[Public] Hi Pau,
Does the host system have 4 CPUs available for KVM to use? I have seen similar errors occasionally with even 2 CPUs and simply rerunning the simulation seemed to fix it. Unfortunately, I am not a KVM expert so I am not entirely sure how to make it more robust. -Matt From: Pau Galindo Figuerola via gem5-users <gem5-users@gem5.org> Sent: Friday, March 22, 2024 10:47 AM To: The gem5 Users mailing list <gem5-users@gem5.org> Cc: Pau Galindo Figuerola <pau.galindo.figuer...@estudiantat.upc.edu> Subject: [gem5-users] GPU FS Multiple CPU Caution: This message originated from an External Source. Use proper caution when opening attachments, clicking links, or responding. Hi all, I'm trying to run GPU FS with 4 CPU. That's because I want to replicate a real APU device that has 4 x86 CPUs with 2 threads each. When running it in FS along with a Vega10 GPU I'm facing the following error: M5 Terminal Output: [ 0.332000] smpboot: CPU0: AMD Fake gem5 x86_64 CPU (family: 0xf, model: 0x25, stepping: 0x1) [ 0.336000] Performance Events: Broken PMU hardware detected, using software events only.
