71ae9e94d9 pc: Move option_rom_has_mr/rom_file_has_mr globals to MachineClass
This way, these settings can be simply set on the corresponding
machine_options() function, instead of requiring code in
pc_compat_*() functions.

32c18a2dba kvm: add support for -machine kernel_irqchip=split
This patch adds the initial plumbing for split IRQ chip mode via
KVM_CAP_SPLIT_IRQCHIP. In addition to option processing, a number of
kvm_*_in_kernel macros are defined to help clarify which component is
where.

98cec76a70 machine: Set MachineClass::name automatically
Now all TYPE_MACHINE subclasses use MACHINE_TYPE_NAME to generate the
class name. So instead of requiring each subclass to set
MachineClass::name manually, we can now set it automatically at the
TYPE_MACHINE class_base_init() function.

076b35b5a5 machine: add default_ram_size to machine class
Machines types can have different requirement for default ram
size. Introduce a member in the machine class and set the current
default_ram_size to 128MB.

For QEMUMachine types override the value during the registration of
the machine and for MachineClass introduce the generic class init
setting the default_ram_size.

Add helpers [K,M,G,T,P,E]_BYTE for better readability and easy usage

9850c6047b migration: Allow to suppress vmdesc submission
We now always send a JSON blob describing the migration file format as part
of the migration stream. However, some tools built around QEMU have proven
to stumble over this.

This patch gives the user the chance to disable said self-describing part of
the migration stream. To disable vmdesc submission, just add

  -machine suppress-vmdesc=on

to your QEMU command line.

33cd52b5d7 sysbus: Make devices spawnable via -device
Now that we can properly map sysbus devices that haven't been connected to
something forcefully by C code, we can allow the -device command line option
to spawn them.

For machines that don't implement dynamic sysbus assignment in their board
files we add a new bool "has_dynamic_sysbus" to the machine class.
When that property is false (default), we bail out when we see dynamically
spawned sysbus devices, like we did before.

Add Intel IOMMU emulation to q35 chipset and expose it to the guest.
1. Add a machine option. Users can use "-machine iommu=on|off" in the command
line to enable/disable Intel IOMMU. The default is off.
2. Accroding to the machine option, q35 will initialize the Intel IOMMU and
use pci_setup_iommu() to setup q35_host_dma_iommu() as the IOMMU function for
the pci bus.
3. q35_host_dma_iommu() will return different address space according to the
bus_num and devfn of the device.
