With: https://gem5-review.googlesource.com/c/public/gem5/+/26466 The ArmSystem reset address (_resetAddr) is always forced by the workload: _resetAddr = workload->entry So there is no possibility to manually specify a reset address. This was not the case before: The resetAddr was forced only if auto_reset_addr was true or if there was an associated bootloader to the kernel image. In that case even if auto_reset_addr was false, the reset address was determined by the bootloader entry. This was also not ideal (but it was working) This patch is cleaning all of this: If you want to have automatic detection (recommended), you would need to set auto_reset_addr (now turned to true by default). This will allow to keep most fs script untouched. If you don't want to use automatic detection, set auto_reset_addr to False and provide your own reset address.

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.
