Linux drivers are considered legacy on Android, all new drivers should follow the Project Treble architecture, which is basically the genesis of how Fuchsia drivers work.
Every driver has their own process and uses Android IPC to talk with the kernel.
The stable ABI is Android HIDL, similar to Fuchsia FIDL, a protocol buffer based IPC for fast communication with the kernel, that also allows for passing references to hardware buffers across processes.
