VIRTUTECH CONFIDENTIAL Previous - Up - Next

Provided by: pci-bus
Class Hierarchy: conf-object → log-object → pci-bus
Interfaces Implemented: log_object, snoop_memory, timing_model, io_memory
Description: The pci-bus device models a logical Peripheral Component Interconnect bus that PCI devices can be connected to. The bus needs memory-space objects connected, representing the three PCI address spaces 'configuration', 'I/O' and 'memory'. The bus itself should be connected to a PCI 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.
