++/*
++ *
++ * 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().

++/*
++ * A few defines are used to control the operation of this driver:
++ *  CONFIG_CAVIUM_RESERVE32
++ *      This kernel config options controls the amount of memory configured
++ *      in a wired TLB entry for all processes to share. If this is set, the
++ *      driver will use this memory instead of kernel memory for pools. This
++ *      allows 32bit userspace application to access the buffers, but also
++ *      requires all received packets to be copied.
++ *  CONFIG_CAVIUM_OCTEON_NUM_PACKET_BUFFERS
++ *      This kernel config option allows the user to control the number of
++ *      packet and work queue buffers allocated by the driver. If this is zero,
++ *      the driver uses the default from below.
++ *  USE_SKBUFFS_IN_HW
++ *      Tells the driver to populate the packet buffers with kernel skbuffs.
++ *      This allows the driver to receive packets without copying them. It also
++ *      means that 32bit userspace can't access the packet buffers.
++ *  USE_32BIT_SHARED
++ *      This define tells the driver to allocate memory for buffers from the
++ *      32bit sahred region instead of the kernel memory space.
++ *  USE_HW_TCPUDP_CHECKSUM
++ *      Controls if the Octeon TCP/UDP checksum engine is used for packet
++ *      output. If this is zero, the kernel will perform the checksum in
++ *      software.
++ *  USE_MULTICORE_RECEIVE
++ *      Process receive interrupts on multiple cores. This spreads the network
++ *      load across the first 8 processors. If ths is zero, only one core
++ *      processes incomming packets.
++ *  USE_ASYNC_IOBDMA
++ *      Use asynchronous IO access to hardware. This uses Octeon's asynchronous
++ *      IOBDMAs to issue IO accesses without stalling. Set this to zero
++ *      to disable this. Note that IOBDMAs require CVMSEG.
++ *  REUSE_SKBUFFS_WITHOUT_FREE
++ *      Allows the TX path to free an skbuff into the FPA hardware pool. This
++ *      can significantly improve performance for forwarding and bridging, but
++ *      may be somewhat dangerous. Checks are made, but if any buffer is reused
++ *      without the proper Linux cleanup, the networking stack may have very
++ *      bizarre bugs.
