The following AArch64 CMOs were flagged as warnNotFail even if they are actually implemented and there is no reason for them to fail: MISCREG_DC_IVAC_Xt MISCREG_DC_ZVA_Xt MISCREG_DC_CVAC_Xt MISCREG_DC_CVAU_Xt MISCREG_DC_CIVAC_Xt This is likely coming from AArch32 (those CMOs are unimplemented in AArch32). Please note: this patch is not changing anything behaviorally; the warnOnFail flag is not considered in AArch64 unless the unimplemented flag is also set (and this was not the case for those CMOs) Change-Id: I40396016703b9eb48f69b0eb710d077f8c2b146b Signed-off-by: Giacomo Travaglini <giacomo.travaglini@arm.com> Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/61685 Reviewed-by: Andreas Sandberg <andreas.sandberg@arm.com> Reviewed-by: Richard Cooper <richard.cooper@arm.com> Tested-by: kokoro <noreply+kokoro@google.com> Maintainer: Andreas Sandberg <andreas.sandberg@arm.com>
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.
