__svm_skinit
Microsoft Specific
Initiates the loading of verifiably secure software, such as a virtual machine monitor.
Syntax
void __svm_skinit(
int block_address
);
Parameters
block_address
The 32-bit physical address of a 64K byte Secure Loader Block (SLB).
Remarks
The __svm_skinit function is equivalent to the SKINIT machine instruction. This function is part of a security system that uses the processor and a Trusted Platform Module (TPM), to verify and load trusted software, called a security kernel (SK). A virtual machine monitor is an example of a security kernel. The security system verifies program components loaded during the initialization process. It protects components from tampering by interrupts, device access, or another program if the computer is a multiprocessor.
The block_address parameter specifies the physical address of a 64K block of memory called the Secure Loader Block (SLB). The SLB contains a program called the secure loader. It establishes the operating environment for the computer, and then loads the security kernel.
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.
