摘要： A program product, a translation lookaside buffer and a related method for operating the TLB is provided. The method comprises the steps of: a) when adding an entry for a virtual address to said TLB testing whether the attribute data of said virtual address is already stored in said CAM and if the attribute data is not stored already in said CAM, generating tag data for said virtual address such that said tag data is different from the tag data generated for the other virtual addresses currently stored in said RAM and associated to the new entry in said CAM for the attribute data, adding the generated tag data to said RAM and to the associated entry in said CAM, and setting a validity flag in said CAM for said associated entry; else if the attribute data is stored already in said CAM, adding the stored attribute data to the entry in said RAM for said virtual address; and when performing a TLB lookup operation: reading the validity flag and the tag data from the entry in said CAM, which is associated to the entry in said RAM for said virtual address, and simultaneously reading the absolute address and the tag data from the entry in said RAM for said virtual address, and generating a TLB hit only if the tag data read from said CAM is valid and matches the tag data read from said RAM.

摘要： A process is disclosed to serialize instructions that are to be processed serially in a multiprocessor system, with the use of a token, where the token can be assigned on request to one of the processors, which thereupon has the right to execute the command. If the command consists of dristibuted tasks, the token remains blocked until the last dependent task belonging to the command has also been executed. It is only then that the token can be assigned to another instruction. Moreover, a device is described to manage this token, which features three states: a first state, in which the token is available, a second state, in which the token is assigned to one of the processors, and a third state, in which the token is blocked, because dependent tasks still have to be carried out. Moreover, a circuit is disclosed with which the token principle that is introduced can be implemented in a simple manner. The token is only available if none of the processors i is in possession of the token and if no dependent task is pending at any of the processors. The OR chaining of signals to form a signal C which is set if the token is not available represents the basic circuitry with which the serialisation of commands consisting of distributed tasks is carried out. The invention is applied particularly in the case of commands such as IPTE (invalidate page-table entry) and SSKE (set storage key extended), which modify the address translation tables in the memory that are used in common by all processors.

摘要： A lookup operation is performed in a translation look aside buffer based on a first translation request as current translation request, wherein a respective absolute address is returned to a corresponding requestor for the first translation request as translation result in case of a hit. A translation engine is activated to perform at least one translation table fetch in case the current translation request does not hit an entry in the translation look aside buffer, wherein the translation engine is idle waiting for the at least one translation table fetch to return data, reporting the idle state of the translation engine as lookup under miss condition and accepting a currently pending translation request as second translation request, wherein a lookup under miss sequence is performed in the translation look aside buffer based on said second translation request.

摘要： A technique is provided for monitoring a value without repeated storage access. A processing circuit processes an instruction of a program that specifies a memory address of a memory location to be monitored. The processing circuit configures a monitor station for monitoring the memory location. The memory location includes a state descriptor for the program. The processing circuit receives a cross-invalidate request from a memory controller. The cross-invalidate request indicates to the monitor station that content of the memory location has been changed by another processing circuit.

摘要： A system, method and computer program product for providing quiesce filtering for shared memory. The method includes receiving a shared-memory quiesce request at a processor. The request includes a donor zone. The processor includes translation look aside buffer one (TLB1). It is determined that the shared-memory request can be filtered by the processor if there not any shared memory entries in the TLB1 and the donor zone is not equal to a current zone of the processor and the processor is not running in host mode. The shared-memory quiesce request is filtered in response to the determining.

摘要： Buffered indexing for a computer's array such as a cache is used to synchronize parent entries with children and allow background invalidation (that is, suspending the invalidation should a new request of the array come in, resuming the invalidation after the request is satisfied) of the child entries. A method for synchronization uses linking of (multiple) entries in lower-level tables to single entries in a higher-level table with a buffered index value. This index value increments each time the higher-level entry is replaced or invalidated (and thus disassociated with its corresponding lower-level entries). Multiple sets of index values are maintained, so that when one set is exhausted, processing can continue with one of the other sets. All corresponding lower-level entries with index values from the old (dirty) set can then be scrubbed (invalidated) while new entries are built from the new (clean) set. Scrubbing can take place in the background, and can be suspended and resumed at any time so as to not impact request service times of the tables.

摘要翻译： 用于计算机阵列的缓冲索引（例如缓存）用于将父条目与子对象同步，并允许后台无效（即，如果数组的新请求进入，则在暂停请求满足后恢复无效）来暂停无效 子项。 同步的方法使用下级表中的（多个）条目与具有缓冲索引值的更高级别表中的单个条目的链接。 每次上级条目被替换或无效时，该索引值递增（从而与其对应的较低级别条目解除关联）。 维持多组索引值，因此当一个集合耗尽时，处理可以继续其他集合之一。 然后可以从新的（干净的）集合构建新的条目，然后可以擦除（无效）来自旧（脏）集合的索引值的所有相应的较低级别条目。 擦洗可以在后台进行，可以随时暂停和恢复，以免影响表的请求服务时间。

摘要： Storing translation lookaside buffer (TLB) entries are in a TLB1 at the processor. The TLB1 includes entries associated with main storage accesses of programs executing in a guest mode in a current zone and entries associated with main storage accesses of firmware executing in a host mode. A quiesce interruption request is received at the processor that includes a requesting zone indicator. The processor is either executing in the host mode and has no zone or in the guest mode with the current zone. The requesting zone indicator and the contents of a programmable filtering register that indicates exceptions to filtering performed by the processor is used to determine if filtering should be performed. The quiesce interruption request may be filtered based on the requesting zone indicator even after the mode switches from the guest mode to the host mode.

摘要： Processing within a computing environment is facilitated by filtering requests of the computing environment. A processing unit that receives a request determines whether it is to perform the request. This determination is made by, for instance, comparing an identifier of the request with an identifier of the processing unit making the determination. If there is a mismatch, then the request is blocked. Other processing within the computing environment is also facilitated by selectively using buffer entries. The selection criteria is based, for instance, on identifier information.
