<br><font size=2 face="sans-serif">Hello Tziporet!</font>
<br><font size=2 face="sans-serif">First thanks for your support including
our ehca driver in OFED!</font>
<br><font size=2 face="sans-serif">At the moment we do have our code in
Roland's git tree git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband.git,
branch ehca. It is based on latest kernel version, ie. 2.6.18-rc4. As Roland
has stated in the mailing list of openib and linux kernel (lkml,
powerpc dev) we're targetting to merge ehca into 2.6.19. In the meanwhile
we have incorporated some received comments in our code and will release
a patch against Roland's git tree by tomorrow, Vladimir, I'd appreciate
if you could pull the code then from there for OFED 1.1-rc3. </font>
<br><font size=2 face="sans-serif">According to OpenIB Wiki resp. OpenIBFAQ
we have to support 2.6.12 as latest stable kernel version. So we'll test
this and provide a backport if necessary. That Wiki page also mentions
2.6.9. I'm wondering if backport for that version is mandatory or not.
Can you please clarify that?</font>
<br><font size=2 face="sans-serif">We'll provide you with a list of supported
platforms (HW and OS) in the next couple of days.</font>

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>

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>

Please copy Marcus & Nam on any necessary follow-ups. Thx!<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, Tziporet Koren, 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>

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
