... it will be used to abstract generic ACPI bits from device that implements ACPI interface. ACPIOSTInfo type is used for passing-through raw _OST event/status codes reported by guest OS to a management layer. It lets management tools interpret values as specified by ACPI spec if it is interested in it. QEMU doesn't encode these values as enum, since it doesn't need to handle them and it allows interface to scale well without any changes in QEMU while guest OS and management evolves in time.

When the patch was posted that became 5c21ce77 (qdev: Realize buses on device realization, 2014-03-12), it included recursive realization and unrealization of devices when the bus's "realized" property was toggled. However, due to the same old worries about recursive realization and prerequisites not being realized yet, those hunks were dropped when committing the patch. Unfortunately, this causes a use-after-free bug (easily reproduced by a PCI hot-unplug action). Before the patch, device_unparent behaved as follows: for each child bus unparent bus ----------------------------. | for each child device | | unparent device ---------------. | | | unrealize device | | | | call dc->unparent | | | '------------------------------- | '----------------------------------------' unrealize device After the patch, it behaves as follows instead: unrealize device --------------------. | for each child bus | | unrealize bus (A) | '------------------------------------' for each child bus unparent bus ----------------------. | for each child device | | unrealize device (B) | | call dc->unparent | '----------------------------------' At the step marked (B) the device might use data from the bus that is not available anymore due to step (A). To fix this, we need to unrealize devices before step (A). To sidestep concerns about recursive realization, only do recursive unrealization and leave the "value && !bus->realized" case as it is. The resulting flow is: for each child bus unrealize bus ---------------------. | for each child device | | unrealize device (B) | | call bc->unrealize (A) | '----------------------------------' unrealize device for each child bus unparent bus ----------------------. | for each child device | | unparent device | '----------------------------------' where everything is "powered down" before it is unassembled.

Like the previous patch did in exec.c, split memory_region_init_ram and memory_region_init_ram_from_file, and push mem_path one step further up. Other RAM regions than system memory will now be backed by regular RAM. Also, boards that do not use memory_region_allocate_system_memory will not support -mem-path anymore. This can be changed before the patches are merged by migrating boards to use the function.
