* dpif-netdev: Per-port configurable EMC.Ilya Maximets2019-01-181-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | Conditional EMC insert helps a lot in scenarios with high numbers of parallel flows, but in current implementation this option affects all the threads and ports at once. There are scenarios where we have different number of flows on different ports. For example, if one of the VMs encapsulates traffic using additional headers, it will receive large number of flows but only few flows will come out of this VM. In this scenario it's much faster to use EMC instead of classifier for traffic from the VM, but it's better to disable EMC for the traffic which flows to VM. To handle above issue introduced 'emc-enable' configurable to enable/disable EMC on a per-port basis. Ex.: ovs-vsctl set interface dpdk0 other_config:emc-enable=false EMC probability kept as is and it works for all the ports with 'emc-enable=true'.

* rhel: Split OpenvSwitch and OVN packagesNuman Siddique2019-01-161-4/+13
| | | | | | | | | | | | | | | | | | | | | | Up until now, OVN rpms were generated as sub packages of OpenvSwitch. This patch now splits it and makes OVN rpms independent. A new spec file - ovn-fedora.spec.in is added for this. The openvswitch-fedora.spec.in has been modified to create only OpenvSwitch packages. Since we are not splitting the OVN code, the spec files run the same build procedure. Only the required binaries/files are copied into the rpms. The new package names will be ovn, ovn-common, ovn-central, ovn-host, ovn-vtep and ovn-docker.

* Adding support for PMD auto load balancingNitin Katiyar2019-01-161-0/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Port rx queues that have not been statically assigned to PMDs are currently assigned based on periodically sampled load measurements. The assignment is performed at specific instances – port addition, port deletion, upon reassignment request via CLI etc. Due to change in traffic pattern over time it can cause uneven load among the PMDs and thus resulting in lower overall throughout. This patch enables the support of auto load balancing of PMDs based on measured load of RX queues. Each PMD measures the processing load for each of its associated queues every 10 seconds. If the aggregated PMD load reaches 95% for 6 consecutive intervals then PMD considers itself to be overloaded. If any PMD is overloaded, a dry-run of the PMD assignment algorithm is performed by OVS main thread. The dry-run does NOT change the existing queue to PMD assignments. If the resultant mapping of dry-run indicates an improved distribution of the load then the actual reassignment will be performed. The automatic rebalancing will be disabled by default and has to be enabled via configuration option. The interval (in minutes) between two consecutive rebalancing can also be configured via CLI, default is 1 min. Following example commands can be used to set the auto-lb params: ovs-vsctl set open_vswitch . other_config:pmd-auto-lb="true" ovs-vsctl set open_vswitch . other_config:pmd-auto-lb-rebalance-intvl="5" Co-authored-by: Rohith Basavaraja <rohith.basavaraja@gmail.com> Co-authored-by: Venkatesan Pradeep <venkatesan.pradeep@ericsson.com> Signed-off-by: Rohith Basavaraja <rohith.basavaraja@gmail.com> Signed-off-by: Venkatesan Pradeep <venkatesan.pradeep@ericsson.com> Signed-off-by: Nitin Katiyar <nitin.katiyar@ericsson.com> Acked-by: Kevin Traynor <ktraynor@redhat.com> Tested-by: Kevin Traynor <ktraynor@redhat.com> Signed-off-by: Ian Stokes <ian.stokes@intel.com>

* ovn-sb.ovsschema: Avoid duplicated IPs in Encap table.Han Zhou2018-12-271-0/+28
| | | | | | | | | | | | | | | | | | | | When adding a new chassis, if there is an old chassis with same IP existed in Encap table, it is allowed to be added today. However, allowing it to be added results in problems: 1. The new chassis cannot work because none of the other chassises are able to create tunnel to it, because of the IP confliction with already existed tunnel to the old chassis. 2. All the other chassises will continuously retry creating the tunnel and complaining about the error. So, instead of hiding the problem, it is better to expose it while trying to add the second chassis with duplicated IP. This patch ensures it from the ovsdb schema.

* dpdk: Update to use DPDK 18.11.Ophir Munk2018-12-133-10/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds support for DPDK v18.11, it includes the following changes. 1. Enable compilation and linkage with dpdk 18.11.0 The following dpdk commits which were introduced after dpdk 17.11.x require OVS updates to accommodate to the dpdk changes. - ce17edde ("ethdev: introduce Rx queue offloads API") - ab3ce1e0 ("ethdev: remove old offload API") - c06ddf96 ("meter: add configuration profile") - e58638c3 ("ethdev: fix TPID handling in flow API") - cd8c7c7c ("ethdev: replace bus specific struct with generic dev") - ac8d22de ("ethdev: flatten RSS configuration in flow API") 2. Limit configured rss hash functions to only those supported by the eth device. 3. Set default RSS key in struct action_rss_data, required by OVS commit- e8a2b5bf ("netdev-dpdk: implement flow offload with rte flow") when configured with "other_config:hw-offload=true". 4. DEV_RX_OFFLOAD_CRC_STRIP has been removed from DPDK 18.11. DEV_RX_OFFLOAD_KEEP_CRC can now be used to keep the CRC. Use the correct flag and check it is supported. 5. rte_eth_dev_attach/detach have been removed from DPDK 18.11. Replace them with rte_dev_probe/remove. 6. Update docs and travis to use DPDK18.11. This commit squashes the following commits present on the dpdk-latest branch: 7f021f902bb3 ("netdev-dpdk: Upgrade to dpdk v18.08") 270d9216f1ed ("netdev-dpdk: Set scatter based on capabilities") bef2cdc8f412 ("netdev-dpdk: Fix returning the field of malloced struct.") 73c1a65167fc ("redhat: change variable used for non-root user support") eb485f60ce44 ("dpdk: Update to use DPDK 18.11.")

