I am using a free ARM (aarch64) compute instance from Oracle Cloud as a development machine. I would like to compile an Kernel for my Android phone (arm64), but I'm having trouble with selecting the appropriate toolchain.
Google provides Android-specific toolchains, *aarch64-linux-android-* and *arm-linux-androideabi-*, but these are primarily distributed for x86_64 hosts. After a couple of hours of searching the internet, I found mentions that I could use the host (or native) compiler for my system, which happens to be *aarch64-linux-gnu-* and *arm-linux-gnueabi-*. However, these toolchains target a generic Linux environment, and I'm not sure if they would be suitable for compiling a kernel for an Android device. I'm particularly concerned about potential optimization issues or compatibility problems that might arise from using these toolchains. Questions: 1. Is it appropriate to use the generic Linux toolchains (**-linux-gnu-*) for compiling an Android kernel? 2. What's the recommended approach to build the Android-specific toolchains (**-linux-android-*) on an aarch64 host? I am having difficulty finding answers on my own and would appreciate detailed explanations.
