*
* Support functions for managing command queues used for
* various hardware blocks.
*
* The common command queue infrastructure abstracts out the
* software necessary for adding to Octeon's chained queue
* structures. These structures are used for commands to the
* PKO, ZIP, DFA, RAID, HNA, 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. The wrappers perform
* unit specific validation and CSR writes to submit the
* commands.
*
* Even though most software will never directly interact with
* cvmx-cmd-queue, knowledge of its internal workings can help
* in diagnosing performance problems and help with debugging.
*
* Command queue pointers are stored in a global named block
* called "cvmx_cmd_queues". 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. When a core
* know it must wait in line for a lock, it spins on the
* internal cycle counter to completely eliminate any causes of
* bus traffic.

* Interface to the hardware Packet Output unit.
*
* Starting with SDK 1.7.0, the PKO output functions now support
* two types of locking. CVMX_PKO_LOCK_ATOMIC_TAG continues to
* function similarly to previous SDKs by using POW atomic tags
* to preserve ordering and exclusivity. As a new option, you
* can now pass CVMX_PKO_LOCK_CMD_QUEUE which uses a ll/sc
* memory based locking instead. This locking has the advantage
* of not affecting the tag state but doesn't preserve packet
* ordering. CVMX_PKO_LOCK_CMD_QUEUE is appropriate in most
* generic code while CVMX_PKO_LOCK_CMD_QUEUE should be used
* with hand tuned fast path code.
*
* Some of other SDK differences visible to the command command
* queuing:
* - PKO indexes are no longer stored in the FAU. A large
* percentage of the FAU register block used to be tied up
* maintaining PKO queue pointers. These are now stored in a
* global named block.
* - The PKO <b>use_locking</b> parameter can now have a global
* effect. Since all application use the same named block,
* queue locking correctly applies across all operating
* systems when using CVMX_PKO_LOCK_CMD_QUEUE.
* - PKO 3 word commands are now supported. Use
* cvmx_pko_send_packet_finish3().

* determine which OW pair gets the error by choosing the desired fill order
* (address<6:5>). A PL2 which hits in the L2 will not inject any errors.
* Therefore sending a WBIL2 prior to the PL2 is recommended to make a miss
* likely (if multiple processors are involved software must be careful to be
* sure no other processor or IO device can bring the block into the L2).
*
* To generate a VBFSBE or VBFDBE, software must first get the cache block
* into the cache with an error using a PL2 which misses the L2. Then a
* store partial to a portion of the cache block without the error must
* change the block to dirty. Then, a subsequent WBL2/WBIL2/victim will
* trigger the VBFSBE/VBFDBE error.
