Real-time and Embedded Forum announces Jan. 23-25 agenda

Dec 14, 2001 — by LinuxDevices Staff — from the LinuxDevices Archive — views

The Open Group has issued the agenda for the January Real-time and Embedded Systems forum meeting . . .

Agenda Version 1.0 — Subject to Change

The Real-time and Embedded Systems Forum will meet Wednesday January 3rd through to Friday January 25th.

Sessions to be held in Anaheim include the second annual meeting of the Linux Special Interest Group, which looks at issues related to Real-time Linux. Sam Bowser and Robert Allen will lead the Security session, which will be focusing on the recent Request for Information issued by the group. Dave Emery, forum co-chair will lead a session on Safety Critical software. Joe Gwinn, chair of the PASC SSWG-RT committee, will give a presentation looking forward beyond the current POSIX 1003.13 profiles. There will be a continuation of the discussions on Hard Real-time Java, led by Glen Logan and Robert Allen. Short status updates from Liaisons to the forum are expected from the US Army WSTAWG, DoD RTAG, OMG, SAE and IEEE PASC SSWG-RT.

The PASC SSWG-RT committee is also meeting co-located with the Forum during the week of the conference. Details of their agenda are at http://www.pasc.org/SSWG-RT. Attendees of the PASC SSWG-RT are welcome to attend the Forum sessions.

The session schedules follow below

    Wednesday

    9:00 – 9:45 Conference Wide Plenary Session — See Main Agenda

    9:45 – 10:00 Introduction to the Real-time and Embedded Systems Forum
    This session includes a brief forum status update.

    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 – 11:00 Break

    11:00 – 12:30 RT 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.

    Session: to be confirmed
    Speaker: Next Generation POSIX Threads for Linux

    13:00 – 14: 00 Lunch

    14:00 – 15:30 Real-time and Embedded Profiles

    Joe Gwinn will give a presentation on the current status of the POSIX
    profiling work. There will also be a working session of the profiles
    working group on the Thursday afternoon between 14:15-17:30.
