agent_ccc0_ccc_active_vector_0
This register specifies which of the ACE masters are currently active and capable of receiving snoop requests. This register contains a bit vector where each bit corresponds to an ACE master bridge. The Bridge ID determines which bit corresponds to each bridge.
This vector can be used to disable snoop-only ACE agents, or to power off an ACE agent that may still have stale directory content. Note that ACE CPUs will often leave stale directory content.
A value of 1 indicates that the ACE agent is enabled and capable of accepting snoops. A value of 0 indicates that the ACE agent is disabled and snoops should not be sent. The default for this register is all ACE agents are active.
