brcm63xx: add support for linux 3.2
[openwrt.git] / target / linux / octeon / patches-2.6.30 / 011-octeon_ethernet_driver.patch
1 The octeon-ethernet driver supports the sgmii, rgmii, spi, and xaui
2 ports present on the Cavium OCTEON family of SOCs. These SOCs are
3 multi-core mips64 processors with existing support over in arch/mips.
4
5 The driver files can be categorized into three basic groups:
6
7 1) Register definitions, these are named cvmx-*-defs.h
8
9 2) Main driver code, these have names that don't start cvmx-.
10
11 3) Interface specific functions and other utility code, names starting
12 with cvmx-

1308 +/*
1309 + *
1310 + * Support functions for managing command queues used for
1311 + * various hardware blocks.
1312 + *
1313 + * The common command queue infrastructure abstracts out the
1314 + * software necessary for adding to Octeon's chained queue
1315 + * structures. These structures are used for commands to the
1316 + * PKO, ZIP, DFA, RAID, and DMA engine blocks. Although each
1317 + * hardware unit takes commands and CSRs of different types,
1318 + * they all use basic linked command buffers to store the
1319 + * pending request. In general, users of the CVMX API don't
1320 + * call cvmx-cmd-queue functions directly. Instead the hardware
1321 + * unit specific wrapper should be used. The wrappers perform
1322 + * unit specific validation and CSR writes to submit the
1323 + * commands.
1324 + *
1325 + * Even though most software will never directly interact with
1326 + * cvmx-cmd-queue, knowledge of its internal working can help
1327 + * in diagnosing performance problems and help with debugging.
1328 + *
1329 + * Command queue pointers are stored in a global named block
1330 + * called "cvmx_cmd_queues". Except for the PKO queues, each
1331 + * hardware queue is stored in its own cache line to reduce SMP
1332 + * contention on spin locks. The PKO queues are stored such that
1333 + * every 16th queue is next to each other in memory. This scheme
1334 + * allows for queues being in separate cache lines when there
1335 + * are low number of queues per port. With 16 queues per port,
1336 + * the first queue for each port is in the same cache area. The
1337 + * second queues for each port are in another area, etc. This
1338 + * allows software to implement very efficient lockless PKO with
1339 + * 16 queues per port using a minimum of cache lines per core.
1340 + * All queues for a given core will be isolated in the same
1341 + * cache area.
1342 + *
1343 + * In addition to the memory pointer layout, cvmx-cmd-queue
1344 + * provides an optimized fair ll/sc locking mechanism for the
1345 + * queues. The lock uses a "ticket / now serving" model to
1346 + * maintain fair order on contended locks. In addition, it uses
1347 + * predicted locking time to limit cache contention. When a core
1348 + * know it must wait in line for a lock, it spins on the
1349 + * internal cycle counter to completely eliminate any causes of
1350 + * bus traffic.

17292 +/**
17293 + *
17294 + * Interface to the hardware Packet Output unit.
17295 + *
17296 + * Starting with SDK 1.7.0, the PKO output functions now support
17297 + * two types of locking. CVMX_PKO_LOCK_ATOMIC_TAG continues to
17298 + * function similarly to previous SDKs by using POW atomic tags
17299 + * to preserve ordering and exclusivity. As a new option, you
17300 + * can now pass CVMX_PKO_LOCK_CMD_QUEUE which uses a ll/sc
17301 + * memory based locking instead. This locking has the advantage
17302 + * of not affecting the tag state but doesn't preserve packet
17303 + * ordering. CVMX_PKO_LOCK_CMD_QUEUE is appropriate in most
17304 + * generic code while CVMX_PKO_LOCK_CMD_QUEUE should be used
17305 + * with hand tuned fast path code.
17306 + *
17307 + * Some of other SDK differences visible to the command command
17308 + * queuing:
17309 + * - PKO indexes are no longer stored in the FAU. A large
17310 + * percentage of the FAU register block used to be tied up
17311 + * maintaining PKO queue pointers. These are now stored in a
17312 + * global named block.
17313 + * - The PKO <b>use_locking</b> parameter can now have a global
17314 + * effect. Since all application use the same named block,
17315 + * queue locking correctly applies across all operating
17316 + * systems when using CVMX_PKO_LOCK_CMD_QUEUE.
17317 + * - PKO 3 word commands are now supported. Use
17318 + * cvmx_pko_send_packet_finish3().
17319 + *

17907 + *
17908 + * New, starting with SDK 1.7.0, cvmx-pow supports a number of
17909 + * extended consistency checks. The define

17911 + * internal state checks to find common programming errors. If
17912 + * CVMX_ENABLE_POW_CHECKS is not defined, checks are by default
17913 + * enabled. For example, cvmx-pow will check for the following
17914 + * program errors or POW state inconsistency.
17915 + * - Requesting a POW operation with an active tag switch in
17916 + * progress.
17917 + * - Waiting for a tag switch to complete for an excessively
17918 + * long period. This is normally a sign of an error in locking
17919 + * causing deadlock.
17920 + * - Illegal tag switches from NULL_NULL.
17921 + * - Illegal tag switches from NULL.
17922 + * - Illegal deschedule request.
17923 + * - WQE pointer not matching the one attached to the core by
17924 + * the POW.

22693 + * A few defines are used to control the operation of this driver:
22694 + * CONFIG_CAVIUM_RESERVE32
22695 + * This kernel config options controls the amount of memory configured
22696 + * in a wired TLB entry for all processes to share. If this is set, the
22697 + * driver will use this memory instead of kernel memory for pools. This
22698 + * allows 32bit userspace application to access the buffers, but also
22699 + * requires all received packets to be copied.
22700 + * CONFIG_CAVIUM_OCTEON_NUM_PACKET_BUFFERS
22701 + * This kernel config option allows the user to control the number of
22702 + * packet and work queue buffers allocated by the driver. If this is zero,
22703 + * the driver uses the default from below.
22704 + * USE_SKBUFFS_IN_HW
22705 + * Tells the driver to populate the packet buffers with kernel skbuffs.
22706 + * This allows the driver to receive packets without copying them. It also
22707 + * means that 32bit userspace can't access the packet buffers.
22708 + * USE_32BIT_SHARED
22709 + * This define tells the driver to allocate memory for buffers from the
22710 + * 32bit sahred region instead of the kernel memory space.
22711 + * USE_HW_TCPUDP_CHECKSUM
22712 + * Controls if the Octeon TCP/UDP checksum engine is used for packet
22713 + * output. If this is zero, the kernel will perform the checksum in
22714 + * software.
22715 + * USE_MULTICORE_RECEIVE
22716 + * Process receive interrupts on multiple cores. This spreads the network
22717 + * load across the first 8 processors. If ths is zero, only one core
22718 + * processes incomming packets.
22719 + * USE_ASYNC_IOBDMA
22720 + * Use asynchronous IO access to hardware. This uses Octeon's asynchronous
22721 + * IOBDMAs to issue IO accesses without stalling. Set this to zero
22722 + * to disable this. Note that IOBDMAs require CVMSEG.
22723 + * REUSE_SKBUFFS_WITHOUT_FREE
22724 + * Allows the TX path to free an skbuff into the FPA hardware pool. This
22725 + * can significantly improve performance for forwarding and bridging, but
22726 + * may be somewhat dangerous. Checks are made, but if any buffer is reused
22727 + * without the proper Linux cleanup, the networking stack may have very
22728 + * bizarre bugs.
