Why Won't My CPU Sleep? Debugging CPUIdle Mysteries on ARM SoCs - Dhruva Gole, Texas Instruments India Ltd & Kevin Hilman, BayLibre, Inc.

Monday August 25, 2025 09:00 - 09:40 CEST

Elicium 1

Linux power management has relied on CPUIdle to transition CPUs into low-power states for a long time. More recently, suspend-to-idle (s2idle) was added which relies heavily on the CPUidle infrastructure to support system-wide suspend & resume using low-power idle states.

On modern Arm SoCs, deeper idle states can shut down not just the CPU, but also local per-CPU timers, interrupt controllers and peripherals, sometimes leading to unexpected entry-exit failures, scheduling delays, and even system hangs.
Debugging such issues can be complex since common debug methods may not be available in low-power modes and because the kernel, platform-specific firmware and dedicated hardware all interact to enable low-power modes. Therefore, debugging requires a good understanding of the CPUIdle internals, PSCI firmware interactions and wakeup timer behavior.

Through real-world case studies, attendees will learn how to trace idle state transitions, identify CPU wakeup failures, ARM Trusted Firmware's PSCI framework internals and apply effective debugging strategies to ensure correct working of the CPUIdle framework on their ARM Linux systems.

TPM Is No Silver Bullet: Pitfalls in Embedded Device Security - David Gstir, sigma star gmbh

Monday August 25, 2025 09:55 - 10:35 CEST

Elicium 1

With the growing adoption of TPMs (Trusted Platform Modules) in the Linux ecosystem, thanks to features like TPM-backed disk encryption in systemd and the longstanding use in Windows BitLocker, TPM chips are seeing a resurgence as a go-to for secure secret storage. This trend is increasingly making its way into embedded devices. Often as a measure to fulfill NIS2, EU Cyber Resilience Act or similar requirements.

However, embedded systems present a vastly different threat model compared to desktops or servers, and TPMs often don’t deliver the level of security many developers assume. In this talk, David will demystify TPM functionality in embedded Linux environments. He will give a concise overview of security threats for embedded devices and where a TPM can and or where it cannot. Special focus will be put on using TPMs for disk encryption and integrity.

The session will wrap up with a discussion of alternative approaches, other usage scenarios for TPMs, and how to make informed decisions when designing secure embedded systems.

Clocking Strategies in the Linux Kernel: Optimizing Power and Performance in High-End SoCs - Varada Pavani & Bala Naveena Nivetha M, Samsung Semiconductor India Research

Monday August 25, 2025 11:20 - 12:00 CEST

Elicium 1

Modern System-on-Chips (SoCs) are designed for a wide range of applications, including mobile devices, automotive systems, AI accelerators, and data servers. As SoCs become more powerful with increasing core counts, heterogeneous architectures, higher clock speeds, and enhanced AI processing capabilities, power consumption also rises. This increased power demand introduces challenges such as heat dissipation, battery life, clock management complexity and system reliability. In this talk, we explore various techniques to optimize power consumption and enhance performance using Common Clock Framework (CCF) in the Linux kernel.

We begin by discussing the role of clock management in Linux and covers various clocking strategies available in CCF to achieve optimal power and performance. Topics include dynamic clock scaling, disabling unused clocks, efficient parent clock selection and the notifier mechanism. We also explore clock usage monitoring in Linux through debugging tools such as clk_summary and kernel tracing.

Overall, this talk demonstrates how effective clocking strategies in the Linux kernel can significantly improve power efficiency and system performance in high-end SoCs.

Graphic Testing Without Hardware: Discovering the Power of VKMS! - Louis Chauvet, Bootlin

Monday August 25, 2025 15:35 - 16:15 CEST

Elicium 1

As a userspace developer, creating graphical applications is a common task. While software and frameworks like Weston or Qt make it straightforward to display content on a screen, ensuring compatibility across various displays poses significant challenges. Users may have different screen sizes, resolutions, and capabilities, making comprehensive testing complex. How will your application perform on a small screen? What about an extremely large one? How does it react to displays being connected/disconnected? Moreover, if your application must run on diverse devices, how will it leverage or adapt to varying hardware capabilities?

VKMS addresses these challenges by enabling graphic testing without the need for physical hardware. VKMS is a Linux kernel DRM driver that allows you to emulate a wide range of display configurations on any device. This talk will introduce VKMS, highlight its current capabilities, demonstrate practical test examples, and provide details on additional features we are currently working on upstreaming into VKMS.

ESSTRA: A Software Suite To Enhance Software Transparency and Traceability in Software Supply Chain - Takuya Namae, Sony Group Corporation

Monday August 25, 2025 16:30 - 17:10 CEST

Elicium 1

When you use OSS, do you want to know which source files are compiled and included in the binaries? Project ESSTRA (https://github.com/sony/esstra) is a tool that collects a list of source files while compiling your software and embeds the data into the binaries.

Recently, the importance of using SBOMs has been increasing, and there is a growing demand for improved transparency and traceability in the software supply chain from the perspectives of vulnerability management and OSS license compliance. However, it is difficult to trace the details of which files are included in the binaries used in your product or service, and which OSS licenses to comply with based on this data.

To solve this issue, Sony has developed ESSTRA. It is available now as open source itself, and includes both a GCC plugin to record source files during a build and embed it into resulting binaries, as well as a tool to manage the information.

ESSTRA is already supported by Binary Analysis Next Generation (BANG) tool.

