摘要： A request is made by a system in a first logical partition, within a logically partitioned data processing system, to dynamically change the I/O configuration of the host system in a way that affects a system in a second logical partition. The hypervisor intercepts the request, ensures the serialization of such dynamic I/O requests, and allows dynamic reconfiguration to proceed. Subsequently, the hypervisor determines the effect of the reconfiguration on the second partition, and notifies the second partition of the change.

摘要： A method and apparatus for specifying offsets from an external time reference (ETR) for selected logical partitions of a partitioned information handling system. Each logical partition has a logical time-of-day (TOD) clock which may be set independently of the host system clock by specifying an epoch offset from the host clock. A system operator is presented with a display panel in which the operator may specify the magnitude and sign of an ETR offset for each logical partition selected to have an ETR offset. Each logical partition, upon being activated, issues a Store Clock (STCK) instruction to read its own logical TOD clock as well as a Store ETR (STETR) instruction to read the ETR. If the logical partition has a specified ETR offset, the logical partition manager simulates the STETR instruction by adding or subtracting the ETR offset to the real ETR time and returning the modified value to the partition; otherwise, the logical partition manager returns the real ETR time to the partition. If the read ETR time (as returned by the STETR instruction) differs from the read logical clock time, the logical partition issues a Set Clock (SCK) instruction to reset the logical partition clock to the ETR time. The logical partition manager simulates this latter instruction by computing the difference between the two times and storing the difference in an epoch offset field for the partition. The invention permits sets of logical partitions to be synchronized to different clock values, either for test purposes or operation in different time zones.
摘要翻译：一种用于指定对于分区信息处理系统的选定逻辑分区的来自外部时间基准（ETR）的偏移的方法和装置。每个逻辑分区具有逻辑时钟（TOD）时钟，其可以通过从主机时钟指定历元偏移来独立于主机系统时钟设置。系统操作员被呈现有显示面板，其中操作者可以为选择为具有ETR偏移量的每个逻辑分区指定ETR偏移量的大小和符号。每个逻辑分区在被激活时发出存储时钟（STCK）指令，以读取其自己的逻辑TOD时钟以及存储ETR（STETR）指令来读取ETR。如果逻辑分区具有指定的ETR偏移量，则逻辑分区管理器通过将ETR偏移量相加或减去实际ETR时间来模拟STETR指令，并将修改的值返回到分区; 否则，逻辑分区管理器将真正的ETR时间返回到分区。如果读取的ETR时间（由STETR指令返回）与读取的逻辑时钟时间不同，则逻辑分区发出设置时钟（SCK）指令，将逻辑分区时钟重置为ETR时间。逻辑分区管理器通过计算两次之间的差异并将该差异存储在分区的时期偏移字段中来模拟后一指令。本发明允许将逻辑分区集合同步到不同的时钟值，用于测试目的或在不同时区中的操作。

摘要： A method of replacing a current version of a program module with a replacement version of the module concurrently with the execution of the program on a computer system. While execution of the program is suspended, each address reference in the program to an entry point within the current version of the module is replaced with an address reference to the corresponding entry point within the replacement version of the module. After the address references have been replaced and before execution is resumed, a patch initialization routine is invoked to perform initialization functions such as storage allocation, table initialization and feature detection that are performed before execution of the concurrently applied patch. Execution of the program is resumed when each address reference to the current module has been replaced with one to the replacement module and the patch initialization routine has been performed. A bit vector is used to ensure that each initialization function is performed only once per instantiation of the program being patched. An available storage value indicates the amount of initially allocated storage remaining available after performing an initialization function involving storage allocation.

摘要： A method and apparatus for synchronizing selected logical partitions of a partitioned information handling system to a test datesource. A system operator is presented with a display panel in which the operator may specify a set of test partitions and a test clock value. Each partition designated as a test partition is synchronized to the test clock value upon being newly activated, while production partitions are synchronized to a production clock value. The first test partition to be newly activated is synchronized to the test clock value by calculating the difference between the test clock value and a host clock value and storing the difference as an epoch offset for that partition. Each subsequently activated test partition is synchronized to the test clock value by copying the epoch offset of the previously activated test partition.
