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.
