Subject: [PATCH 0/6] memory: Introduce address_space_create(), re-use &address_space_memory
Date: Thu, 19 Aug 2021 16:20:33 +0200 [thread overview]
Message-ID: <20210819142039.2825366-1-philmd@redhat.com> (raw)
Introduce address_space_create() (return .heap allocated AddressSpace)
and return directly &address_space_memory if the root MemoryRegion is
get_system_memory().
This simplifies the 'info mtree' output of some boards. Flatview is
unchanged.
Inspired by this thread:

Based-on: <20210819141527.2821842-1-philmd@redhat.com>
Philippe Mathieu-Daudé (6):
memory: Do not increase refcount on global system_memory region
memory: Introduce address_space_create()
memory: Have cpu_address_space_init() use address_space_create()
hw/dma: Replace alloc() + address_space_init() by
address_space_create()
hw/usb: Replace alloc() + address_space_init() by
address_space_create()
memory: Have address_space_create() re-use global
&address_space_memory
