Subject: [dpdk-dev] [PATCH 0/3] Add support for using a config file for DPDK
Date: Tue, 30 May 2017 10:30:34 +0200 [thread overview]
Message-ID: <1496133037-3014-1-git-send-email-jacekx.piasecki@intel.com> (raw)
From: Michal Jastrzebski <michalx.k.jastrzebski@intel.com>
This patch introduce a mechanism for running dpdk application with parameters
provided by configuration file. New API for cfgfile library allows to create
a cfgfile at runtime, add new section and add entry in a section - opens up
the possibility to have applications dynamically build up a proper DPDK
configuration, rather than having to have a pre-existing one.
A new API for EAL takes a config file data type - either loaded from file,
or built up programmatically in the application - and extracts DPDK parameters
from it to be used when eal init is called. This allows apps to have an alternative
method to configure EAL, other than via command-line parameters.
Testpmd application is used to the demonstrate the new eal API.
If a --cfgfile-path <path> option is passed into command line non EAL section,
then the file is loaded and used by app. If a file called config.ini is present
in current working directory, and no --cfgfile-path option is passed in,
config.ini file will be loaded and used by app.
Currently *.ini file format is supported, but we would like to demonstrate in
v2 how alternative config file formats could be used. Other work planned for v2:
support for subsections – allowing to pass i.e. [DPDK.vdev0] and its parameters,
cleanup to EAL API and testpmd.

cfgfile: add new API functions

eal: add functions parsing EAL arguments
app/testpmd: changed example to parse options from cfg file
