The mechanism includes an algorithm which decides if and how to +change moderation parameters for a channel, usually by performing an analysis on +runtime data sampled from the system. Net DIM is such a mechanism. In each +iteration of the algorithm, it analyses a given sample of the data, compares it +to the previous sample and if required, it can decide to change some of the +interrupt moderation configuration fields. The data sample is composed of data +bandwidth, the number of packets and the number of events. The time between +samples is also measured. Net DIM compares the current and the previous data and +returns an adjusted interrupt moderation configuration object. In some cases, +the algorithm might decide not to change anything. The configuration fields are +the minimum duration (microseconds) allowed between events and the maximum +number of wanted packets per event. The Net DIM algorithm ascribes importance to +increase bandwidth over reducing interrupt rate. + + +Part II: The Net DIM Algorithm +=============================== + +Each iteration of the Net DIM algorithm follows these steps: +1. Calculates new data sample. +2. Compares it to previous sample. +3. Makes a decision - suggests interrupt moderation configuration fields. +4. Applies a schedule work function, which applies suggested configuration. + +The first two steps are straightforward, both the new and the previous data are +supplied by the driver registered to Net DIM. The previous data is the new data +supplied to the previous iteration. The comparison step checks the difference +between the new and previous data and decides on the result of the last step. +A step would result as "better" if bandwidth increases and as "worse" if +bandwidth reduces. If there is no change in bandwidth, the packet rate is +compared in a similar fashion - increase == "better" and decrease == "worse". +In case there is no change in the packet rate as well, the interrupt rate is +compared. Here the algorithm tries to optimize for lower interrupt rate so an +increase in the interrupt rate is considered "worse" and a decrease is +considered "better". Step #2 has an optimization for avoiding false results: it +only considers a difference between samples as valid if it is greater than a +certain percentage. Also, since Net DIM does not measure anything by itself, it +assumes the data provided by the driver is valid. + +Step #3 decides on the suggested configuration based on the result from step #2 +and the internal state of the algorithm. The states reflect the "direction" of +the algorithm: is it going left (reducing moderation), right (increasing +moderation) or standing still. Another optimization is that if a decision +to stay still is made multiple times, the interval between iterations of the +algorithm would increase in order to reduce calculation overhead. Also, after +"parking" on one of the most left or most right decisions, the algorithm may +decide to verify this decision by taking a step in the other direction. This is +done in order to avoid getting stuck in a "deep sleep" scenario. Once a +decision is made, an interrupt moderation configuration is selected from +the predefined profiles. + +The last step is to notify the registered driver that it should apply the +suggested configuration. This is done by scheduling a work function, defined by +the Net DIM API and provided by the registered driver. + +As you can see, Net DIM itself does not actively interact with the system. It +would have trouble making the correct decisions if the wrong data is supplied to +it and it would be useless if the work function would not apply the suggested +configuration. This does, however, allow the registered driver some room for +manoeuvre as it may provide partial data or ignore the algorithm suggestion +under some conditions. + + +Part III: Registering a Network Device to DIM +============================================== + +Net DIM API exposes the main function net_dim(struct net_dim *dim, +struct net_dim_sample end_sample). This function is the entry point to the Net +DIM algorithm and has to be called every time the driver would like to check if +it should change interrupt moderation parameters. The driver should provide two +data structures: struct net_dim and struct net_dim_sample. Struct net_dim +describes the state of DIM for a specific object (RX queue, TX queue, +other queues, etc.). This includes the current selected profile, previous data +samples, the callback function provided by the driver and more. +Struct net_dim_sample describes a data sample, which will be compared to the +data sample stored in struct net_dim in order to decide on the algorithm's next +step. The sample should include bytes, packets and interrupts, measured by +the driver. + +In order to use Net DIM from a networking driver, the driver needs to call the +main net_dim() function. The recommended method is to call net_dim() on each +interrupt. Since Net DIM has a built-in moderation and it might decide to skip +iterations under certain conditions, there is no need to moderate the net_dim() +calls as well. As mentioned above, the driver needs to provide an object of type +struct net_dim to the net_dim() function call. It is advised for each entity +using Net DIM to hold a struct net_dim as part of its data structure and use it +as the main Net DIM API object. The struct net_dim_sample should hold the latest +bytes, packets and interrupts count. No need to perform any calculations, just +include the raw data. + +The net_dim() call itself does not return anything. Instead Net DIM relies on +the driver to provide a callback function, which is called when the algorithm +decides to make a change in the interrupt moderation parameters. This callback +will be scheduled and run in a separate thread in order not to add overhead to +the data flow. After the work is done, Net DIM algorithm needs to be set to +the proper state in order to move to the next iteration. + + +Part IV: Example +================= + +The following code demonstrates how to register a driver to Net DIM.

Testing bridging +between 4-ports LAGs or 8-way ECMP requires many physical links that are +not always available. With the VRF-based approach one merely needs to +loopback more ports. + +These tests are written with switch ASICs in mind, but they can be run +on any Linux box using veth pairs to emulate physical loopbacks. + +Guidelines for Writing Tests +============================ + +o Where possible, reuse an existing topology for different tests instead + of recreating the same topology. +o Where possible, IPv6 and IPv4 addresses shall conform to RFC 3849 and + RFC 5737, respectively. +o Where possible, tests shall be written so that they can be reused by + multiple topologies and added to lib.sh. +o Checks shall be added to lib.sh for any external dependencies. +o Code shall be checked using ShellCheck [1] prior to submission. + +1. https://www.shellcheck.net/ diff --git a/tools/testing/selftests/net/forwarding/bridge_vlan_aware.sh b/tools/testing/selftests/net/forwarding/bridge_vlan_aware.sh new file mode 100755 index 000000000000..75d922438bc9 --- /dev/null +++ b/tools/testing/selftests/net/forwarding/bridge_vlan_aware.sh @@ -0,0 +1,88 @@ +#!/bin/bash +# SPDX-License-Identifier: GPL-2.0 + +NUM_NETIFS=4 +CHECK_TC="yes" +source lib.sh + +h1_create() +{ + simple_if_init $h1 192.0.2.1/24 2001:db8:1::1/64 +} + +h1_destroy() +{ + simple_if_fini $h1 192.0.2.1/24 2001:db8:1::1/64 +} + +h2_create() +{ + simple_if_init $h2 192.0.2.2/24 2001:db8:1::2/64 +} + +h2_destroy() +{ + simple_if_fini $h2 192.0.2.2/24 2001:db8:1::2/64 +} + +switch_create() +{ + #

This allows for last-minute adjustment +of the command. + +The stages are identified by the following strings: + + - pre (pre-suite) + - setup + - command + - verify + - teardown + - post (post-suite) + + +To write a plugin, you need to inherit from TdcPlugin in +TdcPlugin.py. To use the plugin, you have to put the +implementation file in plugin-lib, and add a symbolic link to it from +plugins. It will be detected at run time and invoked at the +appropriate times. There are a few examples in the plugin-lib +directory: + + - rootPlugin.py: + implements the enforcement of running as root + - nsPlugin.py: + sets up a network namespace and runs all commands in that namespace + - valgrindPlugin.py + runs each command in the execute stage under valgrind, + and checks for leaks. + This plugin will output an extra test for each test in the test file, + one is the existing output as to whether the test passed or failed, + and the other is a test whether the command leaked memory or not. + (This one is a preliminary version, it may not work quite right yet, + but the overall template is there and it should only need tweaks.)
