Re: OFED 1.5.4.1 on Ubuntu 10.04 with Mellanox cards?

Sebastian,

Thank you for taking the time to explain these things!  It's a little
confusing ....

> Here a simple list of matching code:
> OFED-1.5.4  ---> kernel 3.2.x
> OFED-1.5.4.1 ---> kernel 3.3.x

(1) Is there a more-exhaustive list of the right kernel to use with
each OFED release?  I was going by the OFED docs (e.g. release notes),
which seemed to indicate that for 1.5.4.1, the "right" range of
kernels was (kernel.org: 2.6.30 - 3.1), and specific kernel versions
for various distros.

(2) I'm pretty familiar with adminstering Debian systems and building
debian packages, hacking their insides, alienizing, hacking that
process, etc.

(I -think- ;-) The only real question for me is, which versions, with
which patches, of the various bits, will work together with this RoCEE
card.

(3) I'm -not at all- familiar with the workflow/process that Debian
Developers use.  For instance, I don't really understand what you men
below:

Do you mean that the kernel-ib RPM in 1.5.4 is the code form the
2.6.30 kernel?  But then the list below doesn't seem to make sense.

is:

  (a) check out the stuff from svn.debian.org

  (b) pull source from the OFED repos user-space

  (c) -copy- that (latest) OFED source into the tree I checked-out
  from debian

  (d) make sure that the patches in the debian directories apply
  properly to the various shellscripts

  (e) build debian packages per usual

And per your instructions above, I believe you're saying I should be
using a 3.3.x kernel?

Thanks,
