摘要： Enables any OS of plural OSs within any of plural logical-resource partitions (LPARs) of a CEC to use interpretive execution for synchronously-executable CHSC (channel subsystem call) commands. A CHSC command authorization mask (CCAM) is provided to control which CHSC commands are allowed to execute interpretively (with pass-through), and which commands are executed with hypervisor intervention (as all prior CHSC commands did). By enabling interpretive execution of those commands which can successfully operate with pass-through, significant system efficiency is obtained. And by disabling interpretive execution for a subset of CHSC commands (which are not allowed to execute with pass-through) potential system failures may be prevented. Thus, interpretive execution may be restricted differently among the OSs in a CEC. Novel CHSC command execution now handles multiple images of shared I/O resources by use of image identifiers, which could not be done before. The information requested by any OS issuing a CHSC command is filtered and optionally compacted by the I/O subsystem responding to the command by only providing information obtained from control blocks associated with the OS which issued the command. This is done by having a set of control blocks for each I/O resource, each control block in the set being associated with a particular OS.
摘要翻译：使CEC的多个逻辑资源分区（LPAR）中的任何一个中的多个OS的任何OS能够使用用于同步可执行CHSC（信道子系统调用）命令的解释性执行。提供了一个CHSC命令授权掩码（CCAM）来控制哪些CHSC命令被解释性地执行（具有传递），以及哪些命令由管理程序干预执行（如所有之前的CHSC命令所执行）。通过启用能够通过直通成功运行的命令的解释执行，可以获得显着的系统效率。并且通过禁止CHSC命令的子集（不允许通过执行）的解释执行，可能会阻止潜在的系统故障。因此，CEC中的操作系统之间的解释性执行可能会受到不同的限制。新的CHSC命令执行现在通过使用以前无法完成的图像标识符处理共享I / O资源的多个映像。由发出CHSC命令的任何OS请求的信息被I / O子系统过滤并且可选地通过I / O子系统来响应该命令，仅提供从与发出该命令的OS相关联的控制块获得的信息。这通过为每个I / O资源设置一组控制块来实现，该集合中的每个控制块与特定OS相关联。

摘要： Provides a method for increasing the connectivity of I/O resources to a multiplicity of operating systems (OSs) running in different resource partitions of a computer electronic complex (CEC) to obtain sharing of the I/O resources among the OSs of the CEC, including channels, subchannels (devices), and control units (CUs). The invention provides image identifiers (IIDs) for assigning resources to the different OSs. Each shared I/O resource has a sharing set of control blocks (CBs) in which a respective CB is assigned to (and located by) a respective IID of one of the OSs. Each of the CBs in a sharing set provides a different image of the same I/O resource. The different CB images are independently set to different states by I/O operations for the different OSs, so that the OSs can independently share the same I/O resource.

摘要： A CPU interface recognizing a large very number of I/O interruption queues in a logically partitioned data processing system. Different partitions may contain different guest operating systems. The CPU interface controls how plural CPUs respond to I/O interruptions put on numerous hardware-controlled queues. A host hypervisor program dispatches the guest operating systems. The guests use the I/O interruptions in controlling the dispatching of their programs on the CPUs in a system. The invention allows the number of guest partitions in the system to exceed the number of I/O interruption subclasses (ISCs) architected in the system, and enables the dispatching controls of each guest operating system to be sensitive to different priorities for plural programs operating under a respective guest. The invention provides CPU controls that support alerting the host to enabled I/O interruptions, and provides CPU controlled pass-through for enabling direct guest handling of the guests I/O interruptions.

摘要： The embodiment discloses a method and means for partitioning the resources in a data processing system into a plurality of logical partitions. Host control code may be embodied in programming, microcode, or by special hardware to enable highly efficient operation of a plurality of preferred guest programming systems in the different partitions of the system. The main storage, expanded storage, the channel, and subchannel resources of a system are assigned to the different logical partitions in the system to enable a plurality of preferred guest programming systems to run simultaneously in the different partitions. This invention automatically relocates the absolute addresses of the I/O channel and subchannel resources in the system to their assigned partitions. Also the absolute and virtual addresses of the different guest programming systems are relocated into, as well as page addresses for any expanded storage, their assigned partitions. The guest programming systems generally will be different operating systems. The logical CPU(s) of the guests are dispatched on one or plural real CPUs in the system using the S/370XA SIE (start interpretive execution) instruction. Special operations are provided, including the CPU alerting of other guests in different partitions using I/O interruption signalling. Interception is provided to handle special circumstances.

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 system for reducing purging of a translation lookaside buffer (TLB) to reduce operating system overhead in a system running multiple levels of virtual machines. A system typically must purge TLB entries whenever an underlying page table entry is invalidated due to paging activity on the host machine, or an underlying guest machine. A system for reducing the number of cases in which guest translations are based on host page table entries is provided. Additional logic is supplied to analyze each invalidate page table entry (IPTE) instruction to minimize the extent of purging required as a result of that instruction. When the region relocate facility is in operation, or when no pageable TLB's have been constructed, only the entry corresponding to the page table entry to be invalidated need be purged. This limited purging reduces the overhead by reducing the time spent in purging and the time required in address translation to rebuild the TLB. This time saving results in increased performance in systems with multi-level guests.

摘要： A tightly-coupled processor complex comprises two or more processors, the complex being asymmetric in that a feature available on one processor is not available on at least one other processor. A work selection mechanism selects one of a set of one or more ready work units, each capable of execution on one or more of the asymmetric processors. A processor set identification function identifies an "indirect idle" set of processors which can participate as hosts in work reassignment to make use of a previously idle processor, and identifies an "indirect bump" set of processors which can participate as hosts in work reassignment to displace a lowest priority work unit previously executing - any work reassignment being initiated by an assigner means and comprising an optimized number of work reassignment steps reassigning work among one of the processor sets to accomplish a related assignment goal (making use of a previously idle processor, or displacing a lowest priority work unit).

摘要： A method for controlling both shared and exclusive access for a resource in a multiprocessor system wherein a first-in/first-out queue is formed for tasks suspended while awaiting access and wherein access to the resource provides that control of access required for manipulation of the first-in/first-out queue which is not provided by the atomic nature of compare (double) and swap. Each member of the queue has indicators of the access it requested and of the next most recently enqueued member which has a corresponding indicator. A lockword is established having two parts, a lock flag indicating the status of the resource, whether available, under shared ownership or under exclusive ownership and a lock pointer pointing to the most recently enqueued task. In requesting or releasing access, an initial guess is made as to the value of the lockword and a projected lockword is calculated based on the guess. Then an atomic reference is made to the lockword during which no other multiprocessor has access to the lockword. During the atomic reference, the lockword is compared to the guess of the lockword and if the guess is correct, the lockword is replaced by the projected lockword which rearranges the queue for the requesting or releasing task. If the guess was incorrect, the value of the lockword is used to calculate another projected lockword. If another task can affect the next tasks to gain access, the process with the atomic reference is repeated until no intervening changes occur between atomic references.
