Initiator-Side Security Control (ISC) modules are hosted at the initiator side where the transactions are sourced. ISC controls the security sideband attributes that are applied to outgoing transactions and have ability to override security values under exclusive control of DMSC.
ISC Capabilities:
ISCs are connected to the dedicated security VBUSP interconnect and can be exclusively configured by DMSC. ISC optionally can support region and channel number based security control, where, based on incoming channel or address, the associated security controls, are applied.
Figure 3-3 presents ISC config registers per region.
Priv-ID is used to identify the logical source of transaction and is attached by ISC. The Priv-IDs are allocated based on subsystem as part of platform definition.
