2.4.11 DVM messages

All slave interfaces on the CCI-550 support DVM messages. For ACE-Lite interfaces, this is through the addition of AC and CR channels. Each slave interface has a hardware enable input and programmable enable bit to determine whether it supports the issuing of AC requests for DVM messages.

The Snoop Control Registers and Control Override Register control DVM message requests.
Optionally, you can provide DVMv8.1 support by including the ARVMIDEXTSx and ACVMIDEXTSx signals in your configuration.

Note

A master that issues DVM messages must also be able to receive DVM messages. The slave interface through which the master connects must have DVM messages enabled.
