Comments
This APAR provides z/VM support for the IBM z16 family and allows guests to use the following facilities: - Neural Network Processing Assist Facility for embedded artificial intelligence acceleration. - Processor Activity Instrumentation Facility for compliance- ready CP assist for Cryptographic Function (CPACF) counters. - Breaking-Event-Address Register Enhancement Facility to facilitate the debug of wild branches. - Reset DAT Protection Facility, which provides a more efficient way to disable DAT protection. - Vector-Packed-Decimal-Enhancement Facility 2, which delivers new instructions that are intended to provide performance improvements. - Consolidated Boot Loader to IPL guests from a SCSI LUN with or without the DUMP option. The GUEST is required to have a minimum virtual memory size of 768MB. - RoCE Express3 Adapter for guest exploitation of Routable RoCE, Zero Touch RoCE, and SMC-R V2 support. - The Crypto Express8S (CEX8S) Adapter shared and dedicated guest support. - IBM Adapter for NVMe 1.1, LinuxONE only. Additionally, support for CPU/core topology location information is included in z/VM monitor data to provide a better picture of the system for diagnostic purposes. Requisite or related APARs: The PTF for APAR VM66504 provides infrastructure support in z/VM 7.1 and 7.2 for the IBM z16 family and must be installed on all the members of an SSI cluster before any member is IPLed on the IBM z16 family. Additionally, the PTF for APAR VM66206 provides infrastructure support for z/VM 7.1 and must be installed on all members of an SSI cluster before any z/VM 7.1 member of the cluster is IPLed on the IBM z16 family. Both PTFs are included in the base of z/VM 7.3. The following publications are updated.
