Hi, I'm trying to test the recently merged siw module. I'm running kernel 5.3-rc5 (taken from the Ubuntu mainline-kernel repository [1]) on Ubuntu 18.04 (bionic). I also manually installed rdma-core 25.0 from tarball, using the included Debian packaging. I installed all the packages but ibacm. After booting the new kernel I manually loaded the kernel module by modprobe siw modprobe rdma_ucm Then ibv_devinfo shows: "No IB devices found". dmesg only shows: [ 29.856751] SoftiWARP attached According to this tutorial, [2] it should be enough to just load the siw module. (unlike RXE, where one needs to use rxe_cfg to set up the interface) Is this a bug in siw or just a configuration issue on my side? Thanks, Marcin [1] https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.3-rc5/ [2] https://budevg.github.io/posts/tutorials/2017/04/29/rdma-101-1.html
