SDRAM Memory Scheduler Firewall Configuration

Hi,

I'm trying to configure the SMS Firewall to prevent the IVA2.2 Subsystem from accessing DRAM outside of a specific range. 

The read and write permission registers (SMS_RG_RDPERMi, SMS_RG_WRPERMi) require the connection ID to be specified for each allowed initiator. 

Where are these connection IDs defined?

Thanks,

-Kevin
