using the MIPS LL/SC (load-linked and store-conditional) opcodes. Much more complex synchronization primitives can be built on top of simple atomic opcode combinations such as there.

Build <code>mutexAcquire()</code> and <code>mutexRelease()</code> in <code>system/mutex.c</code> using the bounded-waiting algorithm presented in Figure 6.8 of your textbook<ref name="textbook" />.

== Lab Report ==
For the lab report portion of this assignment, you should typeset a document containing your analysis of the system components introduced. A sample report format is given [http://xinu/wiki/images/b/b6/Labreport.pdf HERE]. We expect the report to be written with your exemplary literacy skills.

What are we reporting on? Once you have the Producer/Consumer implementation working with the provided semaphore API, consider the following questions:
# Does it matter which process runs first, the producer or the consumer?
# What happens when there are multiple producers and consumers?
# What happens when the producer(s) priority is higher than the consumer(s)? Vice-versa?

For each of these, form a hypothesis, construct an experiment (testcases), and draw appropriate conclusions. There is no benefit in fudging your hypotheses after you know the answer; the quality of a lab report is orthogonal to whether your hypothesis was correct or not.

For part two of the assignment, use your bounded-wait <code>mutexAcquire()</code> and <code>mutexRelease()</code> to prevent your producers/consumers from breaking up <code>kprintf()</code> calls mid-line without additional disabling of interrupts. Consider the following questions:

# Can your bounded-wait mutex subsystem replace the semaphore subsystem for this task?
# Under what conditions in the embedded operating system will the mutex subsystem not work as designed?
# Can you deadlock your producer and consumer?

I rewrote the <code>testAndSet()</code> MIPS code from lab today to correspond more closely to the semantics used in the textbook chapter 6<ref name="textbook"/>. There is an example of the [http://xinu/wiki/images/b/b6/Labreport.pdf lab report format], and analysis questions to report upon in the final section. Typeset your lab report with whatever software you are comfortable with.

Please examine and understand the implementation which can be found across several files including <code>include/semaphore.h</code>, <code>system/newsem.c</code>, system/signal.c and <code>system/wait.c</code>. As part of the analysis portion of this assignment, you will need to write a main file to show your understanding of semaphores.

== Producers/Consumers ==
Using the provided semaphore structure, implement producers and consumers that communicate using a Bounded-Buffer. Your textbook provides discussion of the Bounded-Buffer Problem beginning in section 6.6.1, and outlines this assignment as Programming Project 6.40 - Producer-Consumer Problem.

Segments of the textbook code are already given for you in <code>system/testcases.c</code>. Complete the project as specified in the text with slight adjustments as noted in the testcases TODOs. Answer the analysis questions below in your lab report.

== Synchronization Hardware ==
Disabling all interrupts is an effective but heavy-handed approach for providing mutual exclusion. Multicore systems and complex real-time systems often cannot afford to disable interrupts, and rely more on hardware support for atomic updates.

The assembly code in <code>system/testAndSet.S</code> implements the <code>testAndSet()</code> operation (ala Figure 6.4 in your textbook<ref name="textbook">Silberschatz, A., Galvin, P. B., and Gagne, G. 2009 Operating System Concepts. 8th. John Wiley & Sons, Inc.</ref>) using the MIPS LL/SC (load-linked and store-conditional) opcodes. Much more complex synchronization primitives can be built on top of simple atomic opcode combinations such as there.

Build <code>mutexAcquire()</code> and <code>mutexRelease()</code> in <code>system/mutex.c</code> using the bounded-waiting algorithm presented in Figure 6.8 of your textbook<ref name="textbook" />.

== Lab Report ==
For the lab report portion of this assignment, you should typeset a document containing your analysis of the system components introduced. A sample report format is given [http://xinu/wiki/images/b/b6/Labreport.pdf HERE]. We expect the report to be written with your exemplary literacy skills.

What are we reporting on? Once you have the Producer/Consumer implementation working with the provided semaphore API, consider the following questions:
# Does it matter which process runs first, the producer or the consumer?
# What happens when there are multiple producers and consumers?
# What happens when the producer(s) priority is higher than the consumer(s)? Vice-versa?

