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.
That's why the experimental status of the ethdev iterator is removed.

eal: remove experimental tag for probe/remove

The functions rte_dev_probe() and rte_dev_remove() are new
in DPDK 18.11 so they got the experimental tag by policy.
However they are too much basic functions for being skipped
by strict applications which do not use experimental functions.

The alternative is to use rte_eal_hotplug_add() and
rte_eal_hotplug_remove(), but their API requires the application
to parse the devargs string in order to provide bus name,
device name and driver arguments.

The new function rte_dev_probe() is really simpler to use and
more flexible by accepting any devargs string.

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=\

6 years agotest/crypto: remove redundant RSA verification

test/crypto: remove redundant RSA verification

Change unit test app to check only for op->status =
RTE_CRYPTO_OP_STATUS_SUCCESS/ERROR instead of calling rsa_verify().
as the cryptodev API is expected to return error incase of data
mismatch.

6 years agocrypto/openssl: fix RSA verify operation
Akash Saxena [Thu, 25 Oct 2018 10:00:56 +0000 (10:00 +0000)]
crypto/openssl: fix RSA verify operation

In lib cryptodev, RSA verify operation inputs plain message text and
corresponding signature and expected to return
RTE_CRYPTO_OP_STATUS_SUCCESS/FAILURE on a signature match/mismatch.
Current OpenSSL PMD RSA verify implementation overrides application passed
sign input by decrypted output which isn't expected.

This patch addresses this issue in OpenSSL PMD. Now, OpenSSL PMD use
tmp buffer to pass to OpenSSL sign API and memcmp output with
original plain text to verify signature match.
Set op->status = RTE_CRYPTO_OP_STATUS_ERROR on signature mismatch.
