From the 58 calls in the repository, only 4 set the 'owner' parameter. It is obvious we want the Machine to be the owner of the RAM, so we want to use OBJECT(machine) as owner. We can simplify a bit by passing MachineState to memory_region_allocate_system_memory(). In preparation of this refactor, first drop the 'owner' argument from these 4 uses. $ git grep memory_region_allocate_system_memory hw/ | wc -l 58 Signed-off-by: Philippe Mathieu-Daud=C3=A9 --- hw/alpha/typhoon.c | 2 +- hw/arm/raspi.c | 2 +- hw/hppa/machine.c | 2 +- hw/sparc/sun4m.c | 2 +- 4 files changed, 4 insertions(+), 4 deletions(-) diff --git a/hw/alpha/typhoon.c b/hw/alpha/typhoon.c index 179e1f7658..8489ec335c 100644 --- a/hw/alpha/typhoon.c +++ b/hw/alpha/typhoon.c @@ -851,7 +851,7 @@ PCIBus *typhoon_init(ram_addr_t ram_size, ISABus **isa_= bus, =20 /* Main memory region, 0x00.0000.0000.
