Detailed Description

This structure contains the global state of all command queues. It is stored in a bootmem named block and shared by all applications running on Octeon. Tickets are stored in a differnet cahce line that queue information to reduce the contention on the ll/sc used to get a ticket. If this is not the case, the update of queue state causes the ll/sc to fail quite often.
