[Bug 1921092] Re: how do i delete this bug?

[Peter Maydell]

In general, you don't need to delete bugs that turn out to be user
error, or edit the description/title; just mark them as 'invalid',
perhaps with a comment about what turned out to be the cause. That
leaves the trail of what was going on for future readers who might be
going down the same path as you.

There are actually a couple of things we should do here in upstream
QEMU:

* we should document the process for using the debugstub with multi-cluster 
board models like the mps2-an521
* we should check whether we are doing the right/most appropriate thing when 
the user connects to the debug stub and is only attaching to one 'inferior' -- 
it sounds from your report like the un-attached inferior is left permanently in 
the 'stopped' state. Maybe that's what the gdb protocol requires, but it seems 
a bit unhelpful.

I'm going to update the bug status/text accordingly.


** Summary changed:

- how do i delete this bug?
+ gdbstub debug of multi-cluster machines is undocumented and confusing

** Changed in: qemu
       Status: Invalid => Confirmed

** Description changed:

- no bugs here
+ Working with Zephyr RTOS, running a multi core sample on mps2_an521 works 
fine. Both cpus start.
+ Trying to debug with options -s -S the second core fails to boot.
+ 
+ Posted with explanation also at: https://github.com/zephyrproject-
+ rtos/zephyr/issues/33635
