[ewg] EWG/OFED meeting agenda for today (May 15, 2012) - Meeting Minutes

[Woodruff, Robert J]

The decision was made to move the kernel version to 3.3 rather than 3.2
and thus the next OFED release will be called OFED-3.3 and is scheduled
to release at the end of July.

Will there be OFED-3.2 GA and what is the date for it?

Thank you.

There is a way.  There are directories in the compat-rdma repository 
that get applied optionally with the admin_rdma.sh script:

linux-next-pending - these are patches you've submitted upstream but 
haven't been merged yet.

linux-next-cherry-picks - these are patches from upstream that we want 
in ofed but are too big or whatever to get pulled into the linux-stable 
tree.

crap - this directory holds patches that would never go upstream for 
whatever reason.

There are README files in each of these that explain their intended purpose.

And admin_rdma.sh allows pulling from them optionally:

[swise at build compat-rdma]$ ./scripts/admin_rdma.sh -?
Unexpected argument passed: -?
Usage: ./scripts/admin_rdma.sh [ refresh] [ --help | -h | -s | -n | -p | 
-c ]
    refresh - will update your all your patch offsets using quilt
         -s - get and apply pending-stable/ fixes purging old files there
         -n - apply the patches linux-next-cherry-picks directory
         -p - apply the patches on the linux-next-pending directory
         -c - apply the patches on the crap directory

Chelsio will have candidates for linux-next-cherry-picks up coming.


Steve.
