__svm_skinit

Microsoft Specific

Initiates the loading of verifiably secure software, such as a virtual machine monitor.

void __svm_skinit(
   int SLB
);

Parameter

Description

SLB

The 32-bit physical address of a 64K byte Secure Loader Block (SLB).

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, and protects components from tampering by interrupts, device access, or another program if the computer is a multiprocessor.

The SLB 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 that establishes the operating environment for the computer, and subsequently loads the security kernel.

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