At the recent RISC-V Summit, Lars Bergstrom, Google’s director of Android engineering, said in a keynote that Google wants RISC-V to be a T1-level support architecture for Android — that is, at the same level as ARM processors. This statement shows that Google’s support for the RISC-V open source instruction set architecture has changed dramatically. Bergstrom said half a year ago that it would take a lot of work to optimize the Android version for RISC-V, and he outlined a roadmap that would take years to bear fruit. However, Android’s support for RISC-V is accelerating. In September last year, the Android Open Source Project (AOSP) project began to add official RISC-V patches. Now anyone can try the riscv64 branch of Android. Bergstrom promised initial emulator support for RISC-V early this year, and Android RunTime (ART) support for Java workloads in the first quarter. Google’s increased support for RISC-V may have something to do with ARM’s instability over the past few years. ARM’s parent company, Softbank, tried to sell it to Nvidia, but after that failed, it was preparing to take the company public. At the same time, ARM is still in a lawsuit with its largest customer, Qualcomm, and ARM China has a lot of problems.
