Hi, I have been trying to implement a kernel module (kernel 4.12) that opens an Infiniband connection, but have run into difficulties. The call to ib_create_qp() fails with -EINVAL. I have successfully set up the completion queues and protection domain. I have called ib_query_port() beforehand, which helps (I get farther along) but the ib_create_qp() call still fails. >From userspace, I have no problems moving data over RoCE, so I'm assuming my hardware, kernel, OFED, etc are all OK. I have used the net/smc module extensively as a reference, but there seems to be something fundamental that I'm missing. How can I find out what's going wrong here?
