Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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.

These are additional patches for SRIOV support that came in after my primary patch set was submitted for review.

Comment 2 Doug Ledford 2012-03-20 16:17:05 UTC

The final set of patches I'm submitting are done.

Comment 4 Aristeu Rozanski 2012-03-23 19:32:18 UTC

Patch(es) available on kernel-2.6.32-255.el6

Comment 7 Zhang Kexin 2012-05-22 03:36:40 UTC

Hi Vladimir,
Could  you help testing this bug on latest snapshot please? Thank you!

Comment 8 Weibing Zhang 2012-05-24 10:18:43 UTC

It seems there is no num_vfs option for mlx4_en module. Can SR-IOV support for mlx4_en be tested via mlx4_core?

Comment 9 Doug Ledford 2012-05-29 18:26:25 UTC

It is standard that the num_vfs option is set via mlx4_core.

Comment 10 Weibing Zhang 2012-06-01 09:45:15 UTC

Run NIC driver test for mlx4_en on kernel-2.6.32-272 and all the tests passed.
[root@rdma4 ~]# modprobe -r mlx4_en
[root@rdma4 ~]# modprobe -r mlx4_ib
[root@rdma4 ~]# modprobe -r mlx4_core
[root@rdma4 ~]# modprobe mlx4_core num_vfs=1
Set SanityOnly.
