vmbase
For VMs running under crosvm on aarch64, the vmbase library provides a linker script and useful defaults for the build rules, along with an entry point, UART console logging and more.
#![no_main] #![no_std] use vmbase::{main, println}; main!(main); pub fn main(arg0: u64, arg1: u64, arg2: u64, arg3: u64) { println!("Hello world"); }
main!
宏用于标记需从vmbase
入口点调用的 main 函数。vmbase
入口点用于处理控制台初始化,并在 main 函数返回时发送 PSCI_SYSTEM_OFF 命令以关闭虚拟机。
