z/VM recording device driver
The z/VM recording device driver enables Linux® on z/VM to read from the CP recording services and, thus, act as a z/VM wide control point.
The z/VM recording device driver uses the z/VM CP RECORDING command to collect records and IUCV to transmit them to the Linux instance.
For general information about CP recording system services, see z/VM: CP Programming Services, SC24-6272.
