6 years agoring/c11: relax ordering for load and store of the head

ring/c11: relax ordering for load and store of the head

When calling __atomic_compare_exchange_n, use relaxed ordering for the
success case, as multiple producers/consumers do not release updates to
each other so no need for acquire or release ordering.

Because the thread fence in place, ordering for the first iteration can
be relaxed.

Run the ring perf test on the following testbed:

6 years agoring/c11: keep deterministic order allowing retry to work
Gavin Hu [Fri, 9 Nov 2018 11:42:46 +0000 (19:42 +0800)]
ring/c11: keep deterministic order allowing retry to work

Use case scenario:
1) Thread 1 is enqueuing. It reads prod.head and gets stalled for some
   reasons (running out of cpu time, preempted,...)
2) Thread 2 is enqueuing. It succeeds in enqueuing and moves prod.head
   forward.
3) Thread 3 is dequeuing. It succeeds in dequeuing and moves the cons.tail
   beyond the prod.head read by thread 1.
4) Thread 1 is re-scheduled. It reads cons.tail.

cpu1(producer)      cpu2(producer)          cpu3(consumer)
load r->prod.head
    ^               load r->prod.head
    |               load r->cons.tail
    |               store r->prod.head(+n)
  stalled           <-- enqueue ----->
    |               store r->prod.tail(+n)
    |                                        load r->cons.head
    |                                        load r->prod.tail
    |                                        store r->cons.head(+n)
    |                                        <...dequeue.....>
    v                                        store r->cons.tail(+n)
load r->cons.tail

For thread 1, the __atomic_compare_exchange_n detects the outdated
prod.head and retry the flow with the new one. This retry flow works ok on
strong ordering platform(eg:x86). But for weak ordering platforms(arm,
ppc), loading cons.tail and prod.head might be re-ordered, prod.head is new
but cons.tail becomes too old, the retry flow, based on the detection of
outdated head, does not trigger as expected, thus the outdate cons.tail
causes wrong free_entries.

Similarly, for dequeuing, outdated prod.tail leads to wrong avail_entries.

The fix is to keep the deterministic order of two loads allowing the retry
to work.

Run the ring perf test on the following testbed:
HW: ThunderX2 B0 CPU CN9975 v2.0, 2 sockets, 28core, 4 threads/core, 2.5GHz

ethdev: remove experimental tag for iterator API

After removing the function rte_eth_dev_attach(),
there are two replacement solutions possible:
one using probe event notification, and one using a new iterator.
So the application can get the new probed ports either asynchronously
or synchronously.

The iterator API is new in DPDK 18.11 so they got the experimental
tag by policy. It causes an issue for strict applications which do
not use experimental functions, and want to use the synchronous method.

The replacement for removed API should not be experimental.

net/mlx5: add E-Switch VXLAN to validation routine

This patch adds VXLAN support for flow item/action lists validation.
The following entities are now supported:

- RTE_FLOW_ITEM_TYPE_VXLAN, contains the tunnel VNI

- RTE_FLOW_ACTION_TYPE_VXLAN_DECAP, if this action is specified
  the items in the flow items list treated as outer  network
  parameters for tunnel outer header match. The ethernet layer
  addresses always are treated as inner ones.

- RTE_FLOW_ACTION_TYPE_VXLAN_ENCAP, contains the item list to
  build the encapsulation header. In current implementation the
  values is the subject for some constraints:
    - outer source MAC address will be always unconditionally
      set to the one of MAC addresses of outer egress interface
    - no way to specify source UDP port
    - all abovementioned parameters are ignored if specified
      in the rule, warning messages are sent to the log

Minimal tunneling support is also added. If VXLAN decapsulation
action is specified the ETH item can follow the VXLAN VNI item,
the content of this ETH item is treated as inner MAC addresses
and type. The outer ETH item for VXLAN decapsulation action
is always ignored.

net/mlx5: add 128B padding of Rx completion entry

A PMD parameter (rxq_cqe_pad_en) is added to enable 128B padding of CQE on
RX side. The size of CQE is aligned with the size of a cacheline of the
core. If cacheline size is 128B, the CQE size is configured to be 128B even
though the device writes only 64B data on the cacheline. This is to avoid
unnecessary cache invalidation by device's two consecutive writes on to one
cacheline. However in some architecture, it is more beneficial to update
entire cacheline with padding the rest 64B rather than striding because
read-modify-write could drop performance a lot. On the other hand, writing
extra data will consume more PCIe bandwidth and could also drop the maximum
throughput. It is recommended to empirically set this parameter. Disabled

ring/c11: synchronize load and store of the tail

Synchronize the load-acquire of the tail and the store-release
within update_tail, the store release ensures all the ring operations,
enqueue or dequeue, are seen by the observers on the other side as soon
as they see the updated tail. The load-acquire is needed here as the
data dependency is not a reliable way for ordering as the compiler might
break it by saving to temporary values to boost performance.
When computing the free_entries and avail_entries, use atomic semantics
to load the heads and tails instead.

The patch was benchmarked with test/ring_perf_autotest and it decreases
the enqueue/dequeue latency by 5% ~ 27.6% with two lcores, the real gains
are dependent on the number of lcores, depth of the ring, SPSC or MPMC.
For 1 lcore, it also improves a little, about 3 ~ 4%.
It is a big improvement, in case of MPMC, with two lcores and ring size
of 32, it saves latency up to (3.26-2.36)/3.26 = 27.6%.

This patch is a bug fix, while the improvement is a bonus. In our analysis
the improvement comes from the cacheline pre-filling after hoisting load-
acquire from _atomic_compare_exchange_n up above.

The test command:
$sudo ./test/test/test -l 16-19,44-47,72-75,100-103 -n 4 --socket-mem=\
