摘要： EEH methods are used during the boot process to actively disable a defective PCI adapter, thereby allowing the system boot to continue without disruption. This allows faulty adapters to be present in the machine without interrupting the boot process. The slots appear to be empty and the devices/adapters residing therein can be actively “hot swapped” out without altering the rest of the machine state.
摘要翻译：在引导过程中使用EEH方法主动禁用有缺陷的PCI适配器，从而允许系统启动继续而不中断。这允许错误的适配器存在于机器中，而不会中断启动过程。插槽看起来是空的，其中驻留在其中的设备/适配器可以在不改变机器状态的其余部分的情况下主动“热插拔”。

摘要： A method and apparatus to provide accurate and automated timing of firmware routines, such as initialization tasks at boot time, is provided. Since each task sends a progress indicator code to a display buffer when it starts to run, by saving processor time stamps at the time these codes change, it is possible to calculate and store the time duration for each routine. In the case of system initialization, these time durations can be an indication of problems if they are much longer than normal or an indication of excessive, inefficient, or ineffective processing that might be speed up in order to reduce the total boot time.
摘要翻译：提供了一种提供固件例程的准确和自动定时的方法和装置，例如在启动时的初始化任务。由于每个任务在开始运行时都会将进度指示器代码发送到显示缓冲区，通过在这些代码更改时保存处理器时间戳，可以计算并存储每个例程的持续时间。在系统初始化的情况下，如果这些持续时间比正常时间长得多，或者指示可能加速以减少总启动时间的过程，低效或无效的处理，这些持续时间可以是问题的指示。

摘要： A system, method, and computer program product are disclosed for preventing machine crashes due to hard errors in one of multiple, different processors that are included in a logically partitioned data processing system. An error occurring in one of the processors is detected. A determination is then made regarding whether the processor has been deconfigured. The partition is then rebooted only in response to a determination that the processor has been deconfigured and will not be included in the partition processor resources. Thus, only the configured processors are rebooted. The deconfigured processor is not rebooted.

摘要： A system and method for monitoring a host computer using a service processor is provided. A shared nonvolatile random access memory (NVRAM) area is used to store progress information from the host computer system. The host computer system writes progress information corresponding to the initialization step being performed to the shared NVRAM and also updates a host pointer in the NVRAM. The service processor reads the shared NVRAM and compares its pointer with the host pointer to determine whether new host initialization activity has been reported. The service processor sets a timer so that if host activity is not reported during a set amount of time an error condition occurs causing the service processor to handle the host computer error. An optional service processor routine determines whether the host computer is stuck in an initialization loop whereupon the service processor once again handles the host computer error.
摘要翻译：提供了一种使用服务处理器监视主机的系统和方法。共享的非易失性随机存取存储器（NVRAM）区域用于存储来自主机系统的进度信息。主计算机系统将与正在执行的初始化步骤相对应的进度信息写入共享NVRAM，并且更新NVRAM中的主机指针。服务处理器读取共享NVRAM并将其指针与主机指针进行比较，以确定是否已经报告了新的主机初始化活动。服务处理器设置定时器，使得如果在设定的时间内没有报告主机活动，则出现错误状况导致服务处理器处理主机错误。可选的服务处理器例程确定主计算机是否卡在初始化循环中，服务处理器再次处理主计算机错误。

摘要： A system, method, and computer program product are disclosed for executing a reliable warm reboot of one of multiple partitions included in a logically partitioned data processing system. The data processing system includes partition hardware. A request to reboot a particular partition is received within the partition where the particular partition includes multiple processors. Prior to executing the reboot request, the partition hardware is set to a predetermined state. The reboot request is then executed within the particular partition. The predetermined state is preferably achieved by resetting the partition hardware to a predetermined state.

摘要： A method, system, and computer program product for enforcing logical partitioning of input/output slots within a data processing system is provided. In one embodiment, the system includes a hypervisor and at least one DMA address checking component. The hypervisor receives non-direct-memory-access requests for access to input/output slots and prohibits devices within one logical partition from accessing the input/output slots assigned to a different logical partition. The DMA address checking component receives direct-memory-access requests and prohibits requests for addresses not within the same logical partition as the requesting device from being completed. Requests with addresses corresponding to the same logical partition as the requesting device are placed on the primary PCI bus by the DMA address checking component for delivery to the system memory.

摘要： A computer implemented method, data processing system, and computer usable program code are provided for implementing a two phase open firmware driver. A computer system probes a device for a dummy image that uses open firmware code in a compiled format. The computer system executes the dummy image. The dummy image has a dummy OPEN method and minimal properties for the device. The dummy OPEN method byte-loads a full image that uses open firmware code in a compiled format and transfers control to an OPEN method contained in the full image. The computer system loads the dummy OPEN method and minimal properties into a memory in the computer system.

摘要： A method, apparatus, and computer instructions for recovering terminated partitions in a logical partitioned data processing system. A termination of a partition in a set of partitions associated with a host bridge in the logical partitioned data processing system is detected. The state of other partitions within the set of partitions is checked in response to detecting the termination. A recovery process is initiated if all partitions in the set of partitions have terminated. Input/output slots associated with the host bridge are reset to a normal state if the recovery process is successful. The set of partitions is rebooted after resetting the input/output slots associated with the host bridge without rebooting the logical partitioned data processing system.

摘要： A system for managing input/output drawers within a data processing system. A unique identifier is assigned to each of a plurality of drawers, and is used by the operating system to identify the drawers in the system regardless of how these drawers are interconnected. Another unique PCI-bridge identifier is assigned to each of a plurality of PCI Host bridges (PHBs) from all drawers, and is used by the operating system to perform input/output processes to devices associated with the plurality of PHBs such that the ODM object for each of the PHBs remains the same regardless of how the drawer is interconnected in the system. When a new drawer is added to the system, a new unique identifier is assigned to the new drawer ensuring that the unique identifiers previously assigned to the other drawers are not used to identify the new drawer.
