• The full overview of available RISC-V Ubuntu images is available at https://ubuntu.com/download/risc-v.

• Android (AOSP)

• Google is Landing ART patches for switch interpreter: almost done

• Google will upstream T-Head’s patches in AOSP/ART and later separate into standalone repo. Cao Xia (from ESWIN) sent an alternative patch https://r.android.com/2457968, but Google wants to proceed with T-Head’s work as they have a full compiler implementation based on that.
