librtpi: Conditional Variables for Real-Time Applications

Presenter:Gratian Crisan, National Instruments

Linux on Quick Turnaround Projects at Ball: No, We Aren't Putting Linux in Canning Jars

Presenter:Sam Povllus, Ball Aerospace
Summary:This Presentation will focus on the aspects of making Linux work with an FPGA,
as well as how various hardware and software decisions were reached and how those decisions affected
aspects of integration with hardware, and maintenance.

Steering Xenomai into the Real-Time Linux Future

Presenter:Jan Kiszka, Siemens AG
Summary: we will present our plans and first steps to revive the Xenomai community, make it broader and stronger.
This involves scaling down the project scope to a maintainable core.

Maintaining a Real Time Stable Kernel

Presenter:Steven Rostedt, VMware
Summary: This slides will present what is required to maintain a stable RT tree, such as tools that you can use.
What tricks can be done with git to find properly backport patches that are RT specific. It will also cover
the current tests that are performed to make sure the released RT stable kernel is fully functional.

What Every Driver Developer Should Know about RT

Presenter:Julia Cartwright, National Instruments
Summary: The intent of this presentation is to describe the classes of problems in drivers which have detrimental impact
to RT, why they cause issues on RT, and how they might be resolved.

Not Really, but Kind of Real Time Linux

Presenter:Sandra Capri, Ambient Sensors
Summary: This slides will illustrate what kernel configurations worked, and how kernel space code compared to user space code.
Additionally, there may be other ways to skin this real time cat. Results will be reported from work done on a Raspberry Pi
as well as a BeagleBone Black.

CPU Power Saving Methods for Real-time Workloads

Presenter:Ramesh Thomas, Intel
Summary: The presentation will give a background of the issues faced by real-time applications when CPU power management is enabled.
It will then explain tools, configurations and methods that can be used to tune applications and CPU power management in the
kernel to be able to save power without impacting the deterministic latency tolerance requirements.

Effectively Measure and Reduce Kernel Latencies for Real-time Contraints)

Presenter:Jim Huang, South Star Xelerator (SSX)
Summary: This presentation provides the information of the effective ways to experiment the different methods, in terms of
their response latency, and figure out how the system load, and user space task priorities affect them on both Intel and
ARM architectures.Also discussed about how to analyze and improve the scalability of Linux performance in multi-core
environments upon the measurements, used in actual real-time applications.

Building Mixed Criticality Linux Systems with the Jailhouse Hypervisor

Presenter:Ralf Ramsauer, Technical University of Applied Sciences Regegnsburg
Summary: This presentation provides the information about porting a safety and real-time critical existing application as
a Jailhouse guest. It shows a novel and promising approach for implementing mixed-criticality applications with real-time
requirement while not loosing the benefits of Linux.Also information about a multicopter platform running the real-time
critical flight stack in an isolated Jailhouse guest.

Timekeeping in the Linux Kernel

Presenter:Stephen Boyd, Qualcomm Innovation Center
Summary: This presentation provides information about timekeeping code, exploring how the kernel abstracts the hardware,
how those abstractions are built upon to implement NOHZ, timers, hrtimers, cpu-idle, POSIX clocks, etc.
and how we keep things working when these abstractions break down with the tick-broadcast mechanism.

Real-Time Linux on Embedded Multicore Processors

Presenter:Andreas Ehmanns, Technical Advidor
Summary: This presentation gives idea about vanilla kernel and describes real-time multicore system. Based on tests
running on a 8-core and a 24-core hardware system presenter discuss each single step, it's effect on real-time
behaviour and explain why profound processor architecure knowledge is mandatory.

OpenEmbedded in the Real World

Presenter:Scott Murray, Konsulko Group
Summary: This presentation provides information about implementing OpenEmbedded in a production build system and issues associated
with shipping and maintaining an OpenEmbedded based product.Also describes building OpenEmbedded based distributions for both
small and large customers to discuss some of the common pitfalls encountered and pragmatic workarounds for them

Power Management in Zephyr RTOS

Presenter:Ramesh Thomas, Intel
Summary: The presentation will give an overview on the power management infrastructure provided by Zephyr.

Understanding a Real-Time System

Presenter:Steven Rostedt, Red Hat
Summary: This presentation provides information about different aspects of Real-Time system such as hardware and
firmware, followed by the kernel, the libraries used, and special constraints for applications and the interaction
between these levels.

Practical Real-Time Linux

Presenter:Arnout Vandecappelle, Essensium/Mind

Using Real-Time Patch with LTSI Kernel

Presenter:Yoshitake Kobayashi, Toshiba
Summary: This presentation shows requirement and issues to make LTSI-RT patch.

Using and Understanding the Real-Time Cyclictest Benchmark

Presenter:Frank Rowand, Sony Network Entertainment
Summary: This talk explore and explain the complexities of Cyclictest. Also provides information
about how Cyclictest describe potential real-time performance of a system.

Understanding PREEMPT_RT (The Real-Time Patch

Presenter:Steven Rostedt, RedHat
Summary: This talk will explain what the real time patch provides and special programming tips that will
ensure embedded developers will get the best from their devices.

Common Clock Framework: How to Use It

Presenter:Gregory Clement, Free Electrons
Summary: This presentation provides an introduction on why we needed Common clock framework and on the
problems it solves, the implementation details of this framework. And describes how to use this framework to
add clock support to a new ARM SoC.

Making Linux do Hard Real-Time

Presenter:Brent Roman, Monterey Bay Aquarium Research Institute
Summary: This presentation gives information about Real-time system along with practical examples.
