2018-05-10platform-bus-device: use device plug callback instead of machine_done notifierIgor Mammedov
platform-bus were using machine_done notifier to get and map (assign irq/mmio resources) dynamically added sysbus devices after all '-device' options had been processed. That however creates non obvious dependencies on ordering of machine_done notifiers and requires carefull line juggling to keep it working. For example see comment above create_platform_bus() and 'straitforward' arm_load_kernel() had to converted to machine_done notifier and that lead to yet another machine_done notifier to keep it working arm_register_platform_bus_fdt_creator(). Instead of hiding resource assignment in platform-bus-device to magically initialize sysbus devices, use device plug callback and assign resources explicitly at board level at the moment each -device option is being processed. That adds a bunch of machine declaration boiler plate to e500plat board, similar to ARM/x86 but gets rid of hidden machine_done notifier and would allow to remove the dependent notifiers in ARM code simplifying it and making code flow easier to follow.

This is TYPE_MEMORY_REGION's property. Its getter memory_region_get_addr() uses visit_type_uint64(). Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-Id: <20170607163635.17635-27-marcandre.lureau@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com>
2016-09-27sysbus: Remove ignored return value of FindSysbusDeviceFuncDavid Gibson
Functions of type FindSysbusDeviceFunc currently return an integer. However, this return value is always ignored by the caller in find_sysbus_device(). This changes the function type to return void, to avoid confusion over the function semantics.

2016-01-13sysbus: Don't use hw_error() in machine_init_done_notifiersMarkus Armbruster
platform_bus_map_irq() and platform_bus_map_mmio() use hw_error() to fail. They run in machine_init_done_notifiers, via platform_bus_init_notify() and link_sysbus_device(). Printing CPU registers is not helpful there. Replace hw_error() by error_report(); exit(1). If these are programming errors, it should be replaced by an assertion instead. While there, observe that both functions always return 0, and link_sysbus_device() ignores the return value. Change them to void.

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>
