Abstract: Embodiments of the invention provide a novel and non-obvious method, system and computer program product for securing of leased resources on a computer. In one embodiment of the invention, a computer for securing resources may comprise at least one processor, a plurality of resources, wherein each resource is associated with configuration data and a programmable logic device connected to each of the plurality of resources. The programmable logic device may be configured for determining whether a resource is leased, reading un-encoded configuration data from a resource, and sending the configuration data to a first unit, if the resource is not leased. The programmable logic device may further be configured for reading encoded configuration data from a resource, decoding the configuration data, sending the configuration data that was decoded to a first unit, and logging use of the resource by the first unit, if the resource is leased.

Abstract: This invention enables authenticated communications (transactions) to take place on a standard I2C bus without requiring modification of existing I2C devices. Read and write transactions occurring on the bus are authenticated using an Authentication Agent and a shared secret key. In addition to allowing verification of the legitimacy of the transactions, the authentication of the I2C transactions enhances the reliability and serviceability of the bus and devices on the bus by allowing the Baseboard Management Controller (BMC) to quickly determine and pinpoint errors.

Abstract: In a multi-node SMP system, at least one processor per node is enabled to execute the SMM task for the hardware resources that are local to that node. Additionally, each node is allocated its own local SMM code copy in its own SMM memory segment, to allow for improved access and a further reduction in internode traffic. In a preferred embodiment, only a signle processor per node is enabled to execute the SMM tasks, and specific SMM memory locations within the SMM memory segments are allocated and used to report status and results from each node. A root node SMM processor monitors the SMM status entries of the other nodes for completion. To further reduce run-time internode traffic, a per-node resource map is created to identify memory and I/O resources that are specific to a particular node. This per-node resource map is then stored locally within the SMM space on each node, respectively.

Abstract: A data processing system suitable for use in a scalable system, including a first set of processors, a first system memory, and scalability logic to connect the data processing system to a second data processing system to form a scaled system. A set of scalability ports are connected to the scalability logic to receive scalability cables connecting the first system to the second system or to another processor board within the same chassis. The system includes system management to cause each of the system's scalability ports to issue an identifiable signal. System management also detects the reception of an identifiable signal, sent by another system, received by any of the scalability ports and reports the reception of the signal to a system management of the second system to determine which ports of the two systems are connected by the cable.
