Notes

Abstract

Android support for RISC-V is advancing rapidly, and this talk delivers an in-depth technical update on the open-source AOSP porting effort. We will walk through the current status of AOSP on RISC-V platforms, including ART/LLVM, Bionic, HAL and vendor-interface development, and compatibility work for emerging RISC-V SoCs. The session will examine the key engineering challenges encountered along the way—such as JIT/AOT differences on RISC-V, graphics-stack porting (Mesa, DRM/KMS, GPU drivers), GSI support, SELinux policy bring-up, vendor_boot and dynamic-partition layout, and end-to-end boot-flow integration. We will also highlight upstream contributions completed so far, the remaining gaps in the AOSP tree, and the milestones required to achieve full device bring-up and CTS/VTS compliance. Attendees will come away with a clear understanding of the progress to date and concrete opportunities for community collaboration to accelerate a fully open, fully native Android ecosystem for RISC-V devices.

Yuning Liang

Yuning Liang is the Founder and CEO of DeepComputing, focusing on developing innovative technology products based on RISC-V SoMs. From the world's first RISC-V development laptop DC-ROMA to pads, workstations, remote-controlled cars, drones, and more, all are based on RISC-V chips. The world's first RISC-V laptop, the world's first RISC-V pad capable of making phone calls, and so on, are all Yuning's masterpieces. Yuning's innovation and pioneering spirit in the RISC-V field have enabled him to create several world firsts, leading DeepComputing to gain widespread recognition in the global RISC-V product commercialization field, contributing significantly to the advancement and progress of RISC-V technology. Yuning's career has taken him from the UK to Switzerland, then to South Korea, and finally to China. He has a strong practical background in embedded systems, platform APIs, and system software. In 2024, he was honored with the "RISC-V Community Contributor Award" and recognized as a "Ubuntu Summit Contributor," further solidifying his influence in the technology sector.
