The prior art generally scales the entire start-up process in its entirety, for example, by setting up and debugging to minimize the amount of information output by all modules at a low level, but in some environments where high level debugging is required, the amount of information printed is still significant. Aiming at the technical defects, the application provides a BIOS debugging information output scheme, wherein a debugging register with a mapping relation with the starting sequence of all running modules in each starting stage is constructed so as to store a debugging identification for determining whether the corresponding running module prints the debugging information, and in the debugging process, only the running module with the debugging identification being the printing debugging information outputs the debugging information, so that the output quantity of the debugging information is controlled, the on-site debugging and development timeliness is enhanced, and the debugging efficiency is improved.
Fig. 1 is a flowchart of a method for outputting BIOS debug information according to an embodiment of the present application. Referring to fig. 1, the BIOS debug information output method includes:
s11: and setting starting sequences for all the operation modules in each starting stage respectively to obtain starting sequences corresponding to all the operation modules in each starting stage.
In this embodiment, first, a start sequence is set for all the operation modules in each start stage, so as to obtain a start sequence corresponding to all the operation modules in each start stage. The BIOS startup phase is divided into SEC, PEI, DXE, BDS, and in these startup phases, each startup phase includes a plurality of operation modules, some operation modules need to output debug information, and some operation modules do not need to output debug information. According to the embodiment, the purpose of improving the debugging information quantity and increasing the timeliness of on-site debugging and development is achieved by refining the debugging module. For example, referring to FIG. 2, each of the start-up phases A will beThe corresponding starting sequence obtained after the starting sequence is set by each running module is A 1 、A 2 、…、A n Likewise, the various operating modules in the start-up phase B and start-up phase M are also configured in this way. It should be noted that, generally, the starting sequence may be set in a customized manner according to the service requirement, but for a module that cannot set the starting sequence in a customized manner, that is, a module with a fixed starting sequence, the starting sequence is set according to the inherent sequence.
S12: constructing a debugging register with a mapping relation according to the arrangement sequence of all the operation modules in the starting sequence, and storing the debugging identification of the corresponding operation module by using the debugging register; wherein the debug flag characterizes whether to print debug information during the debug process.
