Comments
This APAR will provide support for the IBM z14 and must be applied as part of upgrading z/VM to support the z14 (see "installing z/VM on the IBM z14" section below). The following facilities are supported for guest exploitation in z/VM 6.3.0 and z/VM 6.4.0 on the z14 GA1 processor: - ESA/390-Compatibility-Mode Facility - Miscellaneous-Instruction-Extensions Facility 2 - Vector Enhancements Facility 1 - Vector Packed Decimal Facility - Message-Security-Assist Extension 6 - Message-Security-Assist Extension 7 - Message-Security_Assist Extension 8 This APAR also includes support for the following items in z/VM 6.3.0 and z/VM 6.4.0: - Both shared and dedicated guest use of the new CEX6S crypto card. - Crypto Clear Key ECC operations: Clear-key Elliptic Curve Cryptographic (ECC) operations are supported for guests enrolled in the z/VM-managed shared-crypto queue (APVIRT). The shared-crypto queue must be configured with CCA coprocessor domains in order for the function to be virtualized for guest use. - CPU Measurement Facility (CPUMF) counter enhancements. - Dynamic I/O support: Dynamic I/O support is provided for managing the configuration of OSA-Express6S OSD CHPIDs, FICON Express16S+ FC and FCP CHPIDs, and Regional Crypto Enablement (RCE), zHyperLink, and RoCE Express2 adapters. The available PTF for APAR VM65865 provides dynamic I/O support for the Coupling Express LR adapter in z/VM V6.3.0 and z/VM V6.4.0, and is applicable to both z13 and z14. - RoCE Express2 support: Guest exploitation support for RoCE Express 2 allows the adapters to be brought online and attached to supporting guests for exploitation. - Improved memory management efficiency: the IBM z14 processor design allows greater concurrency in address translation. This improvement may increase z/VM workloads' performance compared to z13, particularly when z/VM is configured to exploit multithreading. - Alternate subchannel set dynamic I/O support: z/VM 6.4.0 provides dynamic I/O commands within the z/VM hypervisor for supporting define, modify, and delete of a device within either the default or alternate subchannel sets. HCD support is currently not available. The following items are supported on z/VM 6.4.0 only: - Instruction simulation counters by virtual CPU in z/VM monitor data. - Firmware assist for invalid-but-resident page revalidation to improve workload performance. NOTE: it is always recommended to apply the compatibility APARs to z/VM before upgrading your hardware. The z14 compatibility PTF for z/VM 6.3.0 and z/VM 6.4.0 must be installed before moving your z/VM system to the z14. Installing z/VM on the IBM z14: z/VM V6.3.0 cannot be installed directly on an IBM z14 server. Instead, z/VM V6.3.0 must be installed on a prior IBM Z server and the PTFs for APARs VM65942 and its prereqs, VM65921, and VM65922 must be applied prior to moving the image to z14. After applying all required service and before IPLing z/VM V6.3.0 on an IBM z14 server, an updated Standalone Program Loader (SAPL) must be installed by using the updated SALIPL MODULE provided by the PTF for APAR VM65856. Otherwise, z/VM V6.3.0 will not successfully IPL on a z14 server. ++ For instructions on installing SAPL, refer to ++ Chapter 2 of the z/VM System Operation 6.3 manual. In Addition, after applying the PTFs for APARs VM65921 and VM65922, the stand-alone dump program must be re-installed using the updated SDINST utility. z/VM V6.4.0 can be installed directly on a z14 server with a V640 install image obtained from IBM after August 25, 2017. The PTF for APAR VM65942 must be applied immediately after installing z/VM V6.4.0. SSI Considerations: The available PTF for prereq APAR VM65976 provides infrastructure support for ESA/390 compatibility mode within z/VM V6.2.0, V6.3.0, and V6.4.0, and must be installed on all members of an SSI cluster before any z/VM V6.3.0 or V6.4.0 member of the cluster is run on an IBM z14 server. For additional details see the PSP bucket: 3906DEVICE 3906/ZVM subset. To support this APAR, new editions of the following publications are available: - SC24-6175, z/VM: CP Commands and Utilities Reference - GC24-6177, z/VM: CP Messages and Codes - GC24-6193, z/VM: General Information - SC24-6198, z/VM: I/O Configuration - GC24-6201, z/VM: Migration Guide - SC24-6208, z/VM: Performance - SC24-6228, z/VM: Running Guest Operating Systems See http://www.vm.ibm.com/library/ for the online version of the updated publications. ×**** PE17/09/07 FIX IN ERROR.
