Manit Mahajan ##################################################################### Minutes ===================================================================== General Announcements * Can we reschedule this meeting to account for daylight saving time? * Will move the call 1 hour earlier going forward to account for daylight saving time. This brings the meeting to 13:00 UTC. ===================================================================== CI Status --------------------------------------------------------------------- UNH-IOL Community Lab * New DTS: * We are missing some DTS results (for Intel XL710) from this week due to a dpdk tarball naming conflict on the DUT. This failed “silently” from our perspective because we were not checking the DTS exit code and flagging non-zero codes in our CI alert system. We are adding that now and Dean will put in retests for the XL710 later today. * Minimum Kernel Version Test: * The UNH Lab is running build and unit tests off of a VM which is set to kernel 4.19 - the minimum tested kernel version according to DPDK docs. * QAT Crypto Test: * Cody at UNH has setup a dpdk-crypto-perf test (from legacy DTS) on the QAT crypto device which came with one of the Intel Xeon CPUs added to the lab in 2024. * We will share the performance metrics with Bruce Richardson/Intel and then enable reporting for this test * Baremetal testing maintenance: * We are moving around some NICs to newer systems, updating drivers, and other normal maintenance that we do on baremetal systems at the start of a release dev cycle * We are now reporting the dts-check-format label to patchwork --------------------------------------------------------------------- Intel Lab * None --------------------------------------------------------------------- Github Actions * Aaron has a pre-req patch ready to go for the recheck count. This is for the PW-CI project. --------------------------------------------------------------------- AWS * Patrick will reach out to Shai for an update --------------------------------------------------------------------- Loongarch Lab * None ===================================================================== DTS Improvements & Test Development * Smoke Tests Testsuite bugfixes: * There are two issues, one pertaining to a keyerror on the tests_config dictionary and the other pertaining to the regex which is used to capture the driver NICs are bound to from dpdk-devbind.py -s * DTS Packet Sniffer update: * No updates, but this is reviewed from Dean and Patrick * Performance TG update: * DTS Configuration and TestSuite API notes: * 1. Test_run.yaml: * app location * trex configuration * TestSuite Class facing functions: * define a packet X with scapy * call TestSuite.assess_performance_by_packet(packet X, duration Y) * This returns an instance of a new performance stats dataclass * TG internals notes: * Imports a series of TREX stateless API components * A set of one STLCLient, Stream and PacketBuilder are created. * Once created, the STLStream is started using the given duration. When completed, stats are gathered via stdout and put into the PerformanceStats dataclass. * DTS Roadmap * 1. TG abstraction rework (to facilitate performance TGs), testsuite API additions for perf workloads, and TREX class implementation * Luca raised that it may be best to leave the perf TGs as child classes of the current tg abstract class and simply not implement the capturing methods * Luca also raises that his asyncsniffer patchseries adds some new methods of collecting packets, such as collecting until a stop condition is met (like seeing packet X). This may split out packet send and packet capture from send_packet_and_capture(), making them independent. * 2. Write testsuite perf_single_core_fwd * 3. Write testsuite rte_flow * 4. Port VF support * 5. Docs improvements for new users * Luca has indicated that Thomas Wilks will contribute to this * 6. Rework packet send and receive functions in the Testsuite API towards supporting IP networking in an L3 environment * 7. DPDK Testsuite API: This will provide a stable API which will not be broken going forward (except at agreed upon intervals) * Moving existing testsuite functions to the context hierarchy * 8. RSS Support Testsuites * Work for this is basically done - reviews needed though: <a href="https://patchwork.dpdk.org/project/dpdk/list/?series=34713">https://patchwork.dpdk.org/project/dpdk/list/?series=34713</a> * 9. Update TestResult module in order to give a more human readable summary of the testsuites * 10. Improved interactive shell data collection and logging. * Add a file which exclusively logs the shell interactions * 11. Add dedicated file manager to handle passing files and artifacts between the test engine and nodes in a path agnostic manner * This will be a component of the new DPDK DTS API * 12. Flexible port binding * Give the opportunity to test suites to use all or part of the supplied port topology with the kernel drivers (instead of DPDK). Could be achieved with a decorator * This will require the Topology class to be aware of what’s truly available for DPDK and provide only the right ports for it * 13. Add pseudo-shell which handles background services. * <a href="https://patchwork.dpdk.org/project/dpdk/list/?series=34865">https://patchwork.dpdk.org/project/dpdk/list/?series=34865</a> * 14. L4 port packet matching: <a href="https://patchwork.dpdk.org/project/dpdk/list/?series=34805">https://patchwork.dpdk.org/project/dpdk/list/?series=34805</a> ===================================================================== Any other business * Next Meeting Apr 17, 2025 </div>
