This modification + was done for IP and L4. + * Added a new Rx LRO mbuf flag, used when packets are coalesced. This + flag indicates that the segment size of original packets is known. + +* **Added vhost-user dequeue zero copy support.** + + The copy in the dequeue path is avoided in order to improve the performance. + In the VM2VM case, the boost is quite impressive. The bigger the packet size, + the bigger performance boost you may get. However, for the VM2NIC case, there + are some limitations, so the boost is not as impressive as the VM2VM case. + It may even drop quite a bit for small packets. + + For that reason, this feature is disabled by default. It can be enabled when + the ``RTE_VHOST_USER_DEQUEUE_ZERO_COPY`` flag is set. Check the VHost section + of the Programming Guide for more information. + +* **Added vhost-user indirect descriptors support.** + + If the indirect descriptor feature is enabled, each packet sent by the guest + will take exactly one slot in the enqueue virtqueue. Without this feature, as in + the current version, even 64 bytes packets take two slots with Virtio PMD on guest + side. + + The main impact is better performance for 0% packet loss use-cases, as it + behaves as if the virtqueue size was enlarged, so more packets can be buffered + in the case of system perturbations. On the downside, small performance degradations + were measured when running micro-benchmarks. + +* **Added vhost PMD xstats.** + + Added extended statistics to vhost PMD from a per port perspective. + +* **Supported offloads with virtio.** + + Added support for the following offloads in virtio: + + * Rx/Tx checksums. + * LRO. + * TSO. + +* **Added virtio NEON support for ARM.** + + Added NEON support for ARM based virtio. + +* **Updated the ixgbe base driver.** + + Updated the ixgbe base driver, including the following changes: + + * Added X550em_a 10G PHY support. + * Added support for flow control auto negotiation for X550em_a 1G PHY. + * Added X550em_a FW ALEF support. + * Increased mailbox version to ``ixgbe_mbox_api_13``. + * Added two MAC operations for Hyper-V support. + +* **Added APIs for VF management to the ixgbe PMD.** + + Eight new APIs have been added to the ixgbe PMD for VF management from the PF. + The declarations for the API's can be found in ``rte_pmd_ixgbe.h``. + +* **Updated the enic driver.** + + * Added update to use interrupt for link status checking instead of polling. + * Added more flow director modes on UCS Blade with firmware version >= 2.0(13e). + * Added full support for MTU update. + * Added support for the ``rte_eth_rx_queue_count`` function. + +* **Updated the mlx5 driver.** + + * Added support for RSS hash results. + * Added several performance improvements. + * Added several bug fixes. + +* **Updated the QAT PMD.** + + The QAT PMD was updated with additional support for: + + * MD5_HMAC algorithm. + * SHA224-HMAC algorithm. + * SHA384-HMAC algorithm. + * GMAC algorithm. + * KASUMI (F8 and F9) algorithm. + * 3DES algorithm. + * NULL algorithm. + * C3XXX device. + * C62XX device. + +* **Added openssl PMD.** + + A new crypto PMD has been added, which provides several ciphering and hashing algorithms. + All cryptography operations use the Openssl library crypto API. + +* **Updated the IPsec example.** + + Updated the IPsec example with the following support: + + * Configuration file support. + * AES CBC IV generation with cipher forward function. + * AES GCM/CTR mode. + +* **Added support for new gcc -march option.** + + The GCC 4.9 ``-march`` option supports the Intel processor code names. + The config option ``RTE_MACHINE`` can be used to pass code names to the compiler via the ``-march`` flag. + + +Resolved Issues +--------------- + +..

Make sure to start the actual text at the margin. + +* **L3fwd-power app does not work properly when Rx vector is enabled.** + + The L3fwd-power app doesn't work properly with some drivers in vector mode + since the queue monitoring works differently between scalar and vector modes + leading to incorrect frequency scaling. In addition, L3fwd-power application + requires the mbuf to have correct packet type set but in some drivers the + vector mode must be disabled for this. + + Therefore, in order to use L3fwd-power, vector mode should be disabled + via the config file. + +* **Digest address must be supplied for crypto auth operation on QAT PMD.** + + The cryptodev API specifies that if the rte_crypto_sym_op.digest.data field, + and by inference the digest.phys_addr field which points to the same location, + is not set for an auth operation the driver is to understand that the digest + result is located immediately following the region over which the digest is + computed. The QAT PMD doesn't correctly handle this case and reads and writes + to an incorrect location. + + Callers can workaround this by always supplying the digest virtual and + physical address fields in the rte_crypto_sym_op for an auth operation. + + +API Changes +----------- + +..

For example + ``eth_pcap`` becomes ``net_pcap`` and ``cryptodev_aesni_mb_pmd`` becomes + ``crypto_aesni_mb``. + + For backward compatibility an alias feature has been enabled to support the + original names. + +* The log history has been removed. + +* The ``rte_ivshmem`` feature (including library and EAL code) has been removed + in 16.11 because it had some design issues which were not planned to be fixed. + +* The ``file_name`` data type of ``struct rte_port_source_params`` and + ``struct rte_port_sink_params`` is changed from ``char *`` to ``const char *``. + +* **Improved device/driver hierarchy and generalized hotplugging.** + + The device and driver relationship has been restructured by introducing generic + classes.

