    摘要: A mechanism is provided, in a data processing system, for accessing memory based on an effective address submitted by a process of a partition. The mechanism may translate the effective address into a virtual address using a segment look-aside buffer. The mechanism may further translate the virtual address into a partition real address using a page table. Moreover, the mechanism may translate the partition real address into a system real address using a logical partition real memory map for the partition. The system real address may then be used to access the memory.

    摘要: A secure computer architecture is provided. With this architecture, data is received, in a component of an integrated circuit chip implementing the secure computer architecture, for transmission across a data communication link. The data is converted, by the component, to one or more first fixed length frames. The one or more first fixed length frames are then transmitted, by the component, on the data communication link in a continuous stream of frames. The continuous stream of frames includes one or more second fixed length frames generated when no data is available for inclusion in the frames of the continuous stream.

    摘要: A mechanism is provided for performing secure recursive virtualization of a computer system. A portion of memory is allocated by a virtual machine monitor (VMM) or an operating system (OS) to a new domain. An initial program for the new domain is loaded into the portion of memory. Secure recursive virtualization firmware (SVF) in the data processing system is called to request that the new domain be generated. A determination is made as to whether the call is from a privileged domain or a non-privileged domain. Responsive to the request being from a privileged domain, all access to the new domain is removed from any other domain in the data processing system. Responsive to receiving an indication that the new domain has been generated, an execution of the initial program is scheduled.
