AOSP on Taped-Out RISC-V SoC Without RVA22/23 - I Came Back to Finish Ruinland

Explore the technical challenges and solutions for running Android Open Source Project (AOSP) on a real silicon RISC-V test chip platform that predates the RVA22/23 profiles. Learn from ChuanTzu Tsai's journey across multiple companies to achieve this goal, including his work at Andes Technology and SiFive before returning to complete the project on the Qilai platform. Discover the specific modifications and workarounds required to adapt AOSP for older RISC-V hardware that lacks the extensions Google now requires for their Cuttlefish platform. Examine whether all the modern RISC-V extensions are truly necessary for running Android, and understand the practical considerations involved in porting Android to legacy RISC-V silicon. Gain insights into the real-world economic and technical evaluation challenges faced when bringing Android to RISC-V platforms, along with the showcase results demonstrated at various RISC-V conventions.
