Linux系统下如何用C/C++语言编写程序查看cpu_id的值

Question

难道没有高人么？我就不信 ，+50分

Answer 1

#include <stdio.h>
static inline void native_cpuid(unsigned int *eax, unsigned int *ebx,
unsigned int *ecx, unsigned int *edx)
{
/* ecx is often an input as well as an output. */
asm volatile("cpuid"
: "=a" (*eax),
"=b" (*ebx),
"=c" (*ecx),
"=d" (*edx)
: "0" (*eax), "2" (*ecx));
}

int main(int argc, char **argv)
{
unsigned eax, ebx, ecx, edx;

eax = 1; /* processor info and feature bits */ native_cpuid(&eax, &ebx, &ecx, &edx);
printf("stepping %d\n", eax & 0xF);
printf("model %d\n", (eax >> 4) & 0xF);
printf("family %d\n", (eax >> 8) & 0xF);
printf("processor type %d\n", (eax >> 12) & 0x3);
printf("extended model %d\n", (eax >> 16) & 0xF);
printf("extended family %d\n", (eax >> 20) & 0xFF);
}

在linux当然是GNU编译器工具
C语言的GCC;
