CPUID is an X86 instruction: http://en.wikipedia.org/wiki/CPUID used to
get information about the CPU. The Core performance counter extensions
is mentioned on the wikipedia page.
You'll need to write assembly code to use this instruction or use
cpuid.h. Here is an example of using this instruction from a previous
answer on this list:
#include <cpuid.h>
#include <stdio.h>
int main()
{
unsigned a, b, c, d;
/* check __get_cpuid_max here */
__cpuid(10, a, b, c, d);
printf("eax: %x ebx %x ecx %x edx %x\n", a, b, c, d);
int i;
for (i = 0; i < 10; i++)
if (b & (1 << i))
printf("event %d not supported\n", i);
return 0;
}