Attendees of this session will learn how to use ESSTRA and take the first steps to improve the transparency and traceability of your project's software.

How V4L2 Transformed To Support Embedded Cameras - Laurent Pinchart, Ideas on Board

Tuesday August 26, 2025 11:00 - 11:40 CEST

Elicium 1

Cameras in today's embedded devices are made of increasingly complex hardware. The V4L2 API has constantly evolved since its birth nearly 25 years ago to support the needs of this ever-changing landscape. What has however not changed much is the impression that V4L2 is the same today as it was 10 years ago, and that it can't adapt to modern devices.

This talk will rectify this misconception by presenting all the recent features of the V4L2 API relevant to cameras in embedded systems. We will cover raw image sensors with complex processing features (such as HDR or NPU), streams multiplexing, powerful ISPs, complex pipelines of serializers and deserializers, multi-context image processing, and more. Examples will focus not just on wishful thinking for the future, but on open solutions that are developed and ship today.

Attendees will see how to support embedded cameras on Linux with mainline kernels and without closed-source stacks, learn which APIs they need for their use cases and how to use them, and hear about ongoing V4L2 developments and where the API is heading for the future.

Bridging Worlds: Using Device Tree Overlays To Support Complex PCI Devices in Linux - Hervé Codina, Bootlin

Tuesday August 26, 2025 11:55 - 12:35 CEST

Elicium 1

To support complex PCI devices, a new solution landed in Linux kernel (v6.13). It allows to describe hardware within a PCI device using a Device Tree (DT) overlay, taking advantages of the DT such as modularity, clarity, and wide driver support.

The Linux kernel provides a rich set of drivers for hardware blocks found in System-on-Chips (SoC). These drivers typically rely on DT descriptions. Some of those blocks appear in PCI devices. Instead of adapting drivers to the PCI context, why not having PCI devices working in a DT context?

The first driver using this feature is the driver for the Microchip LAN966x PCI device. The LAN966x SoC was already supported in the kernel, with Linux running on its ARM cores. Drivers exist for all its hardware blocks. The PCI device version is made from the SoC version where CPU cores have been replaced by a PCI endpoint. Using a DT overlay for PCI devices allows to reuse existing drivers without any modification.

This talk will delve into motivations and use cases behind this feature, followed by a dive into the implementation. We will present challenges encountered, how they were addressed, and what this means for future PCI device support.

Tuesday August 26, 2025 14:10 - 14:50 CEST

Elicium 1

More and more industrial products are being designed with add-on components that can be hotplugged at runtime and connected with non-discoverable busses: I²C, MIPI CSI-2, LVDS, and seemingly simpler ones such as interrupts and GPIO lines.

Work is in progress for the kernel to support such hardware using device tree overlays. This talk describes the goals, work done and in progress and future directions. Special attention will be given to the DRM subsystem which is by far the most challenging one.

Topics covered are:

* Problem statement and overview of the goals

* Non-discoverable hotplug in general: device tree overlays and how to properly describe connectors and

add-ons (nexus nodes, export-symbols), instantiating devices, I²C bus issues

* DRM specific: hotplugging in the DRM subsystems, challenges in making DRM bridges removable, current work and next steps

Discussion about future directions will be very welcome.

Lightning Talk: Reliable Recovery in Partitioned Embedded Systems Using IVSHMEM and Jailhouse Hypervisor - Paresh Bhagat, Texas Instruments

Tuesday August 26, 2025 16:20 - 16:30 CEST

Elicium 1

In industrial and real-time embedded environments, system uptime and fault recovery are mission critical. This proposal explores a lightweight and effective technique for crash detection and recovery using Inter-VM Shared Memory (IVSHMEM) within the Jailhouse hypervisor. By continuously sharing heartbeat or health status between the root cell and inmate (guest OS) via shared memory, the system can quickly detect unresponsive partitions and trigger recovery mechanisms like automated restarts without a full system reboot. We demonstrate this approach on TI SITARA EVMs, showing how it minimizes downtime without a full system reboot. Through this talk, I aim to share a reusable pattern for enhancing system reliability and show how open-source virtualization can be leveraged for resilient industrial applications. Attendees will gain insights into partitioned system design, shared memory communication, and recovery strategies for embedded systems. I hope to receive feedback on enhancing this approach and hear from others solving similar reliability challenges in embedded systems.

Tuning Linux for Embedded Space Applications - Simon Corbin, CNES

Tuesday August 26, 2025 16:40 - 16:50 CEST

Elicium 1

Space is a hostile world, requiring many precautions to be taken when embedding software in a spacecraft. Historically, this results in hardware targets embedding chips that are qualified and tolerant to the environment (radiation in particular), but rather old, expensive and produced in small batches.

The expansion of “New Space” has democratized the use of COTS, considerably increasing available onboard computing power and opening up new ways of embedding applications in satellites.

While it can be tedious to port an application onboard (limited to C language, restricted memory and computing power, limited user community...), using Linux minimizes the effort involved in porting an algorithm onboard. However, the world of on-board space applications requires compliance with numerous rules and standards. This presentation aims to provide an overview of the challenges involved in using Linux onboard a space system.

The aim is to give an overview of how we make embedded software at CNES and how Linux can take us to new dimensions. The following topics will be discussed regarding embedded Linux for space applications :

- Real time aspects

- Reliability

- Processes segregation

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.

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.

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.
