Data interaction method and calculation equipment

Abstract

The embodiment of the application provides a data interaction method and calculation equipment, and relates to the field of IT (Information Technology). The method and the equipment can improve data interaction efficiency of a BIOS (Basic Input Output System) and a BMC (Baseboard Management Controller). The method includes: copying a first data package of a first application to a first shared interaction region by the BIOS through a PCIE (PCI(Peripheral Component Interconnect) Express) channel; acquiring the first data package from the first shared interaction region by the BMC through a memory channel; determining an instruction, of acquiring the first data package by a second application, by the BMC according to a mapping relationship of the first application and the second application.The BMC includes virtual PCIE equipment. The virtual PCIE equipment includes I / O memory space. The I / O memory space includes the first shared interaction region. The embodiment of the application is applied to a data transmission scene containing the BIOS and the BMC.

Description

technical field [0001] The present application relates to the field of information technology (Information Technology, IT), and in particular to a data interaction method and a computing device. Background technique [0002] With the accelerated development of IT technology, the requirements for the efficiency and reliability of server data processing are getting higher and higher, so the basic input output system (Basic Input Output System, BIOS) and baseboard management controller (Baseboard Management Controller) in the server , BMC) The efficiency and reliability requirements for data interaction between BMCs are also getting higher and higher. Among them, BIOS is a set of programs solidified on the read-only memory (ROM) chip in the server, which stores the most important basic input and output programs of the computer, the self-test program after power-on and the system self-starting program. Wait. The BMC is usually included in the module or the main circuit board o...

Problems solved by technology

[0003] For example, the SMBIOS data of a server whose power interface is more than 8 pins can usually reach about 110 kilobytes (Kb). low efficiency

Moreover, since IPMI is a server / client (Client / Server, CS) architecture, BMC acts as a server, BIOS acts as a client, and does not support BMC actively sending messages to BIOS

The current BMC active notification BIOS mechanism is mainly triggered by General Purpose Input Output (GPIO). Due to the limitation of the number of GPIO pins, the flexibility of BMC active notification is reduced.

In addition, during the BMC restart process, the events reported by the BIOS cannot be received, which will lead to data loss.

And BT only supports synchronous transmission, not asynchronous transmission
