* machine: query dump-guest-core machine propertyMarcel Apfelbaum2015-03-111-0/+6
| | | | | | | | | | | | | | | | | | | | | Running qemu-bin ... -machine pc,dump-guest-core=on leads to crash: x86_64-softmmu/qemu-system-x86_64 -machine pc,dump-guest-core=on qemu-system-x86_64: qemu/util/qemu-option.c:387: qemu_opt_get_bool_helper: Assertion `opt->desc && opt->desc->type == QEMU_OPT_BOOL' failed. Aborted (core dumped) This happens because the commit e79d5a6 ("machine: remove qemu_machine_opts global list") removed the global option descriptions and moved them to MachineState's QOM properties.

* sysbus: Make devices spawnable via -deviceAlexander Graf2014-11-041-0/+34
| | | | | | | | | | | | | 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. Signed-off-by: Alexander Graf <agraf@suse.de>

| | | | | | | | | | | | | | | | | "iommu" as a switch 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.

The main functional change is to convert QEMUMachine into MachineClass and QEMUMachineInitArgs into MachineState, instance of MachineClass. As a first step, in order to make possible an incremental development, both QEMUMachine and QEMUMachineInitArgs are being embedded into the new types. Reviewed-by: Michael S.
