We investigated a lot this failure and it appears on specific and very
old GCC 4.4.

http://marc.info/?t=147614305200001&r=1&w=2

* [PATCH V3] i40iw: Add Quality of Service support
From: Henry Orosco @ 2016-10-11 2:12 UTC (permalink / raw)
To: dledford-H+wXaHxf7aLQT0dZR+AlfA
Cc: linux-rdma-u79uwXL29TY76Z2rM5mHXA,
e1000-rdma-5NWGOfrQmneRv+LV9MX5uipxlwaOVQ5f, Henry Orosco
Add support for QoS on QPs. Upon device initialization,
a map is created from user priority to queue set
handles. On QP creation, use ToS to look up the queue
set handle for use with the QP.

V3:
- Replace deprecated create_singlethread_workqueue with
alloc_ordered_workqueue.
V2:
- Fix i40iw_cm.c and i40iw_ctrl.c mode to 100644.

I don't think so. The issue will happen every time the user is calling
ibportstate
with direct routing (-D argument) irrespective of wether the local LID
for switch
port 0 is configured or not.

Right, ninja puts everything onto STDOUT as part of 'output-sync'
operation. That is usually not a problem..
If you are asking for the 'quietest' build then this hack will do it:
$ ninja | grep -v "^\["

That would also work. But if there is a space anywhere in the path in
which the rdma-core repository exists, mkdir $BUILDDIR will have to be
changed into mkdir "$BUILDDIR".

No, sparse only outputs to SDTERR. But for some reason the rdma-core
build system multiplexes this back into STDOUT.

If I understand you, you want to split STDOUT and STDERR because
sparse puts differentiated output on each FD?
There is a thread on the ninja list about fixing this, and here is a
proposed patch
https://github.com/dendy/ninja/commit/62564251afdafd9926fde363035807fb482ab0b9
But looks like it is not in main line.
I think the simplest approach for you will be to use make when doing
this kind of work:
$ mkdir build-make
$ cd build-make
$ CC=cgcc cmake
$ make 1> a 2> b

Hello Christoph,
Have you considered to make this script stop immediately if one of the
steps fails, e.g. as follows?
mkdir -p "$BUILDDIR" &&
cd build &&
cmake -G Ninja .. &&
ninja
Thanks,
Bart.

Hello Diego,
Do you perhaps have edit rights for that kernel newbies page? If so, can
you correct the information about the SoftRoCE driver? The SoftRoCE
driver went upstream in kernel v4.8 so I think the reference to the
out-of-tree https://github.com/SoftRoCE/rxe-dev kernel driver should be
removed. And since the https://github.com/SoftRoCE/librxe-dev repository
has been superseded by the https://github.com/linux-rdma/rdma-core
repository, please change the reference to https://github.com/SoftRoCE/
into https://github.com/linux-rdma/rdma-core.
PS: the linux-rdma mailing list is the mailing list on which the
SoftRoCE driver was discussed before it was accepted upstream.
Thanks,
Bart.

Hi Jason,
what's the best way to generate a log of the compiler errors with the
shiny new rdma-core build system? With make I'd do make 2>err.log
but with the new build system the verbose build output and the errors
are mixed in the same stream, so this isn't possible anymore.
With the fairly large number of warnings from sparse this is rather
annoying.

* [PATCH] cxgb4: missing dereference in poll_cq
From: Christoph Hellwig @ 2016-10-10 15:27 UTC (permalink / raw)
To: swise-7bPotxP6k4+P2YhJcF5u+vpXobYPEAuW,
linux-rdma-u79uwXL29TY76Z2rM5mHXA
Sparse complains about using plain integer as NULL pointer here, but
I suspect we really want to check the value anyway, and Steve
confirmed that's indeed the case.

Should the following be added here to make it clearer:
in case where local LID for switch port 0 is not yet configured.
