Pre-requisites: QNX Neutrino RTOS Architecture, Building a Boot Image
Learn how to use the QNX Adaptive Partitioning Scheduler, or APS, to group threads and/or processes into partitions according to their CPU requirements and/or to protect them from CPU starvation. APS is useful for safety and/or hypervisor related products or any product where partitioning the CPU may be needed. We will discuss the architecture of APS, how to add APS to an image, define and understand partitions, critical priorities and bankruptcy. There are hands-on exercises to explore administering APS from both the command line and with the APS API.
Learn how to use the application profiler in the QNX® Momentics® Tool Suite to profile a single process. Using the profiler, you can pinpoint which parts of your code are consuming the most CPU, at both the function level and the source-line level. You can then use that information to make your code more efficient. Both live and postmortem profiling are covered.
A detailed look at building boot images, which contain the binaries that run just after the reset vector. Boot images typically include components such as startup code, the process manager, the kernel, drivers, and a startup script. We also explore various ways to load a boot image onto your target.
Determining the effectiveness of a test suite takes work. In this section we'll see the IDE tools determining how much of your code has actually been executed, broken down to the source line, by your testing.
A quick look at the relative advantages and disadvantages of the various IPC methods supported by QNX with a few to choosing which method(s) to use in your system.
This section provides a quick introduction to editing, compiling, running, and debugging your application from the QNX Momentics IDE, giving the minimum needed to do the programming exercises in the programming sections.
Note: This module is a light replacement for the Editing and Compiling and Running and Debugging modules. If you take one of those modules, it isn't necessary to take this one.
Memory problems, such as memory corruption, can often be subtle and uncaught by testing. In this section, we explore the powerful Momentics IDE tools for finding memory corruption, leaks, and excessive memory consumption.
This section will focus on the code editor in the Momentics IDE, including the many powerful, time-saving features. In addition, we look at how to build code and how the IDE identifies problems with the build.

Prerequisites: Threads and Synchronization, Introduction to Resource Managers
Explores the various ways to return from handlers, manage access and modification times, leave clients blocked, use multi-threaded resource managers, implement combine messages, perform unblock handling, receive pulses, and make select() and ionotify() work. Resource manager concepts are reinforced through a variety of hands-on exercises.
Prerequisites: QNX Neutrino RTOS Architecture
We start with how QNX architecture lends itself to high availability, then look at how to design applications that take advantage of that architecture. Next, we explore the high availability toolkit in detail, starting with how to use the high availability manager for doing process restart and multistage restart. We then cover the client recovery library, also included in the toolkit, which helps clients to restore broken connections.
Focussing on Eclipse fundamentals, this section provides the background that anyone working with the IDE in the QNX Momentics Tool Suite must have. Starting with the central concepts of the IDE, you'll become adept at navigation in the IDE and configuring it to suit your personal needs and likes. We then talk about projects, workspaces and the host-target model, introducing various ways to interface to your target. We end with a handful of preferences that can make your life easier.
Prerequisites: Threads and Synchronization
Explores the various methods that the QNX Neutrino RTOS provides for allowing two or more processes to exchange information and control. We focus on the QNX message passing that is fundamental to how QNX Neutrino works, but also examine pulses, shared memory and QNX Persistent Publish/Subscribe Service.
Prerequisites: Interprocess Communication (recommended)
Explores how the QNX Neutrino RTOS makes it relatively easy to write and debug interrupt handlers. We present several approaches to interrupt handlers.
An introduction to hardware access methods including IO-mapped and memory-mapped IO, allocating DMA-safe memory, and interrupt handling.
An overview of port I/O, memory mapped I/O, DMA memory configuration, and how to use the PCI API.
Prerequisites: Interprocess Communication
Any process can be a resource manager, and drivers usually are. This section looks at the capabilities of resource managers, including pathname-space resolution, IPC message formats, and general structure. Through a set of exercises we'll look at the initialization of a simple resource manager and the handling of read() and write() operations.
Covers in detail the I/O aspects of a driver, including how to do port I/O and memory-mapped I/O, how to perform DMA memory configuration, and how to use the PCI API. Note: If you take this module, you don't have to take the "Introduction to I/O" module.
Prerequisites: I/O, Introduction to Resource Managers
A collection of challenging exercises that are a must for anyone learning to write device drivers. The exercises used depend on the hardware available. You can choose from:
- VGA Text Mode driver exercise (2.5 hours)
You'll write an I/O manager that does read()s from, write()s to, and devctl()s for changing the configuration of VGA text mode memory.
- Keyboard driver exercise (1.5 hours)
You will write a simple driver that handles x86 keyboard input.
The basic container for code in the IDE is a project. We cover the three types of projects for C/C++ code: a project where the entire contents and build structure are up to you, a project with a predefined structure that supports multiple platforms, and library projects. We cover both header file and project dependencies and discuss how to get code from elsewhere and place it into your projects.
Prerequisites: Threads and Synchronization
Covers additional issues for anyone who wants to know a lot about threads, including reader/writer locks, once control, and thread local storage.
QNX also supplies a rich set of POSIX IPC methods. This section looks at signals, shared memory, pipes, POSIX message queues, and TCP/IP.
Provides the background that anyone working with the IDE in the QNX Momentics Tool Suite must have. Starting with the central concepts of the IDE, you'll become adept at navigating in the IDE and configuring it to suit your personal needs. We then talk about projects, workspaces, and the host-target model, introducing the various ways to interface with your target. We end with a handful of the preferences that can make your life easier, along with pointers to various sources of documentation.
Gives an overview of the QNX Neutrino RTOS architecture, covering what the microkernel and the process manager do. We talk about standards, protected address spaces, process/thread model, timing, and scheduling. We also introduce various types of IPC, synchronization, what a resource manager is and where shared objects fit in.
