Hi Sam, I have to say I successfully managed to boot Linux 4.14 with a pristine v22.0.0.2. What’s the content of m5out/system.terminal? Also, could you provide me the ArmRelease you are using? This should be a list of enabled Armv8.X extensions.

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. What can I do to verify if FEAT_PAuth is enabled? If not, what else should I do to isolate the issue? Again, thank you for your help!

(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 Regards Giacomo From: Thomas, Samuel <samuel_tho...@brown.edu<mailto:samuel_tho...@brown.edu>> Date: Monday, 1 August 2022 at 22:16 To: gem5 users mailing list <gem5-users@gem5.org<mailto:gem5-users@gem5.org>> Subject: [gem5-users] gem5 Linux Version 4.18 Hi all, We recently upgraded our gem5 project to be compatible with gem5 version 22, and are working with a modified version of Linux. We had been working from kernel version 4.14 (following the instructions from https://www.gem5.org/documentation/general_docs/fullsystem/building_arm_kernel). When we use this kernel version with the most recent changes to gem5, the simulator cannot fully boot, and it seems as though this might be due to the "FEAT_PAuth" being utilized (cited as an open issue in the v22.0.0.2 release notes). When we use the out of the box Linux kernel binary that comes with the guest binaries (from https://www.gem5.org/documentation/general_docs/fullsystem/guest_binaries), the simulator works well and the system boots. Is the source for the Linux version 4.18 that comes with the guest binaries available? Are there any patches that we can apply to the Linux v4.18 commit? Thank you in advance for your help!
