Do It Faster: How We Supercharged Linux To Work With Blazing Fast ADCs for IIO - Trevor Gamblin, BayLibre

Wednesday August 27, 2025 09:00 - 09:40 CEST

Elicium 1

What does it take to support high-performance ADCs and DACs in the kernel? To get the most out of these devices, we need to make some significant overhauls to PWM and SPI subsystems, including adding pivotal new features such as SPI offload and PWM waveform to the upstream Linux kernel. This has ultimately led to adding support for dozens of ADC/DAC devices in the IIO subsystem and expanded the capabilities of those already there, allowing them to operate up to millions of samples per second without jitter. We'll give a high-level overview of how this project came about, the target hardware configurations, test equipment used, and methods to make it all happen, along with the challenges we overcame in the process. A "lessons learned" approach to this review and some possibilities for future work will round out the talk.

From Raw To Refined: The Evolution of Raw Flash Support in Linux - Miquèl Raynal, Bootlin

Wednesday August 27, 2025 09:50 - 10:30 CEST

Elicium 1

The Memory Technology Device (MTD) subsystem has come a long way from its early days of rudimentary flash support. As embedded systems have evolved, so too has Linux’s ability to manage and interface with raw flash memory devices — from parallel NAND and NOR to modern SPI-based variants.

While SPI NOR initially led the charge, the past few years have seen SPI NAND support in Linux grow rapidly, gaining robustness, better performance, and broader compatibility. But the story doesn't end there. Improvements across the MTD stack continue to shape how developers design with raw flash.

This talk takes a tour through the evolution of raw flash support in Linux: how we got here, what’s new, and what it means for future designs. Whether you’re maintaining legacy NAND systems or eyeing SPI NAND for your next embedded project, we’ll explore the practical impact of recent changes and what to expect next. Raw flashes might not be dead just yet — they’ve just gotten smarter.

Unified Boot Time Measurement: A Precise, Scalable Framework for Multi-Processor Systems - Vishnu Pratap Singh & Soumya Tripathy, Texas Instruments

Wednesday August 27, 2025 11:00 - 11:40 CEST

Elicium 1

This session introduces a unified boot time measurement framework that overcomes these limitations. Inspired by U-Boot’s bootstage mechanism, it leverages hardware timers to generate synchronized timestamps across heterogeneous subsystems. Instead of relying on fragmented logs, the framework writes boot markers to a reserved DDR memory region, enabling a Linux utility to extract and analyze the complete boot timeline via the devmem interface. This approach ensures end-to-end visibility, enabling developers to pinpoint inefficiencies, optimize boot sequences, and improve system responsiveness.

With the increasing complexity of embedded devices—ranging from IoT and industrial automation to automotive and networking—achieving fast and predictable boot times is more important than ever. This talk provides a vendor-agnostic, software-based approach to measuring and optimizing boot performance, benefiting developers working on custom Linux BSPs, embedded RTOS systems, and real-time applications.

How To Support Multiple Display Controllers With Different Interfaces on One SoC - Devarsh Thakkar, Texas Instruments & Aradhya Bhatia, Intel Corporation

Wednesday August 27, 2025 11:55 - 12:35 CEST

Elicium 1

Modern SoCs often integrate multiple display controllers to support advanced use-cases such as multi-display setups, content mirroring, or screen extension. These controllers typically support heterogeneous interfaces like DSI, HDMI, OLDI, or (e)DP to accommodate a wide range of panels and bridge devices. Taking TI’s AM62P SoC as an example-which includes two display controllers, a GPU, and multiple interfaces such as DSI, DPI/HDMI, and OLDI-this talk will cover the design considerations involved in enabling Linux DRM driver support for such systems. It will explore two key approaches for supporting multiple controllers: integrating both under a single DRM card versus exposing them as 2x separate DRM cards, along with their pros and cons. The talk will also highlight the architectural changes made to support dual OLDI bridges multiplexed between controllers, allowing either configurations–dual-link (from a single controller) or 2x single-link (from separate controllers). Finally, it will discuss the challenges with DSI bridge integration, particularly around crtc-encoder-bridge operation sequences, and how bridge APIs can be used to support custom sequences for bridge operations.

Advancing AI Application Development on RISC-V Platforms - Yuning Liang, DeepComputing

Wednesday August 27, 2025 14:10 - 14:50 CEST

Elicium 1

RISC-V has made significant strides as an open instruction set architecture for embedded, edge, and server-class systems. However, enabling modern AI workloads: such as speech-to-text, LLM inference, and multimodal generation on RISC-V remains a major technical challenge, particularly in resource-constrained environments.

In this session, we share our ongoing efforts to enable real-world AI applications on RISC-V platforms based on a 64-bit 8-core RISC-V AI SoC. We explore the porting, optimization, and runtime behavior of popular open-source AI workloads like Whisper, VLC with Speech-to-Text, webLLM, and text-to-image generation, running entirely on RISC-V hardware.

We will also discuss the implications of DSP instruction emulation for RISC-V vector standard RVV 1.0, as well as the use of Vector DSP and Vulkan and OpenCL backends, and how developers can contribute to or replicate these experiments. Our goal is to provide a transparent, reproducible pathway for the open-source community to extend AI capabilities on emerging RISC-V platforms.

Feasibility and Architecture of a Dual-Board Embedded System: Yocto & Zephyr Integration - Andrea Ricchi & Dario Binacchi, Amarula Solutions

Wednesday August 27, 2025 15:05 - 15:45 CEST

Elicium 1

In this presentation, we provide an in-depth look at our experience conducting an industrial feasibility study focused on a dual-board embedded system designed for communication over CAN bus. The system architecture consists of two boards, each with distinct operating environments. The primary board runs a Linux-based system that leverages Flutter for a responsive graphical user interface, while the secondary board operates on Zephyr RTOS, utilizing LVGL to deliver lightweight graphical functionality.

We walk through the complete development lifecycle of this system, beginning with hardware selection and bring-up, progressing through board support package (BSP) development, device tree configuration, and peripheral driver integration. We also discuss the differences in system architecture between Linux and Zephyr. We then analyze Flutter and LVGL, evaluating their suitability for embedded UI development, performance trade-offs, and integration strategies.

Attendees will gain practical insights into designing and evaluating industrial embedded systems while overcoming the challenges of multi-platform development and integration.

Enhancing Interrupt Controller Reliability: Implementing Error Detection Correction in Linux - Priyadarsini G, Samsung Semiconductor India Research, Bangalore

Wednesday August 27, 2025 16:20 - 17:00 CEST

Elicium 1

Error Detection and Correction (EDAC) is critical for ensuring data integrity and system reliability, particularly in modern high-performance computing architectures. ARM’s Generic Interrupt Controller is widely used in multi-core processors design, where fault tolerance is essential for maintaining system stability. With the rising risk of transient and permanent faults due to hardware aging, radiation effects, and environmental interference, integrating EDAC mechanisms into interrupt controller is essential for preventing data corruption and unexpected system failures.

This work presents the first implementation of EDAC for ARM GIC-600 interrupt controller in Linux kernel, extending EDAC subsystem with new patches and drivers to integrate ARM’s error-reporting capabilities. The talk explores the necessity of EDAC in mitigating errors in interrupt controller and includes sample code snippets demonstrating how to extend the Linux EDAC framework to support error logging and correction.

Furthermore, we present performance benchmarks and case studies evaluating the effectiveness of EDAC in interrupt controller, highlighting trade-offs between error resilience and system overhead.
