Re: how to get privilege (x86)?
Read the manual on conforming and non-conforming segments, then for a 32-bit kernel, try SS instead. Then when you're done, get rid of the code because there's absolutely no need to have it.

On some platform there is a simple API for applications:
/troll
Code: Select all
bool IsRing3(void) {
return true;
}
