This commit specializes the Resource class into specific sub-types. The `Resource`, `CustomResource` and `CustomDiskImageResource` classes have been deprecated in favor of the `AbstractResource` subclasses. Custom Resources can be created via the resource specialization constructor. Resources can be obtained via the gem5-resource infrastructure with the `obtain_resource` function. Fully implemented: - DiskImageResource - BinaryResource - KernelResource - BootloaderResource - FileResource - DirectoryResource Partially implemented: - SimpointResource - CheckpointResource While the schema of the resource.json file has changed, efforts have been made to ensure backwards compatibility is maintained during this transition. Tests are included in this commit to verify this feature works as expected. **Note:** The Simpoint tests are disabled in this commit, to be reenabled when Simpoint resource specialization is fully incorporated here: https://gem5-review.googlesource.com/c/public/gem5/+/67339 Change-Id: I77277ecaffc7abc86db08526aacc0b606ef04fe8 Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/67175 Tested-by: kokoro <noreply+kokoro@google.com> Reviewed-by: Bobby Bruce <bbruce@ucdavis.edu> Maintainer: Bobby Bruce <bbruce@ucdavis.edu>
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, 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 these tools. Once you have all dependencies resolved, type 'scons build/<CONFIG>/gem5.opt' where CONFIG is one of the options in build_opts like ARM, NULL, MIPS, POWER, SPARC, X86, Garnet_standalone, etc. This will build an optimized version of the gem5 binary (gem5.opt) with the the specified configuration. See http://www.gem5.org/documentation/general_docs/building for more details and options. The main source tree includes these subdirectories: - build_opts: pre-made default configurations for gem5 - build_tools: tools used internally by gem5's build process. - configs: example simulation configuration scripts - ext: less-common external packages needed to build gem5 - include: include files for use in other programs - site_scons: modular components of the build system - 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 may need compiled system firmware, kernel binaries and one or more disk images, depending on gem5's configuration and what type of workload you're trying to run. Many of those resources can be downloaded from http://resources.gem5.org, and/or from the git repository here: https://gem5.googlesource.com/public/gem5-resources/ If you have questions, please send mail to gem5-users@gem5.org Enjoy using gem5 and please share your modifications and extensions.
