Description
Technical Field
The present invention relates to the field of terminal testing technologies, and in particular, to a method, an apparatus, a medium, and an electronic device for testing clock configuration.
Background
The development platform provides a clock interface for other drivers to obtain clock frequency, set clock frequency, enable clock and the like. The drivers that implement the clock interface are called clock drivers. The implementation principle of setting the frequency interface is to input the reference according to the input clock to be configured and the target frequency of the clock, convert the frequency value into a corresponding multi-path selection value and a frequency division value by combining a chip register manual, and then write the multi-path selection value and the frequency division value into a register corresponding to the clock. The frequency acquisition interface is realized by acquiring a multipath selection value and a frequency division value of the clock register according to the input parameters of the transmitted clock to be acquired, converting the frequency value into a corresponding clock frequency by combining a chip register manual, and returning the clock frequency to a caller. The enabling interface is realized by setting an enabling register of a clock according to an input parameter of the clock to be configured, so that a path switch of a clock path can be switched on or off according to needs. It can be seen that the configuration of a clock relates to the clock to which the multiplexer register address and to which one or more bits are allocated and which clock frequencies are supported; a divide register address and corresponding one or more bits; the register address and corresponding bit are enabled.
The clock path typically includes an optional variety of clock sources, a frequency divider, and a path switch. Specifically, the phase-locked loop generates a high frequency signal and, in turn, divides the clock of various frequencies for use by the module options as needed. The multi-way selection switch selects a clock with a certain frequency to be applied according to requirements. The frequency divider is used to divide the selected clock source to a smaller frequency according to the requirements. The path switch is used for controlling the output of the clock path to be applied.
The clock paths supported by current device chips, similar to the above paths, are hundreds and thousands of clock paths. The clock driver needs to package many clocks supported by the chip into an interface for other drivers to call. And the provided clocks are only interfaces, and the clock drivers are not called by themselves and are only called by other drivers. Each clock is involved with a number of information, including: the conditions of the multi-path selection register, the frequency division register, the enabling register and the supported frequencies, how to judge whether the information configuration related to the clock configured by the clock driver is correct or not and whether the information configuration has missing configuration or not are very important. However, the existing detection means only detects whether the clock driver is loaded successfully or not, the terminal cannot be started normally, the default frequency is read after the terminal is started or the current frequency of a certain clock is read manually, and there is no effective means for testing whether the information configured by the clock is correct or not or whether the information is omitted.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. Unless defined otherwise, technical or scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. As used herein, the word "comprising" and similar words are intended to mean that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items.
To solve the problems in the prior art, embodiments of the present invention provide a method, an apparatus, a medium, and an electronic device for testing clock configuration.
Example 1
The embodiment provides a test method of clock configuration. Referring to the attached figure 1 of the specification, the method comprises the following steps:
s101, obtaining a clock driving configuration file, wherein the clock driving configuration file comprises information of control registers of all clock paths in a chip.
The specific manner of obtaining the clock driving configuration file may include: acquiring a release version file of the chip, wherein the release version file comprises information of control registers of all clock paths in the chip; and converting the release version file of the chip into a clock driving configuration file in an extensible markup language format.
S102, analyzing the clock driving configuration file to obtain clock identifications of the clocks, clock frequency parameters corresponding to the clock identifications and configuration parameters of the control register.
S103, testing whether the configuration parameters and the clock frequency parameters of the control register corresponding to each clock identification are correct or not to obtain a test result.
In S103, in a possible embodiment, testing whether the configuration parameter and the clock frequency parameter of the control register corresponding to each clock identifier are correct specifically includes: firstly, detecting whether the configuration parameters of a GATE register (enabling register) corresponding to a clock identifier are correct or not; then detecting whether the clock frequency parameter corresponding to the clock identification is correct or not; and finally, detecting whether the configuration parameters of the MUX register (multi-path selection register) and the DIV register (frequency division register) corresponding to the clock identification are correct or not.
In a specific embodiment, the information of the control register of each clock path included in the chip in the release version file is generally stored in the form of a table, and a corresponding identifier needs to be set in the table and the file in the xml format so that the table supports conversion into a specific xml file. In this embodiment, converting the release version file of the chip into the clock driving configuration file in the xml format includes: and presetting a specific extensible markup language format structuralization processing code in the terminal to realize the extensible markup language format structuralization processing of the table, so that the table is converted into a file in a specific extensible markup language format.
In the present embodiment, the extensible markup language (XML) format is as follows:
TABLE 1
Therefore, the clock parameter after the structured processing of the extensible markup language format supports the item name differentiation and the configuration of each subsystem (such as sub-modules of GPU, camera, CPU and the like).
In this embodiment, after the xml format structuring process:
clk config is used to configure a specific clock, including the clock name, such as name = "gpu _ core".
clock _ id: xml is mapped with the respective clock associations of the code configuration and clock id. The format occupies 4 bytes, the upper 2 bytes are sys identifiers, and the lower 2 bytes are clock identifiers under specific sys. Such as 0x00010005:0001 represents a sys;0005 represents a certain clock of the sys.
The enable switch corresponds to the gate register address and control bit, e.g., bit3 at 0x8000000 address is used to control switch enable, then gate _ reg =0x8000000, bit_eb =3.
mux register address and control bit, where shift is the bit offset and width is the bit width (number of bits). If 3 bits in total are used to control the mux _ reg =0x8000004, mux _shift =0, mux _width =3, for bit [2 ] of the 0x80000004 address.
div register address and control bit, where shift is the bit offset and width is the bit width (number of bits). If bit [4 ] of the address 0x80000004 is used to control mux selection, mux _ reg =0x8000004, mux _shift =3, mux _width =2.