* netdev-dpdk: Add mbuf HEADROOM after alignment.Tiago Lam2018-11-281-14/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit dfaf00e started using the result of dpdk_buf_size() to calculate the available size on each mbuf, as opposed to using the previous MBUF_SIZE macro. However, this was calculating the mbuf size by adding up the MTU with RTE_PKTMBUF_HEADROOM and only then aligning to NETDEV_DPDK_MBUF_ALIGN. Instead, the accounting for the RTE_PKTMBUF_HEADROOM should only happen after alignment, as per below. Before alignment: ROUNDUP(MTU(1500) + RTE_PKTMBUF_HEADROOM(128), 1024) = 2048 After aligment: ROUNDUP(MTU(1500), 1024) + 128 = 2176 This might seem insignificant, however, it might have performance implications in DPDK, where each mbuf is expected to have 2k + RTE_PKTMBUF_HEADROOM of available space. This is because not only some NICs have course grained alignments of 1k, they will also take RTE_PKTMBUF_HEADROOM bytes from the overall available space in an mbuf when setting up their Rx requirements. Thus, only the "After alignment" case above would guarantee a 2k of available room, as the "Before alignment" would report only 1920B.

| * netdev-dpdk: fix mbuf sizingMark Kavanagh2018-11-021-14/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are numerous factors that must be considered when calculating the size of an mbuf: - the data portion of the mbuf must be sized in accordance With Rx buffer alignment (typically 1024B). So, for example, in order to successfully receive and capture a 1500B packet, mbufs with a data portion of size 2048B must be used. - in OvS, the elements that comprise an mbuf are: * the dp packet, which includes a struct rte mbuf (704B) * RTE_PKTMBUF_HEADROOM (128B) * packet data (aligned to 1k, as previously described) * RTE_PKTMBUF_TAILROOM (typically 0) Some PMDs require that the total mbuf size (i.e. the total sum of all of the above-listed components' lengths) is cache-aligned. To satisfy this requirement, it may be necessary to round up the total mbuf size with respect to cacheline size. In doing so, it's possible that the dp_packet's data portion is inadvertently increased in size, such that it no longer adheres to Rx buffer alignment. Consequently, the following property of the mbuf no longer holds true: mbuf.data_len == mbuf.buf_len - mbuf.data_off This creates a problem in the case of multi-segment mbufs, where that assumption is assumed to be true for all but the final segment in an mbuf chain. Resolve this issue by adjusting the size of the mbuf's private data portion, as opposed to the packet data portion when aligning mbuf size to cachelines.

| | | | | | | | | | | | | | | | | | | | | | | | Prior to OVS 2.9 automatic assignment of Rxqs to PMDs (i.e. CPUs) was done by round-robin. That was changed in OVS 2.9 to ordering the Rxqs based on their measured processing cycles. This was to assign the busiest Rxqs to different PMDs, improving aggregate throughput. For the most part the new scheme should be better, but there could be situations where a user prefers a simple round-robin scheme because Rxqs from a single port are more likely to be spread across multiple PMDs, and/or traffic is very bursty/unpredictable. Add 'pmd-rxq-assign' config to allow a user to select round-robin based assignment.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | abs_file_name() believed that a file name that begins with / or contains : is absolute and that any other file name is relative. On Windows, this is wrong in at least the following ways: * / and \ are interchangeable on Windows. * A name that begins with \\ or // is also absolute. * A name that begins with X: but not X:\ is not absolute. * A name with : in some position other than the second position is not absolute (although it might not be valid either?). Furthermore, Windows has more than one current working directory (one per volume letter), so trying to make a file name absolute by just prefixing the current working directory for the current volume results in silliness. This patch attempts to fix the problem. This makes OVS link against shlwapi, which is needed to use PathIsRelative(). Found by inspection.

* Docs: Improve OVS DPDK version mapping notice.Ian Stokes2018-07-242-4/+8
| | | | | | | | | | | | | A common issue is users pairing the incorrect version of OVS to DPDK when working outside of the build tree. To avoid this, this commit updates the OVS DPDK documentation to explicitly flag that users should consult the OVS to DPDK release mapping in FAQ if working outside of the OVS build tree.

* dpif-netdev: Add SMC cache after EMC cacheYipeng Wang2018-07-241-0/+15
| | | | | | | | | | | | | | | | | | | | | | This patch adds a signature match cache (SMC) after exact match cache (EMC). The difference between SMC and EMC is SMC only stores a signature of a flow thus it is much more memory efficient. With same memory space, EMC can store 8k flows while SMC can store 1M flows. It is generally beneficial to turn on SMC but turn off EMC when traffic flow count is much larger than EMC size. SMC cache will map a signature to an dp_netdev_flow index in flow_table. Thus, we add two new APIs in cmap for lookup key by index and lookup index by key. For now, SMC is an experimental feature that it is turned off by default. One can turn it on using ovsdb options.

* rhel: rename openvswitch kmod rhel6 spec fileMartin Xu2018-07-121-4/+3
| | | | | | | | | | | | | | | | | | This patch only affects rhel6 spec file. The rhel6 kmod spec file is renamed from openvswitch-kmod-rhel6.spec to kmod-openvswitch-rhel6.spec . This is to prepare for the next patches to support building multiple kernel versions in the main package. The rename makes the spec file consistent with the resulted kmod-openvswitch-<version>.rpm, which is the real package with kernel module files.
