[gem5-users] HeteroGarnet SE simulation - Suppressing functional read errors in Network.hh

Hi, I am currently experimenting with *HeteroGarnet* and the *Mesh_XY* topology with the *weight table-based* and *XY routing algorithms*. I discovered something interesting while running the simple *threads.cpp* program (in tests/test-progs/threads/src/threads.cpp) in *SE mode* with the following

[gem5-users] Chiplet Simulation with Gem5

Hi, Does anyone know how to do a chiplet based simulation on the latest Gem5 version with garnet? My basic requirements are: running distributed C++ applications (using multi-threading) on the Gem5 O3CPYU type, having the ability to control the number of cores on individual chiplet dies (even one

[gem5-users] SPEC2k17 V1.1.9 with gem5 gives errors in SE mode

Hello, As the title says, I am trying to run the SPEC benchmarks (v1.1.9) on gem5 v23.0.1.0 on an Ubuntu 20.04 LTS host machine with SE mode of simulation on DerivO3CPU. Whenever I run the simulation, I keep getting a similar error for all Intrate benchmarks (base version) saying that unrecognized

[gem5-users] Re: gcc compilation with m5_dump_stats/reset_stats

Hi Ayan, Can you show how you have coded the m5_dump_stats and m5_reset_stats? I would also recommend using multiple m5_dump_reset_stats(0,0) commands if you just want to print the statistics for a specific code regions. Also did you correctly compile the m5utils as described here?: https://www.

[gem5-users] More system calls support in SE mode

Hi! I was wondering if there was a way to implement more syscalls for the X86 ISA. I am talking about modifying the *arch/x86/linux/syscall_tbl64.cc *to include functions for unimplemented syscalls like fork, kill, etc. or for ignored syscalls like access. I know that the emulation functions are

[gem5-users] Can I run a ".exe" executable on SE/FS mode in gem5?

Hi! I am working on a project that requires me to analyze a Windows executable (64-bit compiled using Mingw-w64). I know that I can use wine to run it on the host Linux (Ubuntu) system. But since I want to analyze this executable is there a way to execute it on gem5 (with or without wine)? P.S. I

[gem5-users] How does gem5 handle application pointers? (X86 build)

Hi all! I have a very simple C code where I am initializing a char variable using malloc and storing a string inside it using strcpy. Then I am simply trying to change the first character of the string. Here is a snippet of what my code looks like: FILE *filp char *fname = (char*)malloc(strlen("W

[gem5-users] How to set data breakpoints/watchpoints in FS/SE modes

Hi! I am trying to figure out ways in which I can use gem5's pre-existing SimObjects to set data watchpoints/breakpoints. If there exist no SimObjects to do that I can also create my own but for that, I need to understand the concept of data watchpoints. Can anyone help me with either of these? F

[gem5-users] Help with a debug flag

Hi! I am trying to use a debug flag with gem5.opt (X86 isa) called Stack via the command build/X86/gem5.opt --debug-flag=Stack. The problem I am getting no output from this flag. The reason I wanted to use it is to print the user call stack when I run a binary using configs/example/se.py config fi
