[SOLVED] Core dump when emulating SPARC with QEMU

jj93 · 2022-09-26 16:16:38

Hi,

I have unsucessfully tried to use qemu-system-sparc on my system.

The program fails to execute even without any arguments (when it should at least reach openbios shell).

The error message:

qemu: fatal: Trap 0x02 (Illegal Instruction) while interrupts disabled, Error state

[1]    6561 IOT instruction (core dumped)  qemu-system-sparc

The back trace from the core dump:

I have briefly taken a look at some of those functions and search several things on google up to page 3. Couldn't find anything meaningful, other than old posts and issues.

I'm afraid troubleshooting this is beyond my skills.

I built my own QEMU from source and it opens correctly up to openbios, no aborts. I did have issues installing solaris afterwards but that may be because of the quick&dirty build. I reviewed the arch package build but there's some many options it's hard to tell.

Should I open a bug report?

Same error on my system, a bug report seems a good idea.

Welcome to archlinux forums.

Thank you.

I created the bug report.

Time to wait now.

I just reviewed this again. The update (v7.1.0-6) the maintainers released fixed the issue.
