Which ARM64 disassembler engine best to use in a driver?

[sh3dow]

Capstone would be the most complete, battle proved and standalone disassembler framework that doesn't need to be part of other software to function. it's disassembly/disassembler framework that just works.

Also from its website

- Special support for embedding into firmware or OS kernel.

Capstone is designed to be able to easily embed into firmware & OS kernel. The framework can be built to be minimized, and with some special APIs provided by Capstone, the engine can be programmed to use in those special environments. Details are available here.

- reliable [✓]
- lightweight [I don't know, it's it's a framework and support multiple architectures not just ARM64]
- free ARM64 disassembler engine [✓]

Edit:
It look like you can build only selected architectures to suite your need, so lightweight [✓] I guess?