Common Issues -~~~~~~~~~~~~~ - -* QEMU failing to allocate memory on hugetlbfs, with an error like the following:: - - file_ram_alloc: can't mmap RAM pages: Cannot allocate memory - - When running QEMU the above error indicates that it has failed to allocate memory for the Virtual Machine on - the hugetlbfs. This is typically due to insufficient hugepages being free to support the allocation request. - The number of free hugepages can be checked as follows: - - .. code-block:: console - - cat /sys/kernel/mm/hugepages/hugepages-<pagesize>/nr_hugepages - - The command above indicates how many hugepages are free to support QEMU's allocation request. - -* User space VHOST when the guest has 2MB sized huge pages: - - The guest may have 2MB or 1GB sized huge pages. The user space VHOST should work properly in both cases. - -* User space VHOST will not work with QEMU without the ``-mem-prealloc`` option: - - The current implementation works properly only when the guest memory is pre-allocated, so it is required to - use a QEMU version (e.g. 1.6) which supports ``-mem-prealloc``. The ``-mem-prealloc`` option must be - specified explicitly in the QEMU command line. - -* User space VHOST will not work with a QEMU version without shared memory mapping: - - As shared memory mapping is mandatory for user space VHOST to work properly with the guest, user space VHOST - needs access to the shared memory from the guest to receive and transmit packets. It is important to make sure - the QEMU version supports shared memory mapping. - -* In an Ubuntu environment, QEMU fails to start a new guest normally with user space VHOST due to not being able - to allocate huge pages for the new guest: - - The solution for this issue is to add ``-boot c`` into the QEMU command line to make sure the huge pages are - allocated properly and then the guest should start normally. - - Use ``cat /proc/meminfo`` to check if there is any changes in the value of ``HugePages_Total`` and ``HugePages_Free`` - after the guest startup. - -* Log message: ``eventfd_link: module verification failed: signature and/or required key missing - tainting kernel``: - - This log message may be ignored. The message occurs due to the kernel module ``eventfd_link``, which is not a standard - Linux module but which is necessary for the user space VHOST current implementation (CUSE-based) to communicate with - the guest. - -.. _vhost_app_running_dpdk: - -Running DPDK in the Virtual Machine ------------------------------------ - -For the DPDK vhost-net sample code to switch packets into the VM, -the sample code must first learn the MAC address of the VM's virtio-net device. -The sample code detects the address from packets being transmitted from the VM, similar to a learning switch. - -This behavior requires no special action or configuration with the Linux* virtio-net driver in the VM -as the Linux* Kernel will automatically transmit packets during device initialization. -However, DPDK-based applications must be modified to automatically transmit packets during initialization -to facilitate the DPDK vhost- net sample code's MAC learning. - -The DPDK testpmd application can be configured to automatically transmit packets during initialization -and to act as an L2 forwarding switch. - -Testpmd MAC Forwarding -~~~~~~~~~~~~~~~~~~~~~~ - -At high packet rates, a minor packet loss may be observed. -To resolve this issue, a "wait and retry" mode is implemented in the testpmd and vhost sample code. -In the "wait and retry" mode if the virtqueue is found to be full, then testpmd waits for a period of time before retrying to enqueue packets. - -The "wait and retry" algorithm is implemented in DPDK testpmd as a forwarding method call "mac_retry". -The following sequence diagram describes the algorithm in detail. - -.. _figure_tx_dpdk_testpmd: - -.. figure:: img/tx_dpdk_testpmd.* - - Packet Flow on TX in DPDK-testpmd - - -Running Testpmd -~~~~~~~~~~~~~~~ - -The testpmd application is automatically built when DPDK is installed. -Run the testpmd application as follows: - -.. code-block:: console - - cd ${RTE_SDK}/x86_64-native-linuxapp-gcc/app - ./testpmd -c 0x3 -n 4 --socket-mem 512 \ - -- --burst=64 --i --disable-hw-vlan-filter - -The destination MAC address for packets transmitted on each port can be set at the command line: - -.. code-block:: console - - ./testpmd -c 0x3 -n 4 --socket-mem 512 \ - -- --burst=64 --i --disable-hw-vlan-filter \ - --eth-peer=0,aa:bb:cc:dd:ee:ff --eth-peer=1,ff:ee:dd:cc:bb:aa - -* Packets received on port 1 will be forwarded on port 0 to MAC address - - aa:bb:cc:dd:ee:ff - -* Packets received on port 0 will be forwarded on port 1 to MAC address - - ff:ee:dd:cc:bb:aa - -The testpmd application can then be configured to act as an L2 forwarding application: - -.. code-block:: console - - testpmd> set fwd mac_retry - -The testpmd can then be configured to start processing packets, -transmitting packets first so the DPDK vhost sample code on the host can learn the MAC address: - -.. code-block:: console - - testpmd> start tx_first +------------- -.. note:: +* QEMU fails to allocate memory on hugetlbfs, with an error like the + following:: - Please note "set fwd mac_retry" is used in place of "set fwd mac_fwd" to ensure the retry feature is activated. + file_ram_alloc: can't mmap RAM pages: Cannot allocate memory -Passing Traffic to the Virtual Machine Device ---------------------------------------------- + When running QEMU the above error indicates that it has failed to allocate + memory for the Virtual Machine on the hugetlbfs.
