 NAME       : HCPMCVBK
 DESCRIPTION: VIRTUAL MACHINE CHECK BLOCK
 DSECT      : MCVBK
 FUNCTION   : HCPMCVBK MAINTAINS THE DESCRIPTION OF A MACHINE CHECK
              INCIDENT BEFORE THE INTERRUPT IS REFLECTED TO THE GUEST.
              THERE ARE THREE TYPES OF MCVBKS MAINTAINED IN THE SYSTEM.
              MCVBK (DYNAMICALLY ALLOCATED MCVBK)
              STORAGE  IS OBTAINED  FOR  A DYNAMICALLY  ALLOCATED
              MCVBK WHEN REQUIRED.  IT HAS  TWO USES. THE CONTROL
              PROGRAM BUILDS  MCVBKS WHEN  SOME SYSTEM  INCIDENT,
              THAT  IS  NOT  A  REAL  MACHINE  CHECK,  IS  TO  BE
              REFLECTED TO THE  GUEST AS A MACHINE  CHECK.  IT IS
              ALSO USED  TO MAKE  COPIES OF  MCVBKS TO  ALLOW THE
              REFLECTION OF  MACHINE CHECKS TO  A GUEST  TO OCURR
              ASYNCHRONOUSLY WITH OTHER CP FUNCTION.
              MCVBK (CPU MCVBK)
              WE REFER TO  THIS MCVBK AS THE  'CPU MCVBK' BECAUSE
              EACH CPU OWNS ONE, AND  ALSO TO DISTINGUISH IT FROM
              THE  'SYSTEM  TERMINATION MCVBK'  DESCRIBED  BELOW.
              THE CPU MCVBK  CONTAINS A DESCRIPTION OF A REAL ERROR
              INCIDENT  (IF ANY)  CURRENTLY IN  PROGRESS ON  THIS
              CPU.  IT  IS NEEDED MAINLY  FOR THE BENEFIT  OF THE
              VIRTUAL  SIDE  OF  THE SYSTEM  (HCPGMCMC)  SO  THAT
              MACHINE CHECKS CAN BE  REFLECTED TO GUESTS.  HCPMCH
              CALLS HCPGMCMC AND PASSES  THE CPU MCVBK CONTAINING
              THE DESCRIPTION OF THE INCIDENT.   THE CPU MCVBK IS
              ANCHORED IN THE PREFIX PAGE BY 'PFXMCVBK'.
              DATA IS  PLACED IN  THE MCVBK  AT THE  START OF  AN
              INCIDENT AND IS CLEARED AT  THE END OF THE INCIDENT
              SO  THAT THE  BLOCK REMAINS  EMPTY  UNTIL THE  NEXT
              INCIDENT.
              MCVBK (SYSTEM TERMINATION MCVBK)
              THERE ARE ALSO 'SYSTEM TERMINATION' MCVBKS (THERE
              ARE 32 IN THE SYSTEM).  THEY ARE PERMANENTLY ALLO-
              CATED IN A WORK AREA HCPWRKMV AND REMAIN INTACT
              ACROSS A SYSTEM TERMINATION AND SOFTWARE-RE-IPL.
              THEY ARE USED TO PASS REAL MACHINE CHECK (OR OTHER
              SYSTEM INCIDENT) DESCRIPTIONS TO INDIVIDUAL VMDBKS
              IN THE V=R GUEST CONFIGURATION SO THAT MACHINE
              CHECKS MAY BY REFLECTED TO THE V=R GUEST AFTER THE
              SYSTEM HAS RE-IPL'D.
              AT SYSTEM  TERMINATION TIME, HCPWRP  CALLS HCPMCWMD.
              HCPMCWMD GATHERS INFORMATION FROM THE INDIVIDUAL
              CPU MCVBK'S (AND OTHER SOURCES) AND PLACE IT IN THE
              SYSTEM TERMINATION MCVBKS (ONE SYSTEM TERMINATION
              MCVBK IS USED TO RECORD THE STATE OF ONE REAL CPU).
              AFTER THE SOFTWARE-RE-IPL THESE MCVBKS ARE PASSED
              TO HCPGMCGS SO THAT A MACHINE CHECK CAN BE
              REFLECTED TO THE V=R GUEST IF APPROPRIATE.

              HCPMPS   ACQUIRES PERMANENTLY ALLOCATED MCVBK FOR EACH

              HCPVOF   CREATES A CRW MCVBK.
              HCPVSC   CREATES A CRW MCVBK.
 DELETED BY : HCPMCH   DELETES MCVBKS CREATED BY HCPMCH
              HCPMCW   DELETES MCVBKS CREATED BY HCPMCW
              HCPMCV   DELETES MCVBK AFTER REFLECTING MACHINE CHECK TO THE
              GUEST
              HCPMPS   RETURNS  PERMANENTLY ALLOCATED MCVBK FOR EACH
              PROCESSOR.
 RELOCATION CONSIDERATIONS : This control block is relocated as part of a live
              guest relocation (LGR).  The bits and fields that
              need to be relocated are defined in the
              corresponding LGRMCVBK COPY file.  Whenever changes
              are made to this control block, consideration must
              be given to any effects these changes will have on
              a relocation.  If any new fields or bits are
              defined, they may need to be relocated.  If
              existing bits or fields are changed, corresponding
              modifications may be required in the LGR version of
              this control block.  Consider also the effects of
              these changes on a relocation involving a back-level
              release of CP.

MCVZNM1 IS FOR MCIC BITS 0-31. MCVZNM2 IS FOR MCIC BITS 32-63. These masks are used for different applications: 1. Constructing a guest MCIC. 2. Determining if all required bits are on in an MCIC to prevent the reporting of a system damage machine check. 3. Merging guest MCICs. Be sure to understand their use in each module prior to updating these masks definitions. A guest MCIC may need further manipulation to accurately reflect the guest's environment after it's initial setting or masking. (For example, some bits may need to be turned off if facilities are not available to the guest.)
