This is patch is in regard to issues discussed here: https://www.mail-archive.com/gem5-dev@gem5.org/msg39122.html The aim of this patch is to set a potential fix, and to give more valuable debugging information. It is not known why Kokoro sometimes fails, but it may be due to the Docker service not starting fully prior to execution of the tests within a Docker container. As such a 2 second sleep has been added between starting the Docker service and running the tests. The pulling of the docker images has been separated out to run at the start of testing. This should help us determine whether the issue lays with the pulling of an image or the running of a container. The bash debug flag `-x` has been set so the expansion of each line can be determined upon the event of a failure. This patch will be reverted if it is found to not solve the issue.

This is the gem5 simulator. The main website can be found at http://www.gem5.org A good starting point is http://www.gem5.org/about, and for more information about building the simulator and getting started please see http://www.gem5.org/documentation and http://www.gem5.org/documentation/learning_gem5/introduction. To build gem5, you will need the following software: g++ or clang, Python (gem5 links in the Python interpreter), SCons, SWIG, zlib, m4, and lastly protobuf if you want trace capture and playback support. Please see http://www.gem5.org/documentation/general_docs/building for more details concerning the minimum versions of the aforementioned tools. Once you have all dependencies resolved, type 'scons build/<ARCH>/gem5.opt' where ARCH is one of ARM, NULL, MIPS, POWER, SPARC, or X86. This will build an optimized version of the gem5 binary (gem5.opt) for the the specified architecture. See http://www.gem5.org/documentation/general_docs/building for more details and options. The basic source release includes these subdirectories: - configs: example simulation configuration scripts - ext: less-common external packages needed to build gem5 - src: source code of the gem5 simulator - system: source for some optional system software for simulated systems - tests: regression tests - util: useful utility programs and files To run full-system simulations, you will need compiled system firmware (console and PALcode for Alpha), kernel binaries and one or more disk images. If you have questions, please send mail to gem5-users@gem5.org Enjoy using gem5 and please share your modifications and extensions.
