2017-03-20vpp: Reporting update related to VPPMartin Klozik1-1/+1
VSPERF reports were updated to contain vSwitch name. In case of VPP, it is not possible to read its version if VPP is not running. Thus VSPERF was enhanced to support tool version check during its runtime. This mechanism can be enhanced to support e.g. VNF in the future.

2017-02-13pylint: Fixing pylint errors and warningsgoldammx1-2/+1
All python files must reach pylint score 10/10. This will be regularly verified by Jenkins jobs to keep constant code quality. VSPERF specific pylintrc file was updated according to the vsperf coding standards. Distro version included in reports will be slightly different, due to migration to new python package distro. Previously used platform.distro() will be deprecated since python 3.7.

2016-10-27teststeps: Generic support of step driven testsMartin Klozik1-1/+1
In the past, step driven testcases were supported only by integration testcases. This patch adds generic support of TestSteps for both integration and performance testcases. Step driven test were improved to support modification of existing deployment. As part of the patch a refactoring of traffic controllers were performed. Traffic controllers were modified to support trafficgen-off and trafficgen-pause modes in all possible ways of trafficgen invocation.

2016-04-14sriov: Support of SRIOV and Qemu PCI passthroughMartin Klozik1-2/+2
Generic support of SRIOV has been added. Virtual interfaces can be used in multiplei scenarios instead of physical NICs. Virtual functions can be directly accessed from VM by PCI passthrough method. Another option is to use VFs with vSwtich to evaluate impact on performance. Additonal modifications: * Automatic detection of NIC details has been added to simplify configuration. * Obsoleted configuration options have been removed. * Logging usage within vsperf script was fixed. * Vsperf main was refactored and final cleanup function added. * Configurable forwarding mode of TestPMD executed inside VM.

2016-03-21integration: Support of integration testcasesMartin Klozik1-0/+38
Generic support for integration testcases with first set of tests for vswitch testing. New test option "TestSteps" has been introduced to define test step by step directly in configuration file. In case that this concept will be accepted, there are plenty of possibilities for future improvements. For example: * use it also for performance tests without explicit call of validation methods * introduce step macros for repetitive scenarios, so new tests can be easily written * further generalization, which would go beyond usage of controllers and will operate directly with vswitch, vnf and trafficgen objects Change-Id: Ifad166c8ef9cfbda6694682fe6b3421e0e97bbf2 JIRA: VSPERF-212 Signed-off-by: Martin Klozik <martinx.klozik@intel.com> Reviewed-by: Maryam Tahhan <maryam.tahhan@intel.com> Reviewed-by: Al Morton <acmorton@att.com> Reviewed-by: Christian Trautman <ctrautma@redhat.com> Reviewed-by: Brian Castelli <brian.castelli@spirent.com>

 *  Copyright (C) 1995, 1996  Gero Kuhlmann <gero@gkminix.han.de>
 *
 *  Allow an NFS filesystem to be mounted as root. The way this works is:
 *     (1) Use the IP autoconfig mechanism to set local IP addresses and routes.
 *     (2) Construct the device string and the options string using DHCP
 *         option 17 and/or kernel command line options.
 *     (3) When mount_root() sets up the root file system, pass these strings
 *         to the NFS client's regular mount interface via sys_mount().
 *
 *
 *	Changes:
 *
 *	Alan Cox	:	Removed get_address name clash with FPU.
 *	Alan Cox	:	Reformatted a bit.
 *	Gero Kuhlmann	:	Code cleanup
 *	Michael Rausch  :	Fixed recognition of an incoming RARP answer.
 *	Martin Mares	: (2.0)	Auto-configuration via BOOTP supported.
 *	Martin Mares	:	Manual selection of interface & BOOTP/RARP.
 *	Martin Mares	:	Using network routes instead of host routes,
 *				allowing the default configuration to be used
 *				for normal operation of the host.
 *	Martin Mares	:	Randomized timer with exponential backoff
 *				installed to minimize network congestion.
 *	Martin Mares	:	Code cleanup.
 *	Martin Mares	: (2.1)	BOOTP and RARP made configuration options.
 *	Martin Mares	:	Server hostname generation fixed.
 *	Gerd Knorr	:	Fixed wired inode handling
 *	Martin Mares	: (2.2)	"0.0.0.0" addresses from command line ignored.
 *	Martin Mares	:	RARP replies not tested for server address.
 *	Gero Kuhlmann	: (2.3) Some bug fixes and code cleanup again (please
 *				send me your new patches _before_ bothering
 *				Linus so that I don' always have to cleanup
 *				_afterwards_ - thanks)
 *	Gero Kuhlmann	:	Last changes of Martin Mares undone.
 *	Gero Kuhlmann	: 	RARP replies are tested for specified server
 *				again. However, it's now possible to have
 *				different RARP and NFS servers.
 *	Gero Kuhlmann	:	"0.0.0.0" addresses from command line are
 *				now mapped to INADDR_NONE.
 *	Gero Kuhlmann	:	Fixed a bug which prevented BOOTP path name
 *				from being used (thanks to Leo Spiekman)
 *	Andy Walker	:	Allow to specify the NFS server in nfs_root
 *				without giving a path name
 *	Swen Thümmler	:	Allow to specify the NFS options in nfs_root
 *				without giving a path name. Fix BOOTP request
 *				for domainname (domainname is NIS domain, not
 *				DNS domain!). Skip dummy devices for BOOTP.
 *	Jacek Zapala	:	Fixed a bug which prevented server-ip address
 *				from nfsroot parameter from being used.
 *	Olaf Kirch	:	Adapted to new NFS code.
 *	Jakub Jelinek	:	Free used code segment.
 *	Marko Kohtala	:	Fixed some bugs.
 *	Martin Mares	:	Debug message cleanup
 *	Martin Mares	:	Changed to use the new generic IP layer autoconfig
 *				code. BOOTP and RARP moved there.
 *	Martin Mares	:	Default path now contains host name instead of
 *				host IP address (but host name defaults to IP
 *				address anyway).
 *	Martin Mares	:	Use root_server_addr appropriately during setup.
 *	Martin Mares	:	Rewrote parameter parsing, now hopefully giving
 *				correct overriding.
 *	Trond Myklebust :	Add in preliminary support for NFSv3 and TCP.
 *				Fix bug in root_nfs_addr(). nfs_data.namlen
 *				is NOT for the length of the hostname.
 *	Hua Qin		:	Support for mounting root file system via
 *				NFS over TCP.
 *	Fabian Frederick:	Option parser rebuilt (using parser lib)
 *	Chuck Lever	:	Use super.c's text-based mount option parsing
 *	Chuck Lever	:	Add "nfsrootdebug".
