在Windows中使用汇编获得CPU ID

use std::arch::asm;

fn main(){
    let mut a: u32 = 0; //eax
    let mut d: u32 = 0; //edx

    unsafe {
        asm!( 
        "mov edi, ebx",
         "cpuid",
         "xchg edi, ebx",
         in("eax") 1,
         lateout("eax") a,
         out("edx") d,
        )
    }

    let hex = format!("{:08X}{:08X}", d, a);
    println!{"{}", hex};
}

结果
