Re: how to disable vm exit on cpuid 0x00 ?

how i understand this bug not fixable end cannot be disable ?

whay the vm exit is forsed when it's try call cpu id ?

if it's not call cpu id all good - its happen only how you see on comet of code if

move aex 0x00

cpuid

this code work fine no detect's vmware ( if change cpuid.x.xxx"xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx")

static inline unsigned long long rdtsc_diff() {

  unsigned long long ret, ret2;

  unsigned eax, edx;

  __asm__ volatile("rdtsc" : "=a" (eax), "=d" (edx));

  ret  = ((unsigned long long)eax) | (((unsigned long long)edx) << 32);

  __asm__ volatile("rdtsc" : "=a" (eax), "=d" (edx));

  ret2  = ((unsigned long long)eax) | (((unsigned long long)edx) << 32);

  return ret2 - ret;

}
