|
* RTE Ethernet Device API
|
|
|
|
*
|
|
|
|
* The Ethernet Device API is composed of two parts:
|
|
|
|
*
|
|
|
|
* - The application-oriented Ethernet API that includes functions to setup
|
|
|
|
* an Ethernet device (configure it, setup its RX and TX queues and start it),
|
|
|
|
* to get its MAC address, the speed and the status of its physical link,
|
|
|
|
* to receive and to transmit packets, and so on.
|
|
|
|
*
|
|
|
|
* - The driver-oriented Ethernet API that exports a function allowing
|
|
|
|
* an Ethernet Poll Mode Driver (PMD) to simultaneously register itself as
|
|
|
|
* an Ethernet device driver and as a PCI driver for a set of matching PCI
|
|
|
|
* [Ethernet] devices classes.
|
|
|
|
*
|
|
|
|
* By default, all the functions of the Ethernet Device API exported by a PMD
|
|
|
|
* are lock-free functions which assume to not be invoked in parallel on
|
|
|
|
* different logical cores to work on the same target object. For instance,
|
|
|
|
* the receive function of a PMD cannot be invoked in parallel on two logical
|
|
|
|
* cores to poll the same RX queue [of the same port]. Of course, this function
|
|
|
|
* can be invoked in parallel by different logical cores on different RX queues.
|
|
|
|
* It is the responsibility of the upper level application to enforce this rule.
|
|
|
|
*
|
|
|
|
* If needed, parallel accesses by multiple logical cores to shared queues
|
|
|
|
* shall be explicitly protected by dedicated inline lock-aware functions
|
|
|
|
* built on top of their corresponding lock-free functions of the PMD API.
|
|
|
|
*
|
|
|
|
* In all functions of the Ethernet API, the Ethernet device is
|
|
|
|
* designated by an integer >= 0 named the device port identifier.
|
|
|
|
*
|
|
|
|
* At the Ethernet driver level, Ethernet devices are represented by a generic
|
|
|
|
* data structure of type *rte_eth_dev*.
|
|
|
|
*
|
|
|
|
* Ethernet devices are dynamically registered during the PCI probing phase
|
|
|
|
* performed at EAL initialization time.
|
|
|
|
* When an Ethernet device is being probed, an *rte_eth_dev* structure and
|
|
|
|
* a new port identifier are allocated for that device. Then, the eth_dev_init()
|
|
|
|
* function supplied by the Ethernet driver matching the probed PCI
|
|
|
|
* device is invoked to properly initialize the device.
|
|
|
|
*
|
|
|
|
* The role of the device init function consists of resetting the hardware,
|
|
|
|
* checking access to Non-volatile Memory (NVM), reading the MAC address
|
|
|
|
* from NVM etc.
|
|
|
|
*
|
|
|
|
* If the device init operation is successful, the correspondence between
|
|
|
|
* the port identifier assigned to the new device and its associated
|
|
|
|
* *rte_eth_dev* structure is effectively registered.
|
|
|
|
* Otherwise, both the *rte_eth_dev* structure and the port identifier are
|
|
|
|
* freed.
|
|
|
|
*
|
|
|
|
* The functions exported by the application Ethernet API to setup a device
|
|
|
|
* designated by its port identifier must be invoked in the following order:
|
|
|
|
* - rte_eth_dev_configure()
|
|
|
|
* - rte_eth_tx_queue_setup()
|
|
|
|
* - rte_eth_rx_queue_setup()
|
|
|
|
* - rte_eth_dev_start()
|
|
|
|
*
|
|
|
|
* Then, the network application can invoke, in any order, the functions
|
|
|
|
* exported by the Ethernet API to get the MAC address of a given device, to
|
|
|
|
* get the speed and the status of a device physical link, to receive/transmit
|
|
|
|
* [burst of] packets, and so on.
|
|
|
|
*
|
|
|
|
* If the application wants to change the configuration (i.e. call
|
|
|
|
* rte_eth_dev_configure(), rte_eth_tx_queue_setup(), or
|
|
|
|
* rte_eth_rx_queue_setup()), it must call rte_eth_dev_stop() first to stop the
|
|
|
|
* device and then do the reconfiguration before calling rte_eth_dev_start()
|
|
|
|
* again. The tramsit and receive functions should not be invoked when the
|
|
|
|
* device is stopped.
|
|
|
|
*
|
|
|
|
* Please note that some configuration is not stored between calls to
|
|
|
|
* rte_eth_dev_stop()/rte_eth_dev_start(). The following configuration will
|
|
|
|
* be retained:
|
|
|
|
*
|
|
|
|
* - flow control settings
|
|
|
|
* - receive mode configuration (promiscuous mode, hardware checksum mode,
|
|
|
|
* RSS/VMDQ settings etc.)
