2015-02-27Create specific config option for "platform-bus"David Gibson
Currently the "platform-bus" device is included for all softmmu builds. This bridge is intended for use on any platforms that require dynamic creation of sysbus devices. However, at present it is used only for the PPC E500 target, with plans for the ARM "virt" target in the immediate future. To avoid a not-very-useful entry appearing in "qemu -device ?" output on other targets, this patch makes a specific config option for platform-bus and enables it (for now) only on ppc configurations which include E500 and on ARM (which always includes the "virt" target).

2014-11-04sysbus: Add new platform bus helper deviceAlexander Graf
We need to support spawning of sysbus devices dynamically via the command line. The easiest way to represent these dynamically spawned devices in the guest's memory and IRQ layout is by preallocating some space for dynamic sysbus devices. This is what the "platform bus" device does. It is a sysbus device that exports a configurably sized MMIO region and a configurable number of IRQ lines. When this device encounters sysbus devices that have been dynamically created and not manually wired up, it dynamically connects them to its own pool of resources. The machine model can then loop through all of these devices and create a guest configuration (device tree) to make them visible to the guest. Signed-off-by: Alexander Graf <agraf@suse.de>
2014-08-25cpus: Define callback for QEMU "nmi" commandAlexey Kardashevskiy
This introduces an NMI (Non Maskable Interrupt) interface with a single nmi_monitor_handler() method. A machine or a device can implement it. This searches for an QOM object with this interface and if it is implemented, calls it. The callback implements an action required to cause debug crash dump on in-kernel debugger invocation. The callback returns Error**. This adds a nmi_monitor_handle() helper which walks through all objects to find the interface. The interface method is called for all found instances. This adds support for it in qmp_inject_nmi(). Since no architecture supports it at the moment, there is no change in behaviour. This changes inject-nmi command description for HMP and QMP.

2014-03-20qdev: Introduce FWPathProvider interfacePaolo Bonzini
QEMU supports firmware names for all devices in the QEMU tree but some architectures expect some parts of firmware path names in different format. This introduces a firmware-pathname-change interface definition. If some machines needs to redefine the firmware path format, it has to add the TYPE_FW_PATH_PROVIDER interface to an object that is above the device on the QOM tree (typically /machine).

2014-03-12hw/core: Introduce QEMU machine as QOM objectMarcel Apfelbaum
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.

2013-04-20qdev: Drop taddr propertiesPeter Maydell
Drop all the infrastructure for taddr properties (ie ones which are 'hwaddr' sized). These are now unused, and any further desired use would be rather questionable since device properties shouldn't generally depend on a type that is conceptually variable based on the target CPU. 32 or 64 bit integer properties should be used instead as appropriate for the specific device.
