Rather than using linuxapp and bsdapp everywhere, we can change things to use the, more readable, terms "linux" and "freebsd" in our build configs. Rather than renaming the configs we can just duplicate the existing ones with the new names using symlinks, and use the new names exclusively internally. ["make showconfigs" also only shows the new names to keep the list short] The result is that backward compatibility is kept fully but any new builds or development can be done using the newer names, i.e. both "make config T=x86_64-native-linuxapp-gcc" and "T=x86_64-native-linux-gcc" work.

DPDK Release 2.1
|
|
================
|
|
|
|
|
|
New Features
|
|
------------
|
|
|
|
* **Enabled cloning of indirect mbufs.**
|
|
|
|
This feature removes a limitation of ``rte_pktmbuf_attach()`` which
|
|
generated the warning: "mbuf we're attaching to must be direct".
|
|
|
|
Now, when attaching to an indirect mbuf it is possible to:
|
|
|
|
* Copy all relevant fields (address, length, offload, ...) as before.
|
|
|
|
* Get the pointer to the mbuf that embeds the data buffer (direct mbuf),
|
|
and increase the reference counter.
|
|
|
|
When detaching the mbuf, we can now retrieve this direct mbuf as the
|
|
pointer is determined from the buffer address.
|
|
|
|
|
|
* **Extended packet type support.**
|
|
|
|
In previous releases mbuf packet types were indicated by 6 bits in the
|
|
``ol_flags``. This was not enough for some supported NICs. For example i40e
|
|
hardware can recognize more than 150 packet types. Not being able to
|
|
identify these additional packet types limits access to hardware offload
|
|
capabilities
|
|
|
|
So an extended "unified" packet type was added to support all possible
|
|
PMDs. The 16 bit packet_type in the mbuf structure was changed to 32 bits
|
|
and used for this purpose.
|
|
|
|
To avoid breaking ABI compatibility, the code changes for this feature are
|
|
enclosed in a ``RTE_NEXT_ABI`` ifdef. This is enabled by default but can be
|
|
turned off for ABI compatibility with DPDK R2.0.
|
|
|
|
|
|
* **Reworked memzone to be allocated by malloc and also support freeing.**
|
|
|
|
In the memory hierarchy, memsegs are groups of physically contiguous
|
|
hugepages, memzones are slices of memsegs, and malloc slices memzones
|
|
into smaller memory chunks.
|
|
|
|
This feature modifies ``malloc()`` so it partitions memsegs instead of
|
|
memzones. Now memzones allocate their memory from the malloc heap.
|
|
|
|
Backward compatibility with API and ABI are maintained.
|
|
|
|
This allow memzones, and any other structure based on memzones, for example
|
|
mempools, to be freed. Currently only the API from freeing memzones is
|
|
supported.
|
|
|
|
|
|
* **Interrupt mode PMD.**
|
|
|
|
This feature introduces a low-latency one-shot RX interrupt into DPDK. It
|
|
also adds a polling and interrupt mode switch control example.
|
|
|
|
DPDK userspace interrupt notification and handling mechanism is based on
|
|
UIO/VFIO with the following limitations:
|
|
|
|
* Per queue RX interrupt events are only allowed in VFIO which supports
|
|
multiple MSI-X vectors.
|
|
* In UIO, the RX interrupt shares the same vector with other
|
|
interrupts. When the RX interrupt and LSC interrupt are both enabled, only
|
|
the former is available.
|
|
* RX interrupt is only implemented for the linux target.
|
|
* The feature is only currently enabled for tow PMDs: ixgbe and igb.
|
|
|
|
|
|
* **Packet Framework enhancements.**
|
|
|
|
Several enhancements were made to the Packet Framework:
|
|
|
|
* A new configuration file syntax has been introduced for IP pipeline
|
|
applications. Parsing of the configuration file is changed.
|
|
* Implementation of the IP pipeline application is modified to make it more
|
|
structured and user friendly.
|
|
* Implementation of the command line interface (CLI) for each pipeline type
|
|
has been moved to the separate compilation unit. Syntax of pipeline CLI
|
|
commands has been changed.
|
|
* Initialization of IP pipeline is modified to match the new parameters
|
|
structure.
|
|
* New implementation of pass-through pipeline, firewall pipeline, routing
|
|
pipeline, and flow classification has been added.
