Problem summary
**************************************************************** * USERS AFFECTED: All installations of z/VM planning to move * * to the IBM z17 family ( D/T9175 ). * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: APPLY PTF * **************************************************************** This APAR provides z/VM compatibility and EQDIO exploitation support for the IBM z17 and IBM LinuxONE Emperor 5 servers. The IBM z17 and IBM LinuxONE Emperor 5 servers make up the IBM z17 family of servers D/T9175. With the applicable PTFs and all required pre-requisite service applied z/VM will provide support for the following IBM z17 family ( D/T9175 ) server hardware facilities: Guest enablement to exploit the following facilities: -Vector-Enhancements Facility 3 - New instructions intended to provide performance improvements. -Vector-Packed-Decimal-Enhancement 3 - Intended to provide performance improvements of COBOL programs when compiled using the NUMCHECK option to detect and convert data. -Workload-Instrumentation - Provides a means of classifying and sampling workloads to enhance the z/OS pricing model. -Message-Security-Assist Extensions - Enhancements that allow the use of XTS and HMAC algorithms and allow for generation of XTS and HMAC encryption keys while using AES algorithms. -Perform Lock Operation (PLO) - Provides operations for managing locks in storage to replace capabilities provided previously by the constrained transactional execution (CTX) facility. -Concurrent-Functions - Provides new instructions intended to replace the use of TX for software serialization. Host support for the following new facilities: -CPU Measurement Facility (CPU-MF) enhancements - Provide CPU-MF-specific support for IBM z17 family server. -Data Processing Unit (DPU) Next Generation I/O accelerator instrumentation provided within the z/VM monitor - Collects FCP, FICON, and OSA instrumentation data within the z/VM monitor for the IBM z17 family server DPUs. Real device support - Allows the following to be attached for guest exploitation: -Enhanced QDIO (OSH) devices. -Network Express Hybrid (NETH) devices. Dynamic I/O and HCD support added for: -Enhanced QDIO (OSH) CHPIDs and subchannels -CL6 coupling adapter CHPIDs -Network Express Hybrid (NETH) PCIe Functions Guest exploitation support for EQDIO devices - Allows guests to directly exploit the OSH functionality of the Network Express Adapter. Extension of CP VSWITCH logic for Network Express Adapter EQDIO support within the z/VM VSwitch - Allows customers to configure the VSwitch to take advantage of lower latency and higher bandwidths provided by networking EQDIO devices within their data center. The VSwitch EQDIO exploitation includes QDIO-to-EQDIO translation, allowing guests that do not support EQDIO to directly take advantage of this networking support. Reduced support for transactional execution (TX) - Non-constrained transactions will result in unconditionally aborting with condition code 1 (CC1) and no TDB stored. Power Consumption metrics provided within z/VM monitor - enhancements to the z/VM monitor to include entire CPC and LPAR specific level power consumption information. This information includes power metrics for CPU, I/O, and Memory usage. Consumers of z/VM monitor, such as the z/VM performance datapump, can be enhanced to calculate/approximate guest level apportionment. APAR VM66826 provides support for a Performance Datapump Power Metric Dashboard. ---- Please note the following: There are source code recompile requirements specific to users of the HCPVINOP MACRO and vendor products that use the macro. Any users of the HCPVINOP MACRO are required to recompile their local updates before using this service. For users of vendor products, please contact the vendor to inquire whether they use the HCPVINOP macro. If so, obtain recompiled source from the vendor.
