Should be able to largely do the same thing as the json files which old DTS outputs. * https://bugs.dpdk.org/show_bug.cgi?id=3D1363 * Patrick Robbto comment with any suggestions * UNH is starting to experiment with the flow API and writing testsuite(s) for it. * Having some difficulty checking device capabilities. There is a testpmd validate function which can be run for flow rules, but behavior from NICs after applying flow rules seems unreliable - we need to dig more and figure out whether our implementation is poor, testpmd support for flow api is poor, driver flow rule validation is lacking, or something else. =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Patch discussions * Thomas has indicated he will look at the DTS patches which are ready(docs gen, testpmd context manager, interactive shell output gathering) this week for RC3 * Docs generation * Thomas is going to provide a review * The part where we link the DTS api docs with the Doxygen landing page needs to be reviewed, so there is a link from DPDK docs to the DTS docs. * Testpmd context manager * Has been reviewed by everyone and is final * Improve interactive shell output gathering * Ready * Capabilities patch * Almost ready, but Juraj * needs to add support for getting capabilities from show port info * Show rxq info vs show rx_queue offload. Which is needed for our testcase? * There was an email send in the Spring about checking for scatter capability * Juraj is looking into the scatter capabilities more: * Jeremy: The first testcase should be based on what the port natively supports (maybe show rxq info {port} {queue}), and the second testcase should be based on whether the scatter capability can be offloaded to the NIC (show port {port} rx_offload capabilities) * It should be possible to check capabilities for the flow API too by using the testpmd flow rule validate command. Once we are confident with the rte_flow testsuite, we can add this part * Queue_Region testsuite: * Tests some comments in testpmd for the i40e driver * This uses a private API, and is exclusively for i40e * The driver feature is not supported in DPDK * It makes sense to avoid working on this testsuite for now, but we can come back to it * Blocklist: * UNH needs to provide a tested-by tag and reviews tag once it=E2=80=99= s ran on our hardware * Mac Filter: * Jeremy has provided a review, reviews from others requested * Dual VLAN * Basically the same as the single VLAN testsuite which Dean has submitted, but for 2 VLANs * There was a testcase for extended VLANs in old DTS. And a comment that says that extended VLANs makes filtering =E2=80=9Cwork normally=E2=80= =9D on i40e... it=E2=80=99s not clear what this means, but the VLAN strip, insert, and filter functions should work without extended VLAN range. * TPID support can come with a future version of this testsuite, but would include implementation of a capability check * Speed Capabilities: * Alex is looking at this testsuite, but it relies on defining a testsuite config file, something not needed for all other testsuites written so far * Dynamic queue is out waiting for review * Jumbo frames * Waiting on Ferruh to get back on the issue Nick was facing * Hoping that he will be able to expand more on what =E2=80=93max-pkt-len is trying to do and why it doesn=E2=80=99t completely = work. * The command seems to be shaving off certain number of bytes from the MTU (seemingly in an attempt to account for different PMDs supporting different ethernet overheads) =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Bugzilla discussions * None =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Any other business * Next meeting Aug 1, 2024
