3.17.3 Changing the Routing table owner

You can change the chip that owns the Routing table at any time.

A procedure that describes how to change the owner of the Routing table is as follows.

To change the owner of the Routing table:

  1. Write to GICD_DCHIPR.rt_owner, where the value of the rt_owner is the chip_id of the new owner.
  2. Poll for GICD_DCHIPR.PUP == 0.

The Routing table owner must be the last chip to be powered down.
