Abstract
The invention discloses a dynamic migration system based on a PCI bus. The dynamic migration system comprises the PCI bus (9), a PCI expansion board card A (12) and a PCI expansion board card B (13) and further comprises a PCI bus dynamic switching board A (10) and a PCI bus dynamic switching board B (11). An external interface (8) of the PCI bus dynamic switching board A (10) and an external interface (8) of the PCI bus dynamic switching board B (11) are in both-way connection. When the system is charged, the PCI bus dynamic switching board A (10) is tacitly approved to obtain the bus control right, when the PCI bus dynamic switching board A (10) is abnormal, the PCI bus dynamic switching board B (11) takes over the control right of the PCI bus (9), and dynamic migration of the PCI bus (9) is achieved. The dynamic migration system based on the PCI bus achieves switching of a plurality of PCI main controllers in the system, achieves the migration of the PCI bus and improves the anti-risk capacity of the system.
Description
Technical field
The present invention relates to a kind of dynamic migration system, particularly a kind of dynamic migration system based on pci bus.
Background technology
In the past based on the system of pci bus, comprise: PCI master control borad, pci bus, PCI expansion board clamping, wherein the PCI master control borad comprises: cpu controller, north and south bridge, PCI bridge, the PCI master controller is integrated in the bridge of north and south, the PCI bridge is used for strengthening the bus driver ability of PCI master controller, to realize the bus functionality expansion, the PCI master controller just can drive a plurality of PCI equipment simultaneously like this.But in case the PCI master controller in the system occurs unusually, the equipment after the PCI bridge just can't drive.In the system that reliability is had high requirements, this situation is very fatal, and therefore such system is short of the carrying out safety backup ability, can't guarantee the lasting reliability service of system, can not be applicable to the high reliability application.
Summary of the invention
The object of the present invention is to provide a kind of dynamic migration system based on pci bus, in case solve the problem of the unusual total system of PCI master control borad with regard to paralysing in the traditional PCI bus system.
A kind of dynamic migration system based on pci bus comprises: pci bus, PCI expansion board clamping A, PCI expansion board clamping B also comprise: the dynamic switch boards A of pci bus, the dynamic switch boards B of pci bus; Wherein, the dynamic switch boards A of pci bus is identical with the circuit structure of the dynamic switch boards B of pci bus, and the dynamic switch boards A of pci bus comprises: cpu controller, north and south bridge, PCI bridge, bus switch, BMC controller, I2C controller, pci bus interface, Peripheral Interface.
In the dynamic switch boards of pci bus, the two-way connection between cpu controller and the north and south bridge, the two-way connection between cpu controller and the BMC controller, the two-way connection between north and south bridge and the PCI bridge, the output terminal of bus switch is connected with the input end of north and south bridge, the output terminal of BMC controller respectively with the input end of PCI bridge, the input end of bus switch connects, the two-way connection between BMC controller and the I2C controller, the two-way connection between I2C controller and the Peripheral Interface, the two-way connection between the Peripheral Interface of the Peripheral Interface of the dynamic switch boards A of pci bus and the dynamic switch boards B of pci bus, the pci bus interface of the dynamic switch boards A of pci bus, the pci bus interface of the dynamic switch boards B of pci bus, PCI expansion board clamping A, PCI expansion board clamping B is connected with pci bus respectively.
When system powered on, the dynamic switch boards A of acquiescence pci bus obtained bus control right, and the dynamic switch boards B of pci bus closes closed bus.The BMC controller opens PCI bridge of the dynamic switch boards A of pci bus is opened bus switch simultaneously, and the PCI bridge has been expanded the pci signal except look-at-me, the break-make of bus switch control look-at-me.Accordingly, the BMC controller of the dynamic switch boards B of pci bus cuts out PCI bridge and bus switch.The dynamic switch boards A of pci bus enumerates by the PCI equipment of PCI bridge after to bridge, thereby realizes the visit to PCI expansion board clamping A and PCI expansion board clamping B, and the dynamic switch boards B of pci bus then can't visit PCI equipment.System is normal start after, the BMC controller on every dynamic switch boards of pci bus all can constantly receive the lasting heartbeat signal from cpu controller on the dynamic switch boards of this piece pci bus, and makes and replying.When system normally moved, the BMC controller on the dynamic switch boards A of pci bus constantly sent condition indicative signal to the dynamic switch boards B of pci bus via the I2C controller, the control of the pci bus of the statement dynamic switch boards A of pci bus; I2C controller on the dynamic switch boards B of pci bus directly transfers to the BMC controller after receiving condition indicative signal, and the BMC controller determines according to condition indicative signal whether needs switch.The I2C controller has strengthened I2C signal driving force, realizes that I2C signal plate level is interconnected, and the I2C controller is transparent for the BMC controller in the plate separately.When the dynamic switch boards A of pci bus is unusual, cpu controller will send the heartbeat abnormal signal or stop to send heartbeat signal, the BMC controller receives the heartbeat abnormal signal or detects less than cutting off PCI bridge and bus switch immediately behind the heartbeat signal, abandon the control power to pci bus, send the abnormal state signal simultaneously to the BMC controller of the dynamic switch boards B of pci bus.After the BMC controller of the dynamic switch boards B of pci bus receives the condition indicative signal of the dynamic switch boards A of pci bus, open PCI bridge and bus switch, send order simultaneously to cpu controller, cpu controller will be enumerated again to pci bus after receiving order, and the PCI equipment behind the bridge is given in the storage allocation space.So far, the dynamic switch boards B of pci bus has just taken over the control of pci bus fully, has realized the dynamic migration of pci bus.
The present invention has realized the switching of a plurality of PCI master controllers in the system, has realized the migration of pci bus, and the system that makes can tackle the unusual situation of PCI controller on certain piece even a few PCI master control borads, has improved the ability to ward off risks of system; Be applicable to system stability, reliability are had the very occasion of high request.
