In my own research I did not find out about these inferiors, so I was wondering why "info threads" did only show one cpu. Maybe gdb could inform the user about unattached inferiors when using "info threads" -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1921092 Title: gdbstub debug of multi-cluster machines is undocumented and confusing Status in QEMU: Confirmed Bug description: Working with Zephyr RTOS, running a multi core sample on mps2_an521 works= fine.
