2018-02-05plugins: odp: Remove copying from the esp_{encrypt, decrypt}Szymon Sliwa2-195/+189
Change-Id: I5d71505e221e837c7569963fda674e970e5ee31d Signed-off-by: Szymon Sliwa <szs@semihalf.com>
2018-02-05plugins: odp: Add ODP-IPsec nodeSzymon Sliwa7-0/+1535
Based heavily on the src/vnet/ipsec. Reuses the pure software VPP IPsec implementation CLI command. To use enable-odp-crypto needs to be present in the odp section of startup configuration, like this: odp { enable-odp-crypto } Currenlty only IPv4 is supported, and only in transport mode. Authentication headers are not supported, this limitation is inherited from VPP. Supported crypto algorithms are aes-cbc-128 for encryption, and sha-512-256, sha-256-128, sha1-96 for authentication Change-Id: I08c66f96a73d8cb4ef1095f181ddf47506abc39a Signed-off-by: Szymon Sliwa <szs@semihalf.com>
2018-02-01plugins: odp: Fix minor bugsMichal Mazur2-5/+8
1) Remove function vlib_buffer_set_known_state because it is not multi-thread safe. 2) Stop all worker threads before deleting interfaces. 3) Fix style of odp_packet_exit function. 4) Fix infinite loop in odp_config.

2018-01-17plugins: odp: Get address range from pool infoMichal Mazur1-3/+6
Adjust ODP plugin for Caterpillar release. Address range of packet pool can be obtained using odp_pool_info API. Change-Id: I0b0175cce4d9e44ca27709d1dbca560a4a72b5a1 Signed-off-by: Michal Mazur <mkm@semihalf.com>
2018-01-17plugins: odp: Add support for buffer recyclingMichal Mazur2-13/+54
Buffers with VLIB_BUFFER_RECYCLE flag set should not be freed. They are replicated on send and sent back to vlib for processing. Change-Id: If381884fa7c898253f35dc3a39feeb4eb1529286 Signed-off-by: Michal Mazur <mkm@semihalf.com>
2018-01-11plugins: odp: Add support for free list of buffersMichal Mazur2-36/+275
Free lists are required by some VPP nodes e.g. IPv6. Update copyrigths as lots of code were imported from src/vlib/buffer.c Change-Id: Ie4c56d3a3104624fe77a04069fe3ba1281d3f0cb Signed-off-by: Michal Mazur <mkm@semihalf.com>
2018-01-11plugins: odp: Fix error when all interfaces removedMichal Mazur1-7/+20
Packet pool cannot be destroyed when last interface is deleted because it will not be reallocated on creation of a new interface. Change-Id: Iec7b03b4413fc6602a7a1493ffd706f4c4dd1309 Signed-off-by: Michal Mazur <mkm@semihalf.com>
2018-01-08plugins: odp: Remove 'platform-params' optionMichal Mazur1-35/+2
ODP platform can now be configured using environment variable ODP_PLATFORM_PARAMS. Remove the option from startup config file. Change-Id: I9d550dabd32c691a031bb88d5453c8146d5fbce8 Signed-off-by: Michal Mazur <mkm@semihalf.com>
2017-12-27Fix and improve Rx Scheduler modeMichal Mazur3-39/+71
Fix support of atomic mode and add two new modes: parallel and ordered. Three modes of synchronization between threads are supported now: - parallel - no synchronization between events - ordered - relative sequence of events is restored in output queues - atomic - only a single thread may process events from a single queue Change-Id: I9399aa601f0927042ac0f7f1e5f265f4d47724b8 Signed-off-by: Michal Mazur <mkm@semihalf.com>
2017-12-18More optimizations for Tx and Rx loopsMichal Mazur5-167/+195
1) Parse multiple output packets in loop. 2) Remove checking for error flags, they are never set because ODP parser is disabled. 3) Do not call vlib_buffer_advance if not necessary. 4) Remove lock in TX path. Queues are synchronized by ODP. 5) Optimize detection of packet type. 6) Create a wrapper for call to odp_packet_user_area.

2017-12-14Read ODP configuration from VPP startup configMichal Mazur5-80/+310
1) Allow to setup size of allocated memory, number of packets in the pool, number of packets in transmit burst and delay in scheduler mode from VPP startup file. More details are in template: src/vpp/conf/startup.conf 2) Separate Rx mode from Tx mode. Traffic Manager is not supported. 3) Devices defined in VPP startup are automatically created at start.

2017-12-14Add support for multiple Rx and Tx queuesMichal Mazur5-69/+150
1) Incoming packets can be spread across multiple worker threads based on IP and TCP/UDP headers. 2) Multiple output queues are used in Burst mode if supported by hardware (checked in interface capabilities) 3) Synchronization of output traffic can be disabled due to multiple Tx queues - one for each thread.

2017-12-14Optimize Rx and Tx pathsMichal Mazur3-43/+199
1) Handle multiple ODP packets at once in receive loop 2) Wait to collect as many RX buffers as possible in single vector 3) Add prefetch of received and transmitted buffers 4) Disable parser, classifier and synchronization of RX queues Synchronization of Tx queues can also be disabled if 2 ports used.

2017-12-14Create worker threads using ODP API (direct in/out mode)Michal Mazur4-54/+103
This patch allows VPP to run multiple worker threads compatible with ODP. By default a single thread is assigned to each interface but this can be changed using "set interface rx-placement" command. Only Direct input/output mode without RSS is supported. Change-Id: Ia6af7e5af4950159eb28b7d56bc9c8d34b80f8d4 Signed-off-by: Michal Mazur <mkm@semihalf.com>
2017-12-14Move odp_packet_main structure to shared memory.Michal Mazur5-18/+32
This structure contains data shared among multiple threads and must be globally accessible. Change-Id: Ibde8222e9ed3f61561f7902750a1716da5c0bd81 Signed-off-by: Michal Mazur <mkm@semihalf.com>
