摘要： A method is provided for recovering from an uncorrected memory error located at a memory address as identified by a memory device. A stored hash value for a memory page corresponding to the identified memory address is used to determine the correct data. Because the memory device specifies the location of the corrupted data, and the size of the window where the corruption occurred, the stored hash can be used to verify memory page reconstruction. With the known good part of the data in hand, the hashes of the pages using possible values in place of the corrupted data are calculated. It is expected that there will be a match between the previously stored hash and one of the computed hashes. As long as there is one and only one match, then that value, used in the place of the corrupted data, is the correct value. The corrupt data, once replaced, allows operation of the memory device to continue without needing to interrupt or otherwise affect a system's operation.
摘要翻译：提供一种用于从由存储器件识别的存储器地址处的未校正的存储器错误中恢复的方法。用于与所识别的存储器地址相对应的存储器页的存储的散列值用于确定正确的数据。由于内存设备指定损坏的数据的位置以及发生损坏的窗口的大小，因此可以使用存储的散列来验证内存页重建。利用手头已知的很好的部分数据，可以计算使用可能值代替已损坏数据的页面散列。预期在先前存储的散列和所计算的散列之一将存在匹配。只要有一个只有一个匹配，那么在损坏的数据的位置使用的值是正确的值。损坏的数据一旦被更换，就允许存储设备的操作继续进行，而不需要中断或以其他方式影响系统的操作。

摘要： A software component is executed to carry out a task, the task including a subtask. An external function is called to perform the subtask, the external function executing in a separate thread or process. The component receives an observation recorded by the external function, the observation including an identifier of a possible error condition and instance data associated with the possible error condition. The possible error condition being a cause of the failure of the external function to carry out the subtask. If the task cannot be completed, then a new observation is recorded along with the received observation, the new observation being related to a possible error condition of the component, which is a cause of the failure of the component to carry out the task. When the task can be completed despite the failure of the external function, the observation recorded by the external function is cleared.
摘要翻译：执行软件组件来执行任务，任务包括子任务。调用外部函数来执行子任务，外部函数在单独的线程或进程中执行。该组件接收由外部功能记录的观测值，该观测值包括与可能的错误状况相关联的可能的错误状况和实例数据的标识符。可能的错误条件是外部函数执行子任务失败的原因。如果无法完成任务，则随着接收到的观察结果记录新的观察结果，新的观察与组件的可能的错误状况相关，这是组件执行任务失败的原因。尽管外部功能故障可以完成任务，但通过外部功能记录的观察结果将被清除。

摘要： In one approach, a method is described of generating an interface for an operating system kernel. The method calls for creating an input file, where the input file includes a node structure for the interface. A kernel component of the interface is generated from the input file. A user space component of the interface is also generated from the input file.
