A technique to enable secure application and data integrity within a computer system. In one embodiment, one or more secure enclaves are established in which an application and data may be stored and executed.

Method and apparatus to provide secure application execution

A method of and apparatus for communicating between a host and an agent. The method includes the step of performing a first transaction between a host controller and a hub. The hub is operable to perform a single transaction with an agent based on the first transaction. The method then includes the step of performing a second transaction between the host controller and the hub. The second transaction is based on the single transaction.

Split transaction protocol for a bus system

Embodiments of apparatuses, methods for partitioning systems, and partitionable and partitioned systems are disclosed. In one embodiment, a system includes processors and a partition manager. The partition manager is to allocate a subset of the processors to a first partition and another subset of the processors to a second partition. The first partition is to execute first operating system level software and the second partition is to execute second operating system level software.

System partitioning to present software as platform level functionality via inter-partition bridge including reversible mode logic to switch between initialization, configuration, and execution mode

Security arrangements for a universal serial bus (USB) protocol stack of a USB host system are provided. The security arrangements prevent an unauthorized or suspicious USB device from communicating with the host system, detect suspicious activity originating from a device which is already communicating with the host system and may provide notification to a user.

Security arrangements for extended USB protocol stack of a USB host system

Embodiments of apparatuses, methods for partitioning systems, and partitionable and partitioned systems are disclosed. In one embodiment, a system includes processors and a partition manager. The partition manager is to allocate a subset of the processors to a first partition and another subset of the processors to a second partition. The first partition is to execute first operating system level software and the second partition is to execute second operating system level software. The first operating system level software is to manage the processors in the first partition as resources individually accessible to the first operating system level software, and the second operating system level software is to manage the processors in the second partition as resources individually accessible to the second operating system level software. The partition manager is also to present the second partition, including the second operating system level software, to the first operating system level software as platform level functionality embedded in the system.

System partitioning to present software as platform level functionality including mode logic to maintain and enforce partitioning in first and configure partitioning in second mode

In one embodiment, the present invention includes a method for allocating at least one dedicated core and at least one shareable core to a first partition of a system, where the cores are owned by the first partition. During operation, the shareable core(s) may be made dynamically available for use in one or more other partitions of the system, while the first partition retains ownership of the shared core(s). Other embodiments are described and claimed.

Sharing resources of a partitioned system

Briefly, in accordance with an embodiment of the invention, an apparatus and method to store initialization and configuration information is provided. The method may include storing basic input/output system (BIOS) software in a polymer memory. The method may further include copying a first portion of the BIOS software from the polymer memory to a random access memory (RAM) buffer of a memory controller, wherein the RAM buffer has a storage capacity of at least about two kilobytes (KB).

Method and apparatus to store initialization and configuration information

Embodiments of apparatuses, methods, and systems for partitioning memory mapped device configuration space are disclosed. In one embodiment, an apparatus includes a configuration space address storage location, an access map storage location, and addressing logic. The configuration space address storage location is to store a pointer to a memory region to which transactions to configure devices in a partition of a partitioned system are addressed. The access map storage location is to store an access map or a pointer to an access map. The addressing logic is to use the access map to determine whether a configuration transaction from a processor to one of the devices is to be allowed.
