Hello Jason Lowe-Power, Matthias Jung, Giacomo Travaglini, Andreas Sandberg,
I'd like you to reexamine a change. Please visit
https://gem5-review.googlesource.com/c/public/gem5/+/12249
to look at the new patch set (#4).
Change subject: systemc: If sc_main returns, don't do any more systemc
stuff.
......................................................................
systemc: If sc_main returns, don't do any more systemc stuff.
When sc_main returns, clear out any pending work in the scheduler and
also block the systemc kernel from doing actions which correspond with
the start of simulation.
It's most likely that work like oustanding timeouts might survive past
the end of sc_main, especially if it never officially called sc_stop.
It's also possible for sc_main to return and never actually call
sc_start. In that case, the kernel should not call callbacks of the
various objects (which may no longer even exist), or go through the
initialization phase.
If sc_main is never called at all, then the kernel's actions aren't
gated.
