Comments

• This APAR will provide support for the IBM z13 (z13s) D/T2965
  and must be applied as part of installing z/VM on a z13. The
  following items are supported in z/VM 6.2.0 and z/VM 6.3.0:
  
    - Updates to SYSEVENT QVS for LPAR Group Absolute Capacity
      Capping
  
  in addition, the following items are supported in z/VM
  6.3.0 only:
  
    - LPAR Group Absolute Capacity Capping. This PTF is required
      when LPAR Group Absolute Capacity Capping is in use. This
      function allows an absolute capacity cap to be set, by CPU
      type, on a group of LPARs. This allows each of the
      partitions to consume capacity up to their individual limits
      as long as the group's aggregate consumption does not exceed
      its absolute capacity limit. The z/VM support includes
      use of this information in functions that exploit or report
      processor capacity information for the purpose of tolerating
      it's use.
    - DSVBK lock statistics are added to monitor record
      D0 R23 MRSYTLCK.
    - The STSI 1.2.2 CPU speeds are added to monitor records
      DIR4 MRMTRSYS and DIR18 MRMTRCC.
    - Single Increment Assign Control is exploited by dynamic
      memory upgrade to ATTACH a storage element and ASSIGN a
      single storage increment, rather than automatically ASSIGN
      all storage increments in the storage element.
    - The z/VM algorithm which performs I/O to the crypto adapters
      for APVIRT shared crypto guest support is updated to account
      for the faster speeds of modern crypto adapters. This
      benefits all guest programs using APVIRT support, including
      the zcrypt cryptographic device driver for Linux on
      z Systems.
    - Crypto performance monitor record D5 R9 is updated to
      include the interval time between processing
      guest enqueue and dequeue operations.
  
  The following hardware architectures will also be supported
  with this PTF:
  
    - Virtual PCI Devices for SMC-L
  
  Note: it is always recommended to apply the compatibility APARs
        to z/VM before upgrading your hardware. z/VM 6.3.0 can
        be installed directly on the z13 and service for VM65577
        and VM65716 applied immediately afterward. For z/VM 6.2.0
        however, at a minimum, APAR VM65007 must be applied before
        z/VM will IPL successfully on the z13. It is recommended
        that you install the z13 compatibility PTF for
        z/VM 6.2.0 before moving your z/VM 6.2.0 system to the
        z13.
