These structures are used for commands to the + * PKO, ZIP, DFA, RAID, and DMA engine blocks. Although each + * hardware unit takes commands and CSRs of different types, + * they all use basic linked command buffers to store the + * pending request. In general, users of the CVMX API don't + * call cvmx-cmd-queue functions directly. Instead the hardware + * unit specific wrapper should be used.

Except for the PKO queues, each + * hardware queue is stored in its own cache line to reduce SMP + * contention on spin locks. The PKO queues are stored such that + * every 16th queue is next to each other in memory. This scheme + * allows for queues being in separate cache lines when there + * are low number of queues per port. With 16 queues per port, + * the first queue for each port is in the same cache area. The + * second queues for each port are in another area, etc. This + * allows software to implement very efficient lockless PKO with + * 16 queues per port using a minimum of cache lines per core. + * All queues for a given core will be isolated in the same + * cache area. + * + * In addition to the memory pointer layout, cvmx-cmd-queue + * provides an optimized fair ll/sc locking mechanism for the + * queues. The lock uses a "ticket / now serving" model to + * maintain fair order on contended locks. In addition, it uses + * predicted locking time to limit cache contention.
