The modern bar is accessed now via yet another address space created just for that purpose and it does not really need FlatView and dispatch tree as it has a single memory region so it is just a waste of memory. Things get even worse when there are dozens or hundreds of virtio-pci devices - since these address spaces are global, changing any of them triggers rebuilding all address spaces. This replaces indirect accesses to the modern BAR with a simple lookup and direct calls to memory_region_dispatch_read/write. This is expected to save lots of memory at boot time after applying: [Qemu-devel] [PULL 00/32] Misc changes for 2017-09-22 Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Reviewed-by: Michael S.
