+## RoCE Configuration for Ubuntu
+
+To configure RoCE on the adapter for an Ubuntu host, RDMA must be installed and configured on the Ubuntu host. To configure and set up RoCE for Ubuntu 14.04.5/16.04.1 Linux:
+
+1. When you begin installing the Ubuntu server, verify if the basic packages, modules, and tools are available for Ethernet and RDMA. Log in as ROOT,and install all required packages.
+
+ a. Install the basic packages required for Ubuntu:
+
+ ```bash
+ apt-get install build-essential cmake gcc \
+ pkg-config vlan automake autoconf dkms git ninja-build \
+ libudev-dev libnl-3-dev libnl-route-3-dev valgrind python3-dev cython3 python3-docutils pandoc
+
+ ```
+ b. Install the following RDMA packages required for Ubuntu:
+ ```bash
+ apt-get install 鈥揻 libibverbs* librdma* libibcm.* libibmad.* libibumad*
+ ```
+
+ Or, Install from source code
+
+ ```bash
+ git clone https://github.com/linux-rdma/rdma-core.git
+ ```
+
+ ```bash
+ [ -d build ] || mkdir build
+ cd build
+ cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Release ..
+ cmake --build .
+ sudo cmake --build . --target install
+ ```
+
+ c.Install RDMA user space tools and libraries required for Ubuntu:
+
+ ```bash
+ apt-get install -f libtool ibutils ibverbs-utils \
+ rdmacm-utils infiniband-diags perftest librdmacm-dev \
+ libibverbs-dev numactl libnuma-dev libnl-3-200 \
+ libnl-route-3-200 libnl-route-3-dev libnl-utils
+ ```
+
+2. If the file /etc/udev/rules.d/40-rdma.rules does not exist, create it with the following content:
+
+ ```bash
+cat > /etc/udev/rules.d/40-rdma.rules << "EOF"
+KERNEL=="umad*", NAME="infiniband/%k"
+KERNEL=="issm*", NAME="infiniband/%k"
+KERNEL=="ucm*", NAME="infiniband/%k", MODE="0666"
+KERNEL=="uverbs*", NAME="infiniband/%k", MODE="0666"
+KERNEL=="ucma", NAME="infiniband/%k", MODE="0666"
+KERNEL=="rdma_cm", NAME="infiniband/%k", MODE="0666"
+EOF
+```
+
+3. Edit the /etc/security/limits.conf file to increase the size of memory, which can be locked by a non-root user. Add the following lines, and then log out:
+
+ ```bash
+ cat >> /etc/security/limits.conf << "EOF"
+ * soft memlock unlimited
+ * hard memlock unlimited
+ root soft memlock unlimited
+ root hard memlock unlimited
+ EOF
+ ```
+4. Log into the system again, or verify after reboot. Then issue the following command:
+ ```bash
+ulimit -l
+ ```
+You should get the output as `unlimited` .
+
+5. Reboot the system.
+
+6. To allow the device to be recognized as an InfiniBand device that can be used by OFED, install the FastLinQ package by issuing the following commands:
+ ```bash
+cd fastlinq-X.X.X.X
+make clean
+make install
+```
+7. Install the libqedr libraries to work with RDMA user space applications using one of the following command options:
+ Option 1:
+
+ ```bash
+ cd fastlinq-X.X.X.X
+ make libqedr_install
+ ```
+
+ Option 2:
+
+ ```bash
+ cd fastlinq-X.X.X.X/libqedr-X.X.X.X/
+ ./configure --prefix=/usr --libdir=${exec_prefix}/lib --sysconfdir=/etc make install
+ ```
+
+8. Before loading the QLogic Ethernet and RDMA drivers, uninstall the existing out-of-box or inbox drivers by issuing the following commands:
+
+ ```bash
+ modprobe 鈥搑 qede
+ depmod 鈥揳
+ modprobe -v qedr
+ ```
+
+9. Load the RDMA modules by issuing the following commands. You must perform this step whenever you reboot the system.
+
+ ```bash
+ modprobe rdma_cm
+ modprobe ib_uverbs
+ modprobe rdma_ucm
+ modprobe ib_ucm
+ modprobe ib_umad
+ ```
+
+10. To list RoCE devices, issue the following command:
+
+ ```bash
+ ibv_devinfo
+ ```
