摘要： A resource and partition manager of the preferred embodiments includes a lock mechanism that operates on a plurality of locks that control access to individual I/O slots. The resource and partition manager uses the lock mechanism to obtain a lock on an I/O slot when transferring control of the I/O slot to a logical partition that is powering on and when removing the I/O slot from a logical partition that is powering off. The resource and partition manager uses the lock mechanism to remove control of an I/O slot from, or return control to, an operating logical partition in order to facilitate hardware service operations on that I/O slot or on the physical enclosure in which it is contained.

摘要： A resource and partition manager includes a power on/power off mechanism that is used to assure a hardware resource is powered down when control of the resource is removed from a logical partition, and to assure the hardware resource is powered up when control of the hardware resource is transferred to a logical partition. In the alternative, the resource and partition manager may simply place the hardware resource in a power on reset state when the hardware resource is transferred to a logical partition. In this manner, when made available to a partition, the hardware resource is in a power-on reset state, which is the state typically expected by the logical partition.

摘要： A partition manager includes a resource detection mechanism that uses a persistent resource database to determine which resources were seen previously, and to determine which resources are required for a logical partition to start. Once all required resources for a logical partition are detected, the logical partition is started. In this manner, a logical partition may be started as soon as all of its resources are available, without waiting on the resources of other logical partitions. In addition, a missing required resource will prevent a logical partition from starting, thus avoiding the crash of a logical partition due to missing resources.

摘要： An interrupt and message batching apparatus and method reduces the number and frequency of processor interrupts and resulting context switches by grouping I/O completion events together with a single processor interrupt in a manner that balances I/O operation latency requirements with processor utilization requirements to optimize overall computer system performance. The invention sends a message from a processor complex to an I/O adapter on an I/O bus commanding an I/O device connected to the I/O adapter to perform a function. Upon completion of the commanded function, the message processor in the I/O adapter generates a message and sends it to the processor complex on the I/O bus. The message is enqueued in the message queue of the memory, a message count is updated, and processor complex interrupt is signalled if and when the message count exceeds a message pacing count. A signalling timer may also be programmed with a fast response time value if the message has a relatively high latency or with a slow response time value if the message has a relatively low latency. The signalling timer is started when the message is enqueued and the processor complex interrupt is then signalled when the message count exceeds the message pacing count or when the signalling timer has elapsed.

摘要： Method, apparatus and system for isolating input/output adapter error domains in a data processing system. Errors occurring in one input/output adapter are isolated from other input/output adapters of the data processing system by functionality in a host bridge that connects the input/output adapters to a system bus of the data processing system, thus permitting the use of low cost, industry standard switches and bridges external to the host bridge.

摘要： A method, which may be embodied upon a computer readable medium and executed by a processor, for PCI IO using PCI device memory mapping in a logically partitioned system. The method may include the steps of detecting PCI devices in a bus walk initialization process, and associating a pseudonym address range with each PCI device detected in the bus walk initialization process. The method may further include updating PCI device IO resources for each PCI device detected with the associated pseudonym address range, and accessing the detected PCI devices with a device driver using the pseudonym address range stored in the PCI device IO resources.

摘要： An apparatus, system and method permitting a variety of reset procedures and corresponding reset states. A device reset control register is provided for each I/O device adapter in single function or multifunction devices. The device reset control registers permit a greater degree of control over single function devices, multifunction device as a whole and individual device functions within a multifunction device. A device immediate status register synchronizes the various reset procedures. A logical power on reset procedure, a directed unit reset procedure and a directed interface reset procedure utilize the greater degree of control that the device reset control registers provide to force the I/O device adapter, single function device or multifunction device into a corresponding logical power on reset state, a directed unit reset state or a directed interface reset state. Each of these reset states is well-defined and has the advantage of predictable behavior during and after execution of the corresponding reset procedure. A built-in self-test procedure is also defined that sequentially examines each function associated within a multifunction device connected to the local bus to coordinate the initiation, execution and completion of built in self-tests.
