Description

The info in comment #1 mention Xen, however this is not a Xen specific bug. Neterion have shown same issue on bare metal case, and both bare metal and Xen are using the same PCI enumeration and resource reservation code. I have updated the bug to be against kernel, and made it dependent on BZ# 523341 which is a generic entry for this resource allocation issue. Masroor, can you please verify here in this BZ that the patched kernel available at: http://et.redhat.com/~chrisw/rhel5/5.5/bz523341/ fixes the issue for you? Hi Chris, I have upgraded to kernel-xen-2.6.18-190.el5.bz523341.x86_64.rpm which fixes this issue. Thanks, Masroor Hi Chris, Can this fix be included as part of a 5.5.z errata and 5.6? This will enable users to run the X3100 with SRIOV enabled. Thanks, Ram Chris, is this patch already included in the kernel planned for 5.6? If not, are there plans to submit it and we will likely require an exception to have it considered. This bug fix is a pre-req to a driver update required my some high-profile customers that plan to use the Exar NIC in their Red Hat certified servers. Per Ram Vepa in a telecon 6/14, patches submitted and accepted upstream. They have been running a patched kernel from Chris Wright since last September. Patches need to be attached to this bug by 8/01. Chris, do we have the patches POSTed to rhkernel and approved for 5.6? Note that the patch submission date is Aug 13 (not Aug 1 above) but they must be reviewed and approved by that date. Requesting exception until NEEDINFO satisfied. In response to comment #7, Don Dutile has 3-part patch set he's working for 5.6. Removing NEEDINFO. Installed RHEL 5.6 Beta (snapshot1) image and verified that the driver (version 2.0.8.20182-k) loads successfully in SRIOV mode. PF and all the VFs get enumerated properly and are functional. Also verified that the passthrough configuration works by attaching the PCI functions to 2 VMs and running traffic between the VMs and also to the remote machine.
