Thank you Sujal!<br>
<br>
As we await IBM's inclusion in the EWG would it be possible for you to include
the ehca driver code in OFED 1.1? The code can be extracted from Roland's git
tree: git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband.git ehca<br>

Hi Chet,<br>
<br>
I am copying Bill Boas and Jim Ryan (co-chair and chair respectively of
OpenFabrics) so that they are informed about this request. <br>
<br>
<br>
Hi Bill/Jim,<br>
<br>
IBM needs to be added as a EWG member so that they can start active work on
OFED releases.<br>
<br>
If I recall correctly, the process requires the BOD members to vote and approve
IBMs inclusion into EWG subsequent to IBM’s nomination into EWG.
Shawn has already approved IBM’s inclusion and we support that.
Could we initiate an electronic voting to accomplish this quickly?<br>
<br>
Thanks,<br>
<br>
Sujal<br>

Sujal, Shawn,<br>
<br>
I am following up to submit the names of Marcus Eder as IBM's representative to
the EWG within OpenFabrics with Nam Nguyen serving as his back-up. Marcus's
team developed and released the open source ehca drivers and are best
positioned to participate in OFA's EWG to support it for all future releases.<br>
Shawn, I appreciate your agreeing to support IBM's nomination.<br>
<br>
Please copy Marcus & Nam on any necessary follow-ups. Thx!<br>

Chet,<br>
<br>
That is great news. First, IBM should become a member of the Enterprise
Workgroup (EWG) within OpenFabrics and work toward qualifying and enhancing the
driver to meet the release criteria jointly defined by EWG. There is a
voting procedure where board members need to approve. Shawn, as the chair
of EWG, can initiate that process with EWG/OpenFabrics. <br>
<br>
After that, you should subscribe to the EWG mailing list and work with the OFED
release coordinator, <st1:PersonName w:st="on">Tziporet Koren</st1:PersonName>,
to get your driver included into OFED. Given the fact that OFED 1.1
release is imminent (in mid Sept), there may not be enough time for adequate
QA, so there is a possibility that eHCA support releases as technology preview
only in OFED 1.1 and goes to production status in a future release of
OFED. I believe eHCA support in OFED 1.0 was tech preview only – I
do not recall any of the EWG members testing the eHCA actively prior to OFED
1.0 release back in June.<br>
<br>
Thanks<br>

FYI: Our driver has been contained in OFED 1.0, but not in OFED 1.1-rc1

Hi,<br>
To be part of OFED you need to join the EWG and they need to approve adding IBM
support for the package.<br>
<br>
I cc Shawn from Cisco (Chairman of EWG) and Sujal from Mellanox and they can
help in driving this.<br>
After it's approved we can discuss the technical details how to add ehca
support to OFED 1.1<br>
