AutumnOS: RISC-V version

Originally started as a general OS research on r/osdev, AutumnOS has undergone a significant architectural pivot to meet the demands of modern mobile computing. To achieve maximum hardware compatibility, security, and a rich application ecosystem, the project has been rebuilt as a Linux-based Mobile Operating System. ​By transitioning from a custom microkernel approach to a highly optimized Linux kernel, AutumnOS now leverages advanced process management, robust networking stacks, and extensive driver support. Targeting RISC-V mobile platforms, AutumnOS aims to provide a seamless, open-source mobile experience that bridges the gap between lightweight hardware and handheld efficiency.

• Michael Scott on weather clock widget
• Gravity 0 (floating icons on home page)
