This is the userspace components for the Linux Kernel's drivers/infiniband subsystem. Specifically this contains the userspace libraries for the following device nodes:
- /dev/infiniband/uverbsX (libibverbs)
- /dev/infiniband/rdma_cm (librdmacm)
- /dev/infiniband/umadX (libumad)
- /dev/infiniband/ucmX (libibcm, deprecated)
The userspace component of the libibverbs RDMA kernel drivers are included under the providers/ directory. Support for the following Kernel RDMA drivers is included:
- iw_cxgb3.ko
- iw_cxgb4.ko
- hfi1.ko
- i40iw.ko
- ib_qib.ko
- mlx4_ib.ko
- mlx5_ib.ko
- ib_mthca.ko
- iw_nes.ko
- ocrdma.ko
- rdma_rxe.ko
Additional service daemons are provided for:
- srp_daemon (ib_srp.ko)
- iwpmd (for iwarp kernel providers)
This project uses a cmake based build system. Quick start:
$ mkdir build
$ cd build
$ cmake -GNinja ..
$ ninjabuild/bin will contain the sample programs and build/lib will contain the shared libraries.
NOTE: It is not currently easy to run from the build directory, the plugins only load from the system path.
$ apt-get install build-essential cmake gcc libnl-3-dev libnl-route-3-dev ninja-build pkg-config valgrind$ dnf install cmake gcc libnl3-devel pkgconfig valgrind-devel ninja-buildNOTE: Fedora Core uses the name 'ninja-build' for the ninja command.
$ zypper install cmake gcc libnl3-devel ninja pkg-config valgrind-develInstall required packages:
$ yum install cmake gcc libnl3-devel make pkgconfig valgrind-develFor end users, the package can be built using GNU Make and the old cmake included with the distro:
$ mkdir build
$ cd build
$ cmake ..
$ makeDevelopers are suggested to install more modern tooling for the best experience.
$ yum install epel-release
$ yum install cmake3 unzip
$ curl -OL https://github.com/ninja-build/ninja/releases/download/v1.7.1/ninja-linux.zip
$ unzip ninja-linux.zip
$ install -m755 ninja /usr/local/bin/ninjaUse the 'cmake3' program in place of cmake in the above instructions.
