This is to match the FVP Foundation platform. Priviledged software could query the SYS_ID register in the V2m Motherboard controller to extract platform information: https:// static.docs.arm.com/100961/1110/armv8_a_fp_ug_100961_1110_00_en.pdf In particular: * SYS_ID[31:28] (REV) = Revision Number ** Value = 0x3 -> FVP Foundation v9.6 * SYS_ID[27:16] (HBI) = Board Number ** Value = 0x010 -> FVP Foundation platform * SYS_ID[15:12] (BLD) = Which variant of the GIC memory is implemented in the model ** Value = 0x1 -> (!= legacy VE memory map) * SYS_ID[11:8] (Arch) = Architecture ** Value = 0x1 -> Architectural model (FVP) Change-Id: Ib9395eb872cb925c029077acfdd18e48478f779b Signed-off-by: Giacomo Travaglini <giacomo.travaglini@arm.com> Reviewed-by: Ciro Santilli <ciro.santilli@arm.com> Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/27184 Reviewed-by: Nikos Nikoleris <nikos.nikoleris@arm.com> Maintainer: Nikos Nikoleris <nikos.nikoleris@arm.com> Tested-by: Gem5 Cloud Project GCB service account <345032938727@cloudbuild.gserviceaccount.com> Tested-by: kokoro <noreply+kokoro@google.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, 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.
