    This APAR provides z/VM support for the IBM z16 family and
    allows guests to use the following facilities:
      - Neural Network Processing Assist Facility
      - Processor Activity Instrumentation Facility for
        Cryptographic Functions (CPACF) Counters Support
      - Breaking-Event-Address Register Enhancement Facility
      - Reset DAT Protection Facility
      - Vector-Packed-Decimal-Enhancement Facility 2
      - Consolidated Boot Loader to IPL guests from a SCSI LUN
      - 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, supported on IBM LinuxONE
        only.  z/VM provides guest exploitation support. In
        addition, z/VM 7.3 supports defining Fixed-Block
        Architecture (FBA) EDEVICEs on IBM Adapter for NVMe
        devices.
    
    Additionally, support for CPU/core topology location information
    is included in z/VM monitor data.

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:
