Hi
I am not sure if user space stuff can be posted here. I didn't see any other mail archive for user libverbs or perftest.
I stumbled across what looks like a portability issue. We are testing ibverbs on newly developed IB driver on our microblaze(32 bit) platform with xilinx rdma nic HW. While running ib_read_bw (server on microblaze and client on mlnx connectx-4), I found the client feeding a swapped VA. I narrowed it down to struct pingpong_dest. The size of this structure is 52bytes on 32bit system and 56bytes on 64bit x86 system with connect-x4.
I did a quick test with __attribute__((packed)) macro on struct pingpong_dest and I now see correct VA coming back from client via RETH.
So, is perftest/rdma-core ever tested with 32bit systems ? ib_read_bw --version shows 5.5. In config.h I have HAVE_ENDIAN 1.
