* memory_region_allocate_system_memory - Allocate a board's main memory
|
|
* @mr: the #MemoryRegion to be initialized
|
|
* @owner: the object that tracks the region's reference count
|
|
* @name: name of the memory region
|
|
* @ram_size: size of the region in bytes
|
|
*
|
|
* This function allocates the main memory for a board model, and
|
|
* initializes @mr appropriately. It also arranges for the memory
|
|
* to be migrated (by calling vmstate_register_ram_global()).
|
|
*
|
|
* Memory allocated via this function will be backed with the memory
|
|
* backend the user provided using "-mem-path" or "-numa node,memdev=..."
|
|
* if appropriate; this is typically used to cause host huge pages to be
|
|
* used. This function should therefore be called by a board exactly once,
|
|
* for the primary or largest RAM area it implements.
|
|
*
|
|
* For boards where the major RAM is split into two parts in the memory
|
|
* map, you can deal with this by calling memory_region_allocate_system_memory()
|
|
* once to get a MemoryRegion with enough RAM for both parts, and then
|
|
* creating alias MemoryRegions via memory_region_init_alias() which
|
|
* alias into different parts of the RAM MemoryRegion and can be mapped
|
|
* into the memory map in the appropriate places.
|
|
*
|
|
* Smaller pieces of memory (display RAM, static RAMs, etc) don't need
|
|
* to be backed via the -mem-path memory backend and can simply
|
|
* be created via memory_region_init_ram().

* MachineClass:

* @min_cpus: minimum number of CPUs supported. Default: 1
|
|
* @default_cpus: number of CPUs instantiated if none are specified. Default: 1
|

* @get_hotplug_handler: this function is called during bus-less
|
|
* device hotplug. If defined it returns pointer to an instance
|
|
* of HotplugHandler object, which handles hotplug operation
|
|
* for a given @dev. It may return NULL if @dev doesn't require
|
|
* any actions to be performed by hotplug handler.
|
|
* @cpu_index_to_instance_props:
|
|
* used to provide @cpu_index to socket/core/thread number mapping, allowing
|
|
* legacy code to perform maping from cpu_index to topology properties
|
|
* Returns: tuple of socket/core/thread ids given cpu_index belongs to.
|
|
* used to provide @cpu_index to socket number mapping, allowing

|
* a machine to group CPU threads belonging to the same socket/package
|
|
* Returns: socket number given cpu_index belongs to.
|
|
* @hw_version:
|
|
* Value of QEMU_VERSION when the machine was added to QEMU.
|
|
* Set only by old machines because they need to keep
|
|
* compatibility on code that exposed QEMU_VERSION to guests in
|
|
* the past (and now use qemu_hw_version()).
|
|
* @possible_cpu_arch_ids:
|
|
* Returns an array of @CPUArchId architecture-dependent CPU IDs
|
|
* which includes CPU IDs for present and possible to hotplug CPUs.
|
|
* Caller is responsible for freeing returned list.
|
|
* @get_default_cpu_node_id:
|
|
* returns default board specific node_id value for CPU slot specified by
|
|
* index @idx in @ms->possible_cpus[]
|
|
* @has_hotpluggable_cpus:
|
|
* If true, board supports CPUs creation with -device/device_add.
|
|
* @default_cpu_type:
|
|
* specifies default CPU_TYPE, which will be used for parsing target
|
|
* specific features and for creating CPUs if CPU name wasn't provided
|
|
* explicitly at CLI
|
|
* @minimum_page_bits:
|
|
* If non-zero, the board promises never to create a CPU with a page size
|
|
* smaller than this, so QEMU can use a more efficient larger page
|
|
* size than the target architecture's minimum. (Attempting to create
|
|
* such a CPU will fail.) Note that changing this is a migration
|
|
* compatibility break for the machine.
|
|
* @ignore_memory_transaction_failures:
|
|
* If this is flag is true then the CPU will ignore memory transaction
|
|
* failures which should cause the CPU to take an exception due to an
|
|
* access to an unassigned physical address; the transaction will instead
|
|
* return zero (for a read) or be ignored (for a write). This should be
|
|
* set only by legacy board models which rely on the old RAZ/WI behaviour
|
|
* for handling devices that QEMU does not yet model. New board models
|
|
* should instead use "unimplemented-device" for all memory ranges where
|
|
* the guest will attempt to probe for a device that QEMU doesn't
|
|
* implement and a stub device is required.
