__svm_stgi

Microsoft Specific

Sets the global interrupt flag.

Syntax

void __svm_stgi(void);

Remarks

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. For more information, search for "AMD64 Architecture Programmer's Manual Volume 2: System Programming," at the AMD corporation site.