Freq is the output frequency of various supported clock sources and div frequency division combination, and is also generated by table direct conversion. For a multi-channel clock source, a certain channel is selected by a multi-channel selection switch (setting the value of a MUX register), and frequency division is carried out by a frequency division coefficient (setting the value of a DIV register). The specific format is the output frequency and the corresponding values of the MUX register and DIV register. If the gpu _ core outputs 256M, according to freq = mux _ clk/(div + 1), mux is required to select 512M clock source, div =1; then freq =512000000, mux =2, div =1.
The clock driving configuration file is information acquired in advance, and when a device/terminal is tested for clock configuration, the clock driving configuration file comprises the following steps: the device/terminal is started, the clock driver is initialized, and the clock test module is initialized.
And then, analyzing the clock driving configuration file to obtain the clock identification of each clock, the clock frequency parameter corresponding to each clock identification and the configuration parameter of the control register. The control register comprises a GATE register, a MUX register and a DIV register, and the configuration parameters of the control register comprise: register offset, occupied bit width, register address and clock enable interface.
In another possible embodiment, detecting whether the configuration parameter of the GATE register corresponding to the clock identifier is correct includes: calling a clock enabling interface of the target clock according to the clock handle to open the target clock; calling an acquisition register interface to acquire an enabling bit of the GATE register according to the register address and the enabling bit of the GATE register, and judging whether the value of the acquired enabling bit is 1; calling a clock enabling interface of the target clock according to the clock handle to carry out closing operation on the target clock; and calling an acquisition register interface to acquire the enable bit of the GATE register according to the register address and the enable bit of the GATE register, and judging whether the value of the acquired enable bit is 0 or not.
In a possible embodiment, the determining whether the configuration parameter of the GATE register corresponding to the clock identifier is correct specifically includes: and according to whether the value of the corresponding bit of the target clock is 1 when the target clock is on and whether the value of the corresponding bit of the target clock is 0 when the target clock is off, calling an enabling interface of the target clock to carry out switching operation on the target clock, and determining whether the configuration parameters of the GATE register corresponding to the clock identification are correct when the target clock is on and off and the values of the corresponding bit of the target clock are correct respectively.
In the invention, a clock can support various frequencies, and when the clock frequency parameter corresponding to the clock identification is detected to be correct, the various supported frequencies corresponding to the clock identification need to be detected one by one. Specifically, whether one supporting frequency corresponding to a clock identifier is correct is detected, and then whether the supporting frequency corresponding to the clock identifier which is not detected exists is judged; if the judgment result is yes, detecting a supporting frequency corresponding to the clock identifier which is not detected, and if the judgment result is no, ending the operation of detecting whether the clock frequency parameter corresponding to the clock identifier is correct or not.
Detecting whether a supported frequency corresponding to the clock identifier is correct comprises: acquiring a clock handle of a target clock corresponding to the clock identifier according to the clock identifier; setting the value of the MUX register and the value of the DIV register by calling a setting register interface according to the configuration parameters of the MUX register and the DIV register corresponding to the frequency of the clock identifier; and calling a clock acquisition frequency interface to read the clock frequency according to the clock handle, and judging whether the acquired frequency value is consistent with the frequency value in the clock drive configuration file.
In a possible embodiment, detecting whether a supported frequency corresponding to the clock identifier is correct may further include: acquiring a clock handle of a target clock corresponding to the clock identifier according to the clock identifier; and calling a clock frequency setting interface to set the clock frequency according to the clock handle, calling a clock frequency acquiring interface to read the frequency, and confirming whether the set value is consistent with the acquired return value.

And when detecting whether the configuration parameters of the MUX register and the DIV register corresponding to the clock identifier are correct, group-by-group detection needs to be carried out on the values of the MUX register and the DIV register corresponding to the clock frequency. Detecting whether a group of values of a MUX register and a DIV register corresponding to the clock frequency are correct or not, and then judging whether the MUX register and the DIV register which are not detected and correspond to the clock frequency exist or not; if the judgment result is yes, detecting the values of a group of MUX registers and DIV registers which are not detected and correspond to the clock frequency, and if the judgment result is no, finishing the operation of detecting whether the configuration parameters of the MUX registers and the DIV registers corresponding to the clock identifiers are correct or not.
In one possible embodiment, detecting whether a set of MUX register values and DIV register values corresponding to the clock frequency are correct comprises: acquiring a clock handle of a target clock corresponding to the clock identifier according to the clock identifier; calling a clock frequency setting interface to set the clock frequency according to the clock handle and the corresponding clock frequency value in the configuration file; acquiring the value of a MUX register and the value of a DIV register by calling an acquisition register interface; and judging whether the acquired value of the MUX register and the acquired value of the DIV register are consistent with the value of the MUX register and the value of the DIV register in the configuration file. And after the detection is finished, the test result of the clock configuration parameters is stored, and the result is used for program debugging analysis or test acceptance.
The chip may include a plurality of clocks, and after the configuration parameters and the clock frequency parameters of the control register corresponding to the clock identifier of one clock are correctly tested, it is determined whether clocks which are not tested for the configuration parameters exist in the configuration file. If the judgment result is yes, testing whether the configuration parameters and the clock frequency parameters of the control register corresponding to the clock identification of the clock which is not tested are correct; if the judgment result is negative, the clock configuration test is finished.
In a possible embodiment, the test result is that a mismatch or a mismatch exists, the error position can be found according to the test result, the clock configuration code can be corrected through manual intervention, and the corrected clock configuration can be tested again by adopting the extensible markup language file until the clock configuration is complete and correct.
