base on RDMA core userspace libraries and daemons [![Build Status](https://dev.azure.com/ucfconsort/rdma-core/_apis/build/status/linux-rdma.rdma-core?branchName=master)](https://dev.azure.com/ucfconsort/rdma-core/_build/latest?definitionId=2&branchName=master) # RDMA Core Userspace Libraries and Daemons 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 (libibumad) The userspace component of the libibverbs RDMA kernel drivers are included under the providers/ directory. Support for the following Kernel RDMA drivers is included: - bnxt_re.ko - efa.ko - erdma.ko - iw_cxgb4.ko - hfi1.ko - hns-roce-hw-v2.ko - irdma.ko - ib_qib.ko - mana_ib.ko - mlx4_ib.ko - mlx5_ib.ko - ib_mthca.ko - ocrdma.ko - qedr.ko - rdma_rxe.ko - siw.ko - vmw_pvrdma.ko Additional service daemons are provided for: - srp_daemon (ib_srp.ko) - iwpmd (for iwarp kernel providers) - ibacm (for InfiniBand communication management assistant) # Building This project uses a cmake based build system. Quick start: ```sh $ bash build.sh ``` *build/bin* will contain the sample programs and *build/lib* will contain the shared libraries. The build is configured to run all the programs 'in-place' and cannot be installed. ### Debian Derived ```sh $ apt-get install build-essential cmake gcc libudev-dev libnl-3-dev libnl-route-3-dev ninja-build pkg-config valgrind python3-dev cython3 python3-docutils pandoc ``` Supported releases: * Debian 9 (stretch) or newer * Ubuntu 16.04 LTS (xenial) or newer ### Fedora, CentOS 8 ```sh $ dnf builddep redhat/rdma-core.spec ``` NOTE: Fedora Core uses the name 'ninja-build' for the 'ninja' command. ### openSUSE ```sh $ zypper install cmake gcc libnl3-devel libudev-devel ninja pkg-config valgrind-devel python3-devel python3-Cython python3-docutils pandoc ``` ## Building on CentOS 7, Amazon Linux 2 Install required packages: ```sh $ yum install cmake gcc libnl3-devel libudev-devel make pkgconfig valgrind-devel ``` Developers on CentOS 7 or Amazon Linux 2 are suggested to install more modern tooling for the best experience. CentOS 7: ```sh $ yum install epel-release $ yum install cmake3 ninja-build pandoc ``` Amazon Linux 2: ```sh $ amazon-linux-extras install epel $ yum install cmake3 ninja-build pandoc ``` NOTE: EPEL uses the name 'ninja-build' for the 'ninja' command, and 'cmake3' for the 'cmake' command. # Usage To set up software RDMA on an existing interface with either of the available drivers, use the following commands, substituting `<DRIVER>` with the name of the driver of your choice (`rdma_rxe` or `siw`) and `<TYPE>` with the type corresponding to the driver (`rxe` or `siw`). ``` # modprobe <DRIVER> # rdma link add <NAME> type <TYPE> netdev <DEVICE> ``` Please note that you need version of `iproute2` recent enough is required for the command above to work. You can use either `ibv_devices` or `rdma link` to verify that the device was successfully added. # Reporting bugs Bugs should be reported to the <linux-rdma@vger.kernel.org> mailing list In your bug report, please include: * Information about your system: - Linux distribution and version - Linux kernel and version - InfiniBand hardware and firmware version - ... any other relevant information * How to reproduce the bug. * If the bug is a crash, the exact output printed out when the crash occurred, including any kernel messages produced. # Submitting patches See [Contributing to rdma-core](Documentation/contributing.md). # Stable branches Stable versions are released regularly with backported fixes (see Documentation/stable.md) The current minimum version still maintained is 'v33.X' ", Assign "at most 3 tags" to the expected json: {"id":"2517","tags":[]} "only from the tags list I provide: [{"id":77,"name":"3d"},{"id":89,"name":"agent"},{"id":17,"name":"ai"},{"id":54,"name":"algorithm"},{"id":24,"name":"api"},{"id":44,"name":"authentication"},{"id":3,"name":"aws"},{"id":27,"name":"backend"},{"id":60,"name":"benchmark"},{"id":72,"name":"best-practices"},{"id":39,"name":"bitcoin"},{"id":37,"name":"blockchain"},{"id":1,"name":"blog"},{"id":45,"name":"bundler"},{"id":58,"name":"cache"},{"id":21,"name":"chat"},{"id":49,"name":"cicd"},{"id":4,"name":"cli"},{"id":64,"name":"cloud-native"},{"id":48,"name":"cms"},{"id":61,"name":"compiler"},{"id":68,"name":"containerization"},{"id":92,"name":"crm"},{"id":34,"name":"data"},{"id":47,"name":"database"},{"id":8,"name":"declarative-gui "},{"id":9,"name":"deploy-tool"},{"id":53,"name":"desktop-app"},{"id":6,"name":"dev-exp-lib"},{"id":59,"name":"dev-tool"},{"id":13,"name":"ecommerce"},{"id":26,"name":"editor"},{"id":66,"name":"emulator"},{"id":62,"name":"filesystem"},{"id":80,"name":"finance"},{"id":15,"name":"firmware"},{"id":73,"name":"for-fun"},{"id":2,"name":"framework"},{"id":11,"name":"frontend"},{"id":22,"name":"game"},{"id":81,"name":"game-engine "},{"id":23,"name":"graphql"},{"id":84,"name":"gui"},{"id":91,"name":"http"},{"id":5,"name":"http-client"},{"id":51,"name":"iac"},{"id":30,"name":"ide"},{"id":78,"name":"iot"},{"id":40,"name":"json"},{"id":83,"name":"julian"},{"id":38,"name":"k8s"},{"id":31,"name":"language"},{"id":10,"name":"learning-resource"},{"id":33,"name":"lib"},{"id":41,"name":"linter"},{"id":28,"name":"lms"},{"id":16,"name":"logging"},{"id":76,"name":"low-code"},{"id":90,"name":"message-queue"},{"id":42,"name":"mobile-app"},{"id":18,"name":"monitoring"},{"id":36,"name":"networking"},{"id":7,"name":"node-version"},{"id":55,"name":"nosql"},{"id":57,"name":"observability"},{"id":46,"name":"orm"},{"id":52,"name":"os"},{"id":14,"name":"parser"},{"id":74,"name":"react"},{"id":82,"name":"real-time"},{"id":56,"name":"robot"},{"id":65,"name":"runtime"},{"id":32,"name":"sdk"},{"id":71,"name":"search"},{"id":63,"name":"secrets"},{"id":25,"name":"security"},{"id":85,"name":"server"},{"id":86,"name":"serverless"},{"id":70,"name":"storage"},{"id":75,"name":"system-design"},{"id":79,"name":"terminal"},{"id":29,"name":"testing"},{"id":12,"name":"ui"},{"id":50,"name":"ux"},{"id":88,"name":"video"},{"id":20,"name":"web-app"},{"id":35,"name":"web-server"},{"id":43,"name":"webassembly"},{"id":69,"name":"workflow"},{"id":87,"name":"yaml"}]" returns me the "expected json"
