IT Home reported on April 30 that Google announced at the beginning of 2023 that it would bring RISC-V architecture support to the Android system. However, the latest news is that the project has suffered a major setback, and Google's Android Common Kernel (ACK) is about to remove support for the RISC-V architecture.
Google's senior engineer in charge of the core branch of Android Linux submitted a series of patches to AOSP showing "removed ACK support for riscv64". The description of these patches states that "support for the risc64 GKI kernel has been discontinued".
IT之家注：ACK 全称是 Android Common Kernel，是谷歌维护的官方 kernel.org Linux 内核下游分支。
The ACK is basically a Linux kernel with patches of interest to the Android community, but has not yet been incorporated into the mainline or long-term support (LTS) kernel.
Since ACK removed support for RISC-V, companies and institutions that want to compile Android RISC-V versions immediately will need to create and maintain their own Linux branches to facilitate further integration of RISC-V patches.
A Google spokesperson then said:
RISC-V will continue to be supported on Android. Due to the speed of iteration, we are not yet ready to provide a unified support image for all vendors. We've removed the relevant patches that support RISC-V from the Android Generic Kernel Image (GKI).
