摘要： An information processing system is provided which includes a plurality of system resources, and an event queue having a predetermined number of entries. An event recording mechanism of the information processing system is operable to make entries regarding events in the event queue, wherein the entries are limited to a predetermined number of active entries in the event queue per each type of event per each of the system resources. In a particular embodiment, the number of entries per each type of event for each of the system resources is limited to one.

摘要： Methods and apparatus for reducing the impact of latency associated with decrypting encrypted data are provided. Rather than wait until an entire packet of encrypted data is validated (e.g., by checking for data transfer errors), the encrypted data may be pipelined to a decryption engine as it is received, thus allowing decryption to begin prior to validation. In some cases, the decryption engine may be notified of data transfer errors detected during the validation process, in order to prevent reporting false security violations.

摘要： A circuit arrangement and method selectively reorder speculatively issued memory read requests being communicated to a lower memory level in a multi-level memory architecture. In particular, a memory read request that has been speculatively issued to a lower memory level prior to completion of a cache lookup operation initiated in a cache memory in a higher memory level may be reordered ahead of at least one previously received and pending request awaiting communication to the lower memory level. By doing so, the latency associated with the memory read request is reduced when the request results in a cache miss in the higher level memory, and as a result, system performance is improved.

摘要： A method, system, and computer program product are disclosed within a logically partitioned data processing system for providing an aliased queue pair for each logical partition for the single general services management queue pair that exists within a physical host channel adapter. Packets intended for the logical ports are received at the physical port. Multiple partitions exist within the data processing system. When one of these partitions needs to use one of the logical ports, a queue pair is selected. The queue pair is then associated with the logical port. The queue pair is configured as an aliased general services management queue pair and is used by the partition as if the aliased queue pair were the single general services management queue pair provided in the channel adapter.

摘要： A Host Channel Adapter supporting a plurality of Logical Partitions is provided. A Subnet Manager, having an associated aliased Queue Pair, may run in a Logical Partition. A single physical subnet management Queue Pair and its associated firmware are provided for each physical port in the Host Channel Adapter. If a packet is to be routed to a Subnet Manager residing in a Logical Partition, the packet is enqueued on the physical port's send queue for transmission to the aliased Queue Pair for the Subnet Manager. The Host Channel Adapter hardware loops the packet back to the aliased Queue Pair in the appropriate Logical Partition. The aliased Queue Pair is also capable of transmitting packets that are looped back to a Hypervisor Subnet Management Agent.
