Progress in Porting Android onto RISC-V: Testing, Performance and Open Source
summary
Alibaba T-Head runs Android 12 on RISC‑V with multimedia, camera, Wi‑Fi/Bluetooth and NN support; AOSP upstreaming begins in September with Google merging patches. CTS shows roughly 13% tests passing and VTS has ~20 tests green while many failures trace to missing hardware or third‑party libraries. A remote cloud lab exposes real boards for automated unit and system regression. Optimizations (hand assembly and vectorized memcpy, ART/JIT tweaks, FP math) yield ~13% to 20% speedups and cut an image decode from 100 ms to 5 ms. ~80 patches submitted, ~half accepted; ~80 contributors across 20 organizations.