For each of these, form a hypothesis, construct an experiment (testcases), and draw appropriate conclusions. There is no benefit in fudging your hypotheses after you know the answer; the quality of a lab report is orthogonal to whether your hypothesis was correct or not.

For part two of the assignment, use your bounded-wait <code>mutexAcquire()</code> and <code>mutexRelease()</code> to prevent your producers/consumers from breaking up <code>kprintf()</code> calls mid-line without additional disabling of interrupts. Consider the following questions:

# Can your bounded-wait mutex subsystem replace the semaphore subsystem for this task?
# Under what conditions in the embedded operating system will the mutex subsystem not work as designed?
# Can you deadlock your producer and consumer?

I rewrote the <code>testAndSet()</code> MIPS code from lab today to correspond more closely to the semantics used in the textbook chapter 6 <ref name="textbook"/>. There is an example of the [http://xinu/wiki/images/b/b6/Labreport.pdf lab report format], and analysis questions to report upon in the final section. Typeset your lab report with whatever software you are comfortable with.

[[Category:Student Built Xinu]]
= Synchronization and Interprocess Communication =
This assignment is a [[Xinu]] assignment allowing the student to grow a more firm understanding of how an operating system works. This assignment is part of the [[Student Built Xinu]] track for professors that are [[Teaching With Xinu]]. Written answers to the analysis questions should be put into a file called <code>system/ANALYSIS.txt</code> and submitted with the code. The entire directory containing the operating system should be turned in during the submission process.

This assignment includes a LAB REPORT. Include your lab report in a file called <code>login.pdf</code>, (with your login name,) in the top-level directory of your xinu-hw6.

After completion of this assignment we will have a basic operating system with preemptive, priority scheduling of processes, counting semaphores with wait queues as synchronization primitives and interprocess communication with bounded buffers.

== Atomicity ==
In a system with preemption, we must now guard against being interrupted while in the middle of an atomic operation. There are many points in operating system code where an unfortunately timed interrupt could leave the system in an inconsistent state.

For example, in the <code>resched()</code> function, there are several lines of C code (which translate into many more lines of machine code) between the point where the outgoing running process is put back into the queue of ready processes and the point where an incoming process is dequeued and set to running. If an interrupt were to take place in the midst of this transition, the interrupt handling code might see the system in an inconsistent state, in which there doesn't seem to be a currently running process. For this reason, we consider process rescheduling to be atomic with respect to the rest of the operating system. The easiest way to enforce this is to temporarily disable interrupts during a critical, atomic section of code, and then reenable them when done.

The new file <code>system/intr.S</code> contains functions <code>enable()</code>, <code>disable()</code>, and <code>restore()</code> for manipulating the master bit that enables processor interrupts. From this point forward, these functions must be used judiciously to guard atomic sections in the operating system functions you write.

== Preparation ==
First, make a fresh copy of your work thus far.
cp -R <old Xinu directory> <new Xinu directory>
Untar the new project files on top of this new directory:

You should now see the new project files in with your old files. Be certain to make clean before compiling for the first time.

An implementation of classic semaphores with waiting queues has been provided for you.

[[Category:Student Built Xinu]]
= Synchronization and Interprocess Communication =
This assignment is a [[Xinu]] assignment allowing the student to grow a more firm understanding of how an operating system works. This assignment is part of the [[Student Built Xinu]] track for professors that are [[Teaching With Xinu]]. Written answers to the analysis questions should be put into a file called <code>system/ANALYSIS.txt</code> and submitted with the code. The entire directory containing the operating system should be turned in during the submission process.

This assignment includes a LAB REPORT. Include your lab report in a file called <code>login.pdf</code>, (with your login name,) in the top-level directory of your xinu-hw6.

After completion of this assignment we will have a basic operating system with preemptive, priority scheduling of processes, counting semaphores with wait queues as synchronization primitives and interprocess communication with bounded buffers.

== Atomicity ==
In a system with preemption, we must now guard against being interrupted while in the middle of an atomic operation. There are many points in operating system code where an unfortunately timed interrupt could leave the system in an inconsistent state.

