Domains

Domains are isolated components in AlienOS. Each domain is a separate Rust project that can be loaded/unloaded/update at runtime. Domains can be categorized into three types: Common, Fs, and Driver.

• Common domains are used to provide common functionalities, such as syscall, memory, and process management.
• Fs domains are used to provide file system functionalities, such as devfs, dynfs, ramfs, fat-vfs, and domainfs.
• Driver domains are used to provide device driver functionalities, such as uart8250, virtio-net, visionfive2-sd, plic, and rtc.

See AlienOS to know how to load/unload/update a domain.
