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.
