RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Created attachment 1719667 [details]
client log for perftest result showing successful results on RHEL8.3 eSNAP runs for QEDR IW

Description of problem:

The two perftests with "-c RC" option fail due to the following error:

ERRNO: Cannot allocate memory.

This error takes place only on QEDR IW device, consistently. Started noticing this behavior from RHEL8.3 RC builds - RHEL-8.3.0-20200929.2 and used to pass on eSNAP#3 (RHEL-8.3.0-20200909.1) & iSNAP (RHEL-8.3.0-20200701.2) runs. However, this same behavior is now observed on these two builds, as well.

Additional info:

These two commands used run fine on RHEL-8.3.0-20200909.1 and prior builds; but now, the same failures are observed in them, as well. Refer to the attached test logs run with RHEL8.3.0-20200909.1

It seems the perftest beaker case had been updated. The flag '-I 128' had been removed.

Comment 4 Honggang LI 2020-10-09 09:20:50 UTC 
Because the flag '-I 128' had been removed from beaker case, the default optimal values for inline were used.
Unfortunately default optimal values are not suitable for qedr1 device in rdma-dev-02/03.