|
|
* Master pipeline with CLI interface has been added.
|
|
* Added extended documentation of the IP Pipeline.
|
|
|
|
|
|
* **Added API for IEEE1588 timestamping.**
|
|
|
|
This feature adds an ethdev API to enable, disable and read IEEE1588/802.1AS
|
|
PTP timestamps from devices that support it. The following functions were
|
|
added:
|
|
|
|
* ``rte_eth_timesync_enable()``
|
|
* ``rte_eth_timesync_disable()``
|
|
* ``rte_eth_timesync_read_rx_timestamp()``
|
|
* ``rte_eth_timesync_read_tx_timestamp()``
|
|
|
|
The "ieee1588" forwarding mode in testpmd was also refactored to demonstrate
|
|
the new API.
|
|
|
|
|
|
* **Added multicast address filtering.**
|
|
|
|
Added multicast address filtering via a new ethdev function
|
|
``set_mc_addr_list()``.
|
|
|
|
This overcomes a limitation in previous releases where the receipt of
|
|
multicast packets on a given port could only be enabled by invoking the
|
|
``rte_eth_allmulticast_enable()`` function. This method did not work for VFs
|
|
in SR-IOV architectures when the host PF driver does not allow these
|
|
operation on VFs. In such cases, joined multicast addresses had to be added
|
|
individually to the set of multicast addresses that are filtered by the [VF]
|
|
port.
|
|
|
|
|
|
* **Added Flow Director extensions.**
|
|
|
|
Several Flow Director extensions were added such as:
|
|
|
|
* Support for RSS and Flow Director hashes in vector RX.
|
|
* Added Flow Director for L2 payload.
|
|
|
|
|
|
* **Added RSS hash key size query per port.**
|
|
|
|
This feature supports querying the RSS hash key size of each port. A new
|
|
field ``hash_key_size`` has been added in the ``rte_eth_dev_info`` struct
|
|
for storing hash key size in bytes.
|
|
|
|
|
|
* **Added userspace ethtool support.**
|
|
|
|
Added userspace ethtool support to provide a familiar interface for
|
|
applications that manage devices via kernel-space ``ethtool_op`` and
|
|
``net_device_op``.
|
|
|
|
The initial implementation focuses on operations that can be implemented
|
|
through existing ``netdev`` APIs. More operations will be supported in later
|
|
releases.
|
|
|
|
|
|
* **Updated the ixgbe base driver.**
|
|
|
|
The ixgbe base driver was updated with several changes including the
|
|
following:
|
|
|
|
* Added a new 82599 device id.
|
|
* Added new X550 PHY ids.
|
|
* Added SFP+ dual-speed support.
|
|
* Added wait helper for X550 IOSF accesses.
|
|
* Added X550em features.
|
|
* Added X557 PHY LEDs support.
|
|
* Commands for flow director.
|
|
* Issue firmware command when resetting X550em.
|
|
|
|
See the git log for full details of the ixgbe/base changes.
|
|
|
|
|
|
* **Added additional hotplug support.**
|
|
|
|
Port hotplug support was added to the following PMDs:
|
|
|
|
* e1000/igb.
|
|
* ixgbe.
|
|
* i40e.
|
|
* fm10k.
|
|
* ring.
|
|
* bonding.
|
|
* virtio.
|
|
|
|
Port hotplug support was added to BSD.
|
|
|
|
|
|
* **Added ixgbe LRO support.**
|
|
|
|
Added LRO support for x540 and 82599 devices.
|
|
|
|
|
|
* **Added extended statistics for ixgbe.**
|
|
|
|
Implemented ``xstats_get()`` and ``xstats_reset()`` in dev_ops for
|
|
ixgbe to expose detailed error statistics to DPDK applications.
|
|
|
|
These will be implemented for other PMDs in later releases.
|
|
|
|
|
|
* **Added proc_info application.**
|
|
|
|
Created a new ``proc_info`` application, by refactoring the existing
|
|
``dump_cfg`` application, to demonstrate the usage of retrieving statistics,
|
|
and the new extended statistics (see above), for DPDK interfaces.
|
|
|
|
|
|
* **Updated the i40e base driver.**
|
|
|
|
The i40e base driver was updated with several changes including the
|
|
following:
|
|
|
|
* Support for building both PF and VF driver together.