For example, in the <code>resched()</code> function, there are several lines of C code (which translate into many more lines of machine code) between the point where the outgoing running process is put back into the queue of ready processes and the point where an incoming process is dequeued and set to running. If an interrupt were to take place in the midst of this transition, the interrupt handling code might see the system in an inconsistent state, in which there doesn't seem to be a currently running process. For this reason, we consider process rescheduling to be atomic with respect to the rest of the operating system. The easiest way to enforce this is to temporarily disable interrupts during a critical, atomic section of code, and then reenable them when done.

The new file <code>system/intr.S</code> contains functions <code>enable()</code>, <code>disable()</code>, and <code>restore()</code> for manipulating the master bit that enables processor interrupts. From this point forward, these functions must be used judiciously to guard atomic sections in the operating system functions you write.

== Preparation ==
First, make a fresh copy of your work thus far.
cp -R <old Xinu directory> <new Xinu directory>
Untar the new project files on top of this new directory:
tar xvzf <tar-ball location>
You should now see the new project files in with your old files. Be certain to make clean before compiling for the first time.

== Semaphores ==
With this assignment you must learn about and understand classic semaphores before using them to implement the remainder of the assignment. An implementation of classic semaphores with waiting queues has been provided for you. Please examine and understand the implementation which can be found across several files including <code>include/semaphore.h</code>, <code>system/newsem.c</code>, system/signal.c and <code>system/wait.c</code>. As part of the analysis portion of this assignment, you will need to write a main file to show your understanding of semaphores.

== Producers/Consumers ==
Using the provided semaphore structure, implement producers and consumers that communicate using a Bounded-Buffer. Your textbook provides discussion of the Bounded-Buffer Problem beginning in section 6.6.1, and outlines this assignment as Programming Project 6.40 - Producer-Consumer Problem.

Segments of the textbook code are already given for you in <code>system/testcases.c</code>. Complete the project as specified in the text with slight adjustments as noted in the testcases TODOs. Answer the analysis questions below in your lab report.

== Synchronization Hardware ==
Disabling all interrupts is an effective but heavy-handed approach for providing mutual exclusion. Multicore systems and complex real-time systems often cannot afford to disable interrupts, and rely more on hardware support for atomic updates.

The assembly code in <code>system/testAndSet.S</code> implements the <code>testAndSet()</code> operation (ala Figure 6.4 in your textbook <ref name="textbook">Silberschatz, A., Galvin, P. B., and Gagne, G. 2009 Operating System Concepts. 8th. John Wiley & Sons, Inc.</ref>) using the MIPS LL/SC (load-linked and store-conditional) opcodes. Much more complex synchronization primitives can be built on top of simple atomic opcode combinations such as there.

Build <code>mutexAcquire()</code> and <code>mutexRelease()</code> in <code>system/mutex.c</code> using the bounded-waiting algorithm presented in Figure 6.8 of your textbook<ref name="textbook" />.

== Lab Report ==
For the lab report portion of this assignment, you should typeset a document containing your analysis of the system components introduced. A sample report format is given [http://xinu/wiki/images/b/b6/Labreport.pdf HERE]. We expect the report to be written with your exemplary literacy skills.

What are we reporting on? Once you have the Producer/Consumer implementation working with the provided semaphore API, consider the following questions:
# Does it matter which process runs first, the producer or the consumer?
# What happens when there are multiple producers and consumers?
# What happens when the producer(s) priority is higher than the consumer(s)? Vice-versa?

For each of these, form a hypothesis, construct an experiment (testcases), and draw appropriate conclusions. There is no benefit in fudging your hypotheses after you know the answer; the quality of a lab report is orthogonal to whether your hypothesis was correct or not.

For part two of the assignment, use your bounded-wait <code>mutexAcquire()</code> and <code>mutexRelease()</code> to prevent your producers/consumers from breaking up <code>kprintf()</code> calls mid-line without additional disabling of interrupts. Consider the following questions:

# Can your bounded-wait mutex subsystem replace the semaphore subsystem for this task?
# Under what conditions in the embedded operating system will the mutex subsystem not work as designed?
# Can you deadlock your producer and consumer?

