Hi, It is possible you are not able to bring up secondary CPUs when booting Linux. I would suggest you to have a look at the dmesg dump to check if there’s a problem.
Just in case, please update bootloaders by either recompiling them from source or by downloading them at https://www.gem5.org/documentation/general_docs/fullsystem/guest_binaries Kind Regards Giacomo From: Zhang Li via gem5-users <gem5-users@gem5.org> Date: Friday, 17 December 2021 at 12:51 To: gem5-users@gem5.org <gem5-users@gem5.org> Cc: Zhang Li <terminal.zhan...@outlook.com> Subject: [gem5-users] Only one cpu was working in a multicore FS simulation in gem5 v21.1.0.2 Dear, Recently, I found a strange differences in statistics when I run exactly the same command in gem5 v20.1.0.0 and v21.1.0.2 respectively. In v20.1.0.0, all of the 8 cpus have committed instruction. However, in v21.1.0.2, all cpus except cpu0 have a statistics of 0 instruction committed, it seems that only cpu0 was working. Could I get some clues about this? Best regard!
