2014-08-18memory: convert memory_region_destroy to object_unparentPaolo Bonzini
Explicitly call object_unparent in the few places where we will re-create the memory region. If the memory region is simply being destroyed as part of device teardown, let QOM handle it. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-05-07docs/memory.txt: Fix document on MMIO operationsFam Zheng
.impl.valid should be .impl.unaligned and the description needs some fixes. .old_portio is removed since commit b40acf99b (ioport: Switch dispatching to memory core layer). Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
2013-11-05docs/memory.txt: Clarify and expand priority/overlap documentationPeter Maydell
The documentation of how overlapping memory regions behave and how the priority system works was rather brief, and confusion about priorities seems to be quite common for developers trying to understand how the memory region system works, so expand and clarify it. This includes a worked example with overlaps, documentation of the behaviour when an overlapped container has "holes", and mention that it's valid for a region to have both MMIO callbacks and subregions (and how this interacts with priorities when it does).

2013-10-14docs/memory: Explictly state that MemoryRegion priority is signedMarcel Apfelbaum
When memory regions overlap, priority can be used to specify which of them takes priority. By making the priority values signed rather than unsigned, we make it more convenient to implement a situation where one "background" region should appear only where no other region exists: rather than having to explicitly specify a high priority for all the other regions, we can let them take the default (zero) priority and specify a negative priority for the background region.
