摘要： The present invention provides a computer system which allows a user to identify which one of a plurality of feature cards has issued an error signal. The device issuing the error signal is then isolated and error recovery techniques, (or re-initialization) are implemented only on the device with the error condition. The computer system includes additional control logic, along with a bridge chip that interconnects different information buses and at least one connector slot for receiving a feature card, which implements specific functions such as I/O, memory, or the like. When it is determined that an error signal is present the system hardware activates and holds a reset signal to the device which issued the error signal. Additionally, a status bit in a register in the bridge chip is set. The device driver corresponding to the device that issued the error signal then reads the status bit and verifies that an error has occurred and then resets the bridge and resets, or initializes only the device having the error condition.

摘要： A computer system is provided which supports an increase in the number of pluggable cards on the secondary I/O bus by using driver/receiver modules and direction control logic in place of more complex and more expensive bus to bus bridges. The number of pluggable cards on the I/O bus in a computer system is limited by the electrical loading of each card and the frequency of operations on the bus. Reducing the bus frequency provides more signal propagation time. The added signal propagation time supports the extension of the bus by driver/receiver modules and logic which controls the direction the driver/receiver modules drive the bus signals. Further, the driver/receiver modules support changing the hardware configuration of the system by adding or removing an I/O card without the need to cease data processing activity for the entire computer.
摘要翻译：提供了一种计算机系统，其通过使用驱动器/接收器模块和方向控制逻辑来代替更复杂和更昂贵的总线到总线桥，支持次级I / O总线上的可插拔卡的数量的增加。计算机系统中I / O总线上的可插拔卡的数量受到每个卡的电气负载和总线上的操作频率的限制。减少总线频率提供更多的信号传播时间。增加的信号传播时间支持由驱动器/接收器模块和控制驱动器/接收器模块驱动总线信号的方向的逻辑扩展总线。此外，驱动程序/接收器模块支持通过添加或删除I / O卡来更改系统的硬件配置，而无需停止整个计算机的数据处理活动。

摘要： A computer system is provided which allows a user to remove or install feature cards without removing the cover to entire computer. A computer cover is provided with rectangular openings which correspond in alignment and size to an electrical connector on the system board. The feature card can then be mechanically attached to the computer cover, or a frame member, with a pivot and guide member. A handle is provided which will allow the user to apply pressure to the card, via the guide member in order to insert or remove the feature card from the connector on the system board. The guide member is constructed such that a vertical force is applied between the card and connector to ensure proper alignment when inserting and removing the adapter card.

摘要： A computer-implemented method, apparatus, and computer program product are disclosed for migrating data from a source physical page to a destination physical page. A migration process is begun to migrate data from the source physical page to the destination physical page which causes a host bridge to enter a first state. The host bridge then suspends processing of direct memory access operations when the host bridge is in the first state. The data is migrated from the source physical page to the destination physical page while the host bridge is in the first state.

摘要： A mechanism for temporarily stalling selected Direct Memory Access (DMA) operations in a physical input/output (I/O) adapter in order to permit migration of data between physical pages that are subject to access by the physical I/O adapter. When a request for a DMA to a physical page in system memory is received from an I/O adapter, a migration in progress (MIP) bit in a translation control entry (TCE) pointing to the physical page is examined, wherein the MIP bit indicates whether migration of the physical page referenced in the TCE to another location in system memory is currently in progress. If the MIP bit indicates a migration of the physical page is in progress, the DMA from the I/O adapter is temporarily stalled while other DMA operations from other I/O adapters to other physical pages in system memory are allowed to continue.

摘要： A method, apparatus, and computer program product are disclosed in a shared processor data processing system for coordinating error reporting for and resetting of a physical I/O adapter that supports virtualization. The physical I/O adapter is virtualized by generating virtual I/O adapters that each represent a portion of the physical I/O adapter. Each one of the virtual I/O adapters is assigned to a different one of client logical partitions. A determination is made regarding whether the physical I/O adapter may have experienced an error. If the physical I/O adapter has experienced an error, all of the client logical partitions are notified about the error and a recovery of the physical I/O adapter is coordinated among all of the client logical partitions by waiting for each client logical partition to acknowledge the error notification before the physical I/O adapter is reset.
