Description
The pcie-switch device models a logical PCI Express switch that PCI Express devices can be connected to. The switch needs memory-space objects connected, representing the three PCI Express address spaces 'configuration', 'I/O' and 'memory'. The switch itself should be connected to a PCI Express bridge device.

Attribute List
bridge
Required attribute; read/write access; type: Object.

Upstream PCI bridge object, which must implement the pci-bridge interface.

bus_number
Optional attribute; read/write access; type: Integer.

PCI bus number of this bus. In most cased this is 0, but some exceptions exist.

conf_space
Required attribute; read/write access; type: Object.

Memory-space object representing the PCI configuration space.

interrupt
Optional attribute; read/write access; type: o|n|[o*].

One or more interrupt device objects that implements the pci-interrupt interface. This attribute only has to be set if the bridge does not handle PCI interrupts.

io_space
Required attribute; read/write access; type: Object.

Memory-space object representing the PCI I/O space.

memory_space
Required attribute; read/write access; type: Object.

Memory-space object representing the PCI memory space.

pci_devices
Optional attribute; read/write access; type: [[iio]|[iioi]*].

((id, function, object)*) id is pci device id. function is the pci device logical function. object is the pci device itself, which must implement the 'pci-device' interface.

send_interrupt_to_bridge
Optional attribute; read/write access; type: Integer.

If non-zero (default), interrupt will be routed to the PCI bridge as well as the interrupt devices.

sub_bus_number
Optional attribute; read/write access; type: Integer.

Subordinate PCI bus number for this bus.
