We discussed people's progress towards our goal of getting the initial
backports for OFED-3.3 complete. The status is:
NES driver: Patches have been submitted but have not yet been applied.
Intel IB QIB Driver:
SLES 11 SP2; no backport patches were needed.
- RHEL 6.2 -- may need some backport patch(es), in progress
- 3.0, 3.1 and 3.2 kernels, in progress.
- we are still learning how all the pieces fit together, so we may have
patches.
- still targeting month-end.
Chelsio:
the cxgb3/4 backports are code-complete for 3.0, 3.1, and rhel6.2.
- testing and code review under way
- will submit these this week
There was a question that we need to discuss more in our next meeting.
It was what should we do if we find bugs in the upstream kernel code ?
Will there be a way to apply bug fix patches to the OFED tree in addition
To the backports ?
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@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.
