Sets the global interrupt flag.

void __svm_stgi(void);


The __svm_stgi function is equivalent to the STGI machine instruction. The global interrupt flag determines whether the microprocessor ignores, postpones, or handles interrupts due to events such as an I/O completion, a hardware temperature alert, or a debug exception.

This function supports the interaction of a host's virtual machine monitor with a guest operating system and its applications.
