摘要： The initialization of a computer system including a secure execution mode-capable processor includes storing a secure operating system code segment loader to a plurality of locations corresponding to a particular range of addresses within a system memory. The method also includes executing a security initialization instruction. Executing the security initialization instruction may cause several operations to be performed including transmitting a start transaction including a base address of the particular range of addresses. In addition, executing the security instruction may also cause another operation to be performed including retrieving the secure operating system code segment loader from the system memory and transmitting the secure operating system code segment loader for validation as a plurality of data transactions.

摘要： A computer system includes a processor which may initialize a secure execution mode by executing a security initialization instruction. Further, the processor may operate in the secure execution mode by executing a secure operating system code segment. The computer system also includes an input/output (I/O) interface coupled to the processor via an I/O link. The I/O interface may receive transactions performed as a result of the execution of the security initialization instruction. The transactions include at least a portion of the secure operating system code segment. The I/O interface may also determine whether the processor is a source of the transactions. The computer system further includes a security services processor coupled to the I/O interface via a peripheral bus. The I/O interface may convey the transactions to the security services processor dependent upon determining that the processor is the source of the transactions.

摘要： A method of controlling access to an address translation data structure of a computer system. The computer system includes a processor having a normal execution mode and a secure execution mode. The method includes executing code and generating a linear address. During translation of the linear address into a physical address, the method also includes generating a read-only page fault exception during the normal execution mode in response to detecting a software invoked write access to an address translation data structure having a read/write attribute set to be read-only. The method further includes selectively generating either the read-only page fault exception or a security exception during the secure execution mode in response to detecting the software invoked write access.

The system may include a crypto-processor and a memory coupled to receive memory transactions through the crypto-processor. The memory transactions are passed to the memory by the crypto-processor. The system may include a first processor, a second processor coupled to the first processor, and a storage device operably coupled to the first processor through the second processor. The second processor is configured to control access to the storage device. The method includes transmitting a request for a memory transaction for a storage location in the storage device and receiving the request for the memory transaction at the crypto-processor.
