net/mlx: version rdma-core glue libraries When built as separate objects, these libraries do not have unique names. Since they do not maintain a stable ABI, loading an incompatible library may result in a crash (e.g. in case multiple versions are installed). This patch addresses the above by versioning glue libraries, both on the file system (version suffix) and by comparing a dedicated version field member in glue structures.

net/mlx5: accelerate DV flow counter transactions The DevX interface exposes a new feature to the PMD that can allocate a batch of counters by one FW command. It can improve the flow transaction rate (with count action). Add a new counter pools mechanism to manage HW counters in the PMD. So, for each flow with counter creation the PMD will try to find a free counter in the PMD pools container and only if there is no a free counter, it will allocate a new DevX batch counters. Currently we cannot support batch counter for a group 0 flow, so create a 2 container types, one which allocates counters one by one and one which allocates X counters by the batch feature. The allocated counters objects are never released back to the HW assuming the flows maximum number will be close to the actual value of the flows number. Later, it can be updated, and dynamic release mechanism can be added. The counters are contained in pools, each pool with 512 counters. The pools are contained in counter containers according to the allocation resolution type - single or batch. The cache memory of the counters statistics is saved as raw data per pool. All the raw data memory is allocated for all the container in one memory allocation and is managed by counter_stats_mem_mng structure which registers all the raw memory to the HW. Each pool points to one raw data structure. The query operation is in pool resolution which updates all the pool counter raw data by one operation.

net/mlx: update C compliance standard This commit addresses a compilation issue against Glibc >= 2.25, which implements assert() through a nonstandard ({ }) construct. Such constructs can normally not be used without __extension__ keyword when -pedantic is enabled, as is the case when compiling mlx4 and mlx5 PMDs in debug mode. While assert.h checks for the compiler ability to support GNU extensions, Clang, unlike GCC, does not allow the above syntax when combining -std=gnu99 with -pedantic. Work around missing keyword by moving these PMDs to a stricter compliance standard without GNU extensions but properly checked by Glibc. Doing so is supported on the DPDK side since includes have been cleaned up. Even in C11, using types other than _Bool or signed/unsigned int for bit-fields is an extension. Some GCC versions complain about that when -pedantic checks are enabled. The RTE_STD_C11 macro correctly prevented this issue with C99 but not with C11 as it becomes a no-op. Forcing the extension keyword addresses it. Signed-off-by: Adrien Mazarguil <adrien.mazarguil@6wind.com> Tested-by: Yongseok Koh <yskoh@mellanox.com>

net/mlx5: spawn rdma-core dependency plug-in When mlx5 is not compiled directly as an independent shared object (e.g. CONFIG_RTE_BUILD_SHARED_LIB not enabled for performance reasons), DPDK applications inherit its dependencies on libibverbs and libmlx5 through rte.app.mk. This is an issue both when DPDK is delivered as a binary package (Linux distributions) and for end users because rdma-core then propagates as a mandatory dependency for everything.

The number of consumed strides in CQE is accumulated to keep track of the current stride index. However, it is safer to directly use stride index in CQE to avoid out-of-order situation which can possibly be caused by introducing LRO in the future. If Rx CQE compression is enabled, HW can be configured to store the stride index in a mini-CQE but this will need newer version of library/driver. Therefore, since this change, MPRQ is only supported with the newer library/driver and Rx hash result is not supported if MPRQ is enabled along with Rx CQE compression.

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 by default.

net/mlx5: accelerate DV flow counter query All the DV counters are cashed in the PMD memory and are contained in pools which are contained in containers according to the counters allocation type - batch or single. Currently, the flow counter query is done synchronously in pool resolution means that on the user request a FW command is triggered to read all the counters in the pool. A new feature of devX to asynchronously read batch of flow counters allows to accelerate the user query operation. Using the DPDK host thread, the PMD periodically triggers asynchronous query in pool resolution for all the counter pools and an interrupt is triggered by the FW when the values are updated. In the interrupt handler the pool counter values raw data is replaced using a double buffer algorithm (very fast). In the user query, the PMD just returns the last query values from the PMD cache - no system-calls and FW commands are triggered from the user control thread on query operation! More synchronization is added with the host thread: Container resize uses double buffer algorithm. Pools growing in container uses atomic operation. Pool query buffer replace uses a spinlock. Pool minimum devX counter ID uses atomic operation. Signed-off-by: Matan Azrad <matan@mellanox.com> Acked-by: Shahaf Shuler <shahafs@mellanox.com>

net/mlx5: fix build with rdma-core v19 The flow counter support introduced by commit 9a761de8ea14 ("net/mlx5: flow counter support") was intend to work only with MLNX_OFED_4.3 as the upstream rdma-core libraries were lack such support. On rdma-core v19 the support for the flow counters was added but with different user APIs, hence causing compilation issues on the PMD. This patch fix the compilation errors by forcing the flow counters to be enabled only with MLNX_OFED APIs. Once MLNX_OFED and rdma-core APIs will be aligned, a proper patch to support the new API will be submitted.

net/mlx5: add port representor awareness The current PCI probing method is not aware of Verbs port representors, which appear as standard Verbs devices bound to the same PCI address and cannot be distinguished. Problem is that more often than not, the wrong Verbs device is used, resulting in unexpected traffic. This patch makes the driver discard representors to only use the master device. If unable to identify it (e.g. kernel drivers not recent enough), either: - There is only one matching device which isn't identified as a representor, in that case use it. - Otherwise log an error and do not probe the device.

The new Linux kernels starting from 5.0 provide the port name for master device and the implemented representor recognizing method does not work. The new recognizing method is based on querying the VF number, has been created on the base of the device. The IFLA_NUM_VF attribute is returned by kernel if IFLA_EXT_MASK attribute is specified in the Netlink request message. Also the presence check of device symlink in device sysfs folder is added to distinguish representors with sysfs based method.

This is an issue both when DPDK is delivered as a binary package (Linux distributions) and for end users because rdma-core then propagates as a mandatory dependency for everything. Application writers relying on binary DPDK packages are not necessarily aware of this fact and may end up delivering packages with broken dependencies. This patch therefore introduces an intermediate internal plug-in hard-linked with rdma-core (to preserve symbol versioning) loaded by the PMD through dlopen(), so that a missing rdma-core does not cause unresolved symbols, allowing applications to start normally.
