At the core of ARM64 driver support is the Linux kernel. Unlike x86 architecture where hardware is often automatically discovered, ARM64 relies heavily on blobs. The driver for a specific component (like Wi-Fi or the Display) is useless without the corresponding Device Tree node that tells the kernel where the hardware physically lives in memory and what interrupts it uses.
