Problems solved by technology

The existing technology focuses on the solution after using the BMC to perform remote debugging through the PECI link. It is an optimization scheme for the ASD function, and does not involve the TXT function of the BIOS (Basic Input Output System, Basic Input Output System). , just starting from the ASD function itself, without considering the compatibility of ASD and TXT functions

Abstract

The invention provides a method, system and device compatible with a TXT function and an ASD function and a storage medium. The method comprises the steps: reading an ASD flag bit in a static random access memory in a startup process, and detecting whether the ASD flag bit is a first numerical value; in response to the situation that the ASD flag bit is not the first numerical value, closing a debugging interface of a CPU, and opening a TXT function of a BIOS; when the ASD flag bit is responded to be the first numerical value, a debugging interface of a CPU is opened, and a TXT function of a BIOS is closed; and in response to closing the TXT function of the BIOS, resetting the ASD flag bit to a second numerical value. Through cooperation of the BIOS and the BMC, the server can support the ASD debugging function on the basis of supporting the TXT function by default, the two functions which originally contradict each other are flexibly compatible, and a user can use and maintain the server more conveniently.

Description

technical field [0001] The present invention relates to the server field, and more specifically refers to a method, system, device and storage medium compatible with TXT and ASD functions. Background technique [0002] In the field of servers, TXT (Trusted Execution Technology) function is a technology provided by Intel to users to ensure the security of server data. letter environment. ASD (At-Scale Debug, large-scale debugging) function is a remote debugging technology provided by BMC (Baseboard Management Controller, baseboard management controller), which allows users to use the network out-of-band, through PECI between BMC and CPU (Platform Environment Control Interface, platform environment control interface) link, to debug the server, such as grabbing CPU register information, etc. However, the TXT function and the ASD function are two mutually exclusive functions, because the Debug (debugging) interface of the CPU needs to be opened to start the ASD debugging, and ...
