formation, the Security Working Group took over project governance of (Open Portable Trusted Execution Environment), initially a proprietary TEE project developed by ST-Ericsson. In May 2014, Linaro launched the Linaro Digital Home Group, focused on ARM-based media gateways and STBs (Set Top Boxes). A few months later in July 2014, the Linaro Consumer Group (formerly known as the Linaro Mobile Group) was formed to consolidate and optimize open source software for mobile platforms on ARM. In 2015, Linaro launched 96Boards, a specification created with the aim of delivering compatible low cost, small footprint 32-bit and 64-bit Cortex-A boards. In 2016, Linaro launched the Linaro IoT and Embedded Group, with the aim of developing “end-to-end open source reference software for IoT devices and applications.” In 2018, Linaro restructured the engineering groups to align with the technological landscape. As a result, the Linaro Networking Group and the Linaro Digital Home Group were both disbanded and the Linaro Edge & Fog Computing Group created. In 2019, Li Gong was appointed Linaro CEO. In 2022, Linaro launched the Windows on Arm Group together with Arm, Microsoft and Qualcomm. Engineering Activities Core Technologies Linaro's Core Engineering Team is focused on co-maintaining the ARM ecosystem. The team works directly with upstream projects supporting core technologies including Linux kernel core features, power management, security, toolchain support (both GCC and LLVM), testing and CI and Virtualization. It makes regular public releases along with a number of reference builds of kernels and userspace for various Linux distributions (including Android and Ubuntu) on member SoCs. The Core Engineering team also maintains the automated testing system called LAVA (Linaro Automated Validation Architecture) which Linaro developed. LAVA is for automated testing of the open source components that are used in the major Linux-based software platforms. A lab running LAVA and a wide variety of ARM hardware is run for the use of Linaro and member company engineers. Segment specific engineering The remaining work done by Linaro is split into groups focusing on particular markets where ARM processors are used. These include: Linaro Datacenter & Cloud Group The Linaro Datacenter & Cloud Group focuses on Linux development for ARM servers. The team's mission is to bring competing companies together to work on common solutions to problems and enable OEM's, commercial Linux providers and System on Chip (SOC) vendors to collaborate in a neutral environment on the development of the core software needed by
