What's wrong with this (in GCC):

ULONG CPUID_Result=0;
asm ("movl $1,%%eax;cpuid;"
:"=a"(CPUID_Result)
: //Ingen input!
:"%eax","%ebx","%ecx","%edx");

All I want to do is call CPUID with EAX=1 and have to result stored in
CPUID_Result!

Solved it:

Code: Select all

           ULONG CPUID_Result=0;   
           asm ("movl $1,%%eax;cpuid;"
           :"=a"(CPUID_Result)
           : //Ingen input!
           :"%ebx","%ecx","%edx");
