Hi, I'm seeing a repeatable alignment exception running m68k system mode on armv7l (arm cortex a9) following this commit: "fa947a667fceab02f9f85fc99f54aebcc9ae6b51 is the first bad commit commit fa947a667fceab02f9f85fc99f54aebcc9ae6b51 Author: Richard Henderson <richard.hender...@linaro.org> Date: Thu Jul 29 10:45:10 2021 -1000
hw/core: Make do_unaligned_access noreturn While we may have had some thought of allowing system-mode to return from this hook, we have no guests that require this. " With this included I see this in the kernel dmesg log: [10621.993234] Alignment trap: not handling instruction f843b004 at [<b677bb2e>] [10622.000479] 8<--- cut here --- [10622.003609] Unhandled fault: alignment exception (0x811) at 0xb13eed96 [10622.010162] pgd = 45acdb93 [10622.012941] [b13eed96] *pgd=0557a831, *pte=c01ee743, *ppte=c01eec33 As well as bisecting I've verified it is this revision by checking out clean HEAD then reverting just this revision (+ fixing conflicts). The patch itself just seems to be adding QEMU_NORETURN (aka '__attribute__ ((__noreturn__))') which I'd expect to be benign, so I'm not really sure what is going on. I cross-compiled it on Ubuntu using gcc/g++ (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0. Thanks, Mark
