Embodiment Construction

[0016] Referring to the accompanying drawings, the content of the present invention will be described with specific examples for its implementation and working process.

[0017] Automatically complete PCIE Port configuration through PCIE devices:

[0018] 1. When the server starts up, it can be known through the PRSNT signal that when the user inserts an X16 device into SLOT A or SLOT B, the other SLOT is not used. Then the PCIE Port can be configured as SLOT A:PCIE LANE(0-7)+PCIE LANE(8-15) through logic control, or as SLOT B:PCIE LANE(15-8)+PCIE LANE(7-0 ), so that the inserted device can get rich PCIE resources.

[0019] like figure 2 As shown, the PCIE LANE marked (1) is a combination of SLOT A X16, the PCIE LANE marked (2) is a combination of SLOT B X16,

[0020] 2. When the server starts up, through the detection of the PRSNT signal, it can be known that the user has checked the two devices on SLOT A / B respectively, and the logic control will configure the PCIE P...

Abstract

The invention provides a PCIE (peripheral communication interface express) intelligent switching method based on a PCIE hot plug function, which belongs to the technical field of servers. For realizing the PCIE intelligent switching design based on the PCIE hot plug function, an X16PCIE port of a CPU (central processing unit) is divided into two X8, and each X8 is switched through PCIE SWITCH; one group of X8 can be switched to PCIELANE (0-7) and also can be switched to PCIELANE (7-0), and the other group of X8 can be switched to PCIELANE (8-15) and also can be switched to PCIELANE (15-8); the configuration of the PCIE port can be automatically completed through PRNST signals of X8 and X16 of SLOTA / B; the configuration of the PCIE port customized by the user is completed through a HOTPLUGCONTROLLER and the CPU. By adopting the method, the port configuration of the CPUPCIE can be automatically adjusted according to a real external PCIE device and the requirement of the customization.

Description

[0001] technical field [0002] The invention relates to the technical field of servers, in particular to a PCIE intelligent switching method based on the PCIE hot plug function. Background technique [0003] The development of today's server technology requires higher and higher IO scalability of the server, and the PCIE resources of each CPU are certain, so how to use these resources flexibly, effectively and rationally is becoming more and more important. It is impossible to automatically adjust the Port configuration of the CPU PCIE according to the actual external PCIE device and customized requirements of the user, so the effective utilization of PCIE resources cannot be realized. Contents of the invention [0004] The purpose of the present invention is to provide a PCIE intelligent switching method based on the PCIE hot plug function, which can automatically adjust the Port configuration of CPU PCIE according to the actual external PCIE equipment and c...
