An increasing number of vendors are including TSN support on their hardware. There’s a great diversity in the ecosystem for configuring switches and their respective features as many vendors rely on out-of-tree modules and home-grown user-space tools. Adding switchdev capable drivers for switches gives us a common way of configuring NICs and switches using common user-space netlink-based tools

LVC20-201 Boot-Time Tracing With Extra Boot ConfigFriday, October 16, 2020
Boot-time tracing is one of the latest Linux kernel tracing proposal, which allows us to trace kernel booting with full tracing features, like per-event filters and triggers, histograms, instances, dynamic-events etc. Along with the boot-time tracing the kernel command-line interface is also expanded by Extra Boot Config (XBC) so that user can specify complex boot-time settings with structured-key value configuration file.
This talk will show you what the boot-time tracing and the extra boot config provide, the advantages and how you can use it for your boot-time features.
LVC20-317 Analysis of ARM64's Competence for Oil&Gas Seismic Data Processing ApplicationsWednesday, September 30, 2020
Each seismic survey in Oil & Gas exploration generates tons of seismic wave data, typically hundreds of Terabytes. Transforming the huge amount of data into a accurate earth subsurface model requires exascale level computing power. This presentation will analyze the computing requirements and trends in seismic data processing, evaluate the competence of the current generations ARM64 SoCs and the new features required.
LVC20-117 Everything you want to know about live migration on Arm64 CloudWednesday, September 30, 2020
Slack channel to chat with the speaker during the live broadcast: https://linaroconnect.slack.com/archives/C01B1SV18F5
Currently, one big gap between Arm64 and X86 cloud platforms is that X86 can provide a much better instance migration experience than the Arm64 platform. CPU comparison and CPU model capabilities have provided Arm64 VM with the ability to live migration among different hardware vendors. This function is the essential function of the data center. From the cloud management framework, we also need to consider the realization of supporting VM live migration.
In this session, we will talk about what we have done in the most widely used virtualization management tool - Libvirt to provide better live migration capabilities on Arm64 platform and also some details in the newest lightweight cloud management project such as Kubevirt.
With live migration support on Arm64, it can finally benefit the cloud ecosystem for large scale datacenter scenarios which may use different Arm64 CPU architectures and vendors.
SAN19-510 - Is Chromium OS favorable for IOT Devices ?Friday, October 4, 2019
Getting electronic devices onto internet and well connected with each other hasnt been a trivial task for the engineering community, always challenged by end price of the product, software scalability from devices running firmware to complex devices running complete OS distro, lack of fine tuned libraries and framework to introduce security of data, over the air upgrade and configuration and calibration of devices, supporting both head and headless units. Though the industry met the end user demand and floating requirements in time, the challenges continue to exist for next generation devices
where the focus is on integrating multiple key components like
security, networking, graphics, AI and ML libraries and sensor control frameworks into one singe device. While solving the system integration requirements is a key thing the other equal important aspect of ensuring the software is maintained for bug fixes, long term supported, simultaneous support for multiple SOCs and controllers is very much essential.
The end equipment manufacturers have various software options to chose from and each have their own advantages and disadvantages, inbuilt features and support infrastructure. Chromium OS is one of the latest open source software distributions maintained by Google for almost a
decade now has made its way into IOT segments.
In this session we look into the key components in Chromium OS that can help us overcome the software challenges in building next generation IOT devices.
- Chromium OS is initially designed for laptops, desktops and stand alone / all inone boxes, the well integrated software components like browsers, networking, security, boot options and window management can be leveraged as is for IOT devices. We go through few of these components to understand if they meet the IOT requirements.
- Chromium OS is built on Linux, thereby the OS has support for multiple latest SOCs and device drivers for various controllers. We should be discussing if chromium OS has picked up all the latest trends in Linux OS related to Power Management, security, upgraded device driver frameworks, etc.
- In general IOT devices are headless or less UI centric, we explore if chromium OS can be easily configured to boot on a headless unit ?
- Understanding the system requirements, memory requirements and power utilization are few key factors to consider if the OS fits the budget available for the end equipment.
- The new set of IOT devices are now pre-integrated with AI algorithms to help end user for better understanding of the surrounding or indecision making etc. The devices are also self learning with ML algorithms. Its important to know if Chromium OS has frameworks to download AI/ML algorithms or firmware at run time on DSPs or SOCs. Also ensure if there are HALs and APIs to exchange data to/from DSPs or SOCs running AI/ML algorithms.
The topics covered in this session should help us quickly assess if chromium os is favorable for IOT devices or if we were bringing an elephant in the room.
BKK19-300K2 - KEYNOTE: Attack of the Millennial I.T. Buyer Hardware at Software Speed in the Age of GitHubTuesday, April 16, 2019
The emergence of a new Enterprise buyer aligns with a number of other shifts that are reshaping our $1 trillion technology ecosystem: the move to a disaggregated architecture, a rise in developer power, the growing influence of open source, and massive investments in silicon, data centers, and wireless. This talk will explore the opportunities and risks, and why ecosystem chops are more important than ever.