|
|
* Support for CEE DCBX on recent firmware versions.
|
|
* Replacement of ``i40e_debug_read_register()``.
|
|
* Rework of ``i40e_hmc_get_object_va``.
|
|
* Update of shadow RAM read/write functions.
|
|
* Enhancement of polling NVM semaphore.
|
|
* Enhancements on adminq init and sending asq command.
|
|
* Update of get/set LED functions.
|
|
* Addition of AOC phy types to case statement in get_media_type.
|
|
* Support for iSCSI capability.
|
|
* Setting of FLAG_RD when sending driver version to FW.
|
|
|
|
See the git log for full details of the i40e/base changes.
|
|
|
|
|
|
* **Added support for port mirroring in i40e.**
|
|
|
|
Enabled mirror functionality in the i40e driver.
|
|
|
|
|
|
* **Added support for i40e double VLAN, QinQ, stripping and insertion.**
|
|
|
|
Added support to the i40e driver for offloading double VLAN (QinQ) tags to
|
|
the mbuf header, and inserting double vlan tags by hardware to the packets
|
|
to be transmitted. Added a new field ``vlan_tci_outer`` in the ``rte_mbuf``
|
|
struct, and new flags in ``ol_flags`` to support this feature.
|
|
|
|
|
|
|
|
* **Added fm10k promiscuous mode support.**
|
|
|
|
Added support for promiscuous/allmulticast enable and disable in the fm10k PF
|
|
function. VF is not supported yet.
|
|
|
|
|
|
* **Added fm10k jumbo frame support.**
|
|
|
|
Added support for jumbo frame less than 15K in both VF and PF functions in the
|
|
fm10k pmd.
|
|
|
|
|
|
* **Added fm10k mac vlan filtering support.**
|
|
|
|
Added support for the fm10k MAC filter, only available in PF. Updated the
|
|
VLAN filter to add/delete one static entry in the MAC table for each
|
|
combination of VLAN and MAC address.
|
|
|
|
|
|
* **Added support for the Broadcom bnx2x driver.**
|
|
|
|
Added support for the Broadcom NetXtreme II bnx2x driver.
|
|
It is supported only on Linux 64-bit and disabled by default.
|
|
|
|
|
|
* **Added support for the Chelsio CXGBE driver.**
|
|
|
|
Added support for the CXGBE Poll Mode Driver for the Chelsio Terminator 5
|
|
series of 10G/40G adapters.
|
|
|
|
|
|
* **Enhanced support for Mellanox ConnectX-3 driver (mlx4).**
|
|
|
|
* Support Mellanox OFED 3.0.
|
|
* Improved performance for both RX and TX operations.
|
|
* Better link status information.
|
|
* Outer L3/L4 checksum offload support.
|
|
* Inner L3/L4 checksum offload support for VXLAN.
|
|
|
|
|
|
* **Enabled VMXNET3 vlan filtering.**
|
|
|
|
Added support for the VLAN filter functionality of the VMXNET3 interface.
|
|
|
|
|
|
* **Added support for vhost live migration.**
|
|
|
|
Added support to allow live migration of vhost. Without this feature, qemu
|
|
will report the following error: "migrate: Migration disabled: vhost lacks
|
|
VHOST_F_LOG_ALL feature".
|
|
|
|
|
|
* **Added support for pcap jumbo frames.**
|
|
|
|
Extended the PCAP PMD to support jumbo frames for RX and TX.
|
|
|
|
|
|
* **Added support for the TILE-Gx architecture.**
|
|
|
|
Added support for the EZchip TILE-Gx family of SoCs.
|
|
|
|
|
|
* **Added hardware memory transactions/lock elision for x86.**
|
|
|
|
Added the use of hardware memory transactions (HTM) on fast-path for rwlock
|
|
and spinlock (a.k.a. lock elision). The methods are implemented for x86
|
|
using Restricted Transactional Memory instructions (Intel(r) Transactional
|
|
Synchronization Extensions). The implementation fall-backs to the normal
|
|
rwlock if HTM is not available or memory transactions fail. This is not a
|
|
replacement for all rwlock usages since not all critical sections protected
|
|
by locks are friendly to HTM. For example, an attempt to perform a HW I/O
|
|
operation inside a hardware memory transaction always aborts the transaction
|
|
since the CPU is not able to roll-back should the transaction
|
|
fail. Therefore, hardware transactional locks are not advised to be used
|
|
around ``rte_eth_rx_burst()`` and ``rte_eth_tx_burst()`` calls.
