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.
