This is the line I have used: build/X86/gem5.opt configs/example/se.py --cpu-type=TimingSimpleCPU –cpu-cycle=2GH-n 8 --cmd=m5threads/tests/test_omp -o '8 8' REAL SIMULATION info: Entering event queue @ 0. Starting simulation... warn: Attempting to open special file: /sys/devices/system/cpu. Ignoring. Simulation may take un-expected code path or be non-deterministic until proper handling is implemented. fatal: syscall getdents (#78) unimplemented. Memory Usage: 829528 Kbytes Any clue on how to run a multithreaded program in SE mode without using ruby?

We are trying to use gem5 full-system but we are encountering some issues when mounting the rootfs/initramfs. This is our setup: - gem5 on branch develop from https://gem5.googlesource.com/public/gem5 (c493d2c4ad) - BBL on branche master from https://github.com/riscv/riscv-pk.git (e8e6b3aa) - Linux 5.10, checkout on v5.10 tag (2c85ebc57) This is what we tried so far: -Compiling BBL with and without specifying the DTS: No changes -Compiling BBL with Linux vmlinux OR Image as payload: No changes -Compiling Linux with an minimalistic initramfs which only prints a "Hello World" from the init script: No changes -Using fs_linux.py OR run_riscv.py as the entry point: No changes Here are the boot logs from different experiments, with only the last lines of the boot log to keep this mail short: = This is the boot log when specifying a disk-image param, using fs_linux.py: Command: $GEM5_FAST_BIN -v \ -d $GEM5_OUTPUT \ $GEM5_HOME/configs/example/riscv/fs_linux.py \ --cpu-type=AtomicSimpleCPU \ --cpu-clock=1GHz \ -n 1 \ --disk-image=$DISK \ --kernel= \ --mem-type=DDR4_2400_4x16 \ --mem-size=4GB \ --command-line="root=/dev/vda ro console=ttyS0" m5 terminal: Terminal 0 ...

[gem5-users] Issue in using HMC in SE mode
Hello,
I am using gem5.20 and trying to run the hello world program in se.py using
HMC, but I’m getting an error saying I’m trying to initiate an orphan node.
build/X86/gem5.opt configs/example/se.py
--cmd=tests/test-progs/hello/bin/x86/linux/hello --mem-type=HMC_2500_1x32

raise RuntimeError("Attempt to instantiate orphan node")
RuntimeError: Attempt to instantiate orphan node
Does anyone know what might be the cause and the solution for this?
Thank you,
Hessa.
