Cristian Dumitrescu [Mon, 12 Jun 2017 13:35:38 +0000 (14:35 +0100)]
ethdev: add traffic management ops get API

The rte_flow feature breaks the monolithic approach for ethdev by
introducing the new rte_flow API to ethdev using a plugin-like approach.

Basically, the rte_flow API is still logically part of ethdev:
- It extends the ethdev functionality: rte_flow is a new feature/
  capability of ethdev;
- all its functions work on an Ethernet device: the first parameter of the
  rte_flow functions is Ethernet device port ID.

Also, the rte_flow API is a sort of capability plugin for ethdev:
- the rte_flow API functions have their own name space: they are called
  rte_flow_operationXYZ() as opposed to rte_eth_dev_flow_operationXYZ());
- the rte_flow API functions are placed in separate files in the same
  librte_ether folder as opposed to rte_ethdev.[hc].

The way it works is by using the existing ethdev API function
rte_eth_dev_filter_ctrl() to query the current Ethernet device port ID for
the support of the rte_flow capability and return the pointer to the
rte_flow operations when supported and NULL otherwise:

struct rte_flow_ops *eth_flow_ops;
int rte = rte_eth_dev_filter_ctrl(eth_port_id,
RTE_ETH_FILTER_GENERIC, RTE_ETH_FILTER_GET, &eth_flow_ops);

This patch reuses the same approach for ethdev Traffic Management API.

Jiayu Hu [Sun, 9 Jul 2017 05:46:45 +0000 (13:46 +0800)]
lib/gro: support TCP/IPv4

In this patch, we introduce five APIs to support TCP/IPv4 GRO.
- gro_tcp4_reassemble: reassemble an inputted TCP/IPv4 packet.
- gro_tcp4_tbl_create: create a TCP/IPv4 reassembly table, which is used
    to merge packets.
- gro_tcp4_tbl_destroy: free memory space of a TCP/IPv4 reassembly table.
- gro_tcp4_tbl_pkt_count: return the number of packets in a TCP/IPv4
    reassembly table.
- gro_tcp4_tbl_timeout_flush: flush timeout packets from a TCP/IPv4
    reassembly table.

TCP/IPv4 GRO API assumes all inputted packets are with correct IPv4
and TCP checksums. And TCP/IPv4 GRO API doesn't update IPv4 and TCP
checksums for merged packets. If inputted packets are IP fragmented,
TCP/IPv4 GRO API assumes they are complete packets (i.e. with L4
headers).

In TCP/IPv4 GRO, we use a table structure, called TCP/IPv4 reassembly
table, to reassemble packets. A TCP/IPv4 reassembly table includes a key
array and a item array, where the key array keeps the criteria to merge
packets and the item array keeps packet information.

One key in the key array points to an item group, which consists of
packets which have the same criteria value. If two packets are able to
merge, they must be in the same item group. Each key in the key array
includes two parts:
- criteria: the criteria of merging packets. If two packets can be
    merged, they must have the same criteria value.
- start_index: the index of the first incoming packet of the item group.

Each element in the item array keeps the information of one packet. It
mainly includes three parts:
- firstseg: the address of the first segment of the packet
- lastseg: the address of the last segment of the packet
- next_pkt_index: the index of the next packet in the same item group.
    All packets in the same item group are chained by next_pkt_index.
    With next_pkt_index, we can locate all packets in the same item
    group one by one.

To process an incoming packet needs three steps:
a. check if the packet should be processed. Packets with one of the
    following properties won't be processed:
- FIN, SYN, RST, URG, PSH, ECE or CWR bit is set;
- packet payload length is 0.
b. traverse the key array to find a key which has the same criteria
    value with the incoming packet. If find, goto step c. Otherwise,
    insert a new key and insert the packet into the item array.
c. locate the first packet in the item group via the start_index in the
    key. Then traverse all packets in the item group via next_pkt_index.
    If find one packet which can merge with the incoming one, merge them
    together. If can't find, insert the packet into this item group.

