The CLGI instruction clears the GIF (global interrupt flag). While the GIF is cleared, external interupts are disabled.

This instruction is a Secure Virtual Machine (SVM) instruction. If SVM is disabled, execution of this instruction will raise a #UD exception.

public void CLGI()
{
    if (!SVM.Enabled)
        #UD;
    GIF = 0;
}
