Optimising GCC performance for RISC-V
Optimising GCC performance for RISC-V We have delved into compiler optimisations and their impact on performance, specifically focusing on the GCC toolchain and its code generation for RISC-V. This work is conducted as a collaboration between BayLibre and Rivos and sponsored as part of the RISE Project. It is centered around the SPEC CPU 2017 […]
Maintaining the Yocto Project: Monitoring Recipes with AUH
Introduction Yocto Project maintenance frequently involves upgrading many recipes in a layer to a more recent upstream version. The benefits of doing so include pulling in bugfixes, new features and tests, retaining compatibility with other packages, and so on. Manually, this might be done with six or seven main steps as follows: Determine the appropriate […]

Android bootflow: experiments with U-Boot and GBL
Booting Android is fairly different from traditional Linux distributions. There are multiple partitions involved, the bootloader needs to pick a boot slot and decide which boot mode will be used. Because of this, Android has specific bootloader requirements. The AOSP documentation gives an overview of these. In this blog post, we will explore how to […]