|
|
|
|
|
|
* **Updated Jenkins Hash function**
|
|
|
|
Updated the version of the Jenkins Hash (jhash) function used in DPDK from
|
|
the 1996 version to the 2006 version. This gives up to 35% better
|
|
performance, compared to the original one.
|
|
|
|
Note, the hashes generated by the updated version differ from the hashes
|
|
generated by the previous version.
|
|
|
|
|
|
* **Added software implementation of the Toeplitz RSS hash**
|
|
|
|
Added a software implementation of the Toeplitz hash function used by RSS. It
|
|
can be used either for packet distribution on a single queue NIC or for
|
|
simulating RSS computation on a specific NIC (for example after GRE header
|
|
de-encapsulation).
|
|
|
|
|
|
* **Replaced the existing hash library with a Cuckoo hash implementation.**
|
|
|
|
Replaced the existing hash library with another approach, using the Cuckoo
|
|
Hash method to resolve collisions (open addressing). This method pushes
|
|
items from a full bucket when a new entry must be added to it, storing the
|
|
evicted entry in an alternative location, using a secondary hash function.
|
|
|
|
This gives the user the ability to store more entries when a bucket is full,
|
|
in comparison with the previous implementation.
|
|
|
|
The API has not been changed, although new fields have been added in the
|
|
``rte_hash`` structure, which has been changed to internal use only.
|
|
|
|
The main change when creating a new table is that the number of entries per
|
|
bucket is now fixed, so its parameter is ignored now (it is still there to
|
|
maintain the same parameters structure).
|
|
|
|
Also, the maximum burst size in lookup_burst function hash been increased to
|
|
64, to improve performance.
|
|
|
|
|
|
* **Optimized KNI RX burst size computation.**
|
|
|
|
Optimized KNI RX burst size computation by avoiding checking how many
|
|
entries are in ``kni->rx_q`` prior to actually pulling them from the fifo.
|
|
|
|
|
|
* **Added KNI multicast.**
|
|
|
|
Enabled adding multicast addresses to KNI interfaces by adding an empty
|
|
callback for ``set_rx_mode`` (typically used for setting up hardware) so
|
|
that the ioctl succeeds. This is the same thing as the Linux tap interface
|
|
does.
|
|
|
|
|
|
* **Added cmdline polling mode.**
|
|
|
|
Added the ability to process console input in the same thread as packet
|
|
processing by using the ``poll()`` function.
|
|
|
|
* **Added VXLAN Tunnel End point sample application.**
|
|
|
|
Added a Tunnel End point (TEP) sample application that simulates a VXLAN
|
|
Tunnel Endpoint (VTEP) termination in DPDK. It is used to demonstrate the
|
|
offload and filtering capabilities of Intel XL710 10/40 GbE NICsfor VXLAN
|
|
packets.
|
|
|
|
|
|
* **Enabled combining of the ``-m`` and ``--no-huge`` EAL options.**
|
|
|
|
Added option to allow combining of the ``-m`` and ``--no-huge`` EAL command
|
|
line options.
|
|
|
|
This allows user application to run as non-root but with higher memory
|
|
allocations, and removes a constraint on ``--no-huge`` mode being limited to
|
|
64M.
|
|
|
|
|
|
|
|
Resolved Issues
|
|
---------------
|
|
|
|
* **acl: Fix ambiguity between test rules.**
|
|
|
|
Some test rules had equal priority for the same category. That could cause
|
|
an ambiguity in building the trie and test results.
|
|
|
|
|
|
* **acl: Fix invalid rule wildness calculation for bitmask field type.**
|
|
|
|
|
|
* **acl: Fix matching rule.**
|
|
|
|
|
|
* **acl: Fix unneeded trie splitting for subset of rules.**
|
|
|
|
When rebuilding a trie for limited rule-set, don't try to split the rule-set
|
|
even further.
|
|
|
|
|
|
* **app/testpmd: Fix crash when port id out of bound.**
|
|
|
|
Fixed issues in testpmd where using a port greater than 32 would cause a seg
|
|
fault.
