Embodiment Construction

[0042] The present invention will be further described below with specific embodiments in conjunction with the accompanying drawings.

[0043] The invention discloses a method for realizing hot plugging of a PCIe card, the first embodiment of which is shown in Figure 3, comprising the following steps:

[0044] S301. Set a set of hot-swap circuits controlled by ACPI firmware on the system bottom board for the plug-in cards including multiple PCIe devices.

[0045]Unlike the prior art that provides each PCIe device with a set of hot-swap circuits including power control lines, indicator lights, buttons, slots, etc., in the embodiment of the present invention, the plug-in card that includes multiple PCIe devices is viewed as As a whole, only one set of hot-swap circuits are set on the system backplane. The hot-swapping circuit feeds back the insertion or removal event of the plug-in card to the firmware supporting ACPI on the backplane, and accepts the control of the ACPI firmwa...

Abstract

The invention publishes a method which realizes a PCIe card hot swap of bus accelerated of the peripheral device interface, including: First, the bottom of the system includes multiple PCIe card- installed equipment, a set of hot swap circuit controlled by the senior configuration and power management ACPI firmware; Then ACPI firmware handling the matter that the card is inserted or removed fed back by hot-circuit, and combining the card operating system to run a hot swap operation. The present invention also opens a system backplane of PCIe hot swap. The method and the implementation of this invention can realize the card's overall hot swap of a number of PCIe equipment cards through modifying the support-detail of the hot swap support of ACPI firmware, while reducing the number of hot-line support in the system, can reduce hardware complexity, reduce costs and streamline operational steps.

Description

technical field [0001] The invention relates to electronic technology, in particular to a method and device for realizing hot plugging of PCI Express (PCI Express, peripheral component interface acceleration bus) plug-in cards. Background technique [0002] At present, PCI (Peripheral Component Interconnect, peripheral component expansion interface) has become a bus standard commonly supported by computer equipment. Its biggest feature is its hot-swappable function, which allows users to connect peripheral devices without shutting down or suspending the application computer. The addition or removal of equipment can improve the availability of the system, and it is also convenient to replace the faulty equipment in time when the equipment fails. With the development of computer technology and the continuous expansion of application fields, PCIe technology with higher transmission rate based on PCI standard modification has emerged, and a new hot-plug (Hot-Plug) technology nee...
