Problem conclusion

Temporary fix

Comments

  • This enhancement makes z/VM's APVIRT crypto message
    processing more event-driven by using crypto-related
    interruptions to drive crypto work.
    
    The following externals have been added for this support:
    1. The CRYPTO APVIRTUAL system configuration statement is
       updated to allow a new POLLING option.  This option
       can be used to specify whether CP uses polling or
       interruptions to drive the processing of crypto work
       that is assigned to the shared pool.  This statement
       is documented in chapter 6 of CP Planning and
       Administration (SC24-6271-10).
    2. A new SET CRYPTO command is introduced and can be used
       to specify whether CP uses polling or interruptions
       to drive the processing of crypto work that is
       assigned to the shared pool.  This command is
       documented in chapter 2 of the CP Commands and
       Utilities Reference (SC24-6268-11).
    3. The QUERY CRYPTO command is enhanced to accept
       APVIRTUAL POLLING as operands.
       QUERY CRYPTO APVIRTUAL POLLING can be used to request
       a display of the polling setting for the shared pool.
       This command is documented in chapter 2 of the
       CP Commands and Utilities Reference (SC24-6268-11).
    4. One new message is added.  This message is documented
       in chapter 3 of CP Messages and Codes (GC24-6270-10).
       171301  E A required facility is not available to
                 allow Crypto to operate with polling off.
                 Polling remains on.
