Wednesday 23 January

09:00 - 09:45 Conference Wide Plenary Session -- Jamie Lewis (CEO - The Burton Group) -- See Main Agenda

09:45 - 10:00 Introduction to the Real-time and Embedded Systems Forum
This session includes a brief forum status update.

10:00 - 10:30 Liaison Reports -- SAE, OMG, IEEE PASC SSWG-RT, NCITS, WSTAWG, RTAG
This session is for liaisons to the Real-time and Embedded Systems Forum to report on their status in a series of brief slots (maximum of 5 minutes per report).

10:30 - 15:00 Special session on Real-time Linux
The Linux Special Interest Group has a series of sessions looking at aspects of Real-time Linux

Session title: Real-Time Capability for Native Linux -- Kevin Morgan, MontaVista Software

Modern real-time requirements for systems requiring a full function operating environment such as Linux can now be met with Linux. Enhancements in kernel attributes such as fixed overhead real-time process scheduling, characterization and tuning of maximum interrupt off paths, general preemptibility of the Linux kernel, and the continued migration of I/O driver processing to schedulable kernel threads are transforming the Linux kernel into a highly capable real-time operating environment. In this talk these capabilities are overviewed, their current state is outlined, and the future of native real-time in Linux is discussed.

Session title: Applications That Require a Real-time Linux Variant -- Steve Brosky, Concurrent Computer Corp

The standard Linux kernel, as defined by kernel.org, cannot be classified as a real-time operating system. One approach to using Linux in real-time systems is RTLinux. This kernel architecture implements a separate real-time executive as the primary operating system, which in turn runs a standard Linux kernel when there are no high priority tasks ready to be run. This approach has the advantage of being able to guarantee very good interrupt response times while requiring only minimal changes to standard Linux. For many applications in the real-time space, this approach provides exactly the kinds of capabilities required. This presentation will present examples of some real-time applications whose needs cannot be satisfied by the RTLinux approach. These applications fit into a classification that I will term "complex real-time applications". The needs of complex real-time applications are best met by making modifications to standard Linux for implementing real-time functionality and some level of deterministic behavior. This presentation will also examine some of the capabilities that are required by this class of application.

Session title: High Resolution POSIX Timers for Embedded Linux -- John Mehaffey, MontaVista Software

Embedded systems often require more precision in the timing and sequencing of events than can be provided by the standard 10 millisecond timebase provided by standard Linux. Currently, more precise delays are provided by delay() or nanosleep(), which do busy-waiting in the kernel. Busy waiting is wasteful of CPU resources which could be put to better use while waiting for external events or delays.

This presentation will examine the High Resolution POSIX timer feature for Linux, which uses hardware features of modern architectures to provide timer resolution down to the microsecond level using the Programmable Interrupt Timer.

12:45 - 13: 30 Lunch

13:30 - 14:15 Application Design Impact of CPU and Network Reservations in Linux - Doug Locke, TimeSys Corporation

Many embedded applications have performance requirements that include hard or soft bounds on response time. Providing full RTOS capabilities in Linux is critical to such applications, including kernel preemptibility, good priority management, control over interrupt priorities, priority inheritance, high resolution clocks and timers. In practical applications, however, performance issues are often not so simple. Real applications have bursty event arrivals, they use multiple application components with different performance attributes (e.g., X Windows), and they frequently experience transient overloads. While such requirements can be addressed in some ad-hoc ways, reservation technology provides an entirely new approach to application design that makes such applications much easier to design, implement, and maintain. This presentation will discuss the application of CPU reservations and Network reservations to several application domains, illustrating how to achieve highly predictable performance, regardless of load, in Linux.

14:15 - 15:00 Moving Linux to the Enterprise -- Next Generation POSIX threads, Bill Abt et al, IBM

At 15:00 the session splits into two parallel tracks

15:00 - 15:45 Real-time and Embedded Profiles
Jim Oblinger and Joe Gwinn will give a presentation on the current status of the POSIX profiling work.

15:45 - 16:00 Break

16:00 - 17:30 Real-time and Embedded Profiles Working Group session -- Joe Gwinn et al.

15:00 - 17:30 Parallel Session -- Safety Critical

This session runs in parallel, and is chaired by David Emery with guest speakers John Chilenski and Leslie Johnson. Dave Emery will give a presentation on the status of activities to include an overview of a draft Safety Critical White Paper (comments on the white paper are welcomed to david.emery@opengroup.org). John Chilenski will address challenges of DO-178B software certifcation for the Boeing 777. Leslie Johnson will address the Military Transition to DO-178B Certification.
