Description Michael Chan 2010-07-21 19:15:08 EDT
+++ This bug was initially created as a clone of Bug #568601 +++

As requested by John, this BZ separates the AER feature from the general update of the bnx2 driver in bug 568601.

John has proposed a patch for the AER support.  Broadcom QA is currently setting up an environment to test using aer-inject.

[PATCH] bnx2:  Add PCI Advanced Error Reporting.

This is the upstream patch we plan to send once net-next opens.  It is largely based on John's original patch.
Comment 2 Andrius Benokraitis 2010-08-09 10:09:29 EDT
Michael, exactly when do you plan on submitting this?
Comment 3 Michael Chan 2010-08-09 15:37:33 EDT
Dave Miller is not accepting any new features right now until net-next-2.6 opens.  It should open in about a week.  I'll be on vacation soon and will ask a co-worker to send the patch for me.  Thanks.
Comment 4 Andrius Benokraitis 2010-09-27 15:09:00 EDT
NOTE: this may not make RHEL 5.6 due to the development window for 5.6 Beta already being closed.
Comment 5 Michael Chan 2010-10-12 18:02:04 EDT
John, please also include this patch:


    bnx2: Enable AER on PCIE devices only

in addition to the 1st patch:


    bnx2: Add PCI Advanced Error Reporting support.
Comment 6 John Feeney 2010-10-14 12:45:53 EDT
I encorporated both AER commits provided in comment #5 in a kernel build. See http://people.redhat.com/jfeeney/.rhel5.6/kernel-2.6.18-222.el5.bz617024.1*
Comment 7 John Feeney 2010-10-19 13:49:16 EDT
There is a tool that can be used to twiddle this driver to inject the errors.
I would suggest downloading the code and reviewing
Comment 8 John Feeney 2010-10-21 15:01:43 EDT
I noticed that you set the verified field today. Does this mean that you successfully tested the kernel I provided in comment #6?

Just making sure. 
  Thanks if you did.

Hi John,

[root@pilot ~]# uname -a

Comment 10 John Feeney 2010-10-22 11:56:48 EDT
I have been asked for the details of the testing you performed. Would it be possible to provide them here?
Comment 11 Joshua powers 2010-10-25 10:27:48 EDT
Hi John,

We have a script that injects each of the types of errors to a specific bus and function. We did this with the bnx2 device and then reviewed messages to verify:

1) The correct error status bits were being set.
2) No additional error status bits were being set between tests.
3) The link was coming back up after each correctable error.
Comment 14 Jarod Wilson 2010-11-16 11:57:31 EST
in kernel-2.6.18-232.el5
You can download this test kernel (or newer) from http://people.redhat.com/jwilson/el5

Detailed testing feedback is always welcomed.
