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. ++ * ++ */ ++ ++#ifndef __CVMX_CMD_QUEUE_H__ ++#define __CVMX_CMD_QUEUE_H__ ++ ++#include <linux/prefetch.h> ++ ++#include "cvmx-fpa.h" ++/** ++ * By default we disable the max depth support.

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.
