Google’s Generic Kernel Image now required on all Android form factors

New TVs that launch with Android TV 14 or later on Linux kernel 5.15 or higher will be required to meet Google’s Generic Kernel Image (GKI) requirements in order to pass certification!

This means that GKI is now enforced on all major Android form factors with AArch64 chipsets: handhelds, watches, automotive, & televisions.

What this means is that all the major Android form factors will be running kernels that adhere to the GKI requirements, which means SoC and board support is not part of the core kernel, but instead achieved through loadable modules. This should, in theory, make it easier to provide long-term support.
