Description

The adjustment method of middle-and-high-ranking configuration of Basic Input or Output System (BIOS) and power supply interface module

[technical field]

The present invention relates to the adjustment method of middle-and-high-ranking configuration of a kind of Basic Input or Output System (BIOS) and power supply interface module.

[technical background]

The basic input-output system BIOS of computing machine (Basic Input/Output System) also be core system software (CSS), and it is positioned at the bottom of all softwares, is the important bridge that software and hardware is linked up.Mainly finish the initialization of each hardware in the computing machine, and provide various and interface hardware communications for upper strata operating system.(DOS for example, all direct or indirect framework of all functions WINDOWS) is in the various services that BIOS provided to we can say operating system.So the importance of BIOS in total system is self-evident.Vivid says that if a computing machine is not installed WINDOWS, the user can also select other operating system, as LINUIX, DOS, difference only is whether the friendly degree of man-machine interface and function be perfect, if but do not have BIOS, and computing machine will be the scrap iron a pile, any work all can't be finished.Exactly because this importance of BIOS makes its debugging operation irregularity loaded down with trivial details, one careless mistake all can dysfunction occur in use in the future, cause immeasurable loss.

And ACPI modules A CPI (Advanced Configuration and PowerInterface Specification) is as a module of among the BIOS equipment being carried out power management and configuration, and its function is the most important thing especially.In the computer nowadays technology, mobile platform is more and more widely used.Operation is in the open air had higher requirement to the travelling performance of computing machine in the fields such as ecommerce, military affairs, space flight.Power-saving technology becomes the main bottleneck of mobile platform development.Just think, if any notebook computer long power lead in tow all where, it is just not all right to have left fixed socket, and who also can use it, and the good advantage of travelling performance is with all gone.So, how to prolong working time of battery, extend the life of a cell, directly determined the performance of notebook computer.And everything all depends on the quality that the ACPI modular program is write.

The ACPI modular program has following characteristics:

Programming language is special, the ASL language of use be different from any popular programming language (as C, PASCAL, ASSEMBLER), its grammer is difficult to be grasped, logicality is poor.

The program format write is strict.

The fault freedom of the compiler of ASL language own is poor, and many implicit mistakes can't be examined out.

Program is carried out behind the scenes, can't see intermediate result.

Above characteristics have determined the ACPI module to be easy to make mistakes, and comprise grammar mistake, logic error.And mistake is difficult to be captured and follow the tracks of, because system collapses already or dies during wrong the generation, so can't know the concrete position of carrying out of program at all.Entirely by rule of thumb with the conjecture update routine, make the development efficiency of whole BIOS become very low.

At present, industry does not also have the special method that this module is effectively debugged, and there is following defective in the hardware tools that uses:

Need peripheral hardware support (for example serial ports).But it is too fast that computer peripheral equipment upgrades, and (for example serial ports has been on the verge of to eliminate at present, and most computers have not been with serial ports, or reduce other peripheral hardwares according to the specific (special) requirements needs.) if peripheral hardware do not exist or undesirable, can't use the hardware debug instrument at all;

Needing increases a debugging machine, links to each other with target machine, is used for showing Debugging message.Each debugging is line again all, and the configuration serial ports uses very inconvenient and the increase debugging cost;

Owing to need external equipment, will introduce uncertain factors such as apparatus factor, line factor, disturbing factor.So the precision of debugging and reliability are all very undesirable;

From the target machine to the debug machine, must increase delay through processes such as coding, transmission, decodings, make debugging speed slower.

[summary of the invention]

The technical matters that institute of the present invention desire solves provides a kind of cost reduction, simple to operation, applied widely, the middle-and-high-ranking configuration of Basic Input or Output System (BIOS) that debugging speed is fast and debugging efficiency is high and the adjustment method of power supply interface module.

The technical solution adopted in the present invention is: the adjustment method of middle-and-high-ranking configuration of a kind of Basic Input or Output System (BIOS) and power supply interface module comprises step:

In the ACPI block code of desire debugging, add Debugging message;

Compile and be burnt in the target machine to the code that contains described Debugging message;

The program that system's operation is debugged is moved debugging acid on target machine;

Described debugged program is put into the data of input/output system district with feedback data,

It is characterized in that: the flow process when described debugging acid moves comprises:

Debugging acid is with start address place, pointed data of input/output system district;

System judges that debugging acid detects current pointer and whether pointed to the last item data in the data of input/output system district, if the judgment is Yes, will detect and whether will finish debugging; If the judgment is No, continue to carry out:

The data of debugging acid reading pointer indication from the data of input/output system district;

Debugging acid with data presentation on the target machine screen;

Debugging acid adds one with the data pointer value;

Bolt down procedure or the step cycle of returning " debugging acid is with start address place, pointed data of input/output system district " are carried out.

The technique effect that the present invention reached is: without any need for the peripheral hardware support, be not subjected to the constraint of machine hardware configuration, the scope of application is extensive; Debugging acid in the operation of this machine, need not add debugging machine fully, reduces debugging cost; Need not special preparation, easy to use; Debugging speed is fast, can not influence the working environment of computing machine because of adding debugging code, and Debugging message and program are carried out and reached synchronously, do not have hardware delay; According to the Debugging message that shows, can know the position that program is performed rapidly, locate erroneous point fast, improved debugging efficiency greatly.

[description of drawings]

The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 1 is a workflow diagram of the present invention.

[embodiment]

The roughly workflow of adjustment method of the present invention is as follows:

One, in ACPI modules A CPI (the Advanced Configurationand Power Interface Specification) code of desire debugging, adds Debugging message;

Two, compile and be burnt in the target machine to the code that contains Debugging message;

Three, on target machine, move debugging acid;

Four, behind the operation debugging acid, can debug according to Debugging message shown on target machine.

In conjunction with process flow diagram as described in Figure 1, it is as follows that the present invention is described in detail in detail:

Step 1, beginning;

Step 2 adds the Debugging message that will show in debugged ASL code;
