Linux Kernel
Linaro employs a significant number of maintainers covering a wide range of important areas. This allows us to reach far within open source communities and have a real impact.
We actively contribute to the upstream community and help facilitate acceptance of Linaro code into the Linux mainline kernel. Our ultimate goal is to ensure kernel consolidation - a single source tree with integrated support for multiple Arm SoCs and Arm-based platforms.
We manage and implement support of new features not only dedicated to Arm architecture but also covering core functionalities of the kernel. In the tradition of Linux and the open source community, much of the technical discussion takes place over email and informal conversations on IRC.
Linaro Projects focused on the Linux Kernel
Power and Performance
Over the years devices have become more compact and powerful yet batteries are more constrained. Linaro’s Performance Project aims to improve the efficiency of all Arm based Linux systems by improving Linux subsystems such as the scheduler, thermal framework and traditional power management subsystems. These subsystems influence performance of power consumption and help systems use power budget efficiently while reaching maximum performance. This prevents systems from overheating and crashing.

SoC have shared and critical resources which are usually handled by a dedicated and secured power coprocessor (SCP). This dedicated processor is in charge of gathering requirements of the different subsystem/clients. However, some systems cannot afford a dedicated processor or do not have enough client channel for all possible subsystems. In such cases, an SCMI server must be able to run a different Execution environment than the usual cortex M bare metal. This Linaro project addresses those use cases.
