There was an intel PMDs series that was merged a week ago which had some performance failures when it was going through the CI: https://patches.dpdk.org/project/dpdk/patch/01c94afcb0b1c2795c031afc872a8faf3f0db2b5.1749229651.git.anatoly.burakov@intel.com/ and: http://mails.dpdk.org/archives/test-report/2025-June/883654.html As you can see it causes roughly a 6% decrease in packets forwarded in the single core forwarding test with 64Byte frames and 512 txd/rxd. The delta tolerance on the single core forwarding test is 5%, so a 6% reduction in MPPS forwarded is a failure. This was merged into mainline 6 days ago, which is why some failures started to come in this week for the E810 Grace test. To double check this, on DPDK I checked out to: test/event: fix event vector adapter timeouts (2eca0f4cd5daf6cd54b8705f6f76f3003c923912) which directly precedes the Intel PMD patchseries, and ran the test and it forwarded the pre-regression MPPS that we expected. Then I checked out to net/intel: add common Tx mbuf recycle (f5fd081c86ae415515ab55cbacf10c9c50536ca1) and I ran the test and it had the 6% reduction in MPPS forwarded. Another thing to note is that regrettably the ARM Grace E810 test did not get run on the v7 (the final version) of this series, which meant the failure was not displayed on that version and that's probably why it was merged. We will look back into our job history and see why this test failed to report. Please let me know if you have any questions about the test, the testbed environment info, or anything else.

Hi we have an update about the single core forwarding test= on the ARM Grace server with the E810 100G Ice card. There was an intel PM= Ds series that was merged a week ago which had some performance failures wh= en it was going through the CI: https://patches.dpdk.org/project/dpdk/patch/01c94afcb0= b1c2795c031afc872a8faf3f0db2b5.1749229651.git.anatoly.burakov@intel.com/

and: http://mails.dpdk.org/archives/test-report/2025-June/883654= .html

As you can see it causes roughly a 6% decrease in packets = forwarded in the single core forwarding test with 64Byte frames and 512 txd= /rxd. The delta tolerance on the single core forwarding test is 5%, so a 6%= reduction in MPPS forwarded is a failure.

This was merged into mai= nline 6 days ago, which is why some failures started to come in this week f= or the E810 Grace test.

To double check this, on DPDK I checked out = to:

test/event: fix event vector adapter timeouts (2eca0f4cd5daf6cd= 54b8705f6f76f3003c923912) which directly precedes the Intel PMD patchseries= , and ran the test and it forwarded the pre-regression MPPS that we expecte= d.

Then I checked out to net/intel: add common Tx mbuf recycle (f5fd= 081c86ae415515ab55cbacf10c9c50536ca1)

and I ran the test and it had = the 6% reduction in MPPS forwarded.

Another thing to note is that re= grettably the ARM Grace E810 test did not get run on the v7 (the final vers= ion) of this series, which meant the failure was not displayed on that vers= ion and that's probably why it was merged. We will look back into our j= ob history and see why this test failed to report.

Please let me kno= w if you have any questions about the test, the testbed environment info, o= r anything else.
