+/*
+ *
+ * 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, 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 working 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

-/*
- *
- * 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, 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 working 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().

-/**
- * Interface to the hardware Packet Order / Work unit.
- *
- * New, starting with SDK 1.7.0, cvmx-pow supports a number of
- * extended consistency checks. The define
- * CVMX_ENABLE_POW_CHECKS controls the runtime insertion of POW
- * internal state checks to find common programming errors. If
- * CVMX_ENABLE_POW_CHECKS is not defined, checks are by default
- * enabled. For example, cvmx-pow will check for the following
- * program errors or POW state inconsistency.
- * - Requesting a POW operation with an active tag switch in
- * progress.
- * - Waiting for a tag switch to complete for an excessively
- * long period. This is normally a sign of an error in locking
- * causing deadlock.
- * - Illegal tag switches from NULL_NULL.
- * - Illegal tag switches from NULL.
- * - Illegal deschedule request.
- * - WQE pointer not matching the one attached to the core by
- * the POW.
