Problem conclusion

Temporary fix

Comments

  • This APAR will provide support required for the IBM z13
    (z13) D/T2964 and must be applied as part of installing z/VM
    on a z13.  The following items are supported in z/VM 6.2
    and z/VM 6.3:
    
    
    1.  New hardware facilities for guest use:
          Load/Store-On-Condition Facility 2
          Load-and-Zero-Rightmost-Byte Facility
          Decimal-Floating-Point Packed Conversion Facility
          Delay Facility
          Message-Security-Assist Extension 5
    
    2.  Integer or Binary Floating Point for Capability Numbers
          Capability numbers have an inverse relationship to the
          speed of the machine, thus as machines get faster,
          there is need for fractional capability numbers.
          Accounting and monitor records will now report integer
          and binary floating point numbers for capability values
          while Q CAPABILITY will now report decimal numbers for
          capability values.
    
    3.  No guest zAAP support on z13:
          On the z13 the zAAP CPU type will not be supported
          either in real hardware or in the LPAR configuration.
          Similarly, z/VM will not allow guests to define this
          type, if the machine does not support it.
    
    4.  Guest support for the Crypto Express5S feature:
          This feature is exclusive to the z13.  The Crypto
          Express5S can be configured in one of three ways using
          the Hardware Management Console (HMC) panels:
                IBM Common Cryptographic Architecture (CCA)
                 coprocessor
                IBM Enterprise Public key Cryptography Standards
                 (PKCS) #11 (EP11) coprocessor
                Accelerator
    
        Guests can be authorized in the z/VM directory for
          shared or dedicated access to the Crypto Express5S.
          When Crypto Express5S is configured as an accelerator
          or a CCA coprocessor, z/VM supports the device for
          shared or dedicated use.  When Crypto Express5S is
          configured as an EP11 coprocessor, z/VM supports the
          device for dedicated use only.
    
    5.  Support for more AP Crypto features and more domains:
          z/VM supports an increase in the maximum number of
          domains per crypto feature from 16 to 256.  It also
          supports an increase in the maximum number of crypto
          features, referred to as Adjunct Processors (APs),
          from 64 to 256.
    
        The z13 processor will provide support for up to 16 APs
          with 85 domains on each, using the new Crypto Express5S
          and the Crypto Express4S features.
    
        DIRECTXA will accept the larger AP and domain numbers on
          the CRYPTO statement in the z/VM user directory.
    
        The increase in the domain and AP numbers from two digits
          to three digits causes changes in the responses for the
          Q CRYPTO and Q VIRTUAL CRYPTO commands and in crypto
          error and informational messages.
    
    6.  Greater control over choice of crypto resources for shared
        use:
          A new CRYPTO APVIRTUAL statement may be included in the
          system configuration file.  This statement allows the
          administrator to specify which domains on which APs
          (crypto resources) should be used for sharing.  If this
          statement is omitted, a limit of two crypto resources
          will be chosen for shared use by default.  Any crypto
          resources not designated for shared use at IPL time will
          be available for dedicated use.
    
    7.  Support for a VCHID operand on the DEFINE CHPID command
          for IQD type channel paths.
    
    8.  Dynamic I/O support for the new type CS5 (Coupling over
          PCIe/ICB-P) channel paths, allowing these channels
          to be defined or modified.
    
    In addition, the following items are supported in z/VM 6.3
    only:
    
    1.  Guest exploitation of PCI address translation
          enhancements provided on z13.
    
    2.  Enhancements to the PCI Function Measurement data:
          New measurement fields for the various PCI function
          types will be correctly indicated in guest measurement
          blocks and Performance Toolkit reports.
    
    A memo to users is provided with instructions for the
    new versions of the DIRECTXA and SALIPL utilities and
    additional notes about the new cryptographic support.
    
    Please see VM65588 for corresponding IBM Directory
    Maintenance (DirMaint) updates and VM65527 for
    corresponding IBM Performance Toolkit (PerfKit) updates.
    
    Note:  It is always recommended to apply the compatibility
    APAR to z/VM before upgrading your hardware.  z/VM 6.3.0
    can be installed directly on the z13 and service for
    VM65577 applied immediately afterward.  For z/VM 6.2.0,
    however, at a minimum, APAR VM65007 must be applied before
    the z/VM system 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.
    
    To support this APAR, new editions of the following
    publications are available:

    of the updated publications.
    .
    VM65577 also includes a fix for a problem in z/VM dedicated
    crypto support (CRYPTO APDEDICATED specified in the user
    directory) which may occur when running a single system image
    (SSI) cluster.
    .
    Problem Description: VM Guest is unable to access Crypto
    Hardware from a member of an SSI.
    .
    Full Error Description: This problem can result in one z/VM
    system in the relocation domain running Linux guests using the
    crypto hardware while Linux guests on the other system cannot
    access the crypto hardware.  If there is a facility installed
    and supported on one system which is not on the other system,
    the architecture level for the relocation domain will be set to
    the common level which does not include that facility. This
    causes interception of the crypto instruction which checks the
    crypto hardware on the system with the additional architecture
    facility. This interception is not handled correctly by z/VM,
    and guests, such as Linux on System z using the zcrypt device
    driver, are not able to detect the crypto hardware. This problem
    is resolved by applying VM65577.
