Shifting to software-first in Automotive on Arm

ADAS/AD Workload Use Case: Find the balance between lock-in solution and OSS

We help you find the right balance by embracing Open Source Software (OSS) with confidence. Our role is to provide the quantitative evidence you need to make the best architectural decisions.

Our independent benchmarking services compare the real-time performance of your options:

• Proprietary RTOS (your current or considered solution
• Real-Time Automotive Grade Linux (RT/AGL)
• Android Automotive.

Make well-informed design decisions based on data, not just vendor claims. Drive your ADAS/AD strategy with confidence and control.

Achieving Performance and Efficiency through Compact Linux and MRAM

Safety critical and time sensitive requirements in automotive systems demand an operating system that can satisfy hard real time constraints. Linaro has a long track record of working with the Linux kernel and as such, knows how best to leverage linux for automotive use cases where there are regulatory safety requirements.

We believe integrating Magnetoresistive random-access memory (MRAM) into the SoC is the most powerful way to enhance performance and energy efficiency (by establishing a near-memory computing structure in AUTOSAR’s classic or adaptive compute platforms). MRAM, as non-volatile memory, provides fast read and write speeds (comparable to SRAM in read operation), low power consumption and the ability to retain data even when power is lost.

Cyber Security for Automotive: OS Long-Term Support for Compliance

New global regulations have turned software maintenance from a 'best practice' into a legal requirement. Regulations like UNECE WP.29 R155/R156 (for cybersecurity and software updates) and the EU Cyber Resilience Act (CRA) mandate that automakers must be able to provide security updates for the entire lifecycle of the vehicle (10 ~ 15 years).

Unsupported Automotive OS (eg. AAOS and AGL kernel, and other OSS components) with EOL (end-of-life) makes it extremely difficult and legally risky to comply with these mandates. Automakers must prove to regulators that they have a robust process for managing vulnerabilities for many years, which is nearly impossible without a long-term supported foundation.

With decades of experience in kernel upstream and kernel functional testing (LKFT), Linaro has been trusted by the world's leading semiconductor companies as their LTS (long-term support) and OSS “All-In-Upstream Strategy” partner in the Arm open-source ecosystem.

Working with Linaro enables automakers to: Maintain a Hardened LTS Kernel: 

• Provide a stable, secure, and continuously updated Linux kernel specifically for automotive use cases.
• Maintain the Core AOSP Userspace: Backport critical security and stability fixes to the core Android components long after Google's official support ends.
• Access proactive CVE Monitoring to help them meet their regulatory obligations : Actively monitoring security databases for vulnerabilities relevant to the automaker's software stack.
• Validate Patches:  Develop, test, and provide high-quality patches for the LTS kernel and AAOS, leveraging Linaro’s world-class CI/CD highly scalable infrastructure (LAVA & ONELab) - ensuring that every update is robust and reliable.
• Access Compliance Artifacts: Provide the documentation and evidence needed to demonstrate compliance with UNECE R155/R156 and the CRA."

Unlocking the True Power of Automotive HPC: Bridge Performance Gaps with OSS software Stacks on HPC

Linaro focuses on software and architecture optimization to fully exploit and utilize the capabilities of your HPC automotive hardware. Working with Linaro allows you to:

• Maximize Performance: Tune your software stack to extract every ounce of power from your silicon.
• Run Mixed-Criticality Safely:  Efficiently and safely combine IVI infotainment and safety-critical functions (ASIL) on a single HPC or chiplet.
• Guarantee Freedom From Interference(FFI): Implement robust, certifiable isolation using hypervisors, containers, or discrete safety islands to meet the strictest standards.

Standardizing device access through Virtio

How do you enable virtualized components to communicate to one another without standard interfaces? This is the challenge Linaro intends to solve through VirtIO.

VirtIO is an OASIS specification which describes how hardware devices are discovered, managed and accessed in virtual environments. Those hardware devices are then presented to guest operating systems as virtual devices, also known as virtio-devices.

The benefit of following the virtio-device specification is that it stops you from being locked in with a vendor, giving you the possibility to write driver implementations that are independent of architecture and operating system.
