This commit adds part of RISC-V Cryptography Extensions v1.0.1 to gem5. Include the following instructions: Zbkx: xperm8: Crossbar permutation (bytes) xperm4: Crossbar permutation (nibbles) Zknd: aes64ds: AES decrypt final round (RV64) aes64dsm: AES decrypt middle round (RV64) aes64im: AES Decrypt KeySchedule MixColumns (RV64) aes64ks1i: AES Key Schedule Instruction 1 (RV64) aes64ks2: AES Key Schedule Instruction 2 (RV64) Zkne: aes64es: AES encrypt final round instruction (RV64) aes64esm: AES encrypt middle round instruction (RV64) aes64ks1i: AES Key Schedule Instruction 1 (RV64) aes64ks2: AES Key Schedule Instruction 2 (RV64) Zknh: sha256sig0: SHA2-256 Sigma0 instruction sha256sig1: SHA2-256 Sigma1 instruction sha256sum0: SHA2-256 Sum0 instruction sha256sum1: SHA2-256 Sum1 instruction sha512sig0: SHA2-512 Sigma0 instruction (RV64) sha512sig1: SHA2-512 Sigma1 instruction (RV64) sha512sum0: SHA2-512 Sum0 instruction (RV64) sha512sum1: SHA2-512 Sum1 instruction (RV64) Zksed: sm4ed: SM4 Encrypt/Decrypt Instruction sm4ks: SM4 Key Schedule Instruction Zksh: sm3p0: SM3 P0 transform sm3p1: SM3 P1 transform Change-Id: Ide3e6a4ce903be09dfb3e6b702c9dbcf74a35afb Co-authored-by: Yang Liu <numbksco@gmail.com> Co-authored-by: Fan Yang <1209202421@qq.com> Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/60949 Reviewed-by: Jason Lowe-Power <power.jg@gmail.com> Tested-by: kokoro <noreply+kokoro@google.com> Maintainer: Jason Lowe-Power <power.jg@gmail.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.
