Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
Referring to Fig.1, a kind of step flow chart of parameter transfer method embodiment of the invention is shown, can specifically include
Following steps:
Step 101, file is transmitted according to parameter, assignment is carried out to target variable.
It should be noted that the board of chip producer production can be provided with reference to DTS file in kernel, in advance will
By DTS (Chinese: source device tree；English: Device tree source) file compiling generate DTB (Chinese: binary device
Tree；English: Device tree binary) parameter assignment is to target variable, and then the case where firmware does not transmit DTB parameter
Under, kernel, which can choose, to be exported by the DTB parameter that the compiling of DTS file generates as target variable, and below step is carried out
Operation.
Illustratively, defining loongson_fdt_blob is target variable, and for obtaining DTB parameter, according to chip, producer is mentioned
The DTB file of confession carries out preassignment to target variable:
Loongson_fdt_blob=__dtb_loongson3_ls7a_begin；
Wherein _ _ dtb_loongson3_ls7a_begin is the mechanism provided by kernel and corresponding chip producer
The DTB file that the DTS file of offer compiles out.
Step 102, in the case where receiving parameter transmitting instruction, the assignment of target variable is updated.
In a particular application, kernel can define a global variable for receive firmware transmitting parameter, such as MIPS (in
Text: the microprocessor without inner interlocked pipelining-stage；English: Microprocessor without interlocked piped
Stages) the undefined variable of platform is void*loongson_fdt_blob；Parameter transmitting instruction is received it is meant that DTB
Parameter for example passes through esys- > of_dtb_addr and is transferred in kernel by firmware, therefore by the DTB parameter assignment of transmitting to target
Variable, i.e., when receiving transmitting instruction:
Loongson_fdt_blob=(void*) (esys- > of_dtb_addr).
Step 103, in the case where not receiving parameter transmitting instruction, the assignment of target variable is kept.
In a particular application, in the case where not receiving parameter transmitting instruction, due in advance to the assignment of target variable
(DTB file) then keeps step 101 to keep the assignment of loongson_fdt_blob, that is, loongson_fdt_blob
For _ _ dtb_loongson3_ls7a_begin.
Step 104, the current assignment of target variable is exported.
Illustratively, when receive parameter transmitting instruction when, that is, execute step 102 when, then by (void*) (esys- >
Of_dtb_addr) the current assignment as loongson_fdt_blob (target variable) is exported, in order to which system is normal
Starting；Otherwise, _ _ dtb_loongson3_ls7a_begin exports the current assignment as target variable, still ensures that and is
The normal starting of system.
In conclusion the technical solution that the application proposes, transmits file according to parameter, assignment is carried out to target variable；?
In the case where receiving parameter transmitting instruction, the assignment of target variable is updated；Parameter transmitting instruction is not being received
In the case of, keep the assignment of target variable；Export the current assignment of target variable.And then can, it is not transmitted in DTB parameter
When, the parameter transmitting file provided using chip producer carries out preassignment to DTB parameter, realize the normal transmitting of DTB parameter, with
The normal starting of guarantee system, improves the stability of system.
Optionally, referring to Fig. 2, the step flow chart of another address conversion method embodiment of the invention is shown, is walked
File is transmitted according to predetermined parameter described in rapid 101, assignment is carried out to target variable, may include steps of:
Step 1011, it gets parms and transmits file.
Wherein, parameter transmitting file is the file of source device tree DTS format.It is, obtaining chip producer in interior core
The DTS file of setting.
Step 1012, parameter transmitting file is converted to the file of binary device tree DTB format.
In a particular application, after being compiled to parameter transmitting file (DTS file), DTB file is generated, e.g.: _ _
dtb_loongson3_ls7a_begin。
Step 1013, the file of DTB format is assigned to target variable as pointer variable.
Illustratively, loongson_fdt_blob=__dtb_loongson3_ls7a_begin.
Optionally, referring to Fig. 3, the step flow chart of another address conversion method embodiment of the invention is shown,
After step 101, the method may include following steps:
Step 105, the target component that firmware is used to carry out DTB parameter transmitting is obtained.
Step 106, it in the case where target component is equal to preset value, determines and does not receive parameter transmitting instruction.
Step 107, it in the case where target component is not equal to preset value, determines and receives parameter transmitting instruction.
Illustratively, after carrying out preassignment to target variable, kernel will test whether firmware has Transfer Parameters, that is,
Judge the value of the esys- > of_dtb_addr (target component).Esys- > of_dtb_addr as DTB Transfer Parameters, when its not
When for NULL (0), that is, illustrate that firmware transmitting has DTB parameter, that is, determine and receive parameter transmitting instruction, kernel can will be consolidated
The DTB parameter assignment of part transmitting executes the operation of step 102, target component is assigned to mesh to loongson_fdt_blob
Variable is marked, with the DTB parameter (preassignment of step 101) in kernel before covering；If firmware does not transmit DTB parameter,
Esys- > of_dtb_addr is 0 (NULL), it is determined that not receive parameter transmitting instruction, is not executed to loongson_fdt_
The assignment of blob also continues to the preassignment for keeping step 101, using the DTB parameter of kernel as loongson_fdt_blob's
Value, so that, when firmware does not have Transfer Parameters, system also can be used normally for the board of chip producer oneself.
Illustratively, loongson_fdt_blob=__dtb_loongson3_ls7a_begin；(the pre- tax of target variable
Value)
If (esys- > of_dtb_addr) (judges whether esys- > of_dtb_addr is 0)
Loongson_fdt_blob=(void*) (esys- > of_dtb_addr) (is not 0, target component is assigned to
Target variable is realized and is updated to the numerical value of target variable).
It should be noted that for simple description, therefore, it is stated as a series of action groups for embodiment of the method
It closes, but those skilled in the art should understand that, embodiment of that present invention are not limited by the describe sequence of actions, because according to
