Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
At present, a firmware engineer needs to add a lot of debugging information during the working period of the solid state disk, then the triggered debugging information is transmitted to a terminal through a CPU, and the engineer performs problem positioning according to the output debugging information. As shown in fig. 1, or when the solid state disk finds itself abnormal during execution, it is also necessary to output abnormal information to the terminal, and sometimes even all states of the solid state disk need to be output. The output of the debugging information needs to occupy CPU resources, and if the information is too much, the execution of the core task by the CPU is influenced, so that the performance is reduced, the service quality is unstable, and other consequences are caused.
For example: the solid state disk can periodically detect the temperature of the working environment, and periodically outputs debugging information 1: the size of this piece of information is 28 bytes, and for example, after each power-on, the solid state disk initializes each module, and when each module initialization is completed, debug information 2 is output: "% module initial access", this information is also 28Byte, if there are 20 initialization modules, the CPU needs to output the debug information of 28Byte 20 ═ 560Byte during the entire initialization period, which may affect the power-on time of the solid state disk to some extent.
In the conventional art, in order to solve such a contradiction, improvements are generally made from the following aspects: 1. the number of debugging information is reduced as much as possible; 2. the length of each piece of debugging information is reduced as much as possible; 3. a cache is opened in the solid state disk, debugging information is firstly written into the cache, and then the debugging information is output to a terminal by a CPU once when the system is idle. These approaches, however, do not solve the problem at all, but rather limit the ease of engineering debugging.
The present invention provides a new method for outputting debug information based on the above technical problems, and is expected to solve the limitations of the prior art.
In one embodiment, as shown in fig. 2, a method for outputting debugging information based on a solid state disk is provided, where the method includes:
step 202, obtaining a debugging information output request based on a solid state disk;
step 204, establishing a debugging information mapping table according to the debugging information output request based on the solid state disk;
step 206, obtaining a debugging information keyword sent by the solid state disk;
step 208, debugging information corresponding to the debugging information keywords is inquired in a debugging information mapping table;
and step 210, outputting a debugging result according to the inquired debugging information.
The core idea is that an engineer creates a mapping table outside a solid state disk, and each entry in the mapping table is composed of two members as shown in the following table: the key word is an index value corresponding to the character string, the index value accounts for the fixed size of the memory, and is related to the total number of the character strings in the mapping table, wherein the index value is assumed to be 1Byte, and the index value is represented by hexadecimal in table 1.
In one embodiment, the step of creating the debug information mapping table according to the debug information output request based on the solid state disk further includes: sequentially creating a plurality of debugging information items in a debugging information mapping table, wherein the debugging information items comprise: debugging information texts and corresponding debugging information keywords; the length of the debugging information text can be any size, and the length of the debugging information keywords is fixedly set.
In particular, reference is made to the following table:
| key word | Debug information |
| 00h | Current Temperature is％d |
| 01h | ％d module initial success |
| … | … |
With reference to the working principle of the debugging information shown in fig. 5, taking the two pieces of debugging information shown in the above table as an example, if an engineer wants to output the pieces of debugging information "Current Temperature is% d" and "% d module initial success", the map is initialized first, the initial map is empty, and the engineer may add an entry in the map according to the information content that needs to be output.
Specifically, the engineer wants to output the debug information "Current Temperature is% d", search the mapping table, find that there is no debug information in the mapping table, create a new entry, fill the debug information of the entry with "Current Temperature is% d", fill the key value of the entry with 00h (because it is the first entry of the mapping table), as shown in the first entry in the above table. It will be appreciated that the engineer may create multiple items in sequence, and that modifications and deletions may be made to the contents of the items.
The engineer outputs 00h (1Byte) and a% d-type argument (4Byte) in the firmware, assuming that the actual value of the% d-type argument (4Byte) is 20h, i.e. the CPU only needs to output 5 bytes of data. Compared with the prior art, the solid state disk needs to output 560 bytes of debugging information, so that the information output quantity is greatly reduced. Next, the terminal 1 obtains a debugging information keyword sent by the solid state disk, for example: 00 h. And inquiring debugging information corresponding to the debugging information key words in the debugging information mapping table, specifically, inquiring that the corresponding information is 'Current Temperature is% d' according to the content in the mapping table. Finally, a debugging result, for example, "Current Temperature is 20 h", is output according to the queried debugging information.
In the embodiment, the request is output by acquiring the debugging information based on the solid state disk; establishing a debugging information mapping table according to a debugging information output request based on the solid state disk; acquiring debugging information keywords sent by a solid state disk; inquiring debugging information corresponding to the debugging information keyword in a debugging information mapping table; and outputting a debugging result according to the inquired debugging information. The method for only outputting the keywords in the debugging process of the solid state disk by constructing the debugging information mapping table outside the solid state disk system solves the problem that the performance of the solid state disk is influenced by excessive debugging information, substantially greatly improves the output efficiency of the debugging information, and further improves the convenience of debugging by engineers.
In an embodiment, as shown in fig. 3, a method for outputting debugging information based on a solid state disk is provided, where the step of acquiring a debugging information keyword sent by the solid state disk further includes:
step 302, obtaining debugging information keywords and actual parameters sent by a solid state disk;
step 304, debugging information texts corresponding to the debugging information keywords are inquired in a debugging information mapping table;
and step 306, outputting a debugging result according to the inquired debugging information text and the actual parameters.
In an embodiment, as shown in fig. 4, a method for outputting debugging information based on a solid state disk is provided, where the step of outputting a debugging result according to a queried debugging information text and an argument in the method includes:
step 402, analyzing the debugging information text by calling a debugging information text analysis tool;
and step 404, adding the actual parameter to the corresponding debugging information text according to the analysis result to obtain a final debugging result text.
Specifically, referring to fig. 5 in combination, in this embodiment, an engineer receives data of 5 bytes on the terminal 1, where the data are 00h (1Byte) and 20h (4Byte), respectively, and the two data cannot be interpreted by themselves, the engineer needs to query a mapping table, find that the debugging information corresponding to the keyword 00h is "Current Temperature is% d", and then the engineer needs to invoke an analysis tool (usually, a very simple analysis tool developed by the engineer) capable of analyzing the syntax of the C language to execute the following C language: "Current Temperature is% d", 20 h. This line of C language will appear as a complete character burst on terminal 2: current Temperature is 20 h. The final engineer wants to obtain debugging information, the mapping table lookup and the analysis process are all completed by the analysis tool, the host resources where the analysis tool is located are utilized, and the execution of the solid state disk cannot be influenced.
Finally, debug information "% d module initial success" and corresponding keyword "01 h" are added to the mapping table, and the above steps are repeated.
From the perspective of solid state disk firmware, the advantages of this embodiment include at least the following:
first, the size of the debug information actually output by the solid state disk CPU is greatly reduced, and in this example, the debug information of 28 bytes is reduced to 5 bytes. And no matter how large the original debugging information is, the size of the debugging information can be reduced to 1Byte + real parameter size under the technology, and if the debugging information does not have real parameters, the size can be reduced to 1 Byte.
Second, the engineer does not have to worry about reducing the output of debug information.
And finally, the performance of the solid state disk is hardly influenced.
It should be understood that although the various steps in the flow charts of fig. 2-4 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