[[Category:Teaching With Xinu]]
[[Category:Student Built Xinu]]
== Overview ==
Having students build their own [[Xinu]] is one of the potential tracks presented for a professor that is [[Teaching With Xinu]].

A student built operating system puts the student in the trenches of operating system development. The student will become intimately involved with the inner workings of an operating system. This will give the student a better understanding of the various systems that work together behind the scenes while an operating system is running. Operating systems topics that can be incorporated in a student built Xinu course include: memory management, scheduling, concurrent processing, device management, file systems and others.
== Course Outcomes ==
Course development can parallel learning objectives and topics associated with many Communication and Networking courses. [[Student Built Xinu#References|[1]]]

=== Topics ===
* Overview of operating systems
* Operating system principles
* Concurrency
* Scheduling and dispatch
* Memory management
* Device management
* Security and protection
* File systems
* Evaluating system performance

=== Learning Objectives ===
* Discuss the history of operating systems.
* Overview of the general and specific purpose of an operating system.
* Understanding concurrency and state flow diagrams.
* Understanding deadlock and starvation.
* Ability to decipher between scheduling algorithms.
* Understanding the use of memory and virtual memory.
* Characteristics of serial and parallel devices.
* Deciphering the concepts behind various file systems
* Understanding the necessity of security and locating potential system security holes

== Potential Course Structure ==
An Operating Systems course using the below course outline or something similar will introduce students to some fundamental concepts of operating systems combined with the basics of networking and communications. Topics include: memory management, scheduling, concurrent processing, device management, file systems, networking, security, and system performance. A similar course structure is followed by [http://www.mscs.mu.edu/~brylow Dr. Dennis Brylow] at Marquette University in his sophomore level Operating Systems course. Most of the assignments where students are building Embedded Xinu are done in teams of two.

Assignment: LL/SC

2010-03-05T02:35:08Z

Akoehler: /* Synchronization and Interprocess Communication */

[[Category:Student Built Xinu]]
= Synchronization and Interprocess Communication =
This assignment is a [[Xinu]] assignment allowing the student to grow a more firm understanding of how an operating system works. This assignment is part of the [[Student Built Xinu]] track for professors that are [[Teaching With Xinu]]. Written answers to the analysis questions should be put into a file called <code>system/ANALYSIS.txt</code> and submitted with the code. The entire directory containing the operating system should be turned in during the submission process.

This assignment includes a LAB REPORT. Include your lab report in a file called <code>login.pdf</code>, (with your login name,) in the top-level directory of your xinu-hw6.

After completion of this assignment we will have a basic operating system with preemptive, priority scheduling of processes, counting semaphores with wait queues as synchronization primitives and interprocess communication with bounded buffers.

== Atomicity ==
In a system with preemption, we must now guard against being interrupted while in the middle of an atomic operation. There are many points in operating system code where an unfortunately timed interrupt could leave the system in an inconsistent state.

For example, in the <code>resched()</code> function, there are several lines of C code (which translate into many more lines of machine code) between the point where the outgoing running process is put back into the queue of ready processes and the point where an incoming process is dequeued and set to running. If an interrupt were to take place in the midst of this transition, the interrupt handling code might see the system in an inconsistent state, in which there doesn't seem to be a currently running process. For this reason, we consider process rescheduling to be atomic with respect to the rest of the operating system. The easiest way to enforce this is to temporarily disable interrupts during a critical, atomic section of code, and then reenable them when done.

The new file <code>system/intr.S</code> contains functions <code>enable()</code>, <code>disable()</code>, and <code>restore()</code> for manipulating the master bit that enables processor interrupts. From this point forward, these functions must be used judiciously to guard atomic sections in the operating system functions you write.

== Preparation ==
First, make a fresh copy of your work thus far.
cp -R <old Xinu directory> <new Xinu directory>
Untar the new project files on top of this new directory:
tar xvzf <tar-ball location>
You should now see the new project files in with your old files. Be certain to make clean before compiling for the first time.

