[ewg] FW: EWG/OFED meeting agenda for today Nov-13 2012

Tue Nov 20 09:59:36 PST 2012

Hi Woody,

I have heard back from Marty Schlining who is the engineer involved with all
the testing at UNH-IOL and his response is below. It appears that the
original concerns have been resolved but Bug 2395 presents a serious problem
for us if we are going to base OFED 3.5 on the older kernel.

Thanks

Rupert

Rupert,

Bart has made all of the changes required for OFED and ib_srp. The delay for
unloading ib_srp is expected at this time according to Bart. There are no
more error messages in the kernel log.

The main issue is this bug:

 <http://bugs.openfabrics.org/bugzilla/show_bug.cgi?id=2395> Bug 2395 -
Kernel crash using SRP extended sg descriptors, increased max_sectors_kb,
when running direct IO.

http://bugs.openfabrics.org/bugzilla/show_bug.cgi?id=2395

According to Bart, this is a kernel bug that was fixed in 2.6.38 or greater.
So, the new features in OFED 3.5 regarding ib_srp will crash the present
test setup. You only ran ½ of the ib_srp capabilities. Im not really sure
how to proceed here. If OFED 3.5 is released and it supports a kernel that
has this bug, then it is possible to crash the system. And, since DDN
supports this feature, we would not like a version of OFED that does not
work properly with RHEL 6.3, SL 6.3, etc.

We can talk more about this. Getting ready to leave for the day.

-Marty

Hi Marty,

The EWG is anxious to release RC3 and I know there have been several SRP
patches. I was able to successfully run the OFA SRP Test Plan while at SC12.

Can you provide me with a status update regarding your testing an whether
you think we are ready for RC3. I only see one open bug for SRP and there
has been no update since 10/26/2012. I remember seeing a response saying
that 20-20 seconds was expected behavior. If you feel there are other
issues, can you create a new but or provide me with a concise list of the
problems and the solutions you would like to see?

Thanks

Rupert

Well the meeting was short today with only attendance from the Intel QIB
team and SGI.

Perhaps we can get a status update from the Intel iWarp folks via email on
this thread ?

I also wanted to know from Rupert if he was able to test the final SRP fix
that was open last meeting, 

I know there was some delay in that testing due to Hurricane Sandy.

Rupert ?

So it looks like we are still a couple weeks away from getting the last
critical bugs resolved from Chelsio, as per Steves email
below. 

If anyone knows of any other outstanding Critical bugs still being
investigated, please respond on this email thread.

Hi All

Unfortunately I cannot attend the meeting today
Woody - I hope you can replace me

All we need to close today is whether Chelsio and Intel drivers are ready so
that Vlad can build RC3

I cannot attend today either.  Vipul is out for Diwali.  We have made great
progress, but I see 2 blocker bugs still.  Our goal will be to close them
out by the end of next week.
