[gem5-users] Re: gem5 Linux Version 4.18

Hi Giacomo, Thank you for your reply. Yes, I am using v22.0.0.2, and I have ensured that the recompiled bootloader binaries are in the M5_PATH. If that issue is resolved, then perhaps this shows that there is a similar issue that isn't necessarily a FEAT_PAuth problem, but has a similar output.

[gem5-users] Re: gem5 Linux Version 4.18

Hi Sam, 1. Are you using v22.0.0.2 or simply v22.0.0.0? (The FEAT_PAuth problem has been resolved in v22.0.0.2 so it is not really an open issue) 2. If using the v22.0.0.2, could you make sure you rebuild the bootloader and make M5_PATH point to it? Let me know if this works Kind

[gem5-users] Re: Gem5 segfaults in build/X86/cpu/o3/fetch.cc

Hi Gagan, The problem is that the CPU doesn't have an ISA object as a child. Most likely, the function `createThreads()` wasn't called on the CPU instance. You need to set all of this up *in the python configuration*, not in the C++ models. Solving this problem is difficult if you're using the

[gem5-users] Re: Gem5 segfaults in build/X86/cpu/o3/fetch.cc

Thank you for the reply Tom. In my case, I have been able to fix it by supplying the "decoder=ArchDecoder()" parameter to the cpu_class constructor when switch_cpus is first initialized. (Line 465 in Simulation.py) > switch_cpus = [cpu_class(switched_out=True, cpu_id=(i), decoder=ArchDecoder())
