I've modified rping to set O_NONBLOCKING on /dev/rdma_cm on the event channel (rdma_create_event_channel) which fails like this:
9997 rping CALL openat(AT_FDCWD,0x800a42708,0x100002<O_RDWR|O_CLOEXEC>,<unused>0)
9997 rping NAMI "/dev/rdma_cm"
9997 rping RET openat 3
9997 rping CALL fcntl(0x3,F_SETFL,0x6<O_RDWR|O_NONBLOCK>)
9997 rping RET fcntl -1 errno 25 Inappropriate ioctl for device
Is this not supported for some reason? This is with the latest OFED v3.2 patches by Hans.
The manpage for rdma_create_event_channel seems to state you can set non-blocking on it.