|
|
|
|
* - VLAN filtering configuration
|
|
|
|
* - MAC addresses supplied to MAC address array
|
|
|
|
* - flow director filtering mode (but not filtering rules)
|
2012-12-19 23:00:00 +00:00
|
|
|
* - NIC queue statistics mappings
|
2012-09-04 12:54:00 +00:00
|
|
|
*
|
|
|
|
* Any other configuration will not be stored and will need to be re-entered
|
|
|
|
* after a call to rte_eth_dev_start().
|
|
|
|
*
|
|
|
|
* Finally, a network application can close an Ethernet device by invoking the
|
|
|
|
* rte_eth_dev_close() function.
|
|
|
|
*
|
|
|
|
* Each function of the application Ethernet API invokes a specific function
|
|
|
|
* of the PMD that controls the target device designated by its port
|
|
|
|
* identifier.
|
|
|
|
* For this purpose, all device-specific functions of an Ethernet driver are
|
|
|
|
* supplied through a set of pointers contained in a generic structure of type
|
|
|
|
* *eth_dev_ops*.
|
|
|
|
* The address of the *eth_dev_ops* structure is stored in the *rte_eth_dev*
|
|
|
|
* structure by the device init function of the Ethernet driver, which is
|
|
|
|
* invoked during the PCI probing phase, as explained earlier.
|
|
|
|
*
|
|
|
|
* In other words, each function of the Ethernet API simply retrieves the
|
|
|
|
* *rte_eth_dev* structure associated with the device port identifier and
|
|
|
|
* performs an indirect invocation of the corresponding driver function
|
|
|
|
* supplied in the *eth_dev_ops* structure of the *rte_eth_dev* structure.
|
|
|
|
*
|
|
|
|
* For performance reasons, the address of the burst-oriented RX and TX
|
|
|
|
* functions of the Ethernet driver are not contained in the *eth_dev_ops*
|
|
|
|
* structure. Instead, they are directly stored at the beginning of the
|
|
|
|
* *rte_eth_dev* structure to avoid an extra indirect memory access during
|
|
|
|
* their invocation.
|
|
|
|
*
|
|
|
|
* RTE ethernet device drivers do not use interrupts for transmitting or
|
|
|
|
* receiving. Instead, Ethernet drivers export Poll-Mode receive and transmit
|
|
|
|
* functions to applications.
|
|
|
|
* Both receive and transmit functions are packet-burst oriented to minimize
|
|
|
|
* their cost per packet through the following optimizations:
|
|
|
|
*
|
|
|
|
* - Sharing among multiple packets the incompressible cost of the
|
|
|
|
* invocation of receive/transmit functions.
|
|
|
|
*
|
|
|
|
* - Enabling receive/transmit functions to take advantage of burst-oriented
|
|
|
|
* hardware features (L1 cache, prefetch instructions, NIC head/tail
|
|
|
|
* registers) to minimize the number of CPU cycles per packet, for instance,
|
|
|
|
* by avoiding useless read memory accesses to ring descriptors, or by
|
|
|
|
* systematically using arrays of pointers that exactly fit L1 cache line
|
|
|
|
* boundaries and sizes.
|
|
|
|
*
|
|
|
|
* The burst-oriented receive function does not provide any error notification,
|
|
|
|
* to avoid the corresponding overhead. As a hint, the upper-level application
|
|
|
|
* might check the status of the device link once being systematically returned
|
|
|
|
* a 0 value by the receive function of the driver for a given number of tries.

|
|

|
|
|
|
*
|
|
|
|
* The rte_eth_rx_burst() function loops, parsing the RX ring of the
|
|
|
|
* receive queue, up to *nb_pkts* packets, and for each completed RX
|
|
|
|
* descriptor in the ring, it performs the following operations:
|
|
|
|
*
|
|
|
|
* - Initialize the *rte_mbuf* data structure associated with the
|
|
|
|
* RX descriptor according to the information provided by the NIC into
|
|
|
|
* that RX descriptor.
|
|
|
|
*
|
|
|
|
* - Store the *rte_mbuf* data structure into the next entry of the
|
|
|
|
* *rx_pkts* array.
|
|
|
|
*
|
|
|
|
* - Replenish the RX descriptor with a new *rte_mbuf* buffer
|
|
|
|
* allocated from the memory pool associated with the receive queue at
|
|
|
|
* initialization time.
|
|
|
|
*
|
|
|
|
* When retrieving an input packet that was scattered by the controller
|
|
|
|
* into multiple receive descriptors, the rte_eth_rx_burst() function
|
|
|
|
* appends the associated *rte_mbuf* buffers to the first buffer of the
|
|
|
|
* packet.
|
|
|
|
*
|
|
|
|
* The rte_eth_rx_burst() function returns the number of packets
|
|
|
|
* actually retrieved, which is the number of *rte_mbuf* data structures
|
|
|
|
* effectively supplied into the *rx_pkts* array.