Jiayu Hu [Sun, 9 Jul 2017 05:46:44 +0000 (13:46 +0800)]
lib/gro: add Generic Receive Offload API framework

Generic Receive Offload (GRO) is a widely used SW-based offloading
technique to reduce per-packet processing overhead. It gains
performance by reassembling small packets into large ones. This
patchset is to support GRO in DPDK. To support GRO, this patch
implements a GRO API framework.

To enable more flexibility to applications, DPDK GRO is implemented as
a user library. Applications explicitly use the GRO library to merge
small packets into large ones. DPDK GRO provides two reassembly modes.
One is called lightweight mode, the other is called heavyweight mode.
If applications want to merge packets in a simple way and the number
of packets is relatively small, they can use the lightweight mode.
If applications need more fine-grained controls, they can choose the
heavyweight mode.

rte_gro_reassemble_burst is the main reassembly API which is used in
lightweight mode and processes N packets at a time. For applications,
performing GRO in lightweight mode is simple. They just need to invoke
rte_gro_reassemble_burst. Applications can get GROed packets as soon as
rte_gro_reassemble_burst returns.

rte_gro_reassemble is the main reassembly API which is used in
heavyweight mode and tries to merge N inputted packets with the packets
in GRO reassembly tables. For applications, performing GRO in heavyweight
mode is relatively complicated. Before performing GRO, applications need
to create a GRO context object, which keeps reassembly tables of
desired GRO types, by rte_gro_ctx_create. Then applications can use
rte_gro_reassemble to merge packets. The GROed packets are in the
reassembly tables of the GRO context object. If applications want to get
them, applications need to manually flush them by flush API.

app/testeventdev: add perf all types queue test

This is a performance test case that aims at testing the following:
1. Measure the number of events can be processed in a second.
2. Measure the latency to forward an event.

The atq queue test functions as same as "perf_queue" test.
The difference is, it uses, "all type queue" scheme instead of separate
queues for each stage and thus reduces the number of queues required to
realize the use case and enables flow pinning as the event does not
move to the next queue.

Example command to run perf "all types queue" test:

sudo build/app/dpdk-test-eventdev --vdev=event_octeontx --\
--test=perf_atq --plcores=2 --wlcore=3 --stlist=p --nb_pkts=1000000000

1. Measure the number of events can be processed in a second.
2. Measure the latency to forward an event.

The perf queue test configures the eventdev with Q queues and P ports,
where Q is nb_producers * nb_stages and P is nb_workers + nb_producers.

The user can choose the number of workers, the number of producers and
number of stages through the --wlcores , --plcores and the --stlist
application command line arguments respectively.

The producer(s) injects the events to eventdev based the
first stage sched type list requested by the user through --stlist
the command line argument.

Based on the number of stages to process(selected through --stlist),
the application forwards the event to next upstream queue and
terminates when it reaches the last stage in the pipeline.
On event termination, application increments the number events
processed and print periodically in one second to get the
number of events processed in one second.

When --fwd_latency command line option selected, the application
inserts the timestamp in the event on the first stage and then
on termination, it updates the number of cycles to forward
a packet. The application uses this value to compute the average
latency to a forward packet.

Example command to run perf queue test:
sudo build/app/dpdk-test-eventdev --vdev=event_sw0 -- --test=perf_queue\
--slcore=1 --plcores=2 --wlcore=3 --stlist=p --nb_pkts=1000000000

app/testeventdev: add order queue test

The order queue test configures the eventdev with two queues
and an event producer to inject the events to q0(ordered) queue.
Both q0(ordered) and q1(atomic) are linked to all the workers.

The event producer maintains a sequence number per flow and
injects the events to the ordered queue.

The worker receives the events from ordered queue and
forwards to atomic queue. Since the events from an ordered queue can
be processed in parallel on the different workers, the
ingress order of events might have changed on the downsteam
atomic queue enqueue. On enqueue to the atomic queue, the eventdev PMD
driver reorders the event to the original ingress order
i.e producer ingress order).

When the event is dequeued from the atomic queue by the worker,
this test verifies the expected
sequence number of associated event per flow by comparing
the free running expected sequence number per flow.

sudo build/app/dpdk-test-eventdev --vdev=event_sw0 --\
