6 Quick Start Setup Script
7 ========================
9 The dpdk-setup.sh script, found in the usertools subdirectory, allows the user to perform the following tasks:
11 * Build the DPDK libraries
13 * Insert and remove the DPDK IGB_UIO kernel module
15 * Insert and remove VFIO kernel modules
17 * Insert and remove the DPDK KNI kernel module
19 * Create and delete hugepages for NUMA and non-NUMA cases
21 * View network port status and reserve ports for DPDK application use
23 * Set up permissions for using VFIO as a non-privileged user
25 * Run the test and testpmd applications
27 * Look at hugepages in the meminfo
29 * List hugepages in ``/mnt/huge``
31 * Remove built DPDK libraries
33 Once these steps have been completed for one of the EAL targets,
34 the user may compile their own application that links in the EAL libraries to create the DPDK image.
39 The dpdk-setup.sh script is logically organized into a series of steps that a user performs in sequence.
40 Each step provides a number of options that guide the user to completing the desired task.
41 The following is a brief synopsis of each step.
43 **Step 1: Build DPDK Libraries**
45 Initially, the user must select a DPDK target to choose the correct target type and compiler options to use when building the libraries.
47 The user must have all libraries, modules, updates and compilers installed in the system prior to this,
48 as described in the earlier chapters in this Getting Started Guide.
50 **Step 2: Setup Environment**
52 The user configures the Linux* environment to support the running of DPDK applications.
53 Hugepages can be set up for NUMA or non-NUMA systems. Any existing hugepages will be removed.
54 The DPDK kernel module that is needed can also be inserted in this step,
55 and network ports may be bound to this module for DPDK application use.
57 **Step 3: Run an Application**
59 The user may run the test application once the other steps have been performed.
60 The test application allows the user to run a series of functional tests for the DPDK.
61 The testpmd application, which supports the receiving and sending of packets, can also be run.
63 **Step 4: Examining the System**
65 This step provides some tools for examining the status of hugepage mappings.
67 **Step 5: System Cleanup**
69 The final step has options for restoring the system to its original state.
74 The following are some example of how to use the dpdk-setup.sh script.
75 The script should be run using the source command.
76 Some options in the script prompt the user for further data before proceeding.
80 The dpdk-setup.sh script should be run with root privileges.

199 The following selection demonstrates the creation of hugepages in a NUMA system.
200 1024 2 MByte pages are assigned to each node.
201 The result is that the application should use -m 4096 for starting the application to access both memory areas
202 (this is done automatically if the -m option is not provided).
206 If prompts are displayed to remove temporary files, type 'y'.

214 Input the number of 2MB pages for each node
215 Example: to have 128MB of hugepages available per node,
216 enter '64' to reserve 64 * 2MB pages on each node
217 Number of pages for node0: 1024
218 Number of pages for node1: 1024

222 The following selection demonstrates the launch of the test application to run on a single core.
224 .. code-block:: console
228 Enter hex bitmask of cores to execute test app on
229 Example: to execute app on cores 0 to 7, enter 0xff
232 EAL: coremask set to 1
233 EAL: Detected lcore 0 on socket 0
235 EAL: Master core 0 is ready (tid=1b2ad720)
241 Once the user has run the dpdk-setup.sh script, built one of the EAL targets and set up hugepages (if using one of the Linux EAL targets),
242 the user can then move on to building and running their application or one of the examples provided.
244 The examples in the /examples directory provide a good starting point to gain an understanding of the operation of the DPDK.
245 The following command sequence shows how the helloworld sample application is built and run.
246 As recommended in Section 4.2.1 , "Logical Core Use by Applications",
247 the logical core layout of the platform should be determined when selecting a core mask to use for an application.
