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 present invention provides a method, system, device and storage medium compatible with the TXT function and the ASD function. The method includes: reading the ASD flag in the SRAM during startup, and detecting whether the ASD flag is the first Numerical value; In response to the ASD flag being not the first numerical value, close the debugging interface of the CPU, and open the TXT function of the BIOS; in response to the ASD flag being the first numerical value, open the debugging interface of the CPU, And turn off the TXT function of the BIOS; and in response to turning off the TXT function of the BIOS, reset the ASD flag bit to a second value. Through the cooperation of BIOS and BMC, the present invention allows the server to support the ASD debugging function in addition to the TXT function by default, flexibly compatible with the two contradictory functions, and more conducive to the use and maintenance of the server by users.

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 ...