|
|
|
|
Fixes: edab33b1c01d ("app/testpmd: support port hotplug")
|
|
|
|
|
|
* **app/testpmd: Fix reply to a multicast ICMP request.**
|
|
|
|
Set the IP source and destination addresses in the IP header of the ICMP
|
|
reply.
|
|
|
|
|
|
* **app/testpmd: fix MAC address in ARP reply.**
|
|
|
|
Fixed issue where in the ``icmpecho`` forwarding mode, ARP replies from
|
|
testpmd contain invalid zero-filled MAC addresses.
|
|
|
|
Fixes: 31db4d38de72 ("net: change arp header struct declaration")
|
|
|
|
|
|
* **app/testpmd: fix default flow control values.**
|
|
|
|
Fixes: 422a20a4e62d ("app/testpmd: fix uninitialized flow control variables")
|
|
|
|
|
|
* **bonding: Fix crash when stopping inactive slave.**
|
|
|
|
|
|
* **bonding: Fix device initialization error handling.**
|
|
|
|
|
|
* **bonding: Fix initial link status of slave.**
|
|
|
|
On Fortville NIC, link status change interrupt callback was not executed
|
|
when slave in bonding was (re-)started.
|
|
|
|
|
|
* **bonding: Fix socket id for LACP slave.**
|
|
|
|
Fixes: 46fb43683679 ("bond: add mode 4")
|
|
|
|
|
|
* **bonding: Fix device initialization error handling.**
|
|
|
|
|
|
* **cmdline: Fix small memory leak.**
|
|
|
|
A function in ``cmdline.c`` had a return that did not free the buf properly.
|
|
|
|
|
|
* **config: Enable same drivers options for Linux and BSD.**
|
|
|
|
Enabled vector ixgbe and i40e bulk alloc for BSD as it is already done for
|
|
Linux.
|
|
|
|
Fixes: 304caba12643 ("config: fix bsd options")
|
|
Fixes: 0ff3324da2eb ("ixgbe: rework vector pmd following mbuf changes")
|
|
|
|
|
|
* **devargs: Fix crash on failure.**
|
|
|
|
This problem occurred when passing an invalid PCI id to the blacklist API in
|
|
devargs.
|
|
|
|
|
|
* **e1000/i40e: Fix descriptor done flag with odd address.**
|
|
|
|
|
|
* **e1000/igb: fix ieee1588 timestamping initialization.**
|
|
|
|
Fixed issue with e1000 ieee1588 timestamp initialization. On initialization
|
|
the IEEE1588 functions read the system time to set their timestamp. However,
|
|
on some 1G NICs, for example, i350, system time is disabled by default and
|
|
the IEEE1588 timestamp was always 0.
|
|
|
|
|
|
* **eal/bsd: Fix inappropriate header guards.**
|
|
|
|
|
|
* **eal/bsd: Fix virtio on FreeBSD.**
|
|
|
|
Closing the ``/dev/io`` fd caused a SIGBUS in inb/outb instructions as the
|
|
process lost the IOPL privileges once the fd is closed.
|
|
|
|
Fixes: 8a312224bcde ("eal/bsd: fix fd leak")
|
|
|
|
|
|
* **eal/linux: Fix comments on vfio MSI.**
|
|
|
|
|
|
* **eal/linux: Fix irq handling with igb_uio.**
|
|
|
|
Fixed an issue where the introduction of ``uio_pci_generic`` broke
|
|
interrupt handling with igb_uio.
|
|
|
|
Fixes: c112df6875a5 ("eal/linux: toggle interrupt for uio_pci_generic")
|
|
|
|
|
|
* **eal/linux: Fix numa node detection.**
|
|
|
|
|
|
* **eal/linux: Fix socket value for undetermined numa node.**
|
|
|
|
Sets zero as the default value of pci device numa_node if the socket could
|
|
not be determined. This provides the same default value as FreeBSD which has
|
|
no NUMA support, and makes the return value of ``rte_eth_dev_socket_id()``
|
|
be consistent with the API description.
|
|
|
|
|
|
* **eal/ppc: Fix cpu cycle count for little endian.**
|
|
|
|
On IBM POWER8 PPC64 little endian architecture, the definition of tsc union
|
|
will be different. This fix enables the right output from ``rte_rdtsc()``.
