Two Linux pioneers, David Rusling (Linaro) and Linus Torvalds (Linux Foundation) will chat about past, present and future of Linux and the Open Source community. Questions submitted before hand will also be answered. Question submittal information coming soon.
Continuing the discussion from Linaro Connect Bangkok 2016, we discuss further experiments with Window Assisted Load Tracking (WALT, formerly WinLT) on other architectures such as x86 and with different workloads including laptop/desktop and server usecases. We propose that WALT is more accurate in tracking cpu/task utilization than PELT (which we believe is better at load rather than util tracking) and that better utilization estimation schemes can be built on top of WALT. Experiments use the new schedutil governor. Examination of individual use cases in detail as well as how to handle migration and potential caveats of a windowing scheme are discussed.

★ Session Summary ★
96Boards will be hosting Openhours live from Linaro Connect! Join us in person or remotely to talk about all things 96Boards related.
Time Sensitive Networking (TSN) is a set of protocols and extensions that allow precise control of traffic latencies over standard Ethernet and is of growing importance in Automotive, Industrial, and Professional Audio/Video domains. This talk provides an overview of the topic and will include a dialog to help set priorities and next steps for work in this area with other interested groups.
ARM Trusted Firmware has established itself as a key part of the ARMv8-A software stack. Broadening its applicability across all segments, from embedded to enterprise, is challenging. This session discusses the latest developments, including extension into the 32-bit space.
The presentation will look at the ways in which GDB can be enhanced when debugging the Linux kernel to give it better knowledge of the underlying operating system to enable a better debugging experience. It will also provide a status of the current work being undertaken in this area by the ST landing team, a demo and potential future work.
You may think OpenDataPlane and DPDK are somewhat equivalent. But they are not. OpenDataPlane is about Software Defined Dataplanes while DPDK is a Software Dataplane. A Software Defined Dataplane can control a hardware only Dataplane in a way that packets can go from input port to output port without reaching a CPU core. With Software Dataplanes , all packets have to reach a CPU core. As a result, one vendor could leverage a Software Defined Dataplane to build a 100Tbps network box while it is not possible with a Software Dataplane.
