DSECT NAME - MTRQDC
FUNCTION - Map a Monitor record.
LOCATED BY -
Through the Monitor Control Area
REFERENCED CONTROL BLOCKS -
MRRECHDR Monitor Record Header
NAME - MRMTRQDC
DESCRIPTIVE NAME - Monitor Sample Record
Domain 1 - Monitor Domain
Record 19 - QDIO Device Configuration
DESCRIPTION - Indicates configuration of a QDIO device.
NOTES -
1. This record is emitted for only real QDIO devices for which
z/VM CP is maintaining shadow queues. (If CP is not shadowing
the queues, it doesn't see the I/O and therefore can't emit
this record.) Typically Linux guests would use shadow queues
but z/VM TCP/IP would not. z/VM TCP/IP drives its real QDIO
devices using Diag X'98' and does not use shadow queues.
2. The byte count fields in this record are not correct
if the QDIO device is an FCP device. This is because
of limits in the FCP protocol.