|
|
|
|
* A return value equal to *nb_pkts* indicates that the RX queue contained
|
|
|
|
* at least *rx_pkts* packets, and this is likely to signify that other
|
|
|
|
* received packets remain in the input queue. Applications implementing
|
|
|
|
* a "retrieve as much received packets as possible" policy can check this
|
|
|
|
* specific case and keep invoking the rte_eth_rx_burst() function until
|
|
|
|
* a value less than *nb_pkts* is returned.
|
|
|
|
*
|
|
|
|
* This receive method has the following advantages:
|
|
|
|
*
|
|
|
|
* - It allows a run-to-completion network stack engine to retrieve and
|
|
|
|
* to immediately process received packets in a fast burst-oriented
|
|
|
|
* approach, avoiding the overhead of unnecessary intermediate packet
|
|
|
|
* queue/dequeue operations.
|
|
|
|
*
|
|
|
|
* - Conversely, it also allows an asynchronous-oriented processing
|
|
|
|
* method to retrieve bursts of received packets and to immediately
|
|
|
|
* queue them for further parallel processing by another logical core,
|
|
|
|
* for instance. However, instead of having received packets being
|
|
|
|
* individually queued by the driver, this approach allows the invoker
|
|
|
|
* of the rte_eth_rx_burst() function to queue a burst of retrieved
|
|
|
|
* packets at a time and therefore dramatically reduce the cost of
|
|
|
|
* enqueue/dequeue operations per packet.
|
|
|
|
*
|
|
|
|
* - It allows the rte_eth_rx_burst() function of the driver to take
|
|
|
|
* advantage of burst-oriented hardware features (CPU cache,
|
|
|
|
* prefetch instructions, and so on) to minimize the number of CPU
|
|
|
|
* cycles per packet.
|
|
|
|
*
|
|
|
|
* To summarize, the proposed receive API enables many
|
|
|
|
* burst-oriented optimizations in both synchronous and asynchronous
|
|
|
|
* packet processing environments with no overhead in both cases.
|
|
|
|
*
|
|
|
|
* The rte_eth_rx_burst() function does not provide any error
|
|
|
|
* notification to avoid the corresponding overhead. As a hint, the
|
|
|
|
* upper-level application might check the status of the device link once
|
|
|
|
* being systematically returned a 0 value for a given number of tries.

/**
|
|
|
|
* Send a burst of output packets on a transmit queue of an Ethernet device.
|
|
|
|
*
|
|
|
|
* The rte_eth_tx_burst() function is invoked to transmit output packets
|
|
|
|
* on the output queue *queue_id* of the Ethernet device designated by its
|
|
|
|
* *port_id*.
|
|
|
|
* The *nb_pkts* parameter is the number of packets to send which are
|
|
|
|
* supplied in the *tx_pkts* array of *rte_mbuf* structures.
|
|
|
|
* The rte_eth_tx_burst() function loops, sending *nb_pkts* packets,
|
|
|
|
* up to the number of transmit descriptors available in the TX ring of the
|
|
|
|
* transmit queue.
|
|
|
|
* For each packet to send, the rte_eth_tx_burst() function performs
|
|
|
|
* the following operations:
|
|
|
|
*
|
|
|
|
* - Pick up the next available descriptor in the transmit ring.
|
|
|
|
*
|
|
|
|
* - Free the network buffer previously sent with that descriptor, if any.
|
|
|
|
*
|
|
|
|
* - Initialize the transmit descriptor with the information provided
|
|
|
|
* in the *rte_mbuf data structure.
|
|
|
|
*
|
|
|
|
* In the case of a segmented packet composed of a list of *rte_mbuf* buffers,
|
|
|
|
* the rte_eth_tx_burst() function uses several transmit descriptors
|
|
|
|
* of the ring.
|
|
|
|
*
|
|
|
|
* The rte_eth_tx_burst() function returns the number of packets it
|
|
|
|
* actually sent. A return value equal to *nb_pkts* means that all packets
|
|
|
|
* have been sent, and this is likely to signify that other output packets
|
|
|
|
* could be immediately transmitted again. Applications that implement a
|
|
|
|
* "send as many packets to transmit as possible" policy can check this
|
|
|
|
* specific case and keep invoking the rte_eth_tx_burst() function until
|
|
|
|
* a value less than *nb_pkts* is returned.
|
|
|
|
*
|
|
|
|
* It is the responsibility of the rte_eth_tx_burst() function to
|
|
|
|
* transparently free the memory buffers of packets previously sent.
|
|
|
|
* This feature is driven by the *tx_free_thresh* value supplied to the
|
|
|
|
* rte_eth_dev_configure() function at device configuration time.
|
2015-06-23 18:43:12 +00:00
|
|
|
* When the number of free TX descriptors drops below this threshold, the
|
|
|
|
* rte_eth_tx_burst() function must [attempt to] free the *rte_mbuf* buffers
|
|
|
|
* of those packets whose transmission was effectively completed.
