The embodiment of the invention provides a hot plug processing method, device and system. The hot plug processing method includes the steps that a CPU generates register configuration information relevant to PCI-E equipment according to hot plug request messages; the CPU sends the register configuration information to a PCI-E switch chip; the CPU receives register configuration completion messages sent by the PCI-E switch chip, and generates hardware control signals of the PCI-E equipment; the CPU sends the hardware control signals to a general input / output controller; the CPU judges whether hot plug processing of the PCI-E equipment is completed according to register numerical value messages. According to the hot plug processing method, device and system, the CPU directly controls the PCI-E equipment to conduct hot plug, the problem of limitation of I2C addresses of I2C devices is solved, and more PCI-E equipment capable of being hot plugged is supported and expanded.
Description
technical field [0001] Embodiments of the present invention relate to computer hot-swap technology, and in particular, to a hot-swap processing method, device and system. Background technique [0002] The hot-swapping of high-speed peripheral component interconnection standard (Peripheral Component Interconnection Express, referred to as PCI-E) equipment has a great effect on improving the reliability, availability, and maintainability (Reliability, Availability, Serviceability, referred to as RAS) of the computer system. important role. [0003] figure 1 It is a schematic diagram of a hot-swap technical solution in the prior art, such as figure 1 As shown, at present, the solution for realizing the hot plugging of PCI-E equipment is an integrated circuit bus expander (Inter-Integrated Circuit Expander, referred to as I 2 C Expander) through I 2 The C protocol reads and writes the registers related to the hot-swappable controller inside the PCI-E switch chip, and then th...
