The adoption of the gem5 namespace [1] broke aarch64 builds with
the following error:
build/ARM/arch/arm/kvm/base_cpu.cc:198:22: error: aggregate
'gem5::kvm_reg_list regs_probe' has incomplete type and cannot be
defined
In file included from build/ARM/arch/arm/kvm/base_cpu.cc:38:0:
build/ARM/arch/arm/kvm/base_cpu.hh:115:28: note: forward declaration of
'struct gem5::kvm_reg_list'
std::unique_ptr<struct kvm_reg_list> tryGetRegList(uint64_t nelem)
const;
Forward declaring the struct defined in linux/kvm.hh (included in source
file) in the global namespace, rather than the gem5 one fixes the
problem

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.
