[cavium-octeon] add support for the Cavium Octeon SoC, tested on a Mototech evaluatio...

[openwrt.git] / target / linux / cavium-octeon / patches / 011-octeon_ethernet_driver.patch

The octeon-ethernet driver supports the sgmii, rgmii, spi, and xaui
ports present on the Cavium OCTEON family of SOCs.  These SOCs are
multi-core mips64 processors with existing support over in arch/mips.

The driver files can be categorized into three basic groups:

1) Register definitions, these are named cvmx-*-defs.h

2) Main driver code, these have names that don't start cvmx-.

3) Interface specific functions and other utility code, names starting
with cvmx-

+/*
+ *
+ * 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.

+/*
+ * 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.