== Semaphores ==
With this assignment you must learn about and understand classic semaphores before using them to implement the remainder of the assignment. An implementation of classic semaphores with waiting queues has been provided for you. Please examine and understand the implementation which can be found across several files including <code>include/semaphore.h</code>, <code>system/newsem.c</code>, system/signal.c and <code>system/wait.c</code>. As part of the analysis portion of this assignment, you will need to write a main file to show your understanding of semaphores.

== Producers/Consumers ==
Using the provided semaphore structure, implement producers and consumers that communicate using a Bounded-Buffer. Your textbook provides discussion of the Bounded-Buffer Problem beginning in section 6.6.1, and outlines this assignment as Programming Project 6.40 - Producer-Consumer Problem.

Segments of the textbook code are already given for you in <code>system/testcases.c</code>. Complete the project as specified in the text with slight adjustments as noted in the testcases TODOs. Answer the analysis questions below in your lab report.

== Synchronization Hardware ==
Disabling all interrupts is an effective but heavy-handed approach for providing mutual exclusion. Multicore systems and complex real-time systems often cannot afford to disable interrupts, and rely more on hardware support for atomic updates.

The assembly code in <code>system/testAndSet.S</code> implements the <code>testAndSet()</code> operation (ala Figure 6.4 in your textbook <ref name="textbook">Silberschatz, A., Galvin, P. B., and Gagne, G. 2009 Operating System Concepts. 8th. John Wiley & Sons, Inc.</ref>) using the MIPS LL/SC (load-linked and store-conditional) opcodes. Much more complex synchronization primitives can be built on top of simple atomic opcode combinations such as there.

Build <code>mutexAcquire()</code> and <code>mutexRelease()</code> in <code>system/mutex.c</code> using the bounded-waiting algorithm presented in Figure 6.8 of your textbook<ref name="textbook" />.

== Lab Report ==
For the lab report portion of this assignment, you should typeset a document containing your analysis of the system components introduced. A sample report format is given [http://xinu/wiki/images/b/b6/Labreport.pdf HERE]. We expect the report to be written with your exemplary literacy skills.

What are we reporting on? Once you have the Producer/Consumer implementation working with the provided semaphore API, consider the following questions:
# Does it matter which process runs first, the producer or the consumer?
# What happens when there are multiple producers and consumers?
# What happens when the producer(s) priority is higher than the consumer(s)? Vice-versa?

For each of these, form a hypothesis, construct an experiment (testcases), and draw appropriate conclusions. There is no benefit in fudging your hypotheses after you know the answer; the quality of a lab report is orthogonal to whether your hypothesis was correct or not.

For part two of the assignment, use your bounded-wait <code>mutexAcquire()</code> and <code>mutexRelease()</code> to prevent your producers/consumers from breaking up <code>kprintf()</code> calls mid-line without additional disabling of interrupts. Consider the following questions:

# Can your bounded-wait mutex subsystem replace the semaphore subsystem for this task?
# Under what conditions in the embedded operating system will the mutex subsystem not work as designed?
# Can you deadlock your producer and consumer?

I rewrote the <code>testAndSet()</code> MIPS code from lab today to correspond more closely to the semantics used in the textbook chapter 6<ref name="textbook">. There is an example of the [http://xinu/wiki/images/b/b6/Labreport.pdf lab report format], and analysis questions to report upon in the final section. Typeset your lab report with whatever software you are comfortable with.

Akoehler: /* Spring 2010 */

== Spring 2010 ==
* KT: I use tilde all the time. DB: Maybe a little too much.
* KT: [after using a configure script that accidentally made a directory named ~] "I was trying to remove the ~ directory. I tried ''rm -r ~'' and the system complained about files in use. I thought that was weird, so I used the ''-f'' force option [resulting in ''rm -rf ~'']. When I tried to use ''make'', it said file not found and that is when I realized I deleted my home directory."

Student Extended Xinu

2010-03-01T18:14:34Z

Akoehler: /* Course Outline */

[[Category:Teaching With Xinu]]
[[Category:Student Extended Xinu]]
== Overview ==
Having students integrate advanced operating systems features and develop applications for a their own or a provided [[Xinu]] operating system is one of the potential tracks presented for a professor that is [[Teaching With Xinu]].

