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： 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 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.
摘要翻译：用于减少翻译后备缓冲器（TLB）的清除以减少运行多级虚拟机的系统中的操作系统开销的系统。由于主机或基础客机上的分页活动，每当基础页表项无效时，系统通常必须清除TLB条目。提供了一种用于减少客户转换基于主机页表项的情况的系统。提供附加逻辑来分析每个无效页表项（IPTE）指令，以最小化该指令所需的清除范围。当区域重新定位设施正在运行时，或者当没有构建可页面的TLB时，只需要清除与该页表项对应的条目即可。这种有限的清除通过减少清除时间和地址转换所需的时间来重建TLB来减少开销。节省时间可以提高具有多级客人的系统的性能。

摘要： A system and method for dispatching logical central processing units (CPUs) among physical CPUs in a multiprocessor computer system having multiple logical partitions, wherein the cryptographic facilities may not be interchangeable. According to the present invention, the logical CPUs are dispatched among the physical CPUs according to either an affinity, floating, or disabled scheduling method. The affinity scheduling method is used when the crypto facilities are not interchangeable or when non-interchangeable crypto functions are performed. The floating scheduling method is used when the cryptographic facilities are interchangeable and interchangeable crypto functions are performed. The disabled scheduling method is used when the logical CPU is not authorized to issue cryptographic instructions.

摘要： A data processing system operated with multiple levels of virtual machine guests under a host control program. The second level of guests are invoked, operated, and terminated without host intervention, as has been required in prior systems, to significantly increase the operating efficiency of the system. Address translation is done by providing machine capability to translate second level guest addresses to real memory addresses taking advantage of the first level guest being located at a simple offset within real memory. Special facilities for second level guests periodically test for timing interruptions for second level guests and update the second level guest timing facilities.

摘要： The embodiments enable address translations for a virtual machine in the TLB (translation lookaside buffer) of a CPU to be retained from exiting a SIE (start interpretive execution) instruction to the next SIE entry to interpretive execution for the same guest (virtual machine CPU). Conditions are defined which determine when guest TLB entries must be invalidated. These conditions require invalidation of guest TLB entries only within and on entry to interpretive execution. A single invalidation of guest TLB entries on entry to interpretive execution is required for any number of conditions recognized while a CPU is not in interpretive execution state. For a guest in a virtual multi-processor (MP) machine, an interlock is provided to allow the use of guest virtual addresses by host instruction simulation and the need for guest TLB invalidation is broadcast to all other real CPUs in a real MP system so that all guest TLBs on all real CPUs can be invalidated to maintain integrity. No broadcast or interlock is needed for a guest in a virtual uni-processor (UP) machine.
摘要翻译：这些实施例使得要保留的待保留的CPU的TLB（转换后备缓冲器）中的虚拟机的地址转换不会从SIE（开始解释执行）指令移除到下一个SIE条目以解释相同来宾（虚拟机CPU）的执行。定义条件是确定何时必须使客户端TLB条目无效。这些条件仅在客户TLB条目中无效，仅在解释执行过程中和之后才进行。在CPU不处于解释执行状态时，对于识别的任何数量的条件，需要对进入解释执行的客户TLB条目单一无效。对于虚拟多处理器（MP）机器中的客人，提供互锁以允许通过主机指令模拟使用来宾虚拟地址，并且将客户TLB无效的需求广播到真实MP系统中的所有其他真实CPU，因此所有实际CPU上的所有客户端TLB都可以无效以保持完整性。虚拟单处理器（UP）机器中的客人不需要广播或互锁。

摘要： Enables a host (hypervisor) to access any location in any guest zone in a large memory, when host and guest operands have small addresses that cannot access locations outside of their own zones. System hardware/microcode provides a particular number of windows for host use. Each CPU in the system has one or more window access registers (WARs), and one or more window registers (WRs). The host uses a load WAR instruction to designate each page frame (PF) in the host zone to be used as a host window, and each PF is associated with a respective window number. When the host receives an interception signal requiring the host to access a guest location represented by a guest zone identifier and a guest small address, the host designates one of its window numbers for an access to this guest location. Then, the host executes an activate WR instruction which invokes CPU hardware/microcode that generates a large absolute address for accessing this guest location in the large memory and stores it in a WR associated with the window number. When the host thereafter executes any instruction with an operand small address accessing the host window PF associated with that WR, and CPU hardware/microcode automatically substitutes that guest large address in the WR for the host operand small address for accessing the guest location.
