VDEV Prolog
NAME : HCPVDEV
DESCRIPTION: VIRTUAL DEVICE CONTROL BLOCK
DSECT : VDEV
FUNCTION : DESCRIBE THE STATUS OF AN I/O DEVICE (REAL OR VIRTUAL)
ACCESSABLE BY A VIRTUAL MACHINE.
LOCATED BY - A POINTER IN THE LOWEST LEVEL INDEX VECTOR IN THE
FOUR-LEVEL TREE ANCHORED IN:
VMDCHRSN - FOR ACCESS VIA SUBCHANNEL NUMBER
VMDCHRDN - FOR ACCESS VIA DEVICE NUMBER
RDEVVDEV - DEDICATED DEVICE ONLY
BLKVDEVA - DEVICES CONNECTED TO DASD BLOCK I/O
SYSTEM SERVICE
VMDVSPRT - PRINTER TO USE IN DUMP, TRACE, ... CMDS
VMDVCONS - CONSOLE
MDIRVDEV - VDEV TO WHICH A MINI-DISK EXTENT IS
VIRTUALLY RESERVED.
WHILE AN I/O EVENT IS OUTSTANDING FOR A VIRTUAL
MACHINE, THE ADDRESS OF A VDEV MAY APPEAR IN:
CHCQUEUE(I) - FIRST DEVICE WITH AN INTERRUPT PENDING
ON CHANNEL I (OR IN CHANNEL CLASS I)
VDEVFPNT - NEXT DEVICE WITH INTERRUPT PENDING ON
THIS CHANNEL (OR THIS VDEV, IF LAST)
VDEVBPNT - PREVIOUS INTERRUPT PENDING DEVICE ON THIS
CHANNEL (OR THIS VDEV, IF FIRST)
VMDWVDEV - DEVICE CAUSING I/O WAIT CONDITION
- SYNCHRONOUS I/O VIA DIAGNOSE 18 OR 20
- VIRTUAL MACHINE LOOPING ON TIO INSTR.
IORVDEV - VDEV WITH WHICH VIRTUAL MACHINE'S I/O
REQUEST IS ASSOCIATED.
WHEN A GUEST REQUESTS AN ASYNCHRONOUS MESSAGE,
THE ADDRESS OF A VDEV MAY APPEAR IN:
AEBKVDEV - VDEV WITH WHICH VIRTUAL MACHINE'S
ASYNCHRONOUS MESSAGE REQUEST IS
ASSOCIATED.
I/O SUPERVISOR ROUTINES NORMALLY USE REGISTER 6 TO
ADDRESS THE VDEV ASSOCIATED WITH THE EVENT BEING
PROCESSED.

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 LGRVDEV 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.
