2019-03-06PROX generator: performance optimization (2/4)Xavier Simonart1-22/+20
Improve PROX generator performance by pre-calculating bytes_to_tsc. This improvement is only implemented for non-pcap generator, where only few different packet sizes are usually generated. This change might have a negative performance impact in some cases, if many different packet sizes are generated, resulting in higher memory usage. This is the case for instance if random is applied to packet size. In addition, simplified the rx path, receiving now only MAX_PKT_BURST packets per handle loop. Before we were trying to empty the NIC looping on RX packets, ending up with many rx packets per handle loop. This was used to determine an lower bound for the time the packet was received. We now set the lower bound when less than MAX_PKT_BURST has been received. Change-Id: I1ce813d7e4ac1577ea412c590add5d6f94b36ec7 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2019-02-20Use link speed from device capability instead of negotiated speedaXavier Simonart1-10/+61
JIRA: SAMPLEVNF-151 link speed is used in gen and lat latency extrapolations. Using a link_speed value lower than the actual link speed might result in errors (e.g. negative latencies). Negotiated link speed might be reported slowly (as reported through irq) Hence it is better to use the device capability link speed. In addition, this remove the check for link speed changes in fastpath. Change-Id: I0f475fe5e139b046012de6cd0b710e4390735078 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2019-01-23Configure RSS hashing to IP/UDP and check for with PMD supportXavier Simonart1-2/+9
RSS was enabled when rss=yes is set in the configuration or when multiqueue is being used. But when RSS was enabled the types of packets on which RSS hashing was applied might not be supported by the PMD, as almost every PMD supported a different set of packets.

2018-12-06Merge "Fix potential crash when getting device info"Deepak S1-10/+12
2018-12-05Add support for VLAN insert and strippingXavier Simonart1-0/+2
JIRA: SAMPLEVNF-149 VLAN can be enabled on a port by adding "vlan=yes" in the port section. When VLAN is enabled on a port, then DEV_RX_OFFLOAD_VLAN_STRIP and DEV_TX_OFFLOAD_VLAN_INSERT are enabled (if device supports it). This will cause VLAN to be stripped from any packets received with the proper tag, and VLAN to be added for any packets being transmitted. The VLAN ID themselves are configured through the physical function using something like (where ens801f1 isthe PF): ip link set ens801f1 vf 0 vlan 1111 Change-Id: I945c87b0c18565da479ecaa08e5ffce91232a7ce Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>

2018-09-04Workaround DPDK net/virtio queue setup issuePatrice Buriez1-14/+14
JIRA: SAMPLEVNF-127 PROX was crashing in the VM with vector mode enabled and multiple OVS queues. This was not really a PROX bug, but a DPDK issue, which has been fixed by DPDK commit https://git.dpdk.org/dpdk/commit/?id=efc83a1e7fc3 This "net/virtio: fix queue setup consistency" is included in DPDK 17.11 and subsequent versions, and has been backported into: - DPDK 16.11.4: https://git.dpdk.org/dpdk-stable/commit/?h=16.11&id=516447a5056c - DPDK 17.08.1: https://git.dpdk.org/dpdk-stable/commit/?h=17.08&id=907fe4fc263e This means the fix is not included into any DPDK 17.02.x used by NSB. Fortunately, a simple workaround consists of calling rte_eth_tx_queue_setup() before rte_eth_rx_queue_setup(). This change implements this simple workaround, in order to make PROX work, even with unfixed DPDK versions.

2018-07-26Initial support for DPDK 18.05Xavier Simonart1-3/+10
This patch makes PROX compile with DPDK 18.05. However some features are disabled or will not work as expected such as: "mem info" command "police" mode Those will need to be fixed later (see DPDK1805 within code).

2018-05-25Increase default mbuf size and code simplification/cleanupXavier Simonart1-6/+24
mbuf size was setup to achieve the best performance i.e. using the smallest mbuf and not segmenting packets. However this resulted in complex code, much dependent of the way the pmd are working e.g. a change(fix) in recent dpdk i40e implementation caused a 1782 (=1518+8+256) bytes mbuf to be too small to hold a 1518 bytes packets. Hence this change simplifies the mbuf size selection at the price of a potential decreases in performance - as more memory is now used. Except if jumbo frames are used, the mbuf size will now be the same for all modes. The packets will not be segmented except if jumbo frames are enabled. If jumbo frames are enabled, packets are by default segmented, except if the mbuf size is configured big enough in the config file.

2018-04-26Fix crc offloads.Xavier Simonart1-4/+4
When configuring a port, prox configures queue flags. For historitical reasons, offloads had to be disabled on some pmds. There is now an API to query the ports and gets their capabilities. This fix sets now the flags based on the capabilities, and not the driver name. Change-Id: Ic72d15001992f26910f653c70d31e4381fff8089 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2018-04-15Add support for reception of jumbo framesXavier Simonart1-6/+4
Jumbo frames are now supported through the addition of a "mtu" parameter of the port in the config file. Setting the mtu to a value higher than 1500 bytes will enable the reception of jumbo frames. In addition, the rte_eth_dev_set_mtu is now set for all pmds. Finally, setting mbuf_size does not set MEMPOOL_F_NO_SPREAD anymore. This option was only used for pure debugging. Big packets can be received using two ways - Using multiple "small" mbufs, i.e. around 2K. This is the default. - Using one big mbuf holding the whole packet. This can be enabled by setting a parameter mbuf_size in the receiving core configuration Change-Id: Idd60ad31f41c89f9522dff4d894af2696b7a2ea1 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2018-01-16Integrate irq mode into PROX (support display and command line)Xavier Simonart1-3/+5
irq mode can be used to show how a core is interrupted by other tasks. This mode does not handle packets. It only loops reading tsc. When the difference between two consecutive calls to rdtsc() is high then it means the core was interrupted. This task implementes the display, so that we can see a histogram of interrupts as well as the maximum, per core. Command line is also supported, through "show irq buckets" (too show the intervals of each buckets, in micrcoseconds), and the stats command line (showing the number of items in each buckets and the max)..
