Embedded Open-Source Upstreaming: Linux Kernel, Zephyr, AOSP, Lineage & Beyond
Silicon Signals advances open-source innovation through upstreaming embedded and mobile technologies, contributing kernel patches, RTOS enhancements, and community-driven code as trusted reviewers and maintainers.
We deliver upstreaming solutions for NXP i.MX, Qualcomm, TI Sitara, STM32, Amlogic, Allwinner, and Rockchip platforms. Our expertise spans cameras, sensors, displays, power drivers, memory, V4L2, IIO, DRM, ISP, ALSA, Media, USB, Networking, and power management, all CI-tested and community-reviewed.
Real code. Real impact. We deliver intelligent, maintainable upstream solutions bridging hardware and software.
Our work on Linux, Zephyr, AOSP, and U-Boot shows how dedicated we are to open-source excellence. We make sure that our embedded solutions work well, are stable, and are easy to maintain on all platforms.
We are building the right code. The right way.
We deliver reliable upstream solutions through Linux kernel, RTOS, and open-source expertise—building maintainable, future-ready software that boosts performance, scalability, and aligns with community standards.
Active participation in open-source ecosystems, building reputation through collaboration.
Successfully integrated drivers and features into projects, ensuring sustained long-term impact.
Trusted kernel maintainers enforcing quality, compliance, and rigorous integration standards.
Deep expertise across Linux kernel, Zephyr OS, and more, delivering tailored custom solutions.
Expert knowledge of GPL, MIT, Apache, BSD licenses ensuring complete legal code compliance.
Expert integration of cameras, sensors, displays, power, media and networking.
Upstreaming refers to contributing code, drivers, and enhancements directly to open-source projects like the Linux kernel, Zephyr, AOSP, or U-Boot. This ensures long-term maintainability, reduced technical debt, and standardized support across platforms.
Upstreaming reduces maintenance overhead, avoids repeated rebase efforts with every update, ensures community validation, and improves long-term software stability.
We support NXP i.MX, TI Sitara, Qualcomm, Rockchip, Intel, Amlogic, STM32, and NVIDIA platforms, along with custom board bring-up and subsystem integration.
Yes. We work across V4L2, DRM/KMS, ALSA, IIO, USB, Networking, Power Management, Memory, and Sensor subsystems for embedded and mobile devices.
Absolutely. We contribute to AOSP frameworks, HAL layers, vendor interfaces, multimedia stacks, and device-tree configurations for custom Android-based systems.
Yes. We develop Zephyr-based BSPs, scheduler-level optimizations, peripheral drivers, IPC communication, and real-time task performance enhancements.
Yes. We implement board bring-up, memory initialization, secure boot flows, SPL/TF-A integration, and submit patches to maintainers for long-term support.