|
|
|
|
|
|
* **ethdev: Fix check of threshold for TX freeing.**
|
|
|
|
Fixed issue where the parameter to ``tx_free_thresh`` was not consistent
|
|
between the drivers.
|
|
|
|
|
|
* **ethdev: Fix crash if malloc of user callback fails.**
|
|
|
|
If ``rte_zmalloc()`` failed in ``rte_eth_dev_callback_register`` then the
|
|
NULL pointer would be dereferenced.
|
|
|
|
|
|
* **ethdev: Fix illegal port access.**
|
|
|
|
To obtain a detachable flag, ``pci_drv`` is accessed in
|
|
``rte_eth_dev_is_detachable()``. However ``pci_drv`` is only valid if port

|
|
|
|
The function to clear the TX ring when a port was being closed, e.g. on exit
|
|
in testpmd, was not checking the mbuf refcnt before freeing it. Since the
|
|
function in the vector driver to clear the ring after TX does not setting

the pointer to NULL post-free, this caused crashes if mbuf debugging was

|
turned on.

|
|
|
Added a new ``priv_size`` field in mbuf structure that should be initialized
|
|
at mbuf pool creation. This field contains the size of the application
|
|
private data in mbufs.
|
|
|
|
Introduced new static inline functions ``rte_mbuf_from_indirect()`` and
|
|
``rte_mbuf_to_baddr()`` to replace the existing macros, which take the
|
|
private size into account when attaching and detaching mbufs.
|
|
|
|
|
|
* **mbuf: Fix data room size calculation in pool init.**
|
|
|
|
Deduct the mbuf data room size from ``mempool->elt_size`` and ``priv_size``,
|
|
instead of using an hardcoded value that is not related to the real buffer
|
|
size.
|
|
|
|
To use ``rte_pktmbuf_pool_init()``, the user can either:
|
|
|
|
* Give a NULL parameter to rte_pktmbuf_pool_init(): in this case, the
|
|
private size is assumed to be 0, and the room size is ``mp->elt_size`` -
|
|
``sizeof(struct rte_mbuf)``.
|
|
* Give the ``rte_pktmbuf_pool_private`` filled with appropriate
|
|
data_room_size and priv_size values.
|
|
|
|
|
|
* **mbuf: Fix init when private size is not zero.**
|
|
|
|
Allow the user to use the default ``rte_pktmbuf_init()`` function even if
|
|
the mbuf private size is not 0.
|
|
|
|
|
|
* **mempool: Add structure for object headers.**
|
|
|
|
Each object stored in mempools are prefixed by a header, allowing for
|
|
instance to retrieve the mempool pointer from the object. When debug is
|
|
enabled, a cookie is also added in this header that helps to detect
|
|
corruptions and double-frees.
|
|
|
|
Introduced a structure that materializes the content of this header,
|
|
and will simplify future patches adding things in this header.

|
|
|
|
Negotiate the virtio ring size. The host may allow for very large rings but
|
|
application may only want a smaller ring. Conversely, if the number of
|
|
descriptors requested exceeds the virtio host queue size, then just silently
|
|
use the smaller host size.
|
|
|
|
This fixes issues with virtio in non-QEMU environments. For example Google
|
|
Compute Engine allows up to 16K elements in ring.

Known Issues
|
|
------------
|
|
|
|
* When running the ``vmdq`` sample or ``vhost`` sample applications with the
|
|
Intel(R) XL710 (i40e) NIC, the configuration option
|
|
``CONFIG_RTE_MAX_QUEUES_PER_PORT`` should be increased from 256 to 1024.
|
|
|
|
|
|
* VM power manager may not work on systems with more than 64 cores.
|
|
|
|
|
|
API Changes
|
|
-----------
|
|
|
|
* The order that user supplied RX and TX callbacks are called in has been
|
|
changed to the order that they were added (fifo) in line with end-user
|
|
expectations. The previous calling order was the reverse of this (lifo) and
|
|
was counter intuitive for users. The actual API is unchanged.
|
|
|
|
|
|
ABI Changes
|
|
-----------
|
|
|
|
* The ``rte_hash`` structure has been changed to internal use only.
