Problems solved by technology

Although there is a table in the BIOS that can change different configurations, when performing clock synchronization tests, our BIOS provides dozens of versions. In order to cooperate with the hardware for different GPIO configurations, if a configuration needs to be changed, we need to provide a version to match Hardware work, wasting time and delaying testing progress

Abstract

The invention provides a GPIO (General-Purpose Input / Output) interface configuration method, system and device, and a readable storage medium. The method comprises the following steps: an interaction protocol of a BMC and a BIOS is configured, and interaction between the BMC and the BIOS is established; GPIO interface configuration information required by a clock synchronization test is obtained; the BMC sets a GPIO interface required by the clock synchronization test through a platform management interface program and sends the GPIO interface to the BIOS, and the BIOS fills corresponding setting information into a GPIO interface configuration table; the BIOS performs GPIO interface configuration according to the GPIO interface configuration table, and performs clock synchronization test. According to the method, the system and the device, the GPIO interface can be quickly configured in an out-of-band mode according to requirements of a clock synchronization test, so that time and manpower are effectively saved.

Description

technical field [0001] The present invention relates to the field of computer technology, and more specifically relates to a configuration method, system, device and readable storage medium of a GPIO interface. Background technique [0002] GPIO interface (General-purpose input / output), the abbreviation of general-purpose input and output interface, the function is similar to P0-P3 of 8051, its pins can be freely used by users through program control, and PIN pins can be used as general-purpose input (GPI) according to practical considerations. ) or general-purpose output (GPO) or general-purpose input and output (GPIO), such as when clk generator, chip select, etc. The GPIO interface has the advantages of low power consumption, small package, low cost, and simple wiring, and is widely used in computing devices. [0003] In computing devices such as servers and storage, in many cases, software and hardware need to cooperate to work together. Clock synchronization test is on...
