Hi Marcus and Nam,
I am glad to work with you to include IBM driver (ehca) in OFED.
Note that we already created RC2 yesterday and plan to have RC next week
on Aug-30, so if we want to add ehca we need to move fast.
I guess you already understand the way we work - code should be compiled
against kernel 2.6.18 tree, and we have back-port patches for the
different OSes we support.
Since ehca is not yet in Linux best if you can setup a git tree with
ehca and its backport patches.
To add ehca you will need to work with Vlad (responsible for the build &
install scripts) and with Michael (maintains the kernel git tree).
Please reply if you can setup a git tree, and if not from where we
should take the code & backport patches.
Also we need to know if there are any platforms (HW & OS) that ehca does
not support.
Thanks,
Tziporet

Now sending this to the EWG email list. Mellanox and Cisco welcomes IBM
to EWG and inclusion of eHCA into OFED. I would like to open this up to
other members of EWG - Voltaire, SilverStorm, QLogic, for their
comments.
Tziporet: Marcus Eder will be IBM's representative to the EWG within
OpenFabrics with Nam Nguyen serving as his back-up. I understand they
will also serve as maintainers of the eHCA driver in OFED.

Sujal,
As we discussed yesterday, when the Board of Directors of the OF
Alliance approved the IWG they did not say they wanted to approve every
member of the group so the IWG is free to constitute itself as it wishes
to meet the tasks and goals the Board approved.
So please bring IBM into IWG ASAP if that is what the IWG members decide
to do.
Bill.

Spoke to Bill further on this yesterday. He will respond. The process
may be easier than what I laid out. Stay tuned.

Thank you Sujal!
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
Thx!

Hi Chet,
I am copying Bill Boas and Jim Ryan (co-chair and chair respectively of
OpenFabrics) so that they are informed about this request.
Hi Bill/Jim,
IBM needs to be added as a EWG member so that they can start active work
on OFED releases.
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?
Thanks,
Sujal

Sujal, Shawn,
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.
Shawn, I appreciate your agreeing to support IBM's nomination.
Please copy Marcus & Nam on any necessary follow-ups. Thx!

RE: ehca is not in OFED 1.1-rc1 anymore
Chet,
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.
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.
Thanks
Sujal

Sujal, Shawn,
My apologies if you have responded already. If not, could you let us
know what's needed to get our ehca driver included in OFED 1.1? Thx.

Hello Shawn and Sujal!
Could you please tell me the prerequisites if any we need to fulfilled
in order to get your approval for including our ehca driver in OFED 1.1?
FYI: Our driver has been contained in OFED 1.0, but not in OFED 1.1-rc1
anymore.
Due to the short timeframe ahead OFED 1.1 I'd appreciate your helps!

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

Hello Tziporet!
I realized that ehca is not listed and contained in OFED 1.1-rc1. Did we
miss something or can you please tell me what can we do to get ehca in
OFED1.1?
Thanks!

* x86_64 * x86 * ia64 * ppc64
Main changes from OFED-1.0:
===========================
o Bug fixes
o Enabled building 32-bit libraries on x86_64 and ppc64. Note:
sysfsutils
and sysfsutils-devel 32-bit required.
o Kernel code based on 2.6.18
o Kernel hot-plug support in uverbs - removing module wait till all user
applications release their HCA resources.
o Package sources (user space and kernel modules) are places under:
<prefix>/src/
Original kernel sources are not replaced
o RDS was removed from the OFED package
o Set options in CMA & uCMA
o OSM new features:
- Partition Manager (Pkey)
- Pre-computed routing load from file
- Primitive QoS - As technology preview
o SDP:
- Improved latency (13 usec with netperf tcprr)
- Implemented Naggle algorithm
- Memory leaks fixes
- Error handling added
o MPI:
- OSU - MVAPICH: Message coalescing to improve message rate
- Open MPI 1.1-1: see changes:
http://svn.open-mpi.org/svn/ompi/trunk/NEWS
- MPI tests: Replace to the new test versions from LLNL,
Intel, OSU
o SRP:
- Stability
o iSER:
- Stability
- Testing more platforms (e.g. ppc64 and ia64)
- Performance improvements
o Management:
- Add saquery tool
- Enhancement to ibnetdiscover tool with grouping function
- New ibutils package:
o Port error counter check
o Port performance counters dump
o Link width and Link Speed check by flag
o uDAPL:
- Scalability features needed for Intel MPI
- Code was updated from trunk
Limitations and known issues:
=============================
1. ipath driver compilation fails on all systems
2. iSER support in install script for SLES 10 is missing
3. SDP:
- 32 bit systems might run out of low memory when opening
hundreds of sockets.
- For Mellanox Sinai HCAs one must use latest FW version
(1.1.000).
Missing features that should be completed for RC2:
==================================================
1. SRP:
- Complete testing with DM (Device Mapper) - for high
availability
- New daemon
2. IPoIB: High availability support using a daemon in user level
3. SDP: support sending/receiving out of band data
4. Add Madeye utility
5. Fatal error support in mthca