Students will learn to extend an operating system by adding kernel level and user level applications. Given a functional Embedded Xinu operating system the students will have to understand and manipulate existing operating system code to create additional operating system features. To add more applications to the operating system students will have to understand the interactions between the program in design and the operating system's device and kernel interaction calls. Programming for embedded devices allows students to engage in development on small resource constrained environments. Through extending the existing Embedded Xinu operating system a student learns to use and understand code not written by the student and develops advanced operating system concepts.

== Course Outcomes ==
Course development can parallel learning objectives and topics associated with many Communication and Networking courses. [[Student Built Xinu#References|[1]]]

=== Topics ===
* Overview of operating systems
* Operating system principles
* Concurrency
* Scheduling and dispatch
* Memory management
* Device management
* Security and protection
* File systems
* Evaluating system performance

=== Learning Objectives ===
* Intimate knowledge of embedded devices.
* Overview of the general and specific purpose of an operating system.
* Understanding concurrency and state flow diagrams.
* Understanding deadlock and starvation.
* Understanding the use of memory and virtual memory.
* Characteristics of serial and parallel devices.

== Potential Course Structure ==
A course where having students integrate advanced operating systems features and develop applications for a their own or a provided Xinu operating system can be outlined to one similar to the one below. The example course layout has the listed applied assignments as well as several written assignments of problems developed with the textbook in mind or taken from the textbook.

Student Extended Xinu

2010-03-01T18:10:54Z

Akoehler: /* Course Outcomes */

[[Category:Teaching With Xinu]]
[[Category:Student Extended Xinu]]
== Overview ==
Having students integrate advanced operating systems features and develop applications for a their own or a provided [[Xinu]] operating system is one of the potential tracks presented for a professor that is [[Teaching With Xinu]].

Students will learn to extend an operating system by adding kernel level and user level applications. Given a functional Embedded Xinu operating system the students will have to understand and manipulate existing operating system code to create additional operating system features. To add more applications to the operating system students will have to understand the interactions between the program in design and the operating system's device and kernel interaction calls. Programming for embedded devices allows students to engage in development on small resource constrained environments. Through extending the existing Embedded Xinu operating system a student learns to use and understand code not written by the student and develops advanced operating system concepts.

== Course Outcomes ==
Course development can parallel learning objectives and topics associated with many Communication and Networking courses. [[Student Built Xinu#References|[1]]]

=== Topics ===
* Overview of operating systems
* Operating system principles
* Concurrency
* Scheduling and dispatch
* Memory management
* Device management
* Security and protection
* File systems
* Evaluating system performance

=== Learning Objectives ===
* Intimate knowledge of embedded devices.
* Overview of the general and specific purpose of an operating system.
* Understanding concurrency and state flow diagrams.
* Understanding deadlock and starvation.
* Understanding the use of memory and virtual memory.
* Characteristics of serial and parallel devices.

Akoehler: /* Spring 2010 */

* KT: [after using a configure script that accidentally made a directory named ~] I was trying to remove the ~ directory. I tried ''rm -r ~'' and the system complained about files in use. I thought that was weird, so I used the ''-f'' force option [resulting in ''rm -rf ~'']. When I tried to use ''make'', it said file not found and that is when I realized I deleted my home directory.

Akoehler: /* Spring 2010 */

== Spring 2010 ==

* KT: [after using a configure script that accidentally made a directory named ~] I was trying to remove the ~ directory. I tried ''rm -r ~'' and the system complained about files in use. I thought that was weird, so I used the ''-f'' force option [resulting in ''rm -rf ~'']. When I went to ''make'' the system I was using it said file not found and that is when I realized I deleted my home directory.

Akoehler: /* Letter received August 31, 2009 */

==== Letter received August 31, 2009 ====
I'd just like to say thanks for making your xinu wiki pages available on the web. I have found them
useful (particularly the example of using CFE to boot over the network, which is suggested in the CFE
functional spec, but which I haven't seen documented anywhere else).

Reading about xinu makes me wish that I was back in school (attended decades ago).

anyway, thanks again. 
robert
