Yes, please push this into your git tree (and please verify that
cross-build to all OS-es passes).
Further, please do it this way: add the patch in ofed-1.2.5

Roland, Ralph, all,
I'd like to get your opinion on the following matter:
OFED is backporting upstream rdma code to older kernels.
While doing so, I really take pains to keep the ported
code as close as possible to upstream original,
mostly by using preprocessor to implement, as closely
as possible

1.2.5 and 1.3 include sean_local_sa_*.patch
patches which implement local sa caching. It just isn't

Backport kmem_cache_zalloc to kernels <= 2.6.16.

I'm happy with stuff as it is: the ifdefs make it easy to figure
which version does the backport apply.
BTW, I think the same backport will be needed for older kernels as well, no?

Hmm, I thought about it some more.
kmem_cache struct is not exported on recent kernels,
so this might br hard to do.
So I think the patch is probably the right approach, after all.

Correct. A single QP can be used to send data to any SRQ that shares the
same domain.

Let's not do it this way.
I think the right thing is to implement kmem_cache_zalloc
by means of kmem_cache_allocand memset in kernel_addons.

- I envision implementing this sharing mechanism in kernel by means
of a per-device tree, with inode as a key and domain object
as a value.

ehca backports for kernel.org kernels seem to be broken.
1. Does anyone care enough to fix them? If not we'll disable
ehca in build for these kernels.
2. Could you upload kernels for RHEL4U5 and SLES10 ppc64?
This would make it possible for us to add it to nightly builds.

Guys,
I have 2 more patches to go in ofed_1_2/ofed_1_2_c.

How do you propose to do this?

Thanks, applied to 1.2.c and ofed_kernel.
Vlad already took 1.2.c, and will I guess take ofed_kernel
after it passes his checks.

Here's some background on what SRC is. This is basically slide 6 in Dror's
talk, for those that missed the talk.
* * *
SRC is an extension supported by recent Mellanox hardware
which is geared toward reducing the number of QPs
required for all-to-all communication on systems
with a high number

This calls for a separate document. From feedback from Sonoma I really assumed
people have it figured out.
Let's open a separate thread, and there I will try writing up
what SRC is from the protocol point o

More code examples:
Create an SRC QP, part of SRC domain:
attr.qp_type = IBV_QPT_SRC;
attr.src_domain = d;
qp = ibv_create_qp(pd, &attr);
Given remote SRQ number, send data to this SRQ over an SRC QP:
wr.src_remote_srq_num = src_remote_srq_num;
ib_post_se
Some code examples:
/* create a domain and share it: */
struct ibv_src_domain * d = ibv_get_new_src_domain(ctx);
int fd = open(path, O_CREAT | O_RDWR, mode);
ibv_share_src_domain(d, fd);
/* get a reference to a shared domain: */
int fd = open(path,
